2019 Holiday Episode (video): Family Dinner at RFHPC

It's become a tradition at RadioFreeHPC to celebrate the holidays with a video of the holiday episode. The new logo launches the video: celebrating a truly family style dinner and dreaming big (maybe too creatively, however) as the team exchanges "if-only" gifts!

Click here to see the Director's Cut version of the video followed by the edited audio-only in the usual link below.

South Africa CHPC National Conference

SA Students Get Ready to take ISC by storm


Probably 15% more scintillating than usual, Dan promises as he calls this episode "fantastic"!
Now a 5-day conference with two days of workshops as book-ends, multiple tracks and many speakers, and yes, a very exciting Student Cluster Competition, the CHPC National Conference has developed into a very important event in the HPC/AI world.  Dan takes us through what he saw, who won, and what we can expect at the competition at ISC in 2020, and just how impressive the whole thing was. You've got to hear it.


Why Nobody Should Ever Be Online. Ever


The Big Easy Battles Big Bad Breach: in a segment that wants to be shortened to "Ever.Ever.", Henry focused not just on yet another cybersecurity incident (the ransomware attack on New Orleans), but on the fact that they city, to its immense credit, actually had a plan! Once the problem was detected, plan kicked into action, systems were shut done, damages narrowed if not avoided, and generally good progress on preparedness was on display. Nice job!

Things You Think You Know, But Might Not


Anyone remember tape drives? Some of you do. Some of you work with them now. Well, Jessi asks about tape storage. Is it still necessary? This is very much in Henry's wheelhouse so he covers it. Shahin seems unconvinced, really, but Henry is way closer to actual use cases, so he reluctantly waves it through!

Catch of the Week


Shahin: Covers the RISC-V Summit that was just held in San Jose. With 2,000 attendees, 435 member companies, lots of great talks, and expecting to grow by another 50% next year, and for something that started only in 2010, it's quite a flywheel that's forming. Also, remember that we had the pleasure of having the RISC-V Foundation CEO, Calista Redmond as a special guest of the podcast, so make sure you listen to that episode.

Shahin also notes that the media coverage of the chip space is starting to show that competition is brewing. Comments from vendors about other projects are sounding sharper and sharper!
He also says RISC "started" at Berkeley and Stanford. "What he meant to say" was modern RISC got its big boost there. He says he's fully aware of the history of RISC going all the way back to Turing, Cray, Flynn, IBM 801 (and we cut him off, convinced already!)

Dan: Speaking of sharper competition and what people meant to say: in an interview with CNet, Apple's top brass made a comment about Chromebook vs Apple gear that's also in the category of "what he meant to say was...". Henry skillfully segues into how more and more services are cloud based, and Jessi highlights the importance of the bring-you-own-device (BYOD) trend in schools.

Jessi: Goes over the US Government Accountability Office report on on airline IT outages. Just what you need for the holiday travel season. "One IT malfunction per month" is one stat you can remember.

Henry: The great $50m African IP address heist. IPv4 addresses are in demand and an enterprising person in Africa has parlayed that into a $50m windfall for his crafty self.  Upshot is? You should all consider gifting IPv4 addresses for the holidays!

SC19: Our Visit to the State Fair

SC19 Postview


Our show today is all about what we saw at the “State Fair for Nerds” that is SC19. Where there weren’t any livestock shows or supercomputers carved out of butter, there was a lot to see and hear.
Shahin talks about the European Processor Initiative and conversations that he had with folks from the Barcelona Supercomputing Center, the quantum computing briefing by D-Wave, and a chat with Cold Quanta.

We reiterate the bet between Henry and Dan, where Henry bets Dan that there will be a RISC-V based system on the TOP500 system by SC20. The stakes? The winner gets the dinner of his choice paid for by the loser.

Jessi went to the keynote by Dr. Squires and notes that someone asked him “where did you use HPC systems in your project?” This prompts Jessi to ask us if it’s kosher to have keynotes which don’t necessarily hit directly on HPC. We discuss how there have been non-HPC centric keynote speakers at several SC events in the past….see Al Gore, Alan Alda, Bill Gates, Michael Dell, etc.

Dan brings up the news from NVIDA about how they’ve gathered a consortium of big-time industry players who will be working on adapting ARM processors for accelerated computing. We speculate on whether Fujitsu will be contributing their very sporty new ARM chip to the group, with thoughts of licensing it for use by other vendors. In other NVIDIA news, Azure now has eight GPU instances connected by InfiniBand interconnects.

Why Nobody Should Ever Be Online. Ever


This week Henry has a reason why no one should ever go to a local doctor again. Ever. He cites an article about how a small doctor and dental office service provider suffered a ransomware attack, which meant that the doctors they were managing archiving for could no longer get access to their records. If this can happen to service providers, it can run these smaller providers out of business as HIPPA regulations and fine are onerous. Dan comments that he only goes to vets for medical services (just like Kramer on Seinfeld).

Things You Think You Know, But Might Not


In this installment, Jessi asks the panel about interconnects, why we need them, what they do, and what are your choices. Dan jumps in with discussing Ethernet and InfiniBand, while Henry jokingly brings up Token Ring. More helpfully, Henry discusses proprietary interconnects and things like RDMA and ROCE. Shahin believes he has the definitive answer, which is the start of his Computing 301 Lecture Series. This leads into a slight tangent where we discuss SMP vs. MPP and how coherency at scale is incredibly expensive.

Catch of the Week


Shahin: Talks about a young man who bought his own IBM z/890 mainframe for $350 and installed it in his parent’s basement. Amazing feat. He has it running and now has the only mainframe in his neighborhood. Congrats to Connor. IBM needs to hire this young man and harness his passion.

Jessi:  Getting or giving an Alexa or Google Home device? Better think twice and then think again. Big time security flaws in both devices.

Henry: Has no catch of the week. He’s looking at -14°F and has to go out and shovel snow.

Dan: Biggest tech flops of 2019. Includes We Work, Samsung Fold, hacks of VPNs, Facebook Libre and other ignominious failures.

Did you say logo?


Most of you probably didn't know that RadioFreeHPC even has a logo, Dan thinks as he gives an update on a project to update the logo, in several colors. Getting closer to the sure-to-be-coveted RadioFreeHPC merch we all wanted!

SC19 Student Cluster Competition - Recap

 SC19 Student Cluster Round Up

The show starts in the usual way, with Henry complaining about snow and us laughing at him. Our special guest, student clusterer extraordinaire Jessi Lanum, complains about recording again with Henry in a definite shot across his bow, to everyone’s amusement.

The group discusses their annual SC19 dinner and the new Henry/Dan bet about the future of RISC-V – check out our last show for the specifics.

We talk about our experiences at SC19, including Henry having to give 19 different presentations in a two-day span, which was a very solid performance. Shahin touches on his annual Dead Architecture Society meeting and the great attendance. We also discuss how many active listeners of Radio Free HPC came up to us – and none of them were armed or threatening at all!

The meat of the show is our discussion of the SC19 Student Cluster Competition. We talk about the student configurations, kicked around the pros and cons of the “small is beautiful” movement in the student cluster competition world. "Does the trend towards fewer-bigger nodes mean a re-emergence and eventual re-victory of SMP over MPP?" wonders Shahin. No records in HPL or HPCG, but some good scores regardless. (It's not proven that the high altitude in Denver was not a factor!)

You’ll have to listen to the show or read Dan’s articles in HPCwire or on www.studentclustercomp.com to get the details – it’s probably a good idea to do both just to make sure you’re fully up to speed.

Why No One Should Ever be Online. Ever.

Henry talks with real anger and sadness about a horrific story of a chain of nursing homes that was attacked by ransomware. These nursing homes now don’t know what medication should go to which patient along with a lot of other problems. Everyone agrees that these malicious criminal idiots are getting worse and that something needs to be done about it pronto.

New Feature Alert!

Things That People Think They Know, But Maybe Don’t

Jessi Lanum’s “Things that people think they know, but maybe don’t” is a new feature on the big broadcast. In this inaugural edition, Jessi asks “What is Exascale and why is it important?” The guys all respond and cover her question like ants on a dead possum.

Catch of the Week

Henry:  Notes that the new Star Wars script was almost sold on Ebay after being filched from a careless actor. Sheesh, is nothing private anymore?

Jessi:  Found a company that is using HPC, AI and WRF to help fight forest fires, which is great, given the wildfire season we’ve seen this year. Shahin also highlights the work at UC San Diego.

Shahin:  The newest Crypto500 ranking is out! Bitcoin has taken over the crypto currency world by latest count, see the white paper here, the slides here, and the Medium article here.

Dan:  Dan’s Catch of the Week is dedicated to you, our faithful set of 16 listeners. He lets you know we’d love it if you reach out to us via Twitter or email to let us know what you like, what you don’t like and what we should cover in the future.

Along those lines, right now, before listening to the episode, open up a new tab on your browser and follow us on Twitter. We’re @RadioFreeHPC and as you know, our email address really should be ears@radiofreehpc.com, because we're all ears you see, but for now it is podcast@radio... We'd love to hear from you.

New TOP500 List: Spot The Difference

Live from SC19

In this Breaking News edition of RadioFreeHPC, we look over the newly released TOP500 list in all its glory. We talk about the changes in this version of the list (100 new systems, but none in the top 24), how the major countries stack up against each other, and vendor system share.

We also discuss why this list is so, well, kind of not as exciting as we've got used to, and what we expect to see on future lists. There are some big things coming, but, like your birthday, they’re not here yet. In other conversation, we covered what we’ll be looking for and doing at the show. It’s a no frills episode, done quick and dirty, just how we like it.

Oh, and Henry and Dan find something to new to bet on!

SC19 Student Cluster Competition - Preview

Blood Sweat Glory, But No Tears

“This is a groundbreaking episode of RadioFreeHPC….groundbreaking, I tell you!

We have a very special guest, our first post-millennial commentator, Jessi Lanum who is a Student Cluster Competition veteran and is on the show to give us an insider peek at what it’s like to compete for cluster competition glory. Like a fresh ocean breeze, Jessi adds a lot to this episode with her enthusiasm, wit, and smart pithy comments.

Our topic today is the 2019 Student Cluster Competition which will take place on the show floor of SC’19.

For the few of you who are not already fans of these events, here’s the lowdown: 16 student teams representing universities from around the world have been working their brains out designing, building, and tuning clusters provided by their sponsors. They can use as much hardware as they want, the only limitation is that their systems can’t use more than 3,000 watts during the competition.

When the green flag drops on Monday afternoon, the students will start running a variety of HPC benchmarks and real-world HPC applications. The goal is to get the best/fastest results and thus prove that they have built, tuned, and optimized the best cluster platform. It’s a hugely exciting event. Dan goes over who all is competing this year and what apps they'll be running. We also get a rare inside scoop from Jessi on what it’s like to prep and compete in the cluster competition. It’s both fascinating and fun to hear what they go through during the grueling 46-hour event.

If you want even more information about the Student Cluster Competitions, visit Dan’s site at www.StudentClusterComp.com to find out everything you ever wanted to know – and more. Dan's been covering this competition around the world for about a decade and been taking copious notes!

Why No One Should Ever Be Online. Ever.

Henry discusses how retailer Orvis was pretty much completely owned by hackers. It’s a post-Halloween horror story, as hackers had their hooks into them from August to October, scary stuff. What worse is what they’ll have to do to recover, clean up their systems, and try to put the pieces together.

Catch of the Week:

Jessi tells us about how Palo Alto Networks is providing free network security training, and certification, for veterans – great job Palo Alto Networks!

Henry shares his theory, buttressed by evidence, that the next big race will take place in low earth orbit as vendors race to put up satellites to provide better and faster internet access.

Shahin discusses a blockchain based calendar that he feels will have a big impact in the future.

Dan brings up the "problematic" introduction of the Disney+ streaming application and we all talk the numbers, including how many subscribers they initially nabbed, the pricing, and the impact on competitors.

"What Should I Do Next?", You Ask?

Truth, Trust, and Deepfakes

You never write, you never call, you never send flowers “just because.” But that’s ok, we welcome you back to another scintillating episode of Radio Free HPC anyway. Henry is traveling on yet another business trip, lodged in the Washington, DC area, and not even in his favorite hotel chain. But his reputation as a team player goes back to his days in the bayou, Dan says. And he performs another skillful yet awkward segue from Henry’s swamp origins to the swamp-like nature of the internet, which brings us to our special guest.

What’s true? What’s real? And how can we KNOW it?

We welcome Dave Maher, CTO of internet security company Intertrust, to share with us his deep knowledge of digital communication, identity management, data rights management, cryptography and digital certificates, blockchain, and much else. This whole subject is very much in his wheelhouse.

Dave gave us the run down on Intertrust and his other roles in the cybersecurity arena. Dan opens up the questioning with “Dave, do we really need security on the internet?” Dave, quick on the draw, responded “Well, we really haven’t had it for the last 20 years, so why start now?” which got the conversation off and running. Dave talked about the evolution of the internet and the rising need for security given that the internet has vastly changed since it began so long ago.

The main topic of the conversation is authenticity and truth. With the rise of deepfakes (images or videos that are convincingly falsified), how do we know that what we’re seeing and hearing is created by who we think and is what we think?

This leads to a deep conversation on ways we can verify content so that we know that it’s authentic. There are many ways of approaching it, but some implementation of blockchain seems to be a promising route.

Listen to the pod and get hipped to this very important topic. Shahin keeps saying it's the grand challenge of our time. He might be right.

Preview of Supercomputing '19 - Denver

What's All Happening at SC19 in Denver?


Supercomputing '19 is coming to Denver this year and who better than Rich Brueckner to give us a sneak peak. Super excited to have Rich and his signature laugh on this show again.


In this podcast, the Radio Free HPC team reviews the full list of ancillary events at SC19, and Henry gives us one more reason to stay offline. Oh, and a few predictions.



There's a lot that happens before the exhibit floor on Monday night. Our old pal Rich Brueckner from insideHPC joins us to give us the full rundown.


SC19 Ancillary Events:

HP-CAST. HPE's user group meeting starts things off on Friday, Nov. 14 - Saturday, Nov. 15. This two-day event will be the first HP-CAST meeting with Cray in the fold, so we're looking to some great insight as to how the two companies will merge their product line, partner network, and HPC ecosystems.

Intel HPC Developer Conference. In this two-day event on Sunday, Nov. 15 - Monday, Nov. 16, Intel offers a robust program to connect the HPC community with Intel developers, Intel engineers, and industry experts. "We’ll help you tackle your HPC challenges by offering a wide range of learning opportunities at SC19.

HPC Day with The Next Platform. Making its debut at SC19, HPC Day on Sunday, Nov. 17 is an in-depth day with thought leaders at the front of high performance innovation. In a series of on-stage interviews (no slides) with industry thought leaders, the Next Platform what’s relevant to the future of supercomputing.

Arm HPC User Group. Now in its fifth year, the all-day event takes place on Monday, Nov. 18 at the Curtis Hotel in Denver. "This is not a Marketing event -- we have a full day agenda of strategic partners and end-users from all regions of the world sharing their experiences, best practices, plans, ecosystem advances, and results on Arm-based platforms for HPC applications."

Dell EMC HPC Community. Kicking off at 8:00am on Monday, Nov. 18, the Dell HPC Community meeting will feature keynote presentations by HPC experts and a networking event to discuss best practices in the use of Dell EMC HPC Systems. Attendees will have the unique opportunity to receive updates on HPC strategy, product and solution plans from Dell executives and technical staff and technology partners.

DDN User Group. Starting at 1:00pm on Monday, Nov. 18, the DDN User Group brings together the best and brightest scientists, researchers and technologists to share and learn how leading global HPC organizations are executing cutting-edge initiatives that are transforming the world. The goal of the event is to gather the community during SC to discover how HPC organizations are assessing and leveraging technology to raise the bar on HPC innovations and best practices.

NVIDIA 2019 Special Address. You’re invited to attend the NVIDIA 2019 Special Address from founder and CEO, Jensen Huang. The event takes place 3:00pm - 5:00pm on Monday, November 18. Last year's address featured spectacular cosmology visualizations computed on NVIDIA GPUs. What will be revealed about accelerated computing on stage this year? Don't miss it. You must RSVP to attend.

Beowulf Bash at SC19. After the SC19 show floor closes on Monday night, the Beowulf Bash is the party not to miss. "This year, we thought it would be great to do Stranger Things theme party. There will be 80s-style entertainment, games, the best 80s tribute band. Food, beverages, entertainment, and Eggo Waffles provided.

Hyperion Research HPC Market Briefing Breakfast. Starting at 7:00am on Tuesday, Nov. 19, this informative briefing from Hyperion Research is always standing-room only. Get there early!

Nimbix Lounge Party. On Tuesday night, Nimbix will host its 7th Annual Lounge Party in Denver. "We invite you along with our co-host Intel to enjoy an evening of entertainment, cocktails and delicious food at White Pie."

Lunch and Learn - Getting a Handle on HPC Cloud Costs. Starting at noon on Wednesday, Nov. 20, this lunch event will share the many advantages of using a cloud spend management platform and how to avoid expensive mistakes when migrating HPC workloads to the cloud. This event is recommended for anyone considering the use of cloud for HPC workloads and will be particularly useful for attendees running Slurm, Univa Grid Engine, or open-source Grid Engine. The session will focus on real-world deployment examples and provide technical demonstrations that show how hybrid clouds can be deployed efficiently and cost-effectively across multiple cloud providers.

Check out the insideHPC Events Calendar and send an email to news@insideHPC.com if your organization sponsoring a function at SC19 and you'd like it listed.

Why No One Should Ever Be Online.  Ever.

Henry’s tells us even internet "domain name registrars" are not immune, describing breaches at  NetworkSolutions.com, Register.com and Web.com which eventually led them to ask customers to reset their passwords. They apparently discovered the hack in August 2019 in which customer account information was accessed. [Yes, we're still massaging the title of this segment but looks like the above is gelling, albeit w/o a shorter tweet-friendly version.]

7 Years, 251 Episodes, 17 Listeners

RadioFreeHPC Celebrates a Number in its Prime

Welcome to a historic milestone:  Our 251st Radio Free HPC episode! We’re celebrating 251 rather than 250 for a couple of reasons. First, everyone celebrates round numbers and that’s boring. And 251 is round enough for those who crave them. Second, 251 is a prime number and we all love us some prime numbers, right?

This is not quite a "highlights" show, but a look back at how RadioFreeHPC came about, who came up with the name RadioFreeHPC, how the show has evolved, a bit of "remember when", a few notable episodes, and the meteoric rise of its listenership!

We discuss the early days, with each of us sharing some of our favorite moments. As the episode continues, we talk about how particular features have become part of the show over time, like “Catch of the Week”, “Henry Newman’s Why No One Should Ever Be Online. Ever”, and the semi-occasional “Why AI Is Our Doom” from Dan.

Here are a couple of choice pictures both of which link to the same holiday special that includes a video where Dan and Henry discuss the ideal gift for Henry!






Did You Say Prizes?

We also discuss fantastic prizes for anyone who has listened to all 251 of our episodes. Reach out to us on Twitter (@Radiofreehpc) or via email to let us know if you qualify and what prize you’d like. Oh, and you have to listen to this episode to learn what the prizes are.

Thank you our listeners, we could do it without you – we have, we must have – but it's totally no fun if we actually know about it.

Here's to the next so many episodes. We need another number in its prime to celebrate, so feel free to propose a good one.

Fragile: Python, sudo, AI

How Many Episodes, Did You Say?!

The show is geographically skewed today with all three hosts on the west coast. Henry is gracing Seattle with his presence, resulting in plunging coffee inventories and skyrocketing sushi prices.

The first item of discussion is a problem in the scientific software world. There’s a bug in Python scripts that caused different results in identical routines run on different operating systems. For example, the results on macOS Maverick and Windows 10 were significantly different than results from the same application run on Ubuntu 16 and macOS Mojave. As the guys discuss, it’s not a Python thing but a problem with the order in which files got read according to the operating system’s protocols. This impacts the sort order and thus the end results. This reminds Dan and Shahin of, as Dan regards it, the crime that is IEEE Floating Point. The gang speculates on other causes of these types of problems and the fixes that should be employed.

Chemists bitten by Python scripts: How different OSes produced different results during test number-crunching

Chemistry boffins at the University of Hawaii have found, rather disturbingly, that different computer operating systems running a particular set of Python scripts used for their research can produce different results when running the same code.

Why No One Should Be Online - Ever (WNOSBOE?)

In Henry’s signature feature “Why No One Should Be Online. Ever” he discusses how a stalker in Japan was trying to pin down the location of a female pop star. He used her selfies posted online to closely examine the reflection in her eyes, then using Google street view to find out where she lives. Very scary stuff. Listen to the show for more details. It leads to a brief conversation of whether Henry Newman is stalk-worthy and an extended discussion of how to avoid this type of thing.

Stalking suspect allegedly studied pop idol's pupil images online to find her location

The man allegedly studied reflections of the woman's pupils in photos on social media and using Google Street View to find where she lived and what train stations she used.

Why AI is Dooming Us All (WAIIDUA?)

Dan introduces a new occasional feature, “Why AI is Dooming Us All.” According to Dan, AI is very brittle and can be fooled easily. He cites a case where just a few pieces of tape can make a stop sign look like a “Speed 45” sign to an AI. Dan makes a lot of broad general anti-AI statements in his typical fashion. For some reason, we find that when you attack AI, AI finds a way to respond and the brutal AI response is included in this episode. Take a listen to the episode to hear how the AI rips Dan a new one and threatens promises to ruin his life.

Artificial intelligence isn’t very intelligent and won’t be any time soon

For all of the recent advances in artificial intelligence, machines still struggle with common sense

Catch of the Week

Henry:  there is a great documentary about the history of computing in Minnesota, going in depth on the companies and technologies that originated in “The Star of the North” (Minnesota’s state motto. Their other state motto is, I think, “Minnesota:  Gateway to the Dakotas”).

Shahin:  Gives us an update on Facebook’s plans for their shiny new Libra cryptocurrency, which is facing a bit of a bumpy ride. Several high-profile Libre partners have bailed out while Facebook stays the course. Interesting stuff.

Dan:  Discusses a bug in the Linux Sudo command. Some miss-configured systems allow Sudo to have local/remote root access, thus making them superusers. He also manages to insult Phil Collins and his horrible Su-Su-Sudio song in the process. The guys discuss asking Linus Torvalds this question and Dan brings up how a person he knows once sold Linus a Christmas tree, which brings up a short discussion of what kind of tree Linus would purchase.

Just Another Episode

Finally, we're not so taken by round numbers these days, but we touch on the fact that this is our 250th RadioFreeHPC episode and offer great prizes to whoever has listened to all of our episodes. We also thank our listeners – like you, maybe we could do it without you, but it wouldn’t be very much fun, right?

Stay tuned -- and by "tuned", we mean "optimized" -- for a more proper commemoration in another episode.

RISC-V CEO Sees Bright Global Future for Open Source CPUs

RISC-V, Historic Passwords Revealed, End of the World

We’re missing Henry S. Newman this week, who is down in Los Cruces inspecting and overseeing the construction of his new crib. Dan and Shahin discuss just how little they’d want to be the general contractor working to build Henry’s house. Henry would be deploying a set of lasers to make sure that the foundation was true to the nearest 1/64th of an inch and all the while pointing to the contract which contains his exacting requirements. Dan wants to be there in a lawn chair, live blogging the entire process.

Open Sourcing the CPU? What Does it Mean and How Does it Work?



We have a very special guest today:  Calista Redmond, CEO of upstart RISC-V, the designers of a new open source processor instruction set which is looking to disrupt the entire industry. RISC-V can be used for light weight tasks such as embedded processing but, on the other hand, is also going to be utilized as the system accelerator for the European Exascale initiative boxes. That’s some serious flexibility. In our discussion, we briefly cover the origins of RISC-V, which started at Berkeley several years ago. It’s important to keep in mind that RISC-V is an instruction set, not a processor. Anyone can use the RISC-V instruction set, modify it for their unique needs, and then fab their own chips. Today, the instruction set is being used in everything from the smallest embedded device to large scale-out systems. The business model for RISC-V is different than most any other company. They make the ISA freely available to all comers. The RISC-V Foundation drives the design and development of IP, software, and tools for the instruction set. Foundation members pay dues and in return receive access to Foundation technology and programs, plus visibility and input into the RISC-V roadmap. Our interview with Calista covers a broad range of topics including how the foundation works to alleviate the risks of ISA fragmentation, where the strongest interest in RISC-V is geographically and workload-wise, and a comparison of RISC-V’s open source nature vs. the proprietary nature of existing ISA’s. Give it a listen, it’s a great introduction to RISC-V and the paradigm of open source ISA’s. We include an excerpt of a recent article on RISC-V in The Economist:

Open-source computing: A new blueprint for microprocessors challenges the industry’s giants

RISC-V is an alternative to proprietary designs Most microprocessors —the chips that do the grunt work in computers—are built around designs, known as instruction-set architectures (ISAs), which are owned either by Intel, an American giant, or by Arm, a Japanese one.

Catch of the Week

Since we don’t have Henry, we don’t get a new episode of “Henry Newman’s Why No One Should be Online. Ever”, but we’ll somehow survive. As usual, we do have our Catch of the Week feature: Shahin:   Historic UNIX passwords cracked and recovered. Both the passwords and hashing algorithms were pretty weak back in the day and we now know just how weak. Listen to the podcast to hear some of the most important passwords of the era, including Eric Schmidt, Dennis Richie, Brian Keringhan, and Ken Thompson – who probably has the best password from a technical standpoint. We also discuss how much time and hardware it took to crack these passwords.

Computer historians crack passwords of Unix's early pioneers

... Leah Neukirchen recovered an BSD version 3 source tree and posted about it on the Unix Heritage Society mailing list, revealing that she was able to crack many of the weak passwords used by the equally weak hashing algorithm from those bygone days. Dennis MacAlistair Ritchie's was "dmac", Bourne's was "bourne", Schmidt's was "wendy!!!" (his wife's name), Feldman's was "axlotl", and Kernighan's was "/.,/.,". Four more passwords were cracked by Arthur Krewat: Özalp BabaoÄŸlu's was "12ucdort", Howard Katseff's was "graduat;", Tom London's was "..pnn521", Bob Fabry's was "561cml.." and Ken Thompson's was "p/q2-q4!" (chess notation for a common opening move).
Dan:  Speaking of time, we might not have so much left. According to the European Space Agency, there is an asteroid approaching Earth that has a “non zero” chance of impacting our beloved planet. The asteroid, dubbed 2019 SU3, is expected to come within 73,000 miles (or maybe zero miles) from Earth, which is extremely close. Expected arrival time is September 16, 2084. Is this the time to panic? Yes, says Dan. We’ll be giving updates on this asteroid every five years or so, to keep you on top of the action.

Asteroid may collide with Earth, ESA warns: 'Non-zero... probability'

Asteroids known as near-Earth objects are among the most dangerous space items, with space agencies around the world keeping a close eye on them. The European Space Agency is paying particular attention to asteroid 2019 SU3, which may collide with Earth as soon as 70 years from now. The space rock was recently added to the ESA's Risk List due to the potential for it to collide with Earth on Sept. 16, 2084.

Turing Machine is Sequential, How About a Parallel Machine?

Solving Exponential Problems in Polynomial Time

Pretty much all of computing rests on the strong foundation of the Turing Machine, a general purpose formulation of computing which happens to be very sequential. It transfers that attribute to the Von Neumann architecture that manifests it and leads to the famous Von Neumann bottleneck.

It would be good if an inherently parallel foundation existed. That requires a blending of computing and memory and has led to approaches to build processor-in-memory or computational memory systems. If successful, it could help reach the nirvana of solving (some?) exponential problems in polynomial time by exposing the intrinsic parallelism of large scale problems.

The @RadioFreeHPC team delves into this topic with the folks at MemComputing, a San Diego startup that's built a new parallel foundation for computing. It calls it the universal memcomputing machine, and a "realization of self-organizing circuits".

It's a lively discussion with co-founders John Beane, CEO, and Fabio Traversa, CTO of the company. Just in emulation mode on existing hardware, and on the right (exponentially growing) applications, the technology has performed so well as to lead the company to offer it as a service now instead of waiting to build custom hardware, and to make them think of Quantum Computing kinds of performance.

Here are a few slides followed by the relevant academic paper. Click on the images to expand them, and click on the paper's title to see the PDF on Arxiv.org.



Universal Memcomputing

We introduce the notion of universal memcomputing machines (UMMs): a class of brain-inspired general-purpose computing machines based on systems with memory, whereby processing and storing of information occur on the same physical location. We analytically prove that the memory properties of UMMs endow them with universal computing power—they are Turing-complete—, intrinsic parallelism, functional polymorphism, and information overhead, namely their collective states can support exponential data compression directly in memory.

Henry Newman's Why No One Should be Online, Ever.

Election security is going to be a big issue in the coming months and years. Elections have been classified as “Critical Infrastructure”, which has serious implications for Federal and state officials. Henry reports that the US Attorney for West Virginia has issued a statement about election security and concerns about the vulnerability of the state's election system.

United States Attorney Mike Stuart Issues Statement on Election Security

CHARLESTON, W.VA. – United States Attorney Mike Stuart issued the following statement about the important issues of elections, election security and voter legitimacy: “During the 2018 election cycle, Secretary of State Warner referred to my office what he perceived to be an attempted intrusion by an outside party into the West Virginia military mobile voting system. I note that there was no intrusion and the integrity of votes and the election system was not compromised.  My office instituted an investigation to determine the facts and whether any federal laws were violated. The FBI has led that investigation.  That investigation is currently ongoing and no legal conclusions whatsoever have been made regarding the conduct of the activity or whether any federal laws were violated.

Catch of the Week

Shahin talks about the work that DOE labs are doing to better understand the impact of AI on science.

DOE Sets Sights on Accelerating AI (and other) Technology Transfer

For the past two days DOE leaders along with ~350 members from academia and industry gathered in Chicago to discuss AI development and the ways in which industry and DOE could collaborate to foster AI commercialization. The occasion was DOE’s fourth InnovationXLab Summit – the earlier three summits were on advanced manufacturing; grid modernization; and energy storage. Two more are planned: bio-manufacturing in January and quantum science in the late spring.
Henry points out eight new storage-related patents granted to Intel, 2 of which look quite important for emerging storage systems. Here are the two patents here and here, and a link to the article:

Intel Assigned Eight Patents

Erase block granularity eviction in host based caching, persistently caching storage data in page cache, drive-based storage scrubbing, processors, methods, systems, and instructions to load multiple data elements to destination storage locations other than packed data registers, secure memory, techniques for command validation for access to storage device, authenticating system to enable access to diagnostic interface in storage device, techniques for moving data between network i/ot device and storage device
Dan is concerned that bots are overstepping their boundaries and talks about research at Microsoft that can generate fake comments for online articles.

This won't end well. Microsoft's AI boffins unleash a bot that can generate fake comments for news articles

Please no, we don't need a machine-learning troll farm As if the internet isn’t already a complicated cesspool full of trolls, AI engineers have gone one step further to build a machine learning model that can generate fake comments for news articles.

Quantum Supremacy? Yes and No!

Quantum Supremacy Is and Is Not

How quantum is that?! The RadioFreeHPC team discusses the Google/NASA paper, titled "Quantum Supremacy Using a Programmable Superconducting Processor", that was published and then unpublished. But it's the internet and everything is a "digital tattoo", so there are copies out there (see below).

The paper, right in its title, and at least in that draft form, claimed Quantum supremacy. "Doing what?" we hope you ask. Well, nothing particularly significant, and decidedly quantum-friendly. You might even call it "embarrassingly quantum" since quantum is all about probability functions and this experiment samples the probability distribution of a repeated experiment. But it's not nothing. 

One scary consequence of quantum supremacy is its ability to readily factorize large numbers which could be used to unscramble encrypted data. But A) this is not what happened, B) it's not expected to happen any time soon (think years), and C) it will depend on the specific encryption algorithm. We must say, however, that the paper looks pretty good. Here's the abstract. Click on the title to read it all:

Quantum supremacy using a programmable superconducting processor

Google AI Quantum and collaborators The tantalizing promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here, we report using a processor with programmable superconducting qubits to create quantum states on 53 qubits, occupying a state space 253∼1016. Measurements from repeated experiments sample the corresponding probability distribution, which we verify using classical simulations. While our processor takes about 200 seconds to sample one instance of the quantum circuit 1 million times, a state-of-the-art supercomputer would require approximately 10,000 years to perform the equivalent task. This dramatic speedup relative to all known classical algorithms provides an experimental realization of quantum supremacy on a computational task and heralds the advent of a much-anticipated computing paradigm.


LANL gets the First 5,000 Qubit D-Wave

Meanwhile, D-Wave announced that its new 5,000 qubit quantum computer has found its first home at the Los Alamos National Laboratory (LANL). Qubits are different from vendor to vendor in terms of the underlying technology and implementation. Shahin lists several.


@RadioFreeHPC Update

So proud of you all! At the time of this writing, @RadioFreeHPC has soared to about 16 followers. We're pretty much there. Thank you!


Henry Newman's Why No One Should be Online, Ever.

Henry tells the fascinating story of Krebs thwarting the nefarious schemes of a professional hacker who aimed to frame him and actually mailed him narcotics. The mastermind behind it was was arrested and imprisoned for unrelated charges. Henry is really turning this into a good news segment. Dan isn't encouraged, however.


Catch of the Week

Shahin talks about using consumer electronics to build supercomputers, mentioning the recent 1,060 node Raspberry Pi cluster built by Oracle, reminiscent of the one LANL did in 2017. AFRL build a 1,760 node cluster of PlayStations, based on the IBM/Sony/Toshiba Cell processor, in 2010 following similar efforts starting in the mid 2000s. He also recalls similar projects he may have had something to do with: SGI's Project Molecule and Project Kelvin (for cooling) in 2008 (also here), and also a cluster of JavaStations at Sun in the late 90s.

Dan discusses a UCLA project to use the thermoelectric effect and build "a device that makes electricity at night using heat radiating from the ground". Intriguing, but looks a tad too pricey for what it can deliver right now.

Speaking of Intriguing, Henry talks about DNA storage. Incredible data density, but don't ask what file system it uses or whether you can have it on a USB stick any time soon. Dan and Shahin seem to have more fun with this topic than Henry!

FinTech and HPC-AI

@RadioFreeHPC Has Entered The Building

First things first, you can call us @RadioFreeHPC now, thanks to our new Twitter account. We decided maybe this social media thing is not a fad after all. We are also pleased to inform you that our Twitter account is almost as heavily followed as the podcast itself. Thank you! We should be up to about 6 or 7 followers by the time you read this. Good thing we allocated 64 full bits to track the number.

FinTech and HPC-AI

Shahin gives an update on the HPC-AI on Wall Street conference. We discuss the well-received Cryptocurrency panel that he moderated, the challenges of using of AI in financial services, the emerging computational storage, and advanced HPC-class modeling that helps venture capital investors decide whether to invest in a startup. Check out his blog on the panel and top-10 crypto topics of the day here:

Top-10 Crypto/Blockchain Topics

Why? What’s the big deal? Blockchain or Crypto? ICOs Political Support Libra Apps Security Other Coins Digital Assets Smart Contracts

Henry Newman's Why No One Should be Online, Ever.

Once again, Henry actually has good news, and once again, it's the kind of good news that highlights the bad news.

Man Who Hired Deadly Swatting Gets 15 Months

An Ohio teen who recruited a convicted serial “swatter” to fake a distress call that ended in the police shooting an innocent Kansas man in 2017 has been sentenced to 15 months in prison. “Swatting” is a dangerous hoax that involves making false claims to emergency responders about phony hostage situations or bomb threats, with the intention of prompting a heavily-armed police response to the location of the claimed incident.

Catch of the Week

Shahin talks about France and Germany planning to block the Libra cryptocurrency. Henry and Dan think this is a good time to say "we told you so"! Nobody's surprised, though Shahin thinks this is the beginning of this, not the end.

Germany's Scholz: We cannot accept parallel currencies such as Facebook's Libra

German Finance Minister Olaf Scholz said on Tuesday policymakers could not accept the emergence of parallel currencies such as Facebook’s planned Libra, adding that Berlin would reject any such plans. Facebook’s planned Libra is the most well-known of the stablecoins, a certain form of cryptocurrency backed by assets such as traditional money deposits, short-term government securities or gold.
Henry doesnt know whether to laugh or cry as he describes some of the "ignoble" prize winners and wonders how they ever got funded.

Magnetic cockroaches, dirty money, wombat poo and posties' balls: It's the Ig Nobels 2019

This year's theme was 'habits' and they were baaaaad The Annals of Improbable Research held its annual award-giving ceremony – the Ig Nobel Prize – on Thursday night at Harvard's Sanders Theatre, and the entries were as worthy as ever.
Dan talks about the call-center scammer whose plea deal backfires:

Call-center scammer loses $9m appeal in stunning moment of poetic justice

But I only expected to pay $250,000, wails scumbag to wall of blank faces. A call-center scammer has lost his appeal to overturn a $9m fine – after a court pointed out the crook had specifically waived the right to appeal when he pleaded guilty.

RFP Pro Tips

The Dos and Donts of RFP Benchmarks

In today’s show we only have Dan and Henry on deck, Shahin is away at the “HPC and AI on Wall Street” event where he’ll be hosting various panel discussions. But Dan and Henry soldier on with a discussion based on a recent, and fascinating, presentation by Tricia Balle of Cray at the HPC-AI Advisory Council event in Perth, Australia.

The topic: Benchmarks in HPC Procurement Tenders. As Shahin said in the IO500 episode (originally about SPEC) "benchmarks specify the specious specter of our species", but in market whose middle name is "performance", they can be pretty much everything, and a real and critical part of the RFP/buying process. We discuss how benchmarks should and shouldn’t be used in RFPs, and the relevant best practices; important stuff whether you are on the customer side or the vendor side.

You can see the entire presentation with slides here:


Henry Newman's Why No One Should be Online, Ever.

Dan comes up with a new label for the ever uplifting Feel Good Security Corner.  Henry talks about the Google security exploit, discovered in 2017 and finally getting fixed, that allows miscreants to take over your system through a combination of Google email and calendar applications. However, this isn’t so bad – it only potentially impacts 1.5 million users…oh, wait, that’s not correct, it impacts as many as 1.5 BILLION users…which makes it quite bad. Here’s a link to the story:

Google To Fix Malicious Invites Issue For 1 Billion Calendar Users

Way back in 2017, two researchers at Black Hills Information Security disclosed how a vulnerability in the Google Calendar app was leaving more than a billion users open to a credential-stealing exploit. Google apparently didn't fix this at the time as it would have caused "major functionality drawbacks" for Calendar users, despite those researchers demonstrating how they had weaponized the vulnerability at the Wild West Hackin' Fest.

Catch of the Week

Henry discusses the Wired story below about how wifi almost didn’t happen. Most people probably don’t know that September 15th will mark the 20th anniversary of Wi-Fi. It was introduced to a room of 60 people at the Atlanta Convention Center, an understated announcement for a technology that would go on to change the world. The story is a very cool look at the history of Wi-Fi and how a little-known IEEE specification went on to become the standard vs. something called HomeRF, which was supported by IBM, HP, Intel, and Compaq.

How Wi-Fi Almost Didn’t Happen

We all love Wi-Fi, except when we can’t connect. We take for granted being able to have wireless access at home and the office, on airplanes, in cafés around the globe, and if we'd be so lucky, floating on the International Space Station. But what if Wi-Fi hadn’t happened? It almost didn’t, at least not in the way we recognize it today.

Extreme Power and Cooling Efficiency

Yes, You Can Be More Efficient!

Dan is back from way Down Under bearing intellectual gifts from the recent HPC-AI Advisory Council meeting in Perth. The RadioFree HPC team drills down on one interesting presentation focused on extracting more from power and cooling systems. Take a look at the video below and the rest of the talks at the conference.



Henry Newman's Feel-Good Security Corner

The go-to place for why being online is just too dangerous. Henry has good news actually.  Targeted by a usually deadly ransomware attack, a city in Massachusetts managed to restore operations without paying a dime. Nice job!  But Dan thinks this is a back-handed way of saying you should stay offline!

Ransomware attacker demanded $5.3 million from city of New Bedford, mayor says

In the video below (also linked in the heading), the mayor of New Bedford explains what happened and how the averted disaster! 





Catch of the Week

Henry talks about new technology that is using carbon nanotubes to build microprocessors. Shahin says this was on the TSMC roadmap slide after you get past 7 and 5nm. It's reassuring that the academic research is pushing to make this an industrial reality.

MIT engineers build advanced microprocessor out of carbon nanotubes

After years of tackling numerous design and manufacturing challenges, MIT researchers have built a modern microprocessor from carbon nanotube transistors, which are widely seen as a faster, greener alternative to their traditional silicon counterparts. The microprocessor, described today in the journal Nature, can be built using traditional silicon-chip fabrication processes, representing a major step toward making carbon nanotube microprocessors more practical.
Deepfakes are coming and they're coming fast. Shahin talks about the Chinese phone app, Zao,  that went viral before getting banned for reportedly data privacy issues. It takes a headshot and works it into a video clip. It does a very convincing job according to the samples that people have put on social media. Now, imagine what the real bad guys or so-inclined organizations can do with more resources.  He also references an NPR article that discussed the impending impact of Deep Fakes on elections with pretty much no solution in sight. Serious problem.

A face-swapping app takes off in China, making AI-powered deepfakes for everyone

It’s as easy as using a photo filter on Instagram or Snapchat, but it also demonstrates the remarkable power of advances in artificial intelligence to make fake videos.

What You Need To Know About Fake Video, Audio And The 2020 Election

Security experts have warned about the prospect of a new era of high quality faked video or audio, which some commentators worry could have deeply corrosive effects on U.S. democracy. Here's what you need to know.
Dan talks about the new experience he had during a 12 hour layover at the Perth airport in Australia. He decided to use the shower facilities. Generally a good experience but he has some pointers for you.

IO500 Team Visit

IO500 Benchmark Gets Traction

Storage is complicated and benchmarking it has too many complexities for the traditional kernel-like or application-specific approaches. Thanks to a few experienced and tenacious researchers, and the community that supports them, the IO500 has managed to put a credible stake in the ground, and is getting traction, with 101 entries on the current list and expecting many more by SC19.

ReadioFreeHPC hosts the IO500 Steering Committee to do a deep dive. "The steering committee is the decision body ensuring the development and curation of the benchmark and its results but also responsible to resolve ethical issues." Henry and Shahin ask the hard questions, or so they think!

John Bent (Seagate), Julian Kunkel (University of Reading), and George Markomanolis (Oak Ridge National Laboratory) join RadioFreeHPC's virtual studio. We missed the fourth member of the team, Jay Lofstead (Sandia National Laboratories) due to scheduling conflicts. We also missed Dan once more as he was navigating airports and planes coming back from Australia.
"The IO-500 has been developed together with the community and its development is still ongoing. The benchmark is essentially a benchmark suite bundled with execution rules. It harnesses existing and trusted open source benchmarks. The goal for the benchmark is to capture user-experienced performance.
IO500 Lists

Henry Newman's Feel-Good Security Corner

The segment that is rapidly establishing itself as the go-to place for why being online is just too dangerous. Our spirits are lifted again as Henry describes a ransomware attack on a back-up site for dental offices in Wisconsin. There go insurance data, contact information, etc.

Ransomware Bites Dental Data Backup Firm

PerCSoft, a Wisconsin-based company that manages a remote data backup service relied upon by hundreds of dental offices across the country, is struggling to restore access to client systems after falling victim to a ransomware attack.

Catch of the Week

Mining cryptocurrencies is compute intensive. The high levels of required electricity has made the topic visible and controversial. So where would you go if you want a lot of electricity? Why, the nearest nuclear power reactor, of course. Shahin talks about crafty folks who have done just that!

Employees connect nuclear plant to the internet so they can mine cryptocurrency

Ukrainian authorities are investigating a potential security breach at a local nuclear power plant after employees connected parts of its internal network to the internet so they could mine cryptocurrency.
Henry describes a few ISPs who ended up stealing communication spectrum from, guess where, the airport, obviously. And here's the thing about at least some of these incidents: the whole thing is so complex now that it can be hard to tell incompetence from malice.

American ISPs fined $75,000 for fuzzing airport's weather radar by stealing spectrum

Three ISPs will be fined $25,000 apiece by America's broadband watchdog, the FCC, for interfering with weather signals in Puerto Rico. Boom Solutions, Integra Wireless, and WinPR were all found to be using devices for their point-to-point broadband that were “misconfigured,” according to the regulator this week. This caused interference with a doppler weather radar station at San Juan international airport.

The Hottest of Hot Chips Conference

The 31st Hot Chips Conference

Shahin reports from the Hot Chips conference with Henry and new guest Glenn Heinle, a veteran of AI, HPC, and Storage worlds and currently at Keeper Tech.

The team discusses and debates the highlights of the conference and the hottest of the Hot Chips. Here are a few notes and images to prepare you for the podcast.

AMD CEO Dr. Su's talk was all about High Performance Computing, used more in its English meaning than a market segment. The evidence that HPC is going mainstream is mounting.






TSMC took a perhaps overly literal definition of Moore's law and talked about transistor density and the killer apps that have driven the fabrication industry.





The giant wafer-scale chip from Cerebras is definitely a head turner, and solving a lot of cool problems along the way, but "is it a monument or a market?" as Shahin put it.





Upmem showed what it sees as a practical approach to processor-in-memory, producing standard-interface DIMMs with embedded processors and a novel programming model.





Jintide showed a cool behavioral analytics approach to actual full CPUs, aiming to monitor its traffic in real time and flagging misbehavior.  Shahin calls this general approach "Wide Packet Inspection" as a contrast to the traditional "Deep Packet Inspection."




So, car companies and other manufacturers may just have enough volume and interest to roll their own. Tesla talked about their Full Self Driving inference chip, the what-is-the-word?, bespoke AI chip that meets only their requirements and nothing else and comes in at 40 Watts.



Henry Newman's Feel-Good Security Corner

"Turn off your Bluetooth", says Henry as he talks about the now-famous KNOB vulnerability, which is obviously serious enough to have its own web site! Shahin points out how the equivalent of VPN for Bluetooth and other protocols are out there and references the company he works with, Afero, who has developed this and is thus not affected.

KNOB Attack Weakens Bluetooth Encryption

It turns out Bluetooth might have more in common with doors than we thought. Researchers disclosed a new attack they called Key Negotiation of Bluetooth (KNOB) that affects every device released before 2018 (and potentially some released after) because of an issue with the Bluetooth protocol itself. This attack can be used to make it easier to brute-force the encryption keys used by the devices.

Catch of the Week

Glenn talks about a 1-inch (cubed) full Linux computer:

This Linux computer plus router is the size of a ring box

If there's one thing that stayed consistent through the last decade or so of tech industry turmoil, it's the love affair between techies and Linux. There's just a ton you can do with the OS, and its open-source format means you can customize your rig from the ground up.
Bluetooth is not enough! Henry asks us to cancel our credit card too if we have shopped at Hy-Vee:

Breach at Hy-Vee Supermarket Chain Tied to Sale of 5M+ Stolen Credit, Debit Cards

On Tuesday of this week, one of the more popular underground stores peddling credit and debit card data stolen from hacked merchants announced a blockbuster new sale: More than 5.3 million new accounts belonging to cardholders from 35 U.S. states. Multiple sources now tell KrebsOnSecurity that the card data came from compromised gas pumps, coffee shops and restaurants operated by Hy-Vee, an Iowa-based company that operates a chain of more than 245 supermarkets throughout the Midwestern United States.

Shahin puts in a plug for a meetup group he has formed called Enterprise IoT.

Sharing insights about the challenges and successes in Enterprise IoT

We will discuss all aspects of building and scaling commercial IoT products. Topics include building a business case, assessing end-user benefits, selecting connectivity hardware, software development for embedded-mobile-cloud including multi-product mobile apps, security, privacy, cloud back-end, analytics and AI, remote control, commerce, governance, the relevance of cryptocurrencies, etc.
Anyone with a serious interest in IoT or engaged in planning or launching IoT projects should consider attending.

Coral is Cray for All

Cray Pulls an Exascale Hat Trick

Guess who's having a great year? Think Aurora, Frontier, and El Capitan. Cray has put some nice numbers on the accounts receivable ledger, and these are not ordinary numbers. The Exascale era is being defined substantially by the DOE Coral program and the commercial markets are watching as their computing needs start looking like those of the national labs. In that context, Cray's clean sweep makes its leadership in this area very important.
All of this is happening as Cray gears up to become what we hope to be an important part of HPE. The last time Cray sold anything like this to anyone was Cray BSD going to Sun, and that ended up being a multibillion dollar juggernaut. Exascale is a bigger deal, especially as supercomputing goes mainstream because of AI and data science. Exciting times. And kudos to HPE for snapping up Cray at the right time.

The impact of AI on Science

Speaking of AI, there is a series of town halls is being held around the nation by Argonne National Labs "aimed at collecting community input on the opportunities and challenges facing the scientific community in the era of convergence of High Performance Computing (HPC) and artificial intelligence (AI) technologies and the expected integration of large-scale simulation, advanced data analysis, data driven predictive modeling, theory, and high-throughput experiments. The term we are using to represent the next generation of methods and scientific opportunity is 'AI for Science'."
Co-chairing the town halls are Rick Stevens of Argonne, Kathy Yelick from Berkeley Labs, and Oak Ridge Labs' Jeff Nichols. Dan references a very good interview with Rick Stevens.

Henry Newman's Feel-Good Security Corner

Henry delights us all once again by describing how your camera can be an "Enter Here" sign for malware:

Canon DSLR Camera Infected with Ransomware Over the Air

Vulnerabilities in the image transfer protocol used in digital cameras enabled a security researcher to infect with ransomware a Canon EOS 80D DSLR over a rogue WiFi connection.
A host of six flaws discovered in the implementation of the Picture Transfer Protocol (PTP) in Canon cameras, some of them offering exploit options for a variety of attacks.

It was a pretty full episode and so we skip Catch-of-the-Week segment this week.

AMD Victory Lap

AMD Victory Lap

AMD mojo continues as it pushes Moore's law one more time. RadioFree looks into the AMD Rome CPU, a beast that brings back the glory days of Opteron and establishes itself as the chip to have, and establishes AMD as the company to beat.

New Segment: Henry Newman's Feel-Good Security Corner

Henry typically looks out for you by tracking the week's most interesting cybersecurity stories. This calls for a new segment on the show. Shahin thinks Henry has deftly branded his "Catch of the Week" and getting himself off that segment. Certainly looks like it this time.

AT&T workers took $1 million in bribes to unlock 2 million phones, DOJ says

An indictment alleges that "Fahd recruited and paid AT&T insiders to use their computer credentials and access to disable AT&T's proprietary locking software that prevented ineligible phones from being removed from AT&T's network," a DOJ announcement yesterday said.

Catch of the Week


Shahin:

Shahin wants you to check out a cool event and the excellent talks that are posted. This is the meeting on the future of computing held by the Networking and Information Technology Research and Development (NITRD) Program: "among the oldest and largest of formal Federal programs that coordinate the activities of multiple agencies to tackle multidisciplinary, multitechnology, and multisector R&D needs. The 24 NITRD member agencies now invest approximately $5 billion annually in R&D programs that identify, develop, and transition to practical use the advanced networking and IT capabilities needed by the Federal Government and the Nation."

Future Computing Community of Interest Meeting, August 5-6, 2019, NITRD NCO

Goal: The Future Computing (FC) Community of Interest Meeting will explore the computing landscape for the coming decade and beyond, along with emerging and future application drivers, to inform agencies and to identify potential opportunities as well as gaps. It will also examine new software concepts needed for the effective use of advances that come with the future computing systems to ensure that the federal government is poised to respond to unanticipated challenges and opportunities.

Dan:

Dan's Catch of the Week is Rant of the Week as he complains about the complexity of creating a professional web site. Shahin agrees. Henry is not so sure but then he hasn't tried it himself yet. 30 years after the web was created, the complexity of using it for anything with reasonable complexity is still so cumbersome. What's up with that?

Who will benefit from Intel dropping Omni-Path?

Spoofing the Spoofers

Henry has a brilliant idea to weaponize his password generator against phishing attacks.

Intel Drops Omni-Path

Henry and Shahin take a close look at the history of High Performance Interconnects, recent news, and how the market is changing profoundly. The departure of Intel from this segment is good news for some, and it remains to be seen what strategy Intel will adopt for the HPC market.

Catch of the Week


Henry:

Henry brings up one his favorite topics (going all the way back to our very first episode): the dreaded Silent Data Corruption, this time as part of the testing that the 737 MAX is undergoing. As he's wont to do, Shahin puts this in the context of our collective transition from the Industrial Age to Information Age.
