crb002··on The Infosec Apocalypse
Blind SAST will give many false positives. It took a local megacorp a year to reduce noise on their Java build pipeline when adopting it.
crb002··on Moving 25TB data from one S3 bucket to another took 7 engineers and 2 full days
They have Snowball for this, up to 50 TB. https://aws.amazon.com/getting-started/projects/migrate-peta...

Also, throwing a swarm of lambdas to chunk the files into about 250mb temporary zip files would help.

crb002··on Nvidia reportedly to acquire ARM Holdings from SoftBank for $40B
What if NVIDIA then turns around and offers to sell to TSMC and everybody is screwed?
crb002··on Physics is stuck
We need a research satellite around Mars to better understand long range forces. The immediate problem is being bound to Earth distance experiments, including astronomy from two long range reference points. Also need a Venus or Sol orbit solar satellite with a massive capacitor on it for doing obscenely high power experiments.
crb002··on GitHub Won’t Help You with Hiring
It could if you were smart about it. See the scripts at:

https://github.com/adamtornhill/code-maat

You could identify high quality devs that are suddenly funemployed with a burst of github activity - and reach out to them in a non-sleazy manner.

crb002··on Jensen Huang’s vision for data center dominance may destroy the Arm ecosystem
HDMI firmware overhead can be amortized, but the wasted space is huge - racks should be designed to hook up with HVAC/Power/Network - not so techs can plug in monitors.
crb002··on Jensen Huang’s vision for data center dominance may destroy the Arm ecosystem
I almost guarantee the delay in the build out of their Waukee Iowa data center is so they can fill racks with server grade Apple Silicon.
crb002··on Jensen Huang’s vision for data center dominance may destroy the Arm ecosystem
https://oxide.computer/ has a simple mission. Build hyperscale racks with open firmware/drivers - cut the wasted components like HDMI ports that Dell/HP still throw on racks by default. ARM/RISCV/x86/GPU/TPU/storage ... those are just configuration options.

Companies like Lightedge will take on the HVAC and physical security. The future is chiplets and computational memory: https://www.researchgate.net/profile/Michael_Stumm/publicati...

crb002··on Automotive Grade Linux
Many manufactures use the Intel Windriver distro of Yocto. SQLite3 is king just like on a mobile phone. Dbus/Qt for GUI applications. Froglogic Squish is a PITA https://www.froglogic.com/squish/editions/qt-gui-test-automa... - need an open source alternative.

Test builds should have ksan/asan turned on by default.

Production builds should ruthlessly remove unused binaries and make heavy use of --gc-sections to cull dead code. Even SQLITE3 should have features whitelisted to make it more safe.

Several TLA+ and Alloy specs need to be written to ensure distro saftey.

crb002··on AutoCXX: Safely call C++ from Rust with auto generated bindings
Why not wrap for use with dlopen()?
crb002··on Build tools around workflows, not workflows around tools
The humble .plan file. https://github.com/ESWAT/john-carmack-plan-archive
crb002··on Citibank's $900M Blunder
"Revlon was expected to transfer a few million dollars to some of its lenders." - Brigade was owed money, and while Brigade must return funds in excess of the loan, it can't be forced to reloan the money - Citgroup would have to cure by pulling out their own checkbook to loan Revlon.
crb002··on Factorio and Software Engineering
It teaches the importance of latency in design.
crb002··on Hiding messages in x86 binaries using semantic duals
You could do stenography with ordering of function/data sections VS an expected permutation.
crb002··on Dashboard for tracking insider trading at S&P 500 companies
I don't trust this. I want to see cancellation of scheduled trades. I.e. Bezos/Cook not divesting shares on schedule all of a sudden.
crb002··on What's wrong with Intel, and how to fix it: Former principal engineer unloads
Except AWS and Apple can and do recompile the ocean, even over to ARM. AVX512 free chips and gutting legacy X86 are worth it, perhaps an x86_64_2020 target?
crb002··on You don’t need reproducible builds
Define reproducible. I always archive dependencies so I can rebuild, even if that build has some new timestamps in it. Having a rando Github repo go down when you rebuild is not a failure mode I want.
crb002··on TikTok’s Chinese owner offers to forego stake to clinch U.S. deal – sources
If they get paid in MS stock with a little cash that's probably the best exit they could hope for. Hopefully MS doesn't kill it off like Skype - which should have been Zoom.
crb002··on The Haskell Elephant in the Room
Does Haskell have a legible GC free subset that is an alternative to Rust? If not, that is the elephant.
crb002··on Porting a macOS Clojure Dev Setup to Windows WSL2
My notes. Many yaks were shaved due to Windows hating my graphics card. https://github.com/chadbrewbaker/CompilingOnAWSLambda/blob/m...
crb002··on Doctor advises only using soap on your hands and nowhere else
A wet loofah will exfoliate just fine without soap. You don't give your colon a soap enema every day, why do that to your skin microbiome?
crb002··on We Need a Yelp for Doctoral Programs
The last time I tried to interact with Iowa State University ECprE, a professor who I won't name asked me for a $20,000 bribe to do research with their lab. Confirmed their culture is just as toxic as it was a decade ago.
crb002··on The Billionaire Behind Efforts to Kill the U.S. Postal Service [pdf]
The US Postal Service should be funded like NASA. It can contract out to companies like Amazon - just like NASA contracts to SpaceX.
crb002··on The FBI is secretly using Sabre as a global travel surveillance tool
The FBI is probably using all information sold to advertisers. The EU passed GDPR for security, not just privacy.
crb002··on Microsoft Analyzed Data on Its Newly Remote Workforce
There might have been noise elimination. Less useless meetings. Quality != quantity.
crb002··on Show HN: Dockerfiler: declarative management of images built from Dockerfiles
Perhaps mount an external directory and extract all artifacts to it as a zipfile at the end of the build.

crb002··on Show HN: Dockerfiler: declarative management of images built from Dockerfiles
Also, Docker should have a reproducible flag that creates binary reproducible images. Timestamps and local system info would have to be nerfed to some default or fed in statically with a config file.
crb002··on Show HN: Dockerfiler: declarative management of images built from Dockerfiles
Maybe I am stupid, but is there a problem in Docker build design? By default you should get both a Docker image and an artifacts.zip of binaries that it downloaded so you can pin them? The cache isn't just for speed. It allows for reproducible builds.
crb002··on Could IPOs be replaced by blank check acquisitions (SPAC)?
Seems less burdensome to find a large publicly traded company willing to invest with shares of their non-volatile stock. Say megacorp buys a 30% stake, then vested employees get a distribution of 30% of their vest as megacorp stock. You might call this IPO Lite. Benefits of market liquidity for all the shareholders and retain the limited dilution of an IPO.
crb002··on Coursera valued at $2.5B after a finance round of additional $130M
Not a huge fan of ads, but I would accept non-obtrusive ads in lieu of paying the certification fee if they wanted a traditional publisher revenue stream.
