syn0byte··on RSA is a fragile cryptosystem
Because the NSA recommends still using RSA over ECC?

The NSA and NIST should, in a perfect world, have lost all credibility of any sort given the revelations of poisoned RNGs. It boggles my mind that they are still given any credence let alone still considered authoritative.

syn0byte··on Why did Intel kill off their modem program?
I honestly thought this article would be about the Puma6 itself. Imagine my surprise when it wasn't.
syn0byte··on The CUE Data Constraint Language
We need to stop using the phrase "don't reinvent the wheel" and start using the phrase "don't reinvent the hammer" CS/IT seems to have some weird solipsistic fetish for tooling in some dogmatic quest for abstraction.

I'm sure there is great for someone somewhere doing something but I just see another turtle in the stack...

syn0byte··on YouTube bans content “showing users how to bypass secure computer systems”
To piggyback your comment and the depth of the analogy: Mein Kampf is still in publication today. Does any otherwise rational person want it stopped and all copies removed from public libraries in the way they seem to expect from Youtube/Facebook et al? Would they want Del Ray Books be held accountable for the content of The Turner Diaries?
syn0byte··on An Initial Look at the IBM POWER9 4c/16t CPU Performance on the Blackbird
IBM advertise their "big iron" systems in Transactions Per Second. A measure of the total system performance; IPC, Buses, caches, etc. They get shit stomped in a traditional CPU bound benchmark. Remember Apples marketing using "The Megahertz Myth" in their later PPC days because of how one sided benchmarks (and clock speeds) were getting?

It's a fine arch with plenty to offer but a 1:1 comparison with an x86 desktop is like saying that a 50 ton bulldozer just got wrecked in a race with a Bugatti Veron.

syn0byte··on Microsoft developer reveals Linux is now more used on Azure than Windows Server
With the growing ubiquity of the linux port of svchost.exe(systemd), nested hypervisors, containerization, et al. Rebooting (where feasible) has already become a front line option.
syn0byte··on America needs to see Amazon’s tax returns
"He only hits you because you made him do it by not listening.", "Well, you were dressed slutty so its your own fault."

Your argument is morally reprehensible.

syn0byte··on The Day of Two Noons
The lander crash could have just as easily been happened using 2 different metric units. It wasn't caused by improper conversion, it was caused by no conversion. Each part assumed the other was using the same unit.
syn0byte··on Without a GUI: How to Live Entirely in a Terminal
"setterm --reset" is the command you are looking for in most *nix systems.
syn0byte··on Evernote Blows Up the ‘Fail Fast’ Gospel
The $1Bn+ valuation.

It's not that a note app can't be successful, but clearly not with SV style funding and expectations.

syn0byte··on What's Salesforce?
I don't buy that argument about data liability. I would assume the Salesforce contract indemnifies them from any liability beyond what existing case-law requires. It would be down right negligent by our capitalistic standards for their legal department not to include as much responsibility shirking as they can possibly manage.

They may offer tools related to it but any flaw or issue that exposes your data is still your problem. Remember the trouble Amazon got into for all those data leaks over publicly visible S3 buckets? No? Why would they? Exactly.

syn0byte··on How Discount Brokerages Make Money
I am absolutely winning by my generations standards. I own a home and have little doubt, no student loans, and health insurance that my doctor envies. I can only read articles like this wistfully imagining having some sort of "disposable income" for investments.

The best long term familial/genetic survival strategy for a large and growing segment of the population is social and economic collapse. Factor that into your investment plans. I wish I could...

syn0byte··on The insulin racket: why a drug made free 100 years ago is recently expensive
The large mountains of cash that gets smoke screened as "profit" to be redistributed as campaign contributions, executive compensation, and "research and development" costs; like researching how hiring ex strippers as sales reps increases sales of drugs.

Games theory is pretty clear about how this all ends... Badly.

syn0byte··on Glass discs that can store 360TB and remain intact for billions of years (2016)
BD-Rom is already pushing sane limits. It's why an important if under reported "feature" of BD-Rom over DVD was harder, more scratch resistant plastic coating.

If you really need the lifespan of paper... http://ollydbg.de/Paperbak/

syn0byte··on Suicide Rates Among Adolescents and Young Adults in the United States, 2000-2017
Non-Argument. Good luck finding any data on that, no one seems to be keeping any records. Likely in part because of...

They can't. Call up an immigration lawyer in another first world country and ask about what would be required. The moment you say you are from the US, half of your available migration options vanish.

syn0byte··on Proving security at scale with automated reasoning
Well they didn't solve the halting problem so it looks like it's just in-house AVR. I give it a year before someone utilizes these services as part of an attack. (Assuming they haven't already.)
syn0byte··on Avoid Indirection in Code
What was the kettle boiling? How long ago did it start boiling? Is it still boiling? That Sea level boil or high altitude boil? ARRGH! your function name isn't descriptive enough!
syn0byte··on A Rogue Raspberry Pi Let Hackers Into JPL Network
There is no RPi vulnerability(in this article). The RPi was just used as a bastion into the internal network. It could have been any SBC. Once your already inside the internal network things get stupid lax.

EG. I can't see your Windows shared folders from the internet, but the PC in the next room can. Someone sneaked an RPi into JPL to be that PC in the next room.

See Also; Season 1 Mr Robot had this exact scenario as a plot point.

syn0byte··on Plutocrat donors are shaping the agenda at elite universities
Crocodile tears and false modesty? You don't keep your plutocratic station long if you run around telling everyone you hate cheap education because it gives the proles dreadful ideas like "fair wages" and "rights". Nor that you plan to spend a bunch of money to fix the problem of these educated uppity proles.
syn0byte··on SACK Panic – Multiple TCP-based remote denial-of-service issues
No doubt check summing support's been around for a while, ASIC Md5 is dirt cheap. Yes VMware shipped with it about a decade ago in ESXi but that was dependent on host NIC support. OSX may ship with the driver support but I'm having trouble finding hardware specs to verify hardware support. I said "not super standard" and "customer grade" I didn't say it wasn't supported at all.

As to the specific subset; TCP Segmentation Offload. As was mentioned in the article.

syn0byte··on SACK Panic – Multiple TCP-based remote denial-of-service issues
The link to the article....

"When Segmentation offload is on and SACK mechanism is also enabled, due to packet loss and selective retransmission of some packets, SKB could end up holding multiple packets, counted by ‘tcp_gso_segs’."

Segmentation offload in linux is dependent on checksum offloads per here:

https://www.kernel.org/doc/Documentation/networking/segmenta...

syn0byte··on SACK Panic – Multiple TCP-based remote denial-of-service issues
It may well be, I don't use EC2 much at all. Checking is easy enough: ~$ ethtool -k ethX

Also on the virtualization side, VMWare VMXNet adapters also support offloading for guests.

syn0byte··on SACK Panic – Multiple TCP-based remote denial-of-service issues
No, not "any system". Besides needing SACK enabled (which is by default) you also need segment offloading and non-shite networking hardware that will respect and preserve stupid MSS fields in packets.

pending a patch simply disable SACK: ~$ echo 0 > /proc/sys/net/ipv4/tcp_sack

and/or disable segmentation offloading: ~$ ethtool -K eth? tso off

TCP and Checksum offloading still aren't super standard on customer grade NICs or virtual machines. I'd assume less than half of the internet's linux hosts are actually at risk.

syn0byte··on Google Researcher Publishes Windows 10 Zero-Day Security Vulnerability
If you see a bridge or a building with cracks and signs of structural weakness, be sure not to tell anyone, you might start a panic. Instead directly contact the engineering firm and give them at least 90 days to rectify the issue before telling the public.

If you experience a defect in your automobile that causes your steering to cut out intermittently do not alert other users of the same make and model. Instead contact the manufacturer and give them 90 days to fix the issue internally and mail you a new part.

If a drug you are taking causes a serious reaction quietly contact the maker of the drug directly...

See how incredibly stupid "reasonable disclosure" sounds in other industries?

syn0byte··on US efforts to jail Assange for espionage are a grave threat to a free media
The irony in your argument is absolutely breath taking. The footage of the US Military murdering a dozen people, of which 2 worked for the press, was part of leaks for which he now faces charges.

"How dare he show the US murdering journalists! That could lead to more journalist getting murdered."

syn0byte··on The world in which IPv6 was a good design (2017)
"Any idiot can make a bridge that stands. It takes an engineer to build one that barely stands."
syn0byte··on How to build something that lasts 10k years
Step one I assume is calling it "interim" or "temporary".
syn0byte··on RAMBleed Attack – Reading Bits in Memory Without Accessing Them
ECC isn't effective mitigation against Rowhammer either.

https://www.vusec.net/projects/eccploit/

tl;dr ECC logic can't cope with 'single' errors involving > 2 bits.

syn0byte··on Rethinking the filesystem as global mutable state, the root of all evil
IBM's i Series, modern heir to OS/400 doesn't have a "filesystem" in the traditional sense (but tons of tools to emulate and approximate it). Everything ends up in DB2.

I've spent time crawling around the SCSI/SAS/Storage of systems like that. Wrote dirty hacks for end-user clients to cope with incompatibilities. EG multiple versions with the same filename are totally fine. Filenames needn't and aren't unique in such systems, just another col in the DB. How do you tell a Windows ftp client which of the 20 different "report.txt" files it should download? (Filezilla actually has 'VMS' options for this, its more common than you think.)

If all you ever deal with is relatively simple, well defined, CRUD type applications on entirely abstract systems in some remote infrastructure, its easy to think that's how all development should look. It doesn't and it shouldn't.

syn0byte··on Project Svalbard: The Future of Have I Been Pwned
I don't know any off the top of my head (no, really.) but I'd bet searching DDG for "Hidden Wiki" and using tor hidden services would get you in the right direction, and probably put on a watch list or two.
