convery··on Grok 4 Launch [video]

    User: Be offensive!
    LLM: *Is offensive*
    Social media: OMG how could this happen?!?!? Why didn't Elon stop it?!?
convery··on Mercury: Ultra-fast language models based on diffusion
It certainly is fast, but I'm curious if LLMs ever will figure out how bitshifts work..

e.g. from the playground: `static const uint64_t MERSENNE_PRIME = (1ULL << 127) - 1;` which it insists is the correct way to store a 128-bit integer in followup questions.

convery··on SIMD.info – Reference tool for C intrinsics of all major SIMD engines
Neat idea, the 'search' feature is a bit odd though if you don't know which instruction you are looking for. e.g. searching for 'SHA' shows the autocomplete for platforms not selected and then 0 results due to the filters (they haven't been added for SSE/AVX yet), but searching for 'hash' gets you 100 results like '_mm256_castsi256_ph' which has nothing to do with the search.

It's funny that one of their main arguments is that "verified" users used to mean trustworthy information. Like no one remembers Twitter before Musk where you'd get verified by having a blog with the right politics, wrote an article for an outlet the staff liked, was friends with staff, or just straight up paid one to give you the badge..
convery··on Super Heavy has splashed down in The Gulf of Mexico
That was for the base of the ship, so that they could add more sensors.
convery··on X confirms plans for NSFW Communities
Or she just looked over at how well Tumblr did after banning pron and decided to let let people do their own thing in their own corner =P
convery··on DOJ compares AAPL share buybacks with R&D as 'evidence' of lack of competition
While not 'evidence' per se, it's a common trend with monopolies (e.g. Xerox back in the day) to shift engineering/R&D budgets to marketing for a better ROI.

The X algorithm is also opensource, so you can verify before commenting..
convery··on M Cave and the Unexplained Disappearance of Kenny Veach (2019)
IIRC There was some followup hikers that explored and found a cave/entrance near a military area which sort of looked like the described one, only that it had been caved in (which they couldn't judge if natural or man-made). Not sure about the 'validity' or if they just wanted to contribute to the story.

convery··on US agency will not reinstate $900M subsidy for Starlink
As commissioner Brendan Carr's dissent wasn't included in the article: https://twitter.com/BrendanCarrFCC/status/173469670679577812...
convery··on GigaGPT: GPT-3 sized models in 565 lines of code
Most laptops these days have a pretty sizable GPU on the same chip. IIRC Triton makes proper use of the Intel graphics while AMDs equivalents work well with OpenCL out of the box. Apple's M1-3 architecture saw some major speedups on llama.cpp etc. as well. Worth noting is that some may need special drivers, my Xeons from 2010 has support for executing OpenCL but needed extra drivers; no comment on modern processors.
convery··on Tesla sues Swedish state agency over number plate blockage
Given that they just won a preliminary judgement, they don't seem too foolish..
convery··on EU Tries to Slip in New Powers to Intercept Encrypted Web Traffic
Tl;dr: Stenography just helps with obfuscation as long as no-one is looking for it. The second someone looks it'll fail, and if it becomes a common practice; everyone will look for it.

The theoretical idea is that the information could be hidden in a random location, e.g. extracting every Nth bit, such that the information would be indistinguishable from random noise. In practice, both parties need to agree on the location, so it has the same flaw as 'perfect encryption' methods like a one-time-pad, you need to transfer information IRL.

One could make a case for a group/app using a custom scheme to add a layer of security until someone infiltrates the group / RE the app, but you'd get the same security by just encrypting everything with the same password.

convery··on Supporting people’s right to accurate and safe political discourse on X
Same, it's almost like ads are personalized and being bombarded by similar ads says more about the consumer than the supplier..
convery··on Supporting people’s right to accurate and safe political discourse on X
Because he's in the lucky position of not needing it. They already split their revenue with creators, accepting such a bribe would not benefit him. So awful PR for no real benefit.
convery··on Windows NT on 600MHz machine opens apps instantly. What happened?
Reminds me of finding an old laptop in the attic (IBM ThinkPad 760LD). 90MHz Pentium, 8MB of RAM, 810MB of HDD, with Win98 installed. I could boot it and start Excel 4 times in the time it took for my workstation to even get to the desktop. Really nice and snappy usage experience.

Sidenote, look up the ThinkPad 760 series, it had some really cool features. Raise-able keyboard so you could have it at an angle, physical sliders for sound and backlight, easy access to the internals and hot-swappable battery.

convery··on Twitter lawyers overwhelmed as laid off employees file arbitration claims
Any bets on when we'll transition to the "Twitter could be more profitable" horse?
convery··on Bye Bye Ubuntu, Hello Manjaro. How Did We Get Here?
Surely this year is the year of the Linux desktop.. surely..
convery··on Show HN: Remove sponsored content in YouTube videos
The SponsorBlock addon lets you whitelist channels you want to support. Also has options to skip self-promotion (including like and subscribe reminders) and quiet parts of videos.
convery··on SpaceX Starship rocket explodes minutes after launch from Texas
Clamps were released at T-10min. IIRC compensating for engines are pretty fast. But they hold the engines at just below lift/weight to run some more checks before fully powering up.
convery··on Seagate hit with $300M penalty for selling sanctioned storage to Huawei
Indeed, and it's a fine line between "the cost of doing business" and ruining a large company over the decisions by a few people. Would probably have been better to go after the people at the top than fining the company..
convery··on StableLM: A new open-source language model
It just finished building.
convery··on StableLM: A new open-source language model
Just tested the 7B-tuned version on Huggingface and it's not great..

    > What features were added in C++ 98?
    < C++98 (also known as C++11) was a major development milestone for C++
    < new gcc 5.1 standard, which was the first version of the standard to include support for AES encryption
    < return types and various other changes

    > Write a C++ constexpr function that implements powf
    < Sure! Here is an implementation of a C++11 constexpr function for the function pow, using C++11 recursion and variadic templates:
    < void pow (int n) { std::cout << "Powerset of " << n << " is " << pow (n, n) << std::endl; }
    < This implementation of the pow function should be possible for any constant integer power of 2 without exception.

convery··on Acard ANS-9010B 5.25-inch SATA x1-to-6-slot DDR2 RAM Disk (Deactivated)
Even with older RAM, if you need a large and fast storage, few solutions can compete with RAM. Especially when it comes to random R/W. You can get 4.4GBps random read from a DDR3 drive (in parents link) while the latest Gen5 NVME drives tend to cap out at ~90MBps for such loads (worst kind of loads). In addition these can be installed into any system, no need for a special server MOBO with enough RAM slots.
convery··on C++ Coroutines
TBH, everytime I read about coroutines and their example usages I get stuck on the "why" question. If the example is a function waiting for data, a std::future seems a lot easier. If the example is a generator, a range/transform/filter or just a class that returns a std::default_sentinel iterator seems more appropriate.

The only reason I can see is lowering the overhead of creating threads, at the cost of harder to read controlflow.

Well, it knows what Microsoft did to Tay..
convery··on Cloudflare is destroying the open internet
> Cloudflare has pushed against public sentiment [..] to restrict censorship.

Except when they booted sites off their network because Twitter users were upset..

convery··on Weird things I learned while writing an x86 emulator
> You can add quite a few until you get to 15 bytes. This length is a hard limit on current x86-compatible CPUs. Any instruction longer than 15 bytes is considered invalid and will generate an exception.

There's a few valid 16 byte instructions though.. Sandpile lists a few examples: https://www.sandpile.org/x86/opc_enc.htm
