WallWextra··on Durable execution should be lightweight
Racket's web framework has a feature to serialize continuations and restore them, which I instantly thought of the first time I saw durable execution.
WallWextra··on Users say T-Mobile must pay for killing "lifetime" price lock
Are you not satisfied by boots which lasted 20 years?
WallWextra··on Ask HN: Who has moved from the U.S. to Europe?
If you're not lucky enough to be among the privileged, moving to Europe is impossible unless you have inherited citizenship (which is itself another kind of privilege).
WallWextra··on Ask HN: Who has moved from the U.S. to Europe?
I recently moved from the US to Berlin. I plan to return to the US.

Pros of Berlin:

- Good transport

- Bikeable

- Safe

- Cheaper than the big coastal cities in the US, with lower rent.

- Good clubbing (not my thing)

Cons of Berlin:

- Healthcare is inconvenient. Doctor's offices won't pick up the phone, and won't leave you on hold. You just have to go in person. Providers all work in small doctor-owned practices, and you get a referral runaround with huge wait times.

- The food in Germany is terrible. The quality of produce and other ingredients is very bad, and the restaurants are nothing special. One notable bright spot is the availability of vegetarian and vegan food. Also falafel and doner.

- The salaries are shockingly low. Really ask yourself if all the comforts of Europe are worth cutting your salary in 2 or 3, and that's before...

- Taxes. The top tax rate here is in the low-40s, comparable to the US, but unlike the US, the top tax bracket starts below $65k.

- Europe has an impending demographic crisis, and the social safety net they fund by plundering your paycheck probably won't be there for you when you retire.

- Stores in general suck. They have fewer, and worse products.

- Everyone still smokes here.

WallWextra··on What’s Wrong with “Multiplication Is Repeated Addition”? (2008)
If you define the reals axiomatically, you still need an existence proof. Which will involve addition and multiplication algorithms.
WallWextra··on Half Doses of Moderna Vaccine Produce Neutralizing Antibodies
There aren't many people with the expertise to produce the vaccine, and they're all already working on the existing production lines. The lead times are just inherently long here; takes months to start up a production line.
WallWextra··on Who wants to live for ever? Ageing can be cured–and, in part, it soon will be
Sounds no worse than people dying, and their children inheriting their assets with a stepped-up cost basis.
WallWextra··on Web Programming with Continuations (2002) [pdf]
The racket web framework has an option to serialize the entire continuation for he client to send back to you. Pretty intense.
WallWextra··on YTMND is down for temporary maintenance
dril was doxed a couple of years ago. You can google around for his real name, which is not Richard Kyanka.
WallWextra··on Ask HN: Do you like/use Reddit's redesign?
I would like it quite a lot if it worked properly, but there are some pretty brutal bugs. I have some amount of faith that they'll be fixed, though.
WallWextra··on Ginseng: Keeping secrets in registers when you distrust the operating system
More architected (i.e. program-visible) registers require more bits to encode.
WallWextra··on Ginseng: Keeping secrets in registers when you distrust the operating system
Wouldn't you need, in addition to patching the interrupt vector, to make sure there is no existing code running in the kernel when you restore the sensitive registers? This makes the nginx use case seem kind of unrealistic.
WallWextra··on Symbolics Lisp: Using the DEC Alpha as a Programmable Micro-Engine (1993) [pdf]
The most pleasant thing about this is how the lisp machine's instruction set turned out to be a good bytecode for interpretation. Calling it "microcode" seems risible today, but I don't know if it was as ridiculous in 1993.
WallWextra··on How Big Tech Built the Iron Cage
I agree. At the very least, there should be some dialogue on whether the trade off is worth it. I lean towards yes, most people think we can get the privacy back without giving up the advantages. I'm not sure how, but I'd be interested.
WallWextra··on Nobody wants to read your shit (2009)
Journalists seem to think they're practicing literature. I don't know where they got that idea.
WallWextra··on Rust is not a good C replacement
You don't have to care about memory safety, but if you don't you probably shouldn't speak for "systems programmers" as a whole. Systems need to be safe.
WallWextra··on Google's Work with China Eroding US Military Advantage, Dunford Says
The smaller companies would have even less inclined to ignore a market of a billion people.
WallWextra··on Curing the Vulnerable Parser: Design Patterns for Secure Input Handling (2017) [pdf]
I am betraying my ignorance with this question, but: On the last page, the authors claim that SQL queries are commonly constructed by concatenating strings. Was this still, in fact, common in 2017? If it was, that's very scary.
WallWextra··on The corrosive culture of modern work
Tesla is barely profitable. Bob's red mill is filling a tiny niche. The price of a yacht wouldn't pay that many people's wages either.
WallWextra··on Pale Moon Browser Continues Support and Development of XUL
It wouldn't be worth dealing with these people even if they were developing a good technology, but XUL???
WallWextra··on Graying Out
The macOS messages app fills a lot of this void for me, if you have an iPhone.
WallWextra··on New fastest portable hash: wyhash
Most of his arguments simply do not apply to the relevant use case and attacks. The only one that does, the claim that the seed is recoverable, is not an argument at all but a vague, unsubstantiated claim.
WallWextra··on New fastest portable hash: wyhash
Maybe the link could be updated to point to this instead?
WallWextra··on New fastest portable hash: wyhash
The small key performance is very nice. It would be good to have more written about this new hash function, and less misinformed rant about siphash.
WallWextra··on Automatic Differentiation in Machine Learning: A Survey (2018) [pdf]
Those are a bunch of different ideas. It's the word "duality" that is insane(ly overloaded).
WallWextra··on What Every Programmer Should Know About Memory (2007) [pdf]
n.b. there would be a difference even without vectorization
WallWextra··on What Every Programmer Should Know About Memory (2007) [pdf]
Mazel tov. There are also people who went to "Principal" without being able to program at all.
WallWextra··on Immersive Linear Algebra (2016)
The only reason I was able to learn any math in college is because you don't need a computer to do it, so you can avoid the distractions. A browser, the source of all the distractions, seems like a really bad place to learn math.
WallWextra··on Linux Problems on the Desktop (2018)
Good desktops need more than good kernel code.
WallWextra··on How can we resist the seduction of the mobile phone?
I keep my phone plugged in on the other side of my (~7 person, locking) office. That works rather well.
