Some people are uncomfortable with touchers. Should they set the rules?
An alternative? I don't see why any country needs to take the role that the USA is filling right now. The USA is not some sort of peacekeeping organisation, they're enforcing their will elsewhere.

I completely agree that if China were in the USA's current position, the world would be much worse off, but that does not mean I think the USA's current position is desirable. If you do want to make me pick, I would say the European Union might be a good fit for the role since there is no European army and there are no serious or popular proposals for such a thing. Each country would still have to be convinced to take part in any sort of conflict. I currently see the USA (partly, of course, as there are many, many other aspects and I would not, for example, stop trade or anything) as a threat to most other countries (aside from the five eyes countries perhaps), but the EU in such a position would be more like a negotiation table.

> A language where the program is constructed by editing a running process in-place with a debugger/IDE, then the process is "saved" as an executable.

Others mentioned Smalltalk, but this is exactly how Common Lisp, and many (most) other Lisps work.

In Common Lisp, you start with a process that has a compiler (or interpreter, depending on implementation) and a REPL, and everything you do from there is modifying that process, called "an image". After you're done, you can dump the image into a standalone executable (but unless you're distributing executables or care about startup time, it's not something you'll likely do). Source code in Lisp is really a set of operations you do on that image.

The Lua language was originally a data templateing language [0], and is still very good for that, but like all such things, it grew. Contrary to Greenspun's Tenth Rule [1], Lua's implementation of Lisp is not at all ad-hoc, informally-specified, bug-ridden, or slow.

I don't believe the downvotes are all from clinically depressed people. For example, people say there's no opportunity for them, they can't get a job, they can't invest, they can't negotiate, etc. I point out that hundreds of thousands of people walk thousands of miles just for a chance to get into this opportunity-less country. I point out opportunities, like where they can get a free MIT education.

I get downvoted to hell :-)

It's not that I mind the downvotes, I just think it's a sad commentary on the current political climate that people feel that way. Even Hillary Clinton wrote a whole book about her being a victim in the last election.

From Wikipedia:

“In a 1987 study by the International Conference of Symphony and Opera Musicians, it was shown that 27% of interviewed members admitted to using beta blockers such as propranolol for musical performances.[70] For about 10–16% of performers, their degree of stage fright is considered pathological.[70][71] Propranolol is used by musicians, actors, and public speakers for its ability to treat anxiety symptoms activated by the sympathetic nervous system.[72] It has also been used as a performance-enhancing drug in sports where high accuracy is required, including archery, shooting, golf[73] and snooker.[73] In the 2008 Summer Olympics, 50-metre pistol silver medalist and 10-metre air pistol bronze medalist Kim Jong-su tested positive for propranolol and was stripped of his medals.[74]”

Manuscripts are very hard to transcribe, and only get harder the older they are.

But neither of these will help for something as complex as this.

His trial in the UK is indeed just about 'going on the lam' (ddg tells me that means fleeing), I expect that won't result in a large punishment. But I think most people would agree that USA's laws and practices with whistleblowers are unjust. The news reports I read said that the MEP (or was it MET? Some UK police force) got a heads up from Ecuador and arrested him on behalf of the USA rather than his crime of fleeing in the UK.

Generally, sure, the USA is a democratic country and the UK has an extradition treaty. It is in most cases fine to honor the treaty and hand a person over when it is plausible that they committed a crime there. In Assange's case, I think we feel very differently from how the USA government feels about his actions, and we would dole out a very different punishment (if any).

Thanks, I'm glad you like it.

It was something I whipped up in 5 minutes about a month ago when I really wanted a quick and dirty color picker. I do use it in practice.

One shortcoming is it doesn't visually show the color after you copy it, but that could also be done with AHK. You could totally have it show a small 16x16 window with the color which would disappear after 2 seconds and would get refreshed after you pick a new color if it were still visible.

You could even go 1 step further and change it to zoom around your cursor on key press, and then copy the color on mouse click while showing a 16x16 window color preview on hover. That would be the ideal solution, but something like that might be 3-4 hours of hacking around with no real AHK knowledge instead of 5 minutes and that wasn't worth it to me at the time.
I don't know how precisely it translates into this situation, but there are several other distress codes where the coded nature only has to pass the harasser not "everyone". In aviation, the hijack code. In POW cases, blinking Morse code. In mall or convention security, calling the cops and asking for "Nora" ("Need Officer Right Away"). In law enforcement, 10-codes.

> I’m just saying I literally can’t imagine that being useful for stopping someone I’m afraid of committing crimes against me

Imagine that you're a typical stature (or even smaller) woman who is being harassed at a bar by a typical (or even larger) man. Imagine that the security staff has been selected and trained for their ability to provide security in a bar. You can't imagine how being able to communicate your need for security or assistance discreetly and unambiguously to them could possibly be helpful?

I don't think it's that a woman intending to get help with a harasser cares that "every female" knows the code phrase, just that the bartender and security staff do, and that it's going to be able to be unambiguously communicated to the staff before the harasser can intercept it. It's not a matter of shame where secrecy from all is important.

irreducibility of subjectivity?

subjectivity is subjective. its axiomatic. no one argues that everything is reducible or reductive. ever heard of the explanatory gap? no, we have axioms, which are self-evident, that subsequent truths are based on. axioms are the epistemic grounds of reason, and consciousness is the epistemic ground of all knowledge and experience. no consciousness - no knowledge. and just because we can't prove it objectively doesn't mean it doesn't exist! how absurd!

Dennett's arguments are not taken seriously in many academic philosophical circles. There is a joke about the title of his book, ever so humbly titled "Consciousness Explained", that is should be retitled: "Consciousness Explained Away".
We're all just waiting for a formal Rust Reference Manual to be published, so that the official ANSI/ISO C and C++ standards can be replaced by a single-line reference to that. Since all practical C/C++ programs will necessarily invoke undefined behavior at some point, doing this is even 100% legal by the previous versions of these standards, even though it means rejecting the older C/C++ syntax altogether; it's really just replacing runtime nasal demons with a far more benign compile-time diagnostic!

I agree, I logged in just to upvote the parent. Any copy is better than no copy, and if you don't risk damaging the original, I don't see the downside.

This pragmatic preservation was already on my mind because of something that happened last night. I was driving on the motorway when a drunk driver caused a huge high speed crash right in front of me. I have a dash cam,and it captured the whole thing. The police officer on the scene used his body cam to film the incident from the screen of my dash cam. I'm sure it was a terrible copy, but it was an immediate backup.

Of course he then collected my dash cam as evidence too. Their digital evidence team must be on point too because I got a thank you email within a couple of hours which said they had already successfully downloaded the original recording and were sending my dash cam back to me.

Historians could learn a lot from this, ordinary police officers operating in difficult conditions are doing a better job of preservation than historians who's only job is preserving and studying historical artifacts under much easier conditions.

Laminar – semi-reliable UDP-based protocol for multiplayer games (Rust)
If US laws regarding whistleblowers are indeed unjust, he will have opportunity to argue that in the UK during judicial review. The UK refuses plenty of US extradition requests - far more than the US rate of refusal for UK extradition requests in fact.

The UK will not extradite him if he doesn’t get a free trial and the US is perfectly capable of providing one. He will then have plenty of opportunity to argue before a jury why he should not be convicted.

The notion that he is somehow above legal process and a strongman politician should step in to stop him facing due process is ludicrous, as well as the stupid idea that the UK is some sort of lapdog for daring to dispassionately follow legal procedure regardless of the celebrity of the accused. The fact that he is facing normal legal process where he wouldn’t in many countries where the legal system is politicised is a feather in the cap of the UK.
>It is sad how pop music on a Western model with its 12-tone equal temperament (or an East Asian model with pentatonic equal temperament) has, in the course of invading the whole world, gradually marginalized many local traditions that are microtonal.

> When you hit “save”, the serial number (se) incremented to reflect the change. As clients everywhere evicted their last-retrieved cached copy of the pets.com zone, your new change (with its new serial) bubbled out across the internet, and some indeterminate time later it finished going “live”.

This sorta implies the serial number has something to do with the caching mechanism, but it doesn’t. Record caching is based on the record TTLs only (which the author later mentions).

The serial number was originally used by the BIND master/slave replication mechanism for zone files (so called “zone transfers”[0]), which occur out of band of normal DNS lookups. Other name servers could use it for similar purposes, since the serial number is required in the SOA record, but I don’t know if an so. (In fact, the formatting shown for zone files is specific to BIND. Other name server implementations have their own ways of storing the zone records.)

This entire piece is written in a way that gives me a feeling that the author doesn’t fully understand DNS.

That said, I do somewhat blame the original DNS RFCs. For a long time BIND was the only name server implementation, and the RFCs themselves reflect this with RFC 883 and its updates being as much about BIND itself as about DNS. The DNS RFCs are kinda unusual in that way. It would be like there being an RFC for a specific httpd implementation as part of the http RFCs.

They didn’t help much at all, but the program was still new. Their support might be better now, not sure. I do think taking the program highly highly increased my chance of employment. I would not have made the right choices about what to take, my pace would have been much slower, and my self confidence for actually applying for jobs would have been way less. I am confident about this because I was taking Coursera courses and online tutorials before the AppAcademy program. Coursera is awesome and I learned some great stuff. I also realized that I was good at programming, which gave me the confidence to apply to AppAcademy. But AppAcademy was truly a boot camp, very intense, and pushed me through everything I needed to get a job. And I was also contractually obligated to at least try to get a job.

Quantum computing includes classical computing as a special case, so in terms of time complexity, it is strictly faster.

But I think this page is actually just a list of algorithms that take advantage of quantum features, so of course they will all be "faster".

I work at YesLogic and answered a similar question on Lobste.rs recently: https://lobste.rs/s/7op1vm/my_first_3_weeks_professional_rus...

The gist of it (as far as I understand it) is that at the time Prince was started (around 2003?), there wasn't a declarative/functional programming language out there to use that was fast enough, or had as much interest in low level control as Mercury had. The founders were pretty convinced that this was the style of programming they wanted to do, and the creators of Mercury were locals to Melbourne, so that kind of tipped things in Mercury's favor.

In general we tend to use the functional/typed parts of the language more than the logic parts of the language (although that can be handy at times). Pretty much any form of programming can benefit from being expressed in that way. It might be that the team is so highly competent, but the Prince source is one of the best I've seen, even after all these years, and it's still reasonably easy to make changes without fear. That's mainly what we get out of Mercury.
