I think it'd end up like what happened when Ma Bell was broken up. Over time the companies have merged back into just a few and not everything got better, and tech evolved rapidly which complicates direct comparisons but at the same time, I've got several phones in my home and none of them have "property of AT&T" engraved into them. Some things improved.

Companies are amoral monsters who care about nothing but making money and there will always be a struggle with regulation followed by deregulation followed by more regulation as people push back against abuse, but that cycle has kept things in relative order. Companies have gotten very good at inserting themselves into government, directly and indirectly, to stand in the way and prevent the people from keeping them in line, but I don't think it's entirely hopeless yet.
This wasn't the most robust crew. They were at a local minimum, both topographically and risk. They were safe where they were for at least a few days. Hiking out might have been beyond their ability. Having read some stories of people who didnt get out of these situations, it's not usually the first mistake that does it. It's the process of trying to get out that results in digging a bigger hole. I think they made the right call to abort rather than increase the risk.

I recently took a week in the Carolinas and Tennessee. After twenty years in the Bay Area the difference in the presence of young women everywhere was so remarkable that my wife remarked on it and asked if the place was heavily skewed female.

They do work on environmental issues and smog like almost no one else. There is a strong realization that pollution should be curbed, and progress is visible on the span of a couple years. Also there is a progress in garbage sorting and recycling. Provinces have a high level of autonomy, country and municipalities work hard on making health insurance and services more accessible for everyone. Therefore, at least half of your points are already in works and progressing fast. People tend to think too much of stereotypes about China. Regarding traditional characters - this will never happen, there is so much content already using the simplified ones (even idea to do that sounds ridiculous).

Exhausted. I don't work in IT, but I suspect my job has a lot of parallels. I make my living running live sound for bands and small music venues, while also doing corporate AV for a large AV contractor. Despite what outsiders may think, working in the music industry is murder on your social life. Sure, you get to go to neat concerts and meet awesome artists, but it also means you're working most weekends and many evenings. During the day, there's a good chance you're sleeping. I often don't get home until 3 or 4 in the morning. The lows are low. I'm often so nervous before a show that I almost vomit. The highs are great though, I often go home after a good show in a state of ecstasy. It's amazingly satisfying on the rare occasion when I'm able to enter a flow state while mixing.

The corporate side is probably about what you'd expect. The hours are long, the pay is low, and most of the work is boring and/or ethically challenging. While some of the events are interesting, (I had a blast working with the guys from Earth Science Information Partners) I've also worked back to back 4 hour Amway pitches and helped set up mics and projectors for boiler-room style real estate schemes. It's the kind of job where your coworkers are really important. I really enjoy working with my normal team, but one day with a bad team can really undermine my self confidence for days afterwords. There's a lot of really crappy political stuff that I'm trying to navigate.

Personal life? I'm financially stable, I have a few friends, no romantic relationships nor prospects. The latter is sad to me, but I'm a tough sell. I really enjoy being alone and highly value my privacy, probably to a fault. My schedule is so variable and full that the very idea of coordinating that with another person makes my brain hurt. My dad died recently, which was rough. At first I was a bit numb to it, and really threw myself into work and keeping busy. Now, I feel like it's all catching up to me. The flood of feelings and nostalgia are beginning to creep over the spillway of my hastily constructed dam. The overwork is beginning to take a toll physically and mentally. I've had to dial back on a lot of the live music stuff.

I sympathize with those who want to move to a cabin in the woods. I'd take that life, provided I had a well stocked library and some musical instruments with the means to record them. My fantasy is to just disappear. Quietly and carefully I'd made the arrangements in advance, and then one day I and all my stuff would be on the road to some distant city, without so much as a note. I don't know why that idea appeals to me, but it may come from the same part of the brain that nags you to delete your entire source tree and start from scratch.

Ask HN: Protocol Negotiation in Intergalactic Computer Network?
A while back, I remember reading how back when they were working on the Intergalactic Network under Licklider, etc., one of the problems they tackled was how to have two computers negotiate a common protocol to communicate with each other. The problem, if I remember correctly, was framed as a first contact scenario of two alien civilizations.

I have now forgotten where I read this and can't find any resource on whether they made any progress in this field. Any one has any idea what I am talking about here? Are there any publically available records of how much progress they made, which parts of the problem they were able to solve and what were those solutions?

> In his book, Shadows in the Sun, Davis (1998: 20) recounts what is now arguably one of the most popular ethnographic accounts of all time

> Since publication, this story has been told and re-told in documentaries, books, and across internet websites and message boards (Davis, 2007, Davis, 2010; Gregg et al., 2000; Kokoris, 2012; Taete, 2015).

Right, and the guy I was replying to was claiming that speed on a non-electric "Xootr".
The exponential captures the idea of slowly perturbing an object by a small amount. Suppose you start with some object, perform some action on it, then add the result back to your original object. On a manifold you can't add objects together, but you can push your object a little bit along a tangent vector (think of the tangent vector just as the slope of a function at the point). If you just recursively do this operation, as long as the amount you push by grows smaller you end up at a well defined point. Effectively you have pushed a point 1 unit along a geodesic (locally shortest path). So you can define the exponential map in much more generality as a Taylor series for more interesting things than just functions on R. For example given a (matrix) Lie group G and its Lie algebra (actually the tangent space at the identity), the exponential map

exp : g -> G

is defined by its Taylor series

exp(X) = 1 + X + (1/2) X^2 + ...

(X is some n x n matrix).
That's an interesting reaction... imho, the idea that change can't come out of nowhere is the most intuitive part. "How can something arise from nothing?" is a puzzling philosophical question precisely because our intuition is that it's impossible, that everything has to come from somewhere (and conversely, nothing can simply disappear). Functions where this expectation is violated -- e.g. non-constant continuous functions where all derivatives vanish to zero at a certain point -- feel like bizarre exceptions to me.

Crypto coins internals or how to view Crypto world
Do you know that every crypto coin use some NoSql database to store transactions and internal data? In most cases useing key-value DB, 90% it is leveldb. In Monero it is LMDB. So you can find this database on your PC and view binary content via FastoNoSQL, may be you can find how to earn extra coins to your wallet :) P.S. Wallets as well use key-value databases for store recovery phases or user credentials :)

Good point, but would you leave your car without solar panels out in the hail?

If it really breaks, then you have a car just as useful as before, until you get the solar panel fixed.

Whether this is good or bad comes down to how much the panels will add to the cost.
Sorry but part of making information accessible is communicating using less formal language. I could have titled the post “A comparative analysis of certificate-based authentication relative to other SSH authentication mechanisms”. I am capable of using fancier words too. But no one would have read it. I’d have been preaching to the choir.

Perhaps the title could have been more diplomatic. Perhaps I was not sensitive enough to the feelings of folks who use non-certificate-based SSH authentication. But it’s just a title. I meant no harm. <3

172lb is a lot! Thanks for doing that. But I think solar panels meant for rooftops have a lot of weight in the aluminium frame, and are think glass. I can't imagine a car manufacturer putting thick glass above the aluminium skin of the car if they didn't have to.

Most of the STL does no allocation. The containers allocate only at known places, permitted during initialization. They also know how to allocate from provided bespoke stores, which are permitted, in JSF code, even after initialization is done.

So, no, the STL is very much on the table, as in any competently constructed work product.

“Proportional to” hides a constant factor, so your analysis is wrong.
> but prosecutors play a large part in our national incarceration problems

The problem is pro-punishment politicians. Singling out any particular office/position misses the point.

Even when judges practice discretion, pro-punishment legislators step in and introduce mandatory minimums.

And even when prosecutors practice discretion, pro-punishment judges will step in and force them to prosecute cases that the prosecutors don't want to prosecute [1].

I invoked the personal experience only as evidence that I did what (little) I could to push along the project that I think has the most long term potential. I'm not criticizing without at least trying to do what I can.

In short, the reasons gccgo produces worse code than gc are the result of fairly basic optimizations that are/were missing. For example, open-coding string slicing [0] and string equality [1] is enough to close the gap in the TimeParse benchmark in the blog post above. In fact, with those changes, gccgo actually produces better code than gc, because the full power of GCC can be unleashed on the IR, and GCC has more aggressive optimizations than gc.

> This isn't to say you should take everything anyone with more experience says at blind faith, simply that dismissing without understanding is counter to a growth mentality.

Quite honestly, I think you're more guilty of dismissing without understanding than I am. It's true that I haven't been programming for decades, but I've spent two years dealing with the Go toolchain's shortcomings on a large Go project, and six weeks specifically on a passion project to improve gccgo. Of course it's possible that I'm wrong! But I've spent a while thinking about it, and often just as relevant as experience is a fresh, outside perspective. It's easy for a team to get stuck in tunnel vision or groupthink.

Context switch is switching between processes or threads that a CPU core runs. In parallel computation it's well known how to avoid that: keep the thread count equal to hardware core/thread count.

Green threads enable concurrency but not parallelism, so they are not applicable to accelerating computation.

(core.async isn't actually green threads, except in ClojureScript, but its thread pool is more for working around blocking calls than exloiting parallelism).
Thanks for the reply. Both were illegal immigrants; one had a license and wasn’t DUI. The answer to why I think this is caused by the illegal status is that, pertaining to when the Honduran immigrant (the DUI one) hit me, I went out of town with my wife during the period of time when he was supposed to go to court and obviously go to jail because he had done the same thing 11 months before and actually left the scene in that case, so he was already wanted, and so I thought “surely he will go to jail for many months...” when we got back to town I called the prosecuting attorney to ask her what happen with his sentencing/verdict/etc., and she told me that he didn’t show up to court. So I asked her “so are you going to go arrest him?“, And she informed me that they don’t handle cases like this by going to the house to arrest him. I was confused thinking ‘oh so this is going to be like an outstanding warrant and he will get arrested when he gets pulled over at some point’. I was frustrated but I thought ‘well it’s only in evitable that he will go to jail eventually’. But then I realized, ‘wait a minute, if he was already arrested for the same thing 11 months before and they didn’t even keep him in jail longer than 12 hours in the drunk tank, why would they ever put him in jail...’. That’s when I started asking more questions and found out (from the PA’s secretary) that the reason they couldn’t arrest him is because if they were to try him for contempt of court they would end up having to deport him, and this is when I found out we were living in a sanctuary county.

So the reason he was drinking and driving isn’t because he’s an illegal immigrant or because he was from Honduras. It’s because there is no rule of law when you are letting people break your laws to get into the country to begin with. And if there is no law there is no accountability. If I didn’t have to worry about getting in trouble myself, I might be out drinking rum runners on the highway 24 hours a day.

We all like to think of ourselves as virtuous, but, without accountability to the rest of society, we are just wild animals on this rock floating through space.

I wrote to a maintainer of the MSVC lib. He says their lib has to work on all amd64s, but some (specifically, AMD before K10, and Intel before SSSE3) have no popcount. He says their intrinsics are defined to emit exactly the instruction named, unlike Gcc's, so they can't use that in their library.

No explanation why they use the loop form, except that the code hasn't been touched in a long, long time.
