I think I used the word vouch incorrectly. When you sign a commit you indicate that your changes can be applied only on that particular parent even if all files or diffs were bit for bit identical. If it didn't work like that someone could take your work and place it in a completely different project and claim it was signed by you.

Note that even with signed commits there are same gaps in the system. For example without signed pushes someone can take your signed commit from branch "test" an push it to "master".
You are both right. They exploit the poor by extracting from the middle. Meanwhile, the rich have moved their assets offshore or into anonymous properties.
I'm pretty sure Twitter's langid uses character n-grams. You'll see a tweet that's plain English that happens to match n-gram statistics unusually well with some other language, which pushes the likelihood score to just above English. (I checked this by running an example or two through my own langid code.)

It shouldn't be hard to improve on by treating the score on a tweet as bayesian evidence to combine with a prior from preceding tweets.

I'm not worried about the normal, full-time delivery guy. I'm worried about the fill-in, all-the-regular-guys-were-sick guy. Someone who doesn't have a good job and reputation to lose.

You also have to think about it from the delivery person's perspective. They won't really know if someone is away from home or just lazy. They could be opening the door to an assault or any manner of sexual harassment.

I wonder if they'll get resistance from drivers after they really think about the situation they could find themselves in. There's some security in knowing where your attacker lives, but not much if we're talking apartments.

Finally, will Amazon let you participate if you're in an apartment complex that already has lockboxes? Wouldn't that kill the delivery efficiency?

Do note that you don't need anything more than 22 random mixed-case letters & digits: 26 lower-case letters plus 26 upper-case letters plus ten digits is 62, and 62²² ≈ 2¹²⁸.

It seems to depend on the program. cat is very quick to respond to ^C whereas in vim, less and elinks often a large amount of text is printed before ^C is echoed and takes effect, like you describe. I suppose that has to do with the size of chunks written.

In reality though it's more about the trickling than actually mimicking a proper serial connection.

Windows are made of glass, and most deadbolts are installed into little more than a 1/4 - 1/2” of wood. In some places, they’re held by little more than mounding. Both are absolutely trivial to knock open, with the quality of the lock itself being far less important to the overall picture. Securing a door goes like this:

1) good deadbolt mounted into thick wood with a big strike plate and a sheet of sheet metal attached to the entire length of the stud with 3” screws, so you can’t just kick in the door. They sell kits like this oh amazon for usually sub100$.

2) good deadbolt.

3) steel door, because a 15lb mallet will knock through pretty much anything else and, if you have a door not visible to neighbors (like a backyard doors) no one will even notice.

4) an alarm system, because if no one is coming, steps 1-3 are irrelevant. Time defeats all security measures.

5) thorny bushes under all windows, motion-sensing lights on the entire perimeter. This keeps no one out, but if your house looks like a pain in the ass to get into, someone else’s will get hit. Outrun your neighbor, not the lion.

6) and if you’ve got the cash to spend, hurricane-proof glass and window stops will make it very unlikely anyone is getting in through a window either.

7) and that’s all still just to make you less attractive than a neighbor, ‘cause if I can get into your yard, cutting away some siding with metal snips and knocking a hole in your sheetrock is trivial. Walls are more psychological than structural in most modern home construction.
I'm not sure I'd call Julia a dynamically typed language, each variable can have one and only one (possibly abstract) type which allows the JIT to avoid boxing and opens up plenty of optimisations.

I'm not particularly convinced that Julia's object model leads to inefficient memory access either.
The big question is, did Apple state the 1 in 1 million number knowing that they were having supply issues, meaning that the original component was more accurate? This must have been known in some way before the keynote, so I wouldn't be surprised if this is "old news" as in Apple told supplies to do this around or before the keynote.

Of course we won't know how much things will change from Apple, but I assume it's not a 50% drop (and even if it was, it's still apparently 10x better than TouchID).

WordPress Websites Management Made Easy with MainWP Plugin
I hear what you are saying, but I feel like I see the opposite in marketing campaigns. There are instances where companies play to their strengths. An example would be Verizon touting the quality of the network. I could be wrong, but I'm under the impression that Verizon does actually have a better cell network than it's competitors.

But I think that's the exception, not the rule. Many more companies seem to use marketing to prop up their biggest weakness. McDonald's advertises that their food is delicious, but nothing could be further from the truth. Coca-cola advertises that their products will make you happy, but in fact they will make you morbidly obese and eventually kill you. Samsung advertises that they are the innovative, but their business model is copying other products.

Branding which boldly contradicts the most obvious and glaring weaknesses of a brand is the most common type of branding. I don't need to be told that a Dodge is a vehicle that can transport me. I need to be told that it's going to be exciting and stylish; of course it isn't, but the illusion may suffice.

Every corporation, every private charity, and every public institution that I've worked for has been wasteful, and the corporations have been the worse offenders in that regard.
> Which specific code did you benchmark?

I had a csv file with ~16k entries. Each entry has a lat, lon, name and id.

The task: given a (lat, lon) pair, list all entries within 5km.

The simplest straight forward solution is to iterate the list, measure the distance of each item to the given point, and add it to the return list if the distance is within the desired range.

No crazy optimization or anything.

The results were something roughly like this:

The D version runs in 2~4ms when compiled with optimizations turned on to the max, and about 6~8ms without optimizations (just default compiler settings).

The Go version runs in about 6~8ms. (The Go compiler has no option to produce optimized code).

The python version runs in about 50ms.

That's 10x slower than Go and 20x slower than D.

This is python 3. Using pypy shows absolutely no difference in performance.

Obviously the time to load the data from the csv file into a list is not counted in the above results.

> I’ve seen multiple cases where Python beat C/Go because the app used something like dictionaries which was heavily optimized C code in the standard library.

That's exactly backwards.

The Go and D versions use structs which are compact data structures that pack the data together. So the entire array fits in one contiguous block of memory.

Python has no concept of structs, so you have to deal with dictionaries.

In general, writing optimized code is not a good idea. You should almost always write the most plain and straight forward code.

Because fast languages are fast by default, there's no optimization required. The straight forward solution is fast enough.

If you are writing Python, your code will be slow by default. You will need to think about ways to optimize it if you want better performance.

First, let's see some real movement on anti aging. AI can play go and drive cars, what'the anti aging equivalent.

2nd, we've already added those 20 years of average life in most places, without much anti aging. Antibiotics, sterile surgery, vaccination, geriatric medicine. Childhood deaths went down a lot. Mid life deaths too. Old age is much longer than it was with life expectancy at retirement trending towards 90.

We've already had the economic/societal consequences in the west/north/rich places. The first (childhood survival) too in the form of population explosions still in play in some places.

I doubt anti aging has bigger effects than that within the next 50 years, even if life expectancy at birth leaps to 100 tomorrow. Anyway if it really slows aging it'll extend people's productive middle life, which is mostly good economically.

> For some reason it's just not happening.

A major part of that issue is the voting population. Only people who have already overcome the "getting housing" hurdle are permitted in the elections that shape zoning laws.

There's still some variance there: homeowners profit from high housing prices, while renters profit from low ones. But even for renters, who theoretically want zoning laws relaxed, it's often not a top issue. Given that "weaken zoning laws" is a broadly conservative position here, weak-zoning candidates are usually blocked by the general liberalism of urban areas.

(And at least where I live, technocratic Democrats who might support progressive policies and weak zoning get crushed by entrenched Democrats with more funding and union endorsements. A viable candidate would need to be technocratic only on zoning laws.)
This test isn't for life longevity, but to combat the frailty common at the end of one's life.

How to write a stunt server using raw sockets in IPv6
Ask HN: Current state-of-art data science / deep learning packages for Windows?
Hello, I was away for three months and need to update my hobbyist data science / deep learning set of packages for a Windows 10 laptop with a 1070 graphics card. It is on Anaconda for Python 3.5 at the moment and I remember some external packages were pretty cumbersome to install. Any tip or list for updating without breaking the hard-earned stability? Thanks in advance!
Again, that number is very misleading. Apple is "lying with statistics" basically.

No attacker trying to break into your iPhone's authentication will use random images. They'll build a profile off your existing online photos, and then try to fool the FaceID system that it's actually you authenticating.

Suddenly that number drops by about three or four orders of magnitude.

This is harder to do with fingerprints because you don't keep your fingerprints online.

>Setting typecodes and vals doesn’t slow things down by many orders of magnitude.

What about blowing the cache by having every access involve multiple pointer dereferences?

Virtual calls are absolutely slower than normal calls.

But yeah, 100x is not likely from virtual calls unless you're forcing a cache invalidation on every access. Running a CPU without cache brings you down 100x-200x (literal) in performance on most modern machines.

(The Cell CPU was almost exactly 200, which is why Sony did TONS of PR and tech talks on Data-oriented Design because the Cell would be useless without cache aware programming.)

But on further reflection, you said "this is one source of 100x, not unboxing on its own" so we're more in agreement than disagreement I guess. My point is that virtual calls and dereferences can definitely be a huge performance hit if the cache/TLB can't keep up with it.
Good question. There's only so much room on 4x6 labels. Also I haven't seen a shipping solution that automatically prints customer notes on label. As for address lines, UPS has a finite amount of characters per line before they drop off.
RedHat and Valve do way more for Linux gaming than Canonical. So I agree with the above, Canonical's decisions aren't affecting Linux gaming that much.
> The boat carrying it should, in theory, be less likely to become a shipwreck.

Alternatively, only a few boats would have had one, and the ones that did were using them to strike out further afield than their less well-equipped contemporaries. Since they could be more confident about their location, they could venture further from land and might get caught by storms more easily.
Unlike a smart mailbox, this lets them plug your front door / the smartlock business line into Alexa. They get to do the same with video surveillance of the home, which they’ve been pushing with their fashion app and whatnot - so this means in the future they can possibly integrate these inward-facing cameras into services they’re already developing.

It seems like this is a play for pushing a smart home ecology around Alexa.

"successful writes since start" has a time value associated with it, right? I think what you want is not to correlate "time since start" and "successful writes since start", but to just do a derivative of the "successful writes since start" metric. This is just like the networking stats on Linux hosts.

I have something like: FROM default net WHERE host =~ /$Host$/ SELECT field(bytes_recv) mean() derivative(1s) alias(In) GROUP BY time($interval) tag(host) tag(interface) fill(null) FORMAT AS Time series ALIAS BY [[col]] [[tag_host]]/[[tag_interface]]

That's in my Grafana query.

Aside: I sent the TimeseriesDB reference to a friend that just a couple days ago asked about options for storing metrics on storage servers. I had told him about my experiences with Influx, had mentioned Prometheus and also Sentry has some sort of internal TSDB they do on Postgres. In reply to the TimeseriesDB reference, he replied that he was all about InfluxDB now.

This came up in a similar form in the discussion about IoT devices and privacy.

If you don't think this is a problem, or businesses have a "right" to pursue profits at all costs, you are a part of the problem and need to kindly find another industry to harm.
