We recently discussed this in another thread, but one of the low observability (stealth) characteristics of the F-117 was a reduced radar cross section (visibility) using flat sections of fuselage in a faceted manner.

This was calculated by hand by Skunk Works engineers. They didn't have the benefit of computerized physical modeling back then. They were able to reduce the radar visibility to a size about that of a bird (it's actually a little larger, iirc).

My understanding with Zoltan is that he just looked birds flying at 500-600mph. He claims that he invented all this complex, custom gear accompanied by advanced-sounding jargon, but the US military dismissed it as hyperbole (which Zoltan is known for).

The B-2 had the benefit of computer-aided physical modeling which explains it's lack of facets. The B-1 and B-52 also have low observability characteristics to reduce their radar and infrared characteristics (although they aren't known as "stealth" aircraft).

I think that stealth aircraft as we know them are largely obsolete. Hence, the increased focus on UAVs and satellites. I have some ideas about where to go next, but the costs would make the B-2 look like a Girl Scout cookie sale.

Disclaimer: I worked on many of the above-mentioned aircraft.
Cute enough, but ”surprisingly powerful” is excessive hype. The functionality here is pretty basic: Photoshop 1.0 (20 years ago) blows it out of the water. Also, the “Instant” button at the bottom just generates JavaScript errors and fails for me.
I've never looked at commute time data before, so I'm just an armchair analyst.

It seems to me though, as a driver, that commute times are dominated by accidents. And certainly while you could estimate the mean probability of an accident based on the number of travelers, the daily variance seems insanely high and its unlikely that any amount of training data is going to decrease that much. I wonder how good these results are going to be.
interesting technology, has a lot of potential.
oh, i just added another item in "to learn" list
Can someone explain to me how duckduckgo works? I didn't find much about it from a couple of searches.

It seems it just scrapes other search engines, is that true? If so, won't ddg just be blocked by those major search engines if it ever picks up any useful traffic?

Not trying to be inflammatory, just curious.
It does, but you can't scroll part of the page in the native way -- iOS users are very accustomed to the kinetic scrolling, anything even slightly different is enough to throw them off and make your app seem "weird".
Most of the techniques mentioned in this article relate directly to the way our brain makes associations and forms memory. Learning something is a two step process: retaining the new information in the brain and then forming association between that and the things that we already know.

I have observed that trying to recall something that I have learnt ensures I retain the information instead of simply getting the illusion of learning something.

Mixing topics essentially allows you to create new associations in the brain about the topic. The stronger the association about a topic, the more you retain the information. Another technique that works really well is trying to apply a new topic to your own life. By relating new information to things you already remember, you create the pathways to remember and retrieve certain information.

It is interesting that there are no children in Atlas Shrugged.

I guess biological reproduction and the moral implications thereof did not cross Ayn Rands mind at the time. Either that, or children are somehow exempt from objectivism, which begs the question of how or when to distinguish between child and adult.

Then again, I only read Atlas Shrugged, and maybe Ayn Rand expressed her thoughts on the subject elsewhere.
I would guess a well done scala project would be at least one order of magnitude shorter than a comparable python project. You just can't get the same level of abstractions without a type system to help you out.
Have to agree with oji0hub. Once you factor in cost of living, health system, governmental support etc. Life in Germany is actually ahead of its American counterpart.
> First, why on earth would you still be using non-parametrized queries.

Legacy software no one wants to maintain, and no one is paid to maintain.
the biggest impact of such for such corporations is the removal of the foreign income tax credit as is also makes it somewhat uneconomical to attempt pet to doge taxes vis the high tech gambits of underpricing a virtual IP and selling it to another controlled corporation to hide revenue in at the lower tax rate

In fact is has been recommended by most economists
Much softer than America. There is no death penalty, for example.
Welcome in the real world. It's almost the same like in traditional maintenance, were you have to change filters in HVAC or change mechanical parts all x hours of running and so on. Funny it's also an Cobol thread on the first page of HN. That code does run for years and years .. and I read here make everything new every 2 years. Big projects are not even done in 2 years .. I'm work in industry automation and I'm more and more happy, if a new thing has no computer at all. So much work, so short life.

shouldn't it be "its"?
Missed that earlier, added it now. Thanks.
Ok, so why do you advocate open spaces?

Personally I hate them because they destroy my productivity and that's the one thing I enjoy about work.

The trade off is that I hear a lot more office gossip as well as lots of details of my coworker's personal lives, including their children's play date plans, personal health issues, etc. If that's what my boss is after then the open office plan is working splendidly.
Probably more useful to focus on remote vulnerabilities that matter like CVE-2012-0830 which affected 5.3.9 of which according to the post 0.14% run. Also many bugs are highly config dependent like CVE-2012-1823 which is serious but only affects apache with a specific config. So counting a version increment to indicate level of vulnerability - you probably need to add to the survey to get a real indication of the level of vulnerability out there.

However, it's interesting data of what's out there so thanks to the author for that. Most of the infections we see are default installations that haven't been configured and a bot raced in and infected. Or old PHP apps, themes, plugins or components like thumbnailers that were the vector. Targeting PHP itself is quite rare because there are so many vectors via the PHP applications themselves that it's not needed if you just want to own a few thousand boxes for your botnet.
As well as your future self, weeks from now, to avoid having to say 'What the fuck was I thinking when I wrote this?'.
> Keep in mind, Wikipedia is at scale that most web applications will never, ever get to.

As I read the article I thought exactly this. Scaling is a nice problem to have. I keep playing around with Nginx, elasticsearch, and other tech that's supposed to help PHP's performance problem, but from personal experience, missing database indexes for complex joins have been the issue every time. I'm unlikely to get to use the tech I play with unless I switch jobs.

But back to the point, this is a great writeup, and I think a big step forward for both PHP and HHVM
I work in an open office and it's certainly got a fair share of ups & downs. It makes for a more sociable office resulting in a stronger 'team' feel. However, the music/noise/chatter force me to wear headphones (and crank them up). Even with the 'phones, I'm definitely more effective working from home (even the team agrees).

I'd like to see companies implementing mixed layouts, perhaps where teams work together in open offices, but not the entire company/multiple teams. Or - as per the article - a mix between working in-open-office and from home.
No, the lesson is don't commit credentials and if they leak then revoke them immediately.

and use least privilege to make sure that if you do screw up it's as minor as possible.
That argument was made when the first recorded music came out (people won't buy sheet music, they'll just listen), when audio cassette recorders came out (people will just record from the radio, they won't buy LPs any more) and when MP3s arrived on the scene.

In all cases the industry adapted. The film industry will change and adapt to the new world.

We'll always desire entertainment and someone will always find a way to do it.
I can paste a table into Calc OK. It was a simple effort with a,b,c,d in row 1 and 1,2,3,4 in row 2. The numbers came in as numbers OK. Paste as unformatted text is rubbish (single column of data) and I think I might file a bug for that.

Sorry, I get you now about auto updater - software updater not [Google: Excel auto-updater]. That's not really a thing on Linux because when you update the system, the whole thing updates - apps and all.

The pace of development in LO is absolutely amazing but there are some horrendous bugs with near immortality status. If you can put up with them then use it. No software is perfect but LO is moving at increasing speed towards the light.
Intel spent money to prevent their competitor from leveraging speedups from their compiler. It would have been less work for them to simply use feature detection on AMD chips, since Intel already has to implement feature detection for their own chips.
The implication is that minorities that have been historically discriminated against and are disproportionately poor will have fewer kids. This is a bad idea that people have 'tried' in the past and is ripe for abuse.
Fair enough. On a fast enough machine. This is off-topic, but while on my beefy dev desktop I get similar times to you, this was absolutely not the case on a much weaker laptop I used sometimes during travel - and the latter is more representative of how regular people experience things.

(Also, FWIW, loading delay of HTML pages on said beefy desktop, as tested right now, are consistently about 750-1500ms for me.)

More on-topic, these times apply only when the pages are hot in the browser cache. On my desktop, the first-time switch between "drafts", "sent" and "inbox" takes around 3 seconds each, and only then it is instantaneous. So regular users are likely to experience these long Ajax delays more often than not.
George Hotz is an excellent programmer and presenter. I like the way that he talks and explains things.

> There's always been this thought that I've had, that advertising and "paid" attention is really in no one's best interest. You're likely to get users who really aren't going to get any value out of your software, so your churn increases, and you've also just paid for that user that's churned. These things get harder to tease out since it's almost impossible to ask "show me all the churned users this period acquired from advertising channels." Maybe that's possible, but you'd have to do a lot wrangling together to get it all working.

Correct me if I’m wrong, but isn’t precisely that kind of analytics simply table stakes for any modern crm/marketing/customer intelligence suite in 2019? It seems like that is absolutely a solved problem.
Whoa there with the false equivalency. Helicopter money would be more helpful than propping up the wealth of the top wealth brackets using price floors through broad scale asset purchases. Literally give away hundreds of billions of dollars to citizens who will spend it right this minute. Have the government be economic demand of last resort to steady the ship until people can actually move about again. There will be no inflation to speak of due to how GDP has plummeted over the last few weeks.

Monetary velocity > asset price protection. The stock market isn’t the economy, people producing, consuming, and exchanging fiat in the process are.
Can confirm that breathing is super important in speaking; my sister has the weird habit of continuing to talk until her lungs are nearly empty, to the point where you can hear the 'distress' in her voice. It's a bit annoying tbh.
We have to keep in mind that this is unlike a anything anyone alive has seen. Nature is essentially holding a gun to about 1% of the population and demanding we stop working and having fun.

So we stop working. However you cannot stop working so much that it causes more damage than that. We cannot and will not stop food production or distribution. This is a voluntary action to save lives, you cannot let it endanger more lives than what it is trying to mitigate.

Anyone remember ad networks like The Deck? I still find the idea appealing to try and relaunch on their original premise & values.
Most (in fact, almost all) advertisements are not on “public space”, they’re on private properties.
"No ethical consumption under capitalism" is no excuse for moral cowardice. Sure, I live in a society, too. But I refuse to make these sorts of excuses for it. That's quite literally the least I can do. But it's not quite the same as doing nothing.
Another bonus of telegram (as compared to WhatsApp) is you can access the messages even when your phone run out of battery.
Was there to document and distribute some propaganda, we did not get very close to the militant action, but a few things to report:

- At least one flash-bang (probably) and one tear gas grenade (definitely) were used on the capitol steps.

- Their duty as police is to protect and serve, so shooting would have been a terrible idea. Evacuation is not difficult in an ultra-hard target like the capitol, and a lot of civilians had bags, some of which definitely contained firearms. I also heard some shouts about fetching guns from hotel rooms (we did not stay overnight in the city). A gun battle would have been catastrophic on both sides.
This is a big problem for functional languages, and there've been a bunch of efforts to solve it. For example, Clojure's default dictionary type uses a hash array-mapped trie, with each level sized so that a typical block can fit in a single cache line. It's very common for the youngest generation in a generational garbage collector to be sized to fit entirely into L2 cache, so that you know that every write or read of a recently-allocated value will at least be an L2 cache hit. (Unfortunately, it's usually not practical to make it a L1 hit, lest you be stuck thrashing in the GC, so you're still looking at ~12 cycles.) Deforestation optimizes out allocation entirely, instead performing the next computation immediately on values that are already in registers. Many GCs will also try to copy nearby pointers next to their parents, so that the pointers aren't quite random.
in the last 3 or 4 years that the sequencing technology has exploded in terms of data volume, as well as modern computer hardware that can analyze that data in any reasonable time frame. That's whats enabled whole genome sequencing of disease patients to become something practical

As a computer scientist working at one of the major genome centers mentioned in the NYT I can attest to ben1040's claim.

In the last five years alone because of technological advances in sequencing technology we have moved from talking about genomic data in megabases (Mb) to gigabases (Gb). Illumina newest HighSeq sequencing technology is capable of 300 Gb per run, 10x more than there competitor ABi's SOLiD instruments which were released as little as 2 years ago!
Flash works okay for smaller apps: animating content, web banners, video players, but I've found that as the complexity of your app increases, you really end up fighting the platform in terms of maintainability. Especially if you're using pure Flash (where all your content is buried inside FLA files) and not Flex.

I think that Flex and WPF/Silverlight kind of got it right with a declarative GUI syntax that could be interwoven with code....the biggest problem I have with their approach is that 'making humans edit XML is sadistic'.
I assume by "consciousness" you mean self-awareness. A similar paradox is viewed within the context of quantum replication, i.e. an aboslute precise material copy of your body is created, maybe even more than one, so the question is, what happens to your "I", your self-awareness in that case.

One approach is to say "it doesn't matter" because self-awareness is illusory. It doesn't exist in the same sense as matter or fields. What does exist in your mind is memory of all state transitions ever happened in your brain. It's like a linked list going back, where each element is a state of the brain. That chain is mistaken for something that exists, whereas it's just a logically linked list of some data. You are nothing but information.
in my understanding:

“shell” is kind of a loosely defined term in this context, but i just think of it as a textual interface to the whole system. really it’s just a program that accepts text commands (or scripts) and performs actions on the system or launches other programs, and manipulates and displays the results. eg: sh bash zsh fish xonsh

“terminal” is pretty well defined as a graphical UI program which presents you with the shell of your choosing (historically related to teletype or whatever) eg: xterm Terminal.app Konsole iTerm alacritty

for the most part you can use any terminal with any shell, so the terms kind of coalesce into the more generic idea of a “command line”

also all of this is for unix-like systems, eg linux macos bsd. windows is... well windows

hope this makes sense!
"Well, where's the fun in that?"

Mother Nature is perfectly capable of razing cities herself if that's what she wanted to do, eh?

People seem to be coming around, regenerative agriculture is taking off, we're starting to ween ourselves off of fossil fuel. I think there's hope.
Nice, really like some of the examples, might use this someday for some quick project.

Would like an option to pay something and download the html to self host. I did the see the one time signup and custom url.
yea, that's what concerning about this. The burden will be put on sellers to self report or face a chance of being found out and extreme fines. Now multiply this by 50 states, you'd have to hire a company aka. lower profit margins in the end... Then multiply this by N countries and their localities and you will always be breaking few rules unbeknownst to you.

Basically what happens with any new tech, some become big players, tech becomes mainstream, regulating begin, innovation stifles, new comers are out of luck. Just take social media. There was no GDPR before, now as a company you need to have resources to implement this and any number of other regulatory requirements.
I’m curious, what does Apple use Rust for?
The choice of speed seems consciously intended to make it seem more frantic than it is. It's too fast to make out what's going on. If they played it half speed, it would be closer to reality and also easier to see and understand, so why is it this fast?

What dangerous ideas would you say Scott Alexander has propagated?
I was very sick as a child: asthma, neurodermitis, a lot of allergies etc.

At one point when I was 8 or so I thought that it really sucks that I have to be careful about how, when and where to play, run etc. so I decided to ignore all my symptoms until they get too bad to ignore.

I also started to shower cold (or rather: end every shower cold). And i "taught myself" to sleep without a blanket. It really just feels weird, and after two or 3 times you are used to it.

I'm almost 30 now, i'm rather temperature-insensitive, which means than I have no problem going out in a t-shirt in winter, but also can do sports in the hot summer-sun. I also, on lab-tests still have all my allergies, but don't feel any of it.

It's very useful, and awesome what you can do with your mind :).
> [...] boots in under 2 minutes

Well, I thought about the usual end-consumer computers.

You can indeed shorten it to 1-2 minutes if you use a slick operating system (my servers usually have that boot time), and I've been told that you can tune most BSD and Linux systems to boot in 20-30 seconds.

However, this is still worse than even the worst mobile phones.
OAuth 2.0 is sooo simple, you don't need a library.

I implemented it with about 10 lines of PHP via CURL.

My twitter OAuth 1.x version for the same action is like 100 lines.
I enjoy my job. I work in a group in the RDBMS kernel. I'm very passionate about low systems-level C programming, so I think I'd be able to thrive in any environment that'd let me do it.

Development Environment: Everything is an "Eating our own dog food" type thing. Bug Database was built in-house and backed by an Oracle Database. Same story for the source control system (which, to my pleasant surprise, was a DVCS). Conferencing software and e-mail infrastructure is based on Oracle beehive

On the logistics side, quite a bit of bureacracy; Functional Specs, then design specs by certain deadlines. Significant changes need to get approval from maybe two levels of management. I only have about one meeting every two weeks, so that's a plus. The stress level is extremely low as releases are very very far apart, so unless we're dealing with a high priority customer bug, there's not much urgency to anything.
Publishers generally outsource the business of media duplication and have little or no capital investment in that. The cost of physical reproduction is a small fraction of the launch cost. The marginal cost of a 35mm movie screen print is about $1000. So if you open wide (on 3000 screeens across the US, say) and tack on a bit for promo stuff in each theater (posters, cardboard cutouts of the movie stars to stand in the lobby or whatever) it costs $3-5 million. By far the largest single expense of a launch is advertising, which is typically 50-95% of the production cost. And the largest component of production cost is salaries for big-name actors, which are typically derived from a rolling average of their recent pictures by regressive analysis, and negotiated from there - in other words, the point of having big stars is because of their proven ability to attract film consumers, so their participation serves an advertising as well as an artistic function.

90% of what publishers do is services and brokerage. Your imagination is not at all anchored in reality.
You could also just modulate the lambda used in the trellis quantization so that it is less aggressive in smooth blocks, and more aggressive in textured blocks. It's not as good as being able to change the quantizer, but you can get somewhere around half the benefits of real activity masking by changing lambda alone.
Absolutely, I'm not saying teachers are never useful or needed. I'd much rather have a conversation with someone familiar with a large codebase to get a feel for it than diving in and creating assumptions. But the bad advice is that a teacher of some form is essential, and that's wrong-headed, and it paralyzes people when asked instead to not just solve a well-rehearsed problem, but actually to discover the problem that needs solving.
This guy makes some interesting points... it would probably not be too hard to extend qwerly into that direction and make it very immediately useful... "meta-follow people across networks, with de-duplication"...
