I walk into the office of the VP of Business Development, interviewing for a role to lead their ecommerce team. And I sit down and notice a fidget spinner, a couple of fidget cubes and a scrambled Rubik's cube on his desk. As we are sitting down I casually ask if he's into puzzles, he says no, he spends a lot of time of the phone and is always looking to do something with his hands.

Anyway, 10 minutes later, his cell phone rings, presumably a family member, as he looks concerned and very politely asks if he can step out to take it, in case its an emergency. I say, "of course" and I'm just sitting there with nothing to do but stare at the wall.

I didn't want to take out my phone, so I grab the cube and start solving it.

He steps back into the office thanking me just as I'm putting his solved cube back on his desk.

Not the main reason, but I did get offered the job.
I think Qt does work well. Gtk isn't terrible either. WxWidgets, Iup, etc are also not bad. They just need either better cross language support (i.e. in C or with C iface) or better maintenance. I've had subpar performance with the more recently developed libui, but I have hopes there too.
If you're rapidly removing and adding, a simple fix for unordered_map is to add your own stack allocator. That way the memory you touch for it's lists is nearly always hot.

The same technique vastly improves map and set too.
No, C will be faster because you have more control, in the same way that Assembly will always be faster than C.

This whole article seems like it lacks any concrete message. In the end, it feels like the writer is still trying sell himself to me. Which... I don't understand; what is so different about "personal branding" on social media, and spamming me with emails about your life and ventures?

I disagree.

Being able to adapt to many business arenas is a skill. This can be applied to anything. eg The software dev that has spent the last 10 years doing Java, can still be outshined by a recent college grad who is able to adapt/learn quick and can produce more "creative" or effective outcomes.
Well, Mother Nature did not read the US constitution. We will realize it sooner or later in life.

Texas is also serious about keeping the cost of housing down. It helps that there’s a lot of land, but as the major cities are now boxed in by as much sprawl as people are willing to drive through (ala LA), they have lower barriers to densification and redevelopment compared to most places. Austin isn’t doing as well in that regard but the other cities have made it more of a priority.
Why not? How do you know?
Yes. My naive guess is, if this software was built more robustly, a supervisor would have read diagnostic message, restart the guidance system and try to recover from this situation as well as possible. Instead, the system was designed in a way it's not possible to spit anything out other than flight data.
We are not perfect and should have thought through this more. We created the script to be as non-intrusive and lightweight as possible. The number of incidents we saw were so minimal, we kept moving. We’ve obviously learned a lot from this and it will be 100% opt-in when we reintroduce it later.
If you sign up twice, won't they match your account and merge the results specifically to avoid this problem?

I think part of why they used twins is to say its two different people so they'd have to treat it different.

I'm actually curious how repeatable the results are. If they are using sampling of portions of the DNA (are they?) how much variability is there in a single dna sampling enun through the algorithm 10 times? Similarly for how much variability in 10 dna samples from the same person?
yes, but that severely limits your upside, and it’s harder to thread the needle (in both timing and pricing).
What I find most annoying that I'm never sure what to click in those "click all traffic lights" and similar puzzles. If there's a tiny part of a traffic light in a neighboring frame, does that count, should I highlight it?
I've done both and failed, and I've done both and succeeded, I haven't figured out a pattern yet.
No, you may consider the statement misleading, but it is correct. 100% of 4/1000 is 4/1000, 50% of 4/1000 is 2/1000, so 50% more likely than 4/1000 = 4/1000 + 2/1000 = 6/1000.
The source does not go into the abortion side other than that quote, and it's hard to judge what actually happens. There's a big difference between "your child is going to require 24/7 attention until they likely die before adulthood, we advise an abortion" and "your child is unlikely to survive childbirth but is healthy otherwise, we're going to abort the foetus against your will".

The only other source I can find from a brief Google is from a predominantly pro-life org.
I would need to see data before I believe that women entering the workforce resulted in higher home prices in a significant way. I have no proof, but I guess it allowed women to more accurately value themselves in the market, therefore helping them pair up with other high income men, and causing home prices to go up where dual high income households tend to congregate. But on the other end of the spectrum, women may have displaced men and caused pay for men to go down, thus total household income would not have risen as much. Even more, men and women on the lower end of income scale are less likely to marry, therefore would have even less purchasing power when (or if) buying a home.

Very interesting knowledge acquisition technique. Thank you for sharing.
I think a point here to consider is that you yourself call it a "media budget" and there are certainly demographics whose media budget goes to video games first and everything else second. Fortnite for being a "free" game is certainly eating interestingly large chunks of people's media budgets, especially when you also consider "knock on effects" like Twitch and Mixer subscriptions among some of the most invested in Fortnite.
> Yet the company continued to deny refunds to children, profiting from their confusion.

> Facebook often failed to send receipts for these purchases, and links on the company’s website to dispute charges frequently failed to work, according to court records.

So if you can't get a refund from Facebook, contact your financial institution and dispute the charges through them. There's no guarantee of success, but you probably have a better shot going that route.
I've been to Cuba many times over the last 10 years and have seen how pregnant women are treated up close and personal. The difference between Cuba and the U.S. is that Cuba has a greater sense of urgency when it comes to pregnancy. No one is coerced, but there is a community-driven sense of urgency and importance when it comes to following up with your pregnancy.
There is a limit, but some of the best people I've worked with have changed industries multiple times. There isn't only one way to do things.

Of course your diagnosis of this particular author is probably correct.
You can do that in a few minutes using an extension which allows you to inject custom JavaScript code (e.g. TamperMonkey for Chrome.)

This line should do the trick:

for (const node of document.querySelectorAll('.commtext')) {node.className = 'commtext c00'}

Being off by a few percent from nothing more than a cheek swab doesn't seem like a sham. I'm sure if they got a lot more sample to test from it could be made more accurate.

Have you looked at things like thermometers? They don't offer more than +- 2F accuracy for those under $100. Some meters, etc only offer +- 5% accuracy or worse. Those aren't shams.
Yeah this looks the same as Crane AI, and their ethics seem very questionable https://www.glassdoor.com/Reviews/Employee-Review-Crane-AI-R...
Because that wasnt what their reply was about?

I dont really get this style of steering a discussion: the idea that every reply needs to include a disclaimer about every differences and some insight into how the poster agrees or disagrees with those things as if checking a box. “Oh darn we cant villify the messenger now what are we going to do... well we can discredit them by highlighting why we cant question their stance on anything”
Indeed, standard library is often slow. Sometimes by orders of magnitude.

Here’s an example where a fast linked list implementation (not mine, `CAtlList` from ATL) approaches or outperforms std::vector: https://github.com/Const-me/CollectionMicrobench

Fortunately, in C++ we don’t pay for features we don’t use. If you want fast code, no need to go back to C, you only need better C++ containers.
I'm curious about those tartigrades. Will the scientists put them in the water and bring them back to life? As far as I know about tartigrades, once immersed in water, the body returns to a normal metabolic state over the course of a few hours, even though they died hundreds of years ago.
Tesla at least in the case of the model S, has quite respectable specifications, but I physically could not drive one a couple years back. IIRC, Like the newer mustangs the seat angle drives my knees into the dash at an angle which doesn't provide enough clearance to get my feet into position. ALSO IIRC, I had to lean the seat way back to keep my head off the ceiling. If I had one handy I would go measure why it doesn't work and compare it with their official head/legroom numbers.
> Americans measure it from conception

A pre-birth death can't be counted among the 'per live birth' deaths, and would have to include estimates of miscarriage rates since those are woefully underreported everywhere. Pretty sure every country starts the clock at birth.
Reading between the lines, it sounds like it's going to be mainly redistributing income from hydro-power generation sold to the rest of the country, which makes it sound similar to things like the Alaska Permanent Fund (i.e. a dividend paid from exceptional resource revenues which is below local subsistence levels rather than a taxpayer-funded redistribution programme)

Some Indian sources (which also don't seem to have a figure_ suggest they're also proposing top up the fund by cutting other subsidy programmes, so it'd also be interesting to see the net impact on different sections of society if it happens

Personally, I think this is bad advice, because without an undergrad+ background, the projects above will either be impossibly frustrating or you will make up some crackpot bullshit. Plus, the undergraduate curriculum is its own reward.
> What does this have to do with C++?

Given that most new C++ features in the "modern day" are implemented as std::whatever, in the "everything is a library" way, it's extremely relevant.
This was probably very embarrassing and I'm sorry, but I laughed really hard at the thought of this. Thanks for making a smile this morning.
Because it was clearly bait meant to rile up Evangelicals in the US. Abortions due to fetal abnormalities are just and humane.
There's also Clickhouse [1] which seems to scale much better than Druid, and has similar architectural decisions to make it somewhat general as a columnar store for OLAP uses. Cloudflare wrote an article in the past where they compared Clickhouse and Druid and they chose Clickhouse because they could get similar performance on the same workload with 9 nodes in Clickhouse which would require hundreds for Druid. They built all of the DNS analytics at CloudFlare on Clickhouse [2].

Disclosure: I work at Percona, and we've seen a lot of our customers make use of Clickhouse and have begun some of our own services work around it in Consulting. It's now a primary database talked about at our conferences, and we post about it regularly. [3]

Ah, awesome - Inkscape has got me out of more than a few holes in the past few years, but it's always been juust crashy enough that I haven't truly felt comfortable pushing it at work, so increased stability is definitely welcome! :-)
I've been catching up with things I've missed, already forgot or never learned in school with Paul's Online Notes: http://tutorial.math.lamar.edu/

It's an incredible resource with great introductions to each topic and examples that are easy to follow and try for yourself.
Techniques used to read DNA only read short segments, from which larger segments are inferred.

Not surprisingly, the results are not reliable.

Feed the unreliable result into any classification algorithm, and you still get unreliably results (actually I was expecting worse)

Not only that, but you only read small parts- SNPs. So there is no bijection; just a rough correspondence. On the bright side, it's good for privacy.
Their reply was about normalizing the Cuban government's behavior towards pregnant women.

> Acting like this is coersion is disingenuous

This is a quote from the person I was responding to. If you don't understand how this is trying to normalize the behavior of a government there is no way I will convince you.
Surely there was an equivalent of a black box on the spacecraft right? Just a hunch I don’t actually know

I suspect there must be a secret majority of capitalist-apologists lurking on Hacker News because every time I open a thread, the top comment is defending one of these corporations.

I grew up and lived in Seattle. I left because of Amazon. My rent spiked, Capital Hill's cultural landscape that raised me was bought out and appropriated for the new influx of tech workers who couldn't care or know the musical miracle of what they had plundered.

I live and breathe computing systems and I want less of me wherever I go. Our effect when we enter local ecologies is stultifying, ruining, yet is celebrated as progress by some nebulous measure none of us can touch or taste or feel except for the wealthy.

With Amazon's entrance came foreign Chinese investment to buy out family run businesses like Mama's Mexican Kitchen. My aunt worked at Mama's for more than a decade. She was a fixture: articles were written up on her special brand of caustic wit she brought to every table. The Chinese investors bought out the whole block to convert Mama's and other neighboring cultural waystations into soulless high rises for the likes of me.
As for bounties, I think it messes up with the OSS governance model. Let's say there's a bounty for feature X. You implement the feature, want to merge it in, but the maintainers don't like it and don't want to merge it. Now what?
That doesn't make it a sham.
I recently introduced similar patterns in a few things I work on. The speedup I got over having to manage tons of small allocations surprised me a little.
How SamKnows Used Cloudflare Workers
Exactly that. Move fast, break things, and pretend it's a good thing.

Obviously not an SV-only thing, but the culture in SV glorifies it instead of making it something you should be ashamed of.
it’s not the cost really. although it will easily balloon to 5x the cost (initial overrun plus maintenance) it’s still too small to care about. the shutdown has probably already cost more than the nominal wall cost.

the problem is it’s a symbolic, umm symbol that is hard to walk back from.

another problem with your argument is that it’s blame shifting.
They didnt address it at all. They added an addendum distinctly about a US policy.

Your concern is that they were normalizing something that they didnt even talk about, solely because it didnt join in villifying Cuba just so you would continue reading. I dont really get that train of thought
This blog post says they are working on more full width and responsive pages, so maybe one day they'll get rid of the need for a separate "Mobile version".
same here. I really want to learn more about my past and also learn about my DNA (and all there is to learn with that data), but the invasion of privacy by such companies is just unacceptable (hence my refusal to take such tests).
I'd be surprised, to be honest. Tesco and other conventional supermarkets have been doing this for decades, and they already have a more distributed logistics network (while many internet deliveries are serviced from 'dark stores' which exist just to do that, some are services from actual supermarkets!). Amazon has a lot of catching up to do.

I do think it may be a slightly different question in the US; most US cities are much less dense than your average European city, which will presumably change things a bit. I don't see Amazon taking over the market in Europe, though.
Reasons Why Your Ecommerce Website Isn’t Selling Enough
I work with the smoothieware project (hardware QA). It is an opensource motion control firmware and openhardware control board which works with 3d printers, lasers, mills, etc. Initially based on GRBL and runs on ARM (LPC1769).

The openhardware scene has advanced quite nicely in the last 5 years. There are many very nice projects out there to build from which are largely able to be built at home with parts which can be made locally and/or purchased online. Openbuilds is a good place to start if you are interested.

I always try to remind people...whether it is 3d printers, mills, lasers...the knowledge gain from building/breaking/rebuilding your machine far outweighs the small gain you get from simply operating one. I have never printed an object as interesting to me as it was to create and design an entire working machine from scratch.

If anyone is interested in openhardware projects I recommend checking out reprap.org , smoothieware.org , openbuilds.com as well as several other projects which I am sure you will stumble upon through research on those sites.

There are many opensource CAD/CAM software packages out there which allow you to pick and choose what you like. I personally use Fusion360 for most of my CAD/CAM stuff (I know...not Opensource) and for 3d printing my personal favorite is Slic3r.
I didn't realize the value of this until after I was done with my undergraduate studies.

Textbooks and lectures will teach you what math is. The concepts, the different proof methods can all come from a book.

The value from an instructor is that they'll give you feedback on the _how_ of math. A halfway decent professor will edit your proof just like an English professor will -- from the level of word choice all the way to the method you constructed and presented your argument. And, just as importantly, they'll tell you when you fucked up and didn't notice.
A nicely tuned generational GC should end up with first and second generations effectively as arena allocators that get recycled very cheaply. When the time comes around to collect the second generation, it should have almost no live data, as it will only be filled with whatever was in flight across all the times the first generation was collected.

When I understood this, it was an aha! moment for GC languages in stateless server contexts. I could see that for a properly written server - ideally keeping any long-lived mutable memory like caches off-heap - GC overhead could be negligible.
You don't? I love finding new and interesting repositories. Maybe it's a tool that I end up using, maybe I learn something from reading it, maybe it's just a fun oddity that I can share with friends. I love seeing what other people are doing and getting inspired to work on more interesting things myself.
There is an interesting rant from Gian-Carlo Rota on why lattices are so rarely taught despite being so ubiquitous. I include them based on the amount of use I have gotten out of them over the years. For example, the entire theoretical structure of eventual consistency is "make your merge operation the meet of a semilattice."

Interesting how the Navy blames the sailors for the accident, but they couldn't even find someone to fill this position that's seemingly so necessary to avoid accidents like this in the first place.

It reminds me of companies failing in the marketplace and blaming their employees instead of their upper management.
Politifact is a trustworthy source, if you want to argue that they are being disingenuous find a source that proves them wrong.
For me this principle is also what often causes performance issues, because for many advanced features this leads to convoluted language semantics and sub-optimal implementations.
Their results seem well within the margin of error I'd expect out of a $100 DNA sequencing service. It's incredible that this kind of thing is now available at this price point.
I strongly disagree actually. I think mathematics is the best field to self-study. There is nothing in mathematics that cannot be explained on the paper. There are many textbooks that are very good that in most universities professors won't be that good anyway. I went to UC Berkeley to study mathematics (ended up studying CS though) which is supposed to be a top department, but most of my textbooks were better teachers than my professors. I still prefer reading textbook to people explaining me math. I don't even think I understand math when people explain me. I need to first teach it to myself. Then occasionally people offering different perspectives is very beneficial, which, again, can be done on paper.

I don't think you need a PhD level educator. You need mathematical maturity. Mathematics follows a very specific logical structure that needs you to shift the way you think. Human brain simply doesn't work the way mathematics needs it to work. But this is a constant time overhead. Once you understand how to approach mathematical problems, I can't see why you cannot learn everything from a textbook.
Unless of course you don’t know that Flutter exists but are very much working in that problem space.
>>Can we base our universal healthcare proposals on countries >>that have done it without the authoritarianism and human >>rights violations please?

You're entirely correct there are many other examples of western democracies that can stand as models. However, I believe the reason Cuba was chosen was precisely to elicit a reaction. A story comparing mortality rates in the US to those in Canada, the UK or France would have fallen by the wayside. For one reason or another, the mention of Cuba generates attention and reactions - as attested to by this post itself.
