One summer I was running a month long simulation for my PhD and decided to learn Chinese using an undergrad text I found. It had about 17 chapters with 50 new characters per chapter. Normally this would be a two semester course. Using spaced repetition, some books that helped to show the pictographic evolution, and color coding the tones, I was able to go through a chapter a day—granted it took about 14 hours a day. After a few weeks I could read write and speak about 1300 words/850 characters. Reading was the easiest, then, writing, then speaking. Listening was the hardest and one I always struggled with. I don’t have a great memory, but if you have the time, tools, and will it’s very manageable. Usually we lack the time for such an indulgence.
Actually that has never been the case.

Among other things, people buy Apple so that they won't be seen buying something more viable.
"Minority"?

More identity politics reporting. Yawn.

Where I'm from... white males with mustaches are the minority.
git didn't work with it (maybe it does now). But there has been native version control tools in Smalltalk. There was ENVY, and Squeak and Pharo has Monticello, Dolphin had something (can't remember its name).

git is great in many ways, especially how it lets multiple developers to work more effectively on the same code base. But native version control tools on Smalltalk, while they might not work as effectively for large groups of developers, has native support — it can support things like versioning at method level.

Rather than arguing Smalltalk is the best or that it is bad, I rather focus on what I think — it has many great features, it's just that it's so different that it can't ever be popular, at least not for the foreseeable future.

This is kind of true. However there are subsidies in the Netherlands for electric cars, and we pay 0 road tax for them too. That also contributes a lot.

My VW Sharan now costs almost EUR 2000/year in road tax. It also goes into the garage for semi-regular TDi engine issues (last time we had to have the ECR valve replaced which also incurred 5 hours of labour).

TCO of diesels these days is not pretty where I live.

> People say the industrial revolution was the game changer. It wasn't. It was oil.

Oil gave us a lot of qualitative improvements, but the game-changer was still the steam engine. A way of turning external energy into work, be it wood, coal or oil. With that figured out, we've quickly moved through increasingly energy-dense fuels.
Before the VW take-over they had what was probably the worst rust issues in the industry with the exception of Fiat.
I mean trade as an institution, not just sporadic interpersonal bartering and sharing; more like merchants, trade routes, and the like. Exchange is not unique to man; trade, as such, is.

Trade becomes more worthwhile when communities begin to specialise. When people are nomadic, they cross many lands, and can simply find what they want on the way (obsidian from the mountains, shells by the sea, berries, roots, and game in forests). When people begin to stay in one place, long distance travel for trade becomes more valuable. As soon as agriculture develops, we discover that obsidian shards from deposits in the Caucasus are found thousands of miles away in central Europe. You begin to have towns focusing on a specific resource, or serving a trade route as goods and people criss-cross the land (Jericho, among the earliest known cities, for example, was possibly involved in the trade of salt; few things can grow in the soil near it).
Something’s wrong with this site. I used Firefox Focus and tapped on the Pricing link at the bottom, but it kept going back to the homepage. I finally typed “/pricing” after the domain in the URL to get to the pricing page.
Yep. If I get a Model X I will want to do long trips with the kids in it. Probably including to the south of France at some point. I can't imagine how travel sick they'd get in the Model S's rear sets, and don't want to :)

For us the X is really the only full electric option.
Hmmm. That's quite the jump. Daily rainfall of 6.07" vs 1889 record of 1.76". But hey, just a fluke, no doubt. Or evidence for iffy reporting.

> SAN ANTONIO - Heavy rain caused flash flooding Monday night in northern Bexar County and extending into Comal County. Some areas had up to 9 inches of rain, and water rose on some roadways, including Interstate 10.

> Tuesday morning, the National Weather Service said via social media that parts of San Antonio had up to 6.07 inches of rain, which "smashes" the daily rainfall record of 1.76 inches from 1889.

> Over 9 inches of rain was observed around Stone Oak Parkway, and more than 8 inches between Shavano Park and Camp Bullis, according to the NWS website.

Facebook has "helped" more than enough already.
I really, really wanted their tech to be real. It could have been transformative. I've seen a lot of glee over their (well deserved) failure, but I'd much rather be celebrating their success.
Is there camera monitoring inside?
That's a shame. But hey, it doesn't take much solvent for one drop of blood!
No, it's over 300km (source: have actually drived that much on a charge).
It's an excellent car, can't imagine what a tesla has to offer over it (I don't care about 0-100km/h speed, ie. the zoe is quite fast enough, and the Zoe's range is suitable for my uses). I guess the build quality is also better with the Zoe, and it doesn't have a ridiculous giant touch screen in the center console.
Serious question, even if the answer is fairly obvious; What does the future hold for Elizabeth?

I mean, how will a person who has done that and basically become a digital leper, recover or work again in any meaningful way? Change her name, learn a new language and move to another country?
Jessica is already on my list, but she’d be the first to tell you she’s not sciency. :)
That's a general thing for safety critical real-time systems, not just avionics.
The big advantage of flashcards in Pleco is the integration with the whole app. If you use the Pleco Reader, you can add new cards directly from the Reader. You can also create cards from dictionary entries and during studying check other dictionaries for each card, play the audio etc.. Some people prefer Anki, but personally I would recommend the Pleco Flashcards for learning Chinese.
She's very ambitious but now most people have lost confidence in her, so she will be able to pursue meaningful goals but not with the help of many other people as before. Quite a pity, imagine charismatic people using their cunning to benefit the world instead.... what a place it would be.
how rigorous is your hiring process? What should one expect when applying the IT position you have listed?
Meanwhile in Canada, there are no EV rebates (in most provinces), and due to the depreciation of the dollar and Tesla's USD-based pricing, buying a new Model 3 is now only $400 less than the Model S was at launch four years ago.
With her connections, it's hard to imagine she wont be able to find a way to keep venturing into new businesses. It's not like everyone who commits fraud ends up behind bars or something either.
That’s engineering not science. Still a good suggestion though!
My memory was that Firefox had implemented a newer draft (or final version?) of the spec. Sniffing the UA to avoid providing broken stuff to people isn't exactly evil.
Most filesystems have a limit on the filename of one element, but many don't have a limit on the depth of directories or the total length of the full path to the file. Some operating systems do have a limit on the length of a fully qualified file name, but you may be able to avoid that by only using relative names.
I remember when this was what progressive web development (enhancement was the term) was. I still don't quite understand how it changed into meaning web workers and all the caching and background process stuff.
I used to be a regular user. I never paid because they never gave me a reason to, not because I didn't value it. I'm not going to go out of my way to figure out how to give them money when I'm already getting everything I need for free.
For the non US audience could you say what IRB means?
Brain power varies throughout the year, peaking in autumn
You're missing the point here. Whether or not I can recover my account is tangential to the real problem of them not allowing me to contact Support.

You might be happy with that, but most people aren't. The "contract" is: so long as I can prove who I am to a reasonable degree, give me access to my account.
It's true that it's not very much in fashion. I haven't used or heard it in decades. Might re-introduce it, though :)
When your approach to marketing is “My product will kill this other product”, you most likely are approaching it wrong.
Combining iterator blocks and async methods in C#
I hope I'm not becoming "that guy," but I feel like everyone is still missing the point on Theranos. Even if they hadn't defrauded investors, the company would never have had the impact they claim, because Theranos' entire finger-stick idea just doesn't fit into the lab industry.

I spent a bunch of years in labs, working for the tech companies that made the "state of the art machines" that did the actual testing. Theranos wasn't only competing with LabCorp and Quest, they were also competing with the testing machine companies like Beckman-Coulter, Roche, Siemens, Bio-Rad, and many others.

So many tests get ordered for a CMP (comprehensive metabolic panel, the most common battery of tests), that you would need like 30 finger sticks to get enough blood. Theranos never clarified if they could do 30 tests on 1 drop, or 1 test per drop. That little misdirect actually matters a lot to the patient who might have to get stuck 20+ times for all the things the doctor needs.

I'm quite familiar with the way the state of the art systems work. A modern system is already testing microliters of plasma (your blood goes through a centrifuge) per test. Comparing size of blood draws is misleading. The several tubes that get drawn are for logistical reasons that don't go away if you switch to finger-sticks. For example, the law requires that a lab keep some blood on hand for emergency re-testing if it turns out you have a critical level. Maybe a tech drops your sample. Maybe the machine has a problem right when it's doing your test (happens all the time, no reason it wouldn't happen with the Theranos instrument, had it existed). How many finger sticks are required to keep some extra on hand?

Theranos was also misleading about the test time, but that doesn't get mentioned either. They claimed 4-hour test time, but compared it to the 24-hour turn around time of a major lab like LabCorp. In reality, modern systems take 8-15 minutes for most tests, depending on what it is. Large molecules (hormones, etc) and whole-blood tests can take longer, sometimes up to 1.5 hours on older machines. Nothing approaching 4 hours, though. A 4 hours test time is atrociously long.

And after all that, you still need a doctor to look at the results. Let's say the dream happened, and we all started going to Walgreens to get Theranos tested. Even if we got 30+ tests on a single finger-stick drop, we'd still need to wait 24-72 hours for the doctor to look at the results and call us.

Maybe I'm beating a dead horse at this point, but I think from the very beginning, Theranos didn't have a serious business model. I also would like anyone on HN reading this, who's interested in the medlab space, to understand that there's a lot more going on than just testing on fingerpricks and fraud here.

If any of you out there actually do have a revolutionary one-drop testing device, don't try to partner with Walgreens and open your own labs. Just sell/lease it directly to doctors and hospitals.
Updates can be stored in the BIOS flash, so if you can program this you could theoretically update the microcode. The OS can also patch the microcode during boot.

The signature/encryption is still a problem, which might be why they are using older AMD K8 and K10 processors from 2007 which didn't have this security. Still, if the keys do leak out of AMD or Intel, this is a huge security hole.
After using what was essentially this technique to learn to read Japanese I'm not entirely convinced it is actually all that useful compared to just reading. I found myself spending so much time in anki that sometimes I wouldn't do real reading at all... And for what? So I would have a chance at being sort of familiar with a character when I came across it? So called "flashcard blindness" is also a real thing. Context is so important when learning, sometimes it was like I had to learn two words, the word I 'learned' in anki and the word in the wild. Even though they were obstinsably the same word somehow they couldn't connect.

If this technique did help at all I think the effect was mainly psychological. Looking at a page with a bunch of words you don't know is stressful and demoralizing. Even being able to think that you have seen a character somewhere without knowing what it means can be comforting. It sounds silly but any amount of stress can severely inhibit language acquisition. You might be better off meditating for 15 minutes... Or taking drugs

The only thing that seemed to be 100% effective was readimg content that I was completely engaged in. It didn't matter if said content was close to my skill level or way beyond my skill level. As long as I am sufficiently engaged it doesn't matter how many times I have to reference the dictionary or comb google for grammar explanations.
As the article suggests, if you search Google for German language pages with "Sitzfleisch" and "Merkel" you will get pages of links from the last few years using the term. It could be an example of "newspaper German" like people sometimes make fun of the Frankfurter Allgemeine for.
A comprehensive evaluation of third-party cookie policies
Yeah I never got this argument.

We know that present-day hunter-gatherer peoples have high infant mortality.

We know that hunter-gatherers need a lot of land per person, and so therefore need to control their population, without birth control.

Yes, agriculture and high population density brings different problems and diseases, but to argue that somehow those are worse is to ignore basic statistics.

I do get the mental health argument, but only if you accept a bunch of stuff about human mental health that isn't fun. For exactly the same reasons that veterans don't get PSTD or depression until they stop fighting, we're going through a process of de-traumatising developed populations. We don't really know what lies the other side, because we've never been in a prolonged multi-generational period of peace and plenty.

These results don't make any sense and I don't believe them.

The author is generating random strings of length 64. They then generate N random string and search for them. The probability of finding a match is effectively zero.

> Interestingly, up to about 75 elements, the vector actually outperforms both sets.

No way. The unordered_set will perform one hash, one lookup, and return false. That is not going to be slower than SEVENTY FIVE string comparisons.

Looking at the code I _think_ that randString() for each of the N search strings is included in the timing code. That, uh, is not good? Line 29: https://github.com/akshaynanavati/benchmarks/blob/master/ben...

I don't know how Google Benchmark works. So I wrote my own simple test. I could not find any combination of string length and num searches where a vector was faster than an unordered_set.

The 10 Commandments of Good Products
I don't believe in those rights either. They're just as artificial as copyright to me. Criminals and even the government itself violate property rights on a daily basis.

The low level concept that enables society's rules is violence and the threat of it.
That frustration is understandable if you have a great product (or at least a truly realistic big idea) and struggle to get traction with clients and investors. But if John Carreyrou's account is accurate, Theranos was in the opposite situation. Their 'idea' was just an unrealistic goal, and their product barely existed, even at the time they were rolling it out for use on actual patients. The one thing they were good at was persuading investors and clients to give them money.

It'd be pretty rare to say "cu-de-ferro" unless you were really trying to be contemptuous. Normally, people say "CDF", which AFAIK originally stood for "cabeça-de-ferro" (iron head). It's a pejorative slang for someone who gets high marks in school.

I've heard that "cu-de-ferro" is a homophobic misinterpretation of CDF ("cu" is a slang for anus, and "cu-de-ferro" is supposed to imply you had sex with the teacher to get said high mark). Never heard of it being used in the ass-in-seat sense.
Sure I know cow meat is beef. But what I find hard is knowing when 2/3/4 characters together mean a specific English word. So when trying to read something I find it hard to figure out when I should and shouldn’t combine characters. I’m struggling a bit to learn. Picking up speaking better for me.
12 Factor: Dev/prod parity for your database
I noticed with MetroPCS, when I download a Youtube video offline, it's very slow. However, if I turn on my Private Internet Access VPN, it's fast. This has been going on for at least two years; well before net neutrality was destroyed.

I'm no expert in this, but I feel that that's a relatively definitive proof that they're throttling it.
I recently read this book as well, and can highly recommend it. Bad Blood is investigative journalism at its finest.

(It wouldn't surprise me if we eventually get a film adaptation... but those are always worse if you read the book.)

The reporter, John Carreyrou, also caught backfire from Theranos. Especially his sources whom he did try to protect but were stalked by private investigators & lawyers.

Given that Theranos didn't have a product it is only good news that they're finally dissolving. Holmes and Balwani ruled with tyranny and compartmentalisation which created a toxic work environment, but that does not mean all the employees were ignorant or stupid or into the scam; many of the employees were highly skilled and intelligent. Those who did know they didn't have a product (or that it was some dirty hack based on a different product) were manipulated by Holmes and Balwani.

I saw someone mention psychopath. I'm unsure what exactly these two people are. Sociopath, psychopath, narcissist, whatever it is; it isn't pretty.

When I read the book I was regularly reminded by Brian Krebs' "Sources: Security Firm Norse Corp. Imploding" [1]. They also had no real product and used compartmentalisation. Also well written (though way briefer).

5 Things Extremely Prosperous Writers Do That Are Rarely Discussed
In my experience, most companies that use "github" (and not "git") cannot get much done if github is down.
I agree. That's why we have to change the status quo. However the proposal from the EU commission is step in a very wrong direction.
Google quietly bought Mastercard credit and debit card records
Wireless carriers had exemptions from Net Neutrality. The basis was that bandwidth was much more limited and they needed more flexibility to manage it.
It must be a prerequisite for this kind of hyperbole that the technology it describes does not exist yet. Nothing is infinitely repairable or upgradeable, and neither of those things are ever free.
Most likely a fabrication defect. Someone drilled a hole in a frame at wrong place during assembly, but to avoid reassebling the whole ship they just decided to quick-fix it using a glue-like substance. Obviously the fix did not stand for long.
Probably not during production.

The probability of this being sabotage is extremely low.

It's more likely someone fouled up and then didn't own up.
As a German I spent an abroad term in Canada, so here as a grain of salt the difference between German and the work ethic across the pond.

9am: I arrive in the lab at around, sit at my desk and set up my stuff. Unfortunately there was is one around to start the day with a coffee break.
10am: Canadian lab mates arrive, sit at their desks and go on facebook.
noon: After spending three hours reading papers, fitting curves to data, etc. I get hungry. I go to lunch with a Dutch person I met in the building a couple of weeks ago.
1.30pm: Back at my desks. Through the towers of take away junk on my lab mates desks, I can see they made some progress on facebook.
3pm: I try to convince some of my labmates to go for the coffee place within the building to have a short communal coffee break. Of course everyone is too busy and cannot socialize, except for the post-doc from india (who does not facebook)
3:45pm: Back at the desk, wrapping up the results of my day, my lab mates are still "working". Next morning, they will tell me they stayed till 8pm in the lab and how increadibly busy they are.

Granted, in between visiting facebook and skipping communal lunch- and coffee breaks, they got some work done and I don't claim I delivered more results in terms of research and learning "output".

Yet I think it summarizes my and the experience of other Germans quite well. In Germany there is much more focus on not working long-hours but spending the hours you work productively. A German workday of an office worker is limited to max. 10h per day by law and my employer follows that rule religiously. Many colleagues contractually have 35 h work weeks and working 40 h requires a permit from the worker's council. If you are sick, you stay at home on sick leave, you join your colleagues again when you are better. American colleagues working here for a year or so as part of their assignment quite often start out to send an email that they are sick and will work from home. If you are sick, why do you work? Your job now is to get better. Quite often, breaks for lunch or coffee are started and ended together. Only few people come into the office with half-liter coffee mugs to consume on their desks.

Obviously there are exceptions to the rule, and office cultures of individual companies may differ. My current company's culture is very German if you arrive before 8am, you might be welcomed with handshakes by your colleagues.
Anyone have a text link or tl;dr about the issue?
