Why? From the company's perspective it makes sense to ask if an applicant has a criminal record. Statistically someone with a prior conviction is much more likely to commit a future crime
> would you get into an Uber if you knew the driver had 5 previous DUIs?

Yes, unless they smelled of alcohol, but at that point the DUIs are moot anyway.
Legally Tesla's "autopilot" is considered a new safety feature like air bags were when they are introduced or such and is regulated as such. If they were considered (or advertised as) self driving cars you couldn't use them throughout the US. And honestly Tesla's aren't self-driving cars despite playing them on TV and don't belong in the same category as Uber, which seems to have just gotten a regulatory death sentence on their self-driving car project.

Just work on your passive income generation, few hundred thousands per year would be enough for most people....

Once you have your FY money, you'll see that retirement is overrated... and I have a lot of hobbies + plans to travel with my wife when the kids are out of the house (hopefully in the next few years), but besides all that, every year I am postponing my retirement, because I just cannot leave the team I am managing... so maybe next year :-)
In case this wasn't clear: they're not saying you won't generate a model from their Dvorak typing, but rather that the model you generate is likely to depend on the keyboard layout, and so will break if they try to log in from a different keyboard.
Are you referring to animals (including, under the right conditions, humans) seeing the polarization of light?

That allows them to figure out the position of the Sun when it is not visible due to clouds, which is indeed useful for navigating.

But what this article is about is seeing the Earth's magnetic field.

At least some migratory birds are able to detect both their longitude and latitude [1] [2], which requires more than just knowing where the Sun is.

Humans have been able to figure out latitude for a very long time...at least as far back as the ancient Greeks, and probably much farther back.

Longitude, on the other hand, eluded us until we were able to make reasonably accurate clocks. For sea navigation, that wasn't until the 18th century, long after we had compasses and knew about polarized light.

Boycotting ACS seems like a nice idea, but it would be challenging for professional chemists.
It also depends on the languages you already speak.

Swedish/Norwegian/Danish do not really have "little grammar", but for an English speaker, there probably won't be any need to explicitly learn the grammar, since it works mostly like English. But on the flipside, they are just as difficult as English for speakers of unrelated languages.

>That's the problem isn't it? A language is assumed to be a dialect of another language just because it uses the same script, regardless of its origins or how mutually intelligible it is.

Is that really the reason? Does it follow then that Vietnamese is a Chinese dialect before it adopted a modified Latin script?

I think origins does matter, apart from shared script.
The hardware processes to fabricate a thin phone are complex. Sure, manufacturers do it every day, but if you are a new entrant starting out with a pick and place machine and an OLED screen, you can expect to spend a few years replicating those processes and a couple million bucks on specialized machinery - just for the QA process. So, a big difference to if you just want to do a board.

The SQ3R Reading Method and Studylockr
You may have heard of SQ3R before as an effective way to absorb and retain information from textbooks: https://en.wikipedia.org/wiki/SQ3R

I am a software dev and do a lot of reading, and would find myself reading through 3 or 4 books, only to look back and realise that I only really remembered a fraction of what I had read.

I started using the SQ3R method and found it to be quite beneficial regarding structuring my learning, learning with intention, comprehension of the material and general recall. I used it for software development textbooks, video courses and blog series.

My problem was that I had all my notes in Google Docs, my reminders set up in Asana, and either a physical book in front of me on the table, an e-book on the Kindle or in yet another window on my computer, or some web page open in my browser on another tab.

It was all getting a bit much for me, so I decided to build a web app that would make my notes a little more structured, would take care of the reminders for reviewing past material and to continue through unfinished material.

It's called [Studylockr](https://studylockr.com).

It was released today to public beta in order to get some real user feedback. Suggestions on additional learning methods (other than SQ3R), feature requests, bug reports, areas of confusion, general grumbling and any praise would be greatly received.

I'd really like the app to turn into a resource for students and lifelong learners, people wishing to change career, people on-boarding at a new company and wishing to get up to speed quickly, experts needing to stay abreast of developments in their field - basically anyone with an interest in learning and personal development.

Best of all, it's free! After adding way more features and making a buttload of improvements based on user feedback, I may turn it into a freemium product, but for now I just want it to be useful to people.
I'm in much the same boat: Planck with the Workman layout (laptop and desktop), laptop keyboard with both Workman (touch typing) and qwerty (very much not touch typing), and on-screen on my phone.

Even just swapping between the staggered and grid layouts, both Workman, changes how I type in a way that I'm reasonably confident would affect the accuracy of this service.
I've used Duolingo for about a year now.

This is what I discovered:

1) It can't be your one learning source. You get the essence of the language but you'll never become fluent.

2) It's very good at keeping you engaged. It gets an A from me on that.

3) The web app is stricter and will force you to learn better than the Android app

4)On the Android app you can get thru the challenges without learning a thing. You can just guess.

5)Your mindset should be to learn as opposed to getting thru the challenges.

6)Grammar is important so make sure you read the text they post on the web app. The phone app does not have it.

7)Find someone to speak the language with you ASAP. Speaking is the fastest way to fluency.

8)They've started to monetize the app so ads are a problem now. And ad-free is expensive.

9) It's many times better than the in-class teaching I got in junior high. They should replace the 1st few semesters with the app.
I'm sure what they admitted was true, but they left out information as well. They should release the entire set of logs for the crash, for transparency.
I think one of the biggest factors is that they run their own registration. A lot of the little countries outsource their registration to american companies such as verisign. ISNIC says they will only take down a domain on order of an Icelandic court.
Ah, that was you:) I just noticed those negative values were being allowed. Thanks for doing that I'll fix that up. I need more validation for sure.

With the $ display I thought since the default on posting is US$ that it would be more obvious to mean USD by default in the display. I can easily change that to be US$ instead or something more uniform. I was also planning on making a converter per currency display to show real market value conversions to any currency.

What currency format would you think people would prefer? I could straight up do symbols and all?

Hopsworks – A REST API for Hops Hadoop
Agreed.

I carry the personal view that when someone says "text editor" they are implicitly implying plain text. As such the leading paragraph of the article makes me twinge a little when "text editor" is used rather than "word processor".

The article then continues on to describe the editor which sounds very much like a WYSIWYG editor. Indeed ProseMirror[1] homepage says the following.

ProseMirror tries to bridge the gap between Markdown text editing and
classical WYSIWYG editors.

It does this by implementing a WYSIWYG-style editing interface for
documents more constrained and structured than plain HTML

So whilst I've made a point of it reading oddly (and I would have thought this would also be the view of most others on HN) I am not trying to disparage the authors use of the term "text editor". But rather I am curious as to why such nomenclature happened to be used here as I seldom see it outside of descriptions of things such as Vim and Emacs.

Fun fact, some of the best "italian" pizzeria's in NYC are actually owned and/or run by Albanians.

There is a whole generation of Albanians that moved in Italy (after the 90s), learned the trade there and eventually moved in NYC and opened their places.

Fun fact number 2: A lot of greek places in NYC are actually operated by albanians. (for the same reasons as above).

The main reason is marketing: People in the US know italian and greek food very well, but they are not familiar with Albanian food (which is just as good), so it is much easier for Albanians to market/open a italian/greek restaurant.
The name "PowerHammer" is also a bit of a mismatch. It's basically a covert channel via power consumption, which has been known. The transmission mechanism (write) is to idle the CPU for specific intervals of time in order to transmit bits.

Impressive engineering, impressive bitrate, but not so novel an idea, overall.
They might have deduced it from other data they have obtained legitimately, but as it's still data about you they have, they should tell you it and if it's incorrect you should be able to ask them to delete it.
High pixel density of modern screens makes it very difficult to reconstruct the signal. That, combined with the fact that LCD displays are far less susceptible than CRT displays, makes it virtually irrelevant for many new displays. Exceptions may include TVs, which use much more power per pixel, and lower-resolution screens like those on netbooks, though now that even phones have >1080p screens these are much less common.

That is not true, at least for CMS. All the RAW data taken in pp collisions during 2011 and 2012 - ie the Higgs boson discovery dataset - has been saved in tape. As a general rule, we never delete RAW collision data that actually make it into permanent storage. Of course, data that didn't pass the real-time selection to be recorded in the first place is irrevocably lost.

> What’s the point of learning Chinese or any other script language if you don’t learn the script?

I once learned Chinese in a very intensive course that focused on the spoken language and only taught a few hundred characters. It has proven very useful for my occasional travels in China, being able to interact with hotels etc., having nice enjoyable conversations with my drivers when hitchhiking, etc. For me, my present skills are enough for what I want to get out of the country; for me, China is just one country among many. The few characters I know are enough of a bare minimum to find my way around. If I were keen on reading Chinese literature, then I would definitely go further with characters, but there is value for many people in having simply a minimum command of the language.
I believe the original meaning is more like if there is an exception, there must be a rule (otherwise it wouldn't _be_ an exception/you wouldn't need an exception). It's been watered down a lot, and is often used to suggest that any counterexample makes a rule stronger (which is obviously not always the case -- enough counterexamples just proves the rule is wrong/doesn't exist).
Tae Kim's Guide to Learning Japanese is what I used when I was starting out. Iirc it's pretty focused on grammar without a lot of fluff or a specific program, but if you already have a decent grip on grammar generally and like learning in terms of rules and patterns it's excellent.

> I looked at it, but that doesn't actually tell me the touchscreen interface. It just tells me the bits they're currently using.

I have to agree with you on this. This is not a full hardware specification, it just tells how the hardware should behave up until the driver was released.

Modern open source hardware is still far in the future.
In a binary heap, there's a single root, but after that, there are pairs of nodes. In your case, the item has the same size of a cache line, so things are not too bad. During traversal, you'll always read two whole lines for each pair of nodes. You could still worry about the CPU cache's n-way associativity, but either that requires a lot of control over memory allocation layout or it will provide diminishing returns.

Anyway, the interesting case is when items are smaller than a line. Look at an array-based implementation of a heap:

https://en.m.wikipedia.org/wiki/Binary_heap#Heap_implementat...

Root is item 0. Assume it's aligned to a multiple of 64 bytes and you have two 32-byte items per line. When comparing array items 1&2, 3&4, 6&7, etc., notice how the two items are always in different cache lines. Item 1 is in the same line as item 0, not item 2. You're always crossing the line boundary. If the root were at item 1 in the same array (or, equivalently, item 0 in case the array started at a multiple of 64, plus an offset of 32), then each pair would be always in the same cache line.

In case it wasn't clear, I was pointing out a similar phenomenon with other data structures; it wasn't about linked lists.
> And as I've already told you, those statistics aren't remotely relevant to this discussion.

No you didn't. I posted those figures exactly once in this comment: https://news.ycombinator.com/item?id=16585982

Not had previous discussions with you. Exactly one, the previous one which you did not reply to.

I literally spent the last 2 weeks looking into this. Used Confluence and a few wiki solutions before. Both in context of a tech team in a large investment banking institution, startups and community organizations. In the end it was a close call between Confluence and a new product called Slab, for my small startup but we decided to go with Slab (http://slab.com).

What I liked about Slab is the way better performance over the Confluence, quick integrations from their team (took them about 2 days to add draw.io integration on request). I liked how clean it was and easy for non-devs in my team to understand the structure.

I'm assuming your wife was treated with Lemtrada? That was a unique circumstance.

The drug was originally priced for cancer and required a high dose. Better drugs came out, so they repurposed it for MS, but at a much lower dose.

As such, they repriced it and give it away for free for cancer.

Not sure why your bill was $450,000. Most MS drugs run around $60-90K per year.
> As noted in the article, the information being released includes blaming the victim and other PR spin. This doesn't serve the public or further highway safety; it further's Tesla's commercial goals.

I disagree. People need to know that autopilot doesn't eliminate their responsibility for safely driving the vehicle and paying attention. People need to know they HAVE to respect the autopilot warnings. If that is happening too much in an area and so is too cumbersome, then don't use autopilot. And to wait a year for that to be released would not be in the public interest. Neither would a year of unanswered BS from short interests and competitors, considering that Tesla's vehicles overall are incredibly safe.

I think NTSB's action to remove Tesla is fine. Tesla felt they had to release such information (and there's a good argument for that, IMHO), but that is against NTSB's policy as it could compromise the investigation. So be it. Removing them may be best for all.
2 questions:

1) A friend of mine recently broke his arm. His typing profile is going to be quite different from normal until he's fully healed. What do you do in this case? Is there a "reset my typing profile" thing you can do?

2) This seems vulnerable to replay attacks in a way that hardware-based 2FA systems aren't. How does this system prevent that?
Awesome, but will there be a market now fully re-useable rockets are becoming a thing?

Also the bits supporting the engine (ie the fucking spaceship) is not mentioned anywhere, if they are going to fly this thing in 2020 (!!) making an airframe for this which has to fly 5-10 times as fast as concorde and stores hydrogen/oxygen is not going to be a walk in the park in terms of engineering.

Graal started as Project Maxime on Sun Research labs, back in 2005.

Oracle kept Sun Research labs, Maxime eventually became Graal, absorbed lots of PhD work specially from the Linz university, and became integrated into the official JDK in 2018, 13 years later.

The opening line of Project Metropolis, was how Java should look like in the next 20 years, and lets be honest it remains to be seem how long Oracle will be committed to it.

I know you are aware of all this, given the very good comment you posted, but I guess the big question is if Microsoft is also willing to spend the same amount of money into, lets say, using .NET Native to rewrite the CLR in C#.
There is actually a semi-official categorization that Tesla seems to ignore

https://www.wikiwand.com/en/Autonomous_car#/Levels_of_drivin...

pilots are level 3 upwards according to this classification. Level 2 systems are called assistants. If tesla would adhere to the industry agreement, they would call their system an "assistant" and not a pilot.
I think the problem is the "bad" things I may or may not have done in the past is none of the potential employers business.

Not even when pages are resident in memory. I mean after it gets going, ignoring the initial latency of access, which is indeed staggering by CPU standards. To dramatically slow down memory access it’s enough to just miss the cache every time. Here’s another thing most people don’t know: missing cache results in at least 100-200 cycles of delay to fetch from main RAM. People don’t quite get how long that is. A good demonstration is to count aloud to 200. And then realize that if it was L1 hit, you’d be doing several operations simultaneously per every single count. As CPU frequencies increase, this number trends upward. All of a sudden your ~26GB/s of memory bandwidth turns into a pumpkin.
