From a protocol level, NVMe is actually designed for SSDs - just look at the amount of queues it has https://en.wikipedia.org/wiki/NVM_Express#cite_ref-ahci-nvme.... To really take advantage of this, you'd need your filesystem to be designed for many independent IO streams. ZFS metaslabs probably help, but I'm sure there is more you can do in this area.

On the other hand, I don't think many people would be hitting any limits where this matters.

The way to solve this is just for companies to give out their API in a public manner. You'll almost never be able to secure it from scrapers.

We experienced this at Honeywell, when I first started here we were blocking users that scraped the app instead of giving them public access and teach them how to use it correctly.
I predict intimidation tactics via social media are going to start going the other way ... activists targeting not just corporations, but their managers and executives, doxxing them, ridiculing them, and using other types of public pressure to influence their employers' policies and goals.

Google hasn't even released a complete PR demo of their cars, just a few sporadic shots of one of their Koala cars driving around with a blind guy in the driver's seat. The only tangible data that's been released from them is last year's California DMV disengagement reports, which Waymo reported 1 unplanned disengagement for every 5000 miles of testing. But they were driving around downtown SF back in 2011, most of what they've been up to in the meantime is validating their software to the safety and reliability standards they need to be at before this technology can be foisted on the public. They were ready to start moving folks around Mountainview, totally driverless, back in 2015 with their Koala cars but DMV regs put the kibosh on that.
A write-focussed SLOG device can massively improve your write IOPS though, and is massively cheaper than having an "all-ssd" pool, while being able to approach it's normal use performance. If you have a sustained heavy I/O load, sure - going full SSD will be your best bet, but for most usecases, you only need peak IOPS performance in short bursts.
I use my debit card all the time. It's been stolen (cloned?) once; my credit union called when they detected it, and we went through the recent transactions and reversed the fraudulent ones.

In case the thief really does manage to "clean out" my checking, I usually keep most of my money in savings and only transfer back when necessary. Savings could probably be cleaned out too if someone has my PIN, but if one's just using it for credit transactions, then at least most of my money's safe.

That all said, I still do take a lot of precautions with my card. Namely: I only use it at places that I trust. Everywhere else, I use cash.

I have the 1541 Ultimate II cartridge for my C64 and it is a fantastic unit. But the C64 itself is getting on and I wonder how much longer it will last. This is very exciting!

Does it resolve the C64 Chroma/Luminance interference issue? I would love to get a real hardware implementation of the C64 without the interference flaw and see it on a modern display without the horror colour bleed.

I also vaguely remember reading a guide on how to solve the problem on an original C64 with some modification, but I simply cannot find the page anymore. Does anyone have any info on this?

Raid is for convinience and performance. It is not and cannot replace backup. In any case, if you want safety, RAID1 is the way forward, and not RAID6. An 8 drive RAID6 with 8TB WD Red NAS drives (URE <1 in 10^14) is virtually guranteed to have at least one read error during a rebuild (if the URE rate is true, which I believe it is not).

Regardless, the determining factor here is how much data do you need to read in the case of a failure to rebuild the array. RAID1 wins every single time because you cannot read less than the single drive you need to replace.

> it's just so much you have to think about

Like everything else (including riding a bike), this is true of the beginner, and relegated to your subconscious after a few dozen hours. It all just becomes automatic.

I drove past half a dozen stop signs, hundreds of cars, several traffic lights, four different speed zones, and made a cross-traffic turn, and was thinking about testing code this morning.

You can pay attention without having to actively think about what you're doing, just requires making it a habit.

The nice thing about doing it like this is that the file persists on disk so viewing a page is decoupled from fetching it (which is nice for a lot of reasons.)
Adding legal agreements into a technical standard is tricky. Security researchers absolutely need protection, but it should be addressed at via legislation. There needs to be a clear way to distinguish security research from malicious hacking that applies across technologies.
Tim Berners-Lee's position looks worse from that perspective. If he truly had no power to change or even influence the outcome, why would he take a position of compromise on his core values?

For a comparison, take Richard Stallman's stance on not owning/carrying a cellphone. His position clearly does not influence telco policy, nor gov't policy on surveillance law. He has even stated publicly that it is a symbolic action and that he depends on the ability of others around him to make urgent calls if necessary. Yet he still takes the symbolic action. Why? Because standing up for one's principles is important, even in the face of a large inconvenience (or even dependence in this case on others).

Berners-Lee would suffer essentially zero inconvenience from taking a principled stance in the face of much larger corporate players who in reality determine W3C policy. His only hit would be to his ego, since it would reveal that his stance is largely symbolic rather than being a real player in the W3C.

I can certainly understand his stance given the prominence of such compromises in the tech industry. But I certainly do not agree with it, and I find it likely that history will not honor it as a principled stance.
This makes me really sad. DBC changed my life dramatically. I wasn't a fan of some of the changes/decisions they made over the last few years, but I would be in a much, much worse place overall without DBC.
You can get a disaggregated version of what ZFS does - you can have filesystem -> LVM -> MD -> devices, where the MD layer does the checksumming at a sequence-of-bits level. It tends to work less well than ZFS though; snapshots are a lot more efficient if the low level knows which bits are which files at the high level, scrubbing can be done more efficiently if you know which files are in use and which aren't, if the parity checking wants to use idle bandwidth then it needs to know about user-requested access. Perhaps most importantly, data writes need to be async for performance, but filesystem metadata needs to be written in a way that will maintain the filesystem's invariants, so the question of when bits hit the physical disk ends up being intimately entangled with the filesystem's internals. It's really difficult to express an interface between the filesystem layer and the parity layer that lets it do the right thing.
There goes yet another example of Goodwin's law in action, but I'm not so glad for the arguably rash, overly emotional, and definitely not balanced analogy.
He's trusting the lives of the drivers and passengers of all the other cars on the roads he drives on with his system test as well.
It's not about the number of edge cases, it's about the overall result. Airbags reduce variance in outcome. They hit a lot of people who would otherwise be unharmed in the fact with a small explosion in order to save a few lives in serious accidents.

The worst case is better and the average case is better because you've eliminated some outliers. However,the median is far worse. The group is effectively being punished to reduce the effect of the worst performing members.

An AI that drives into a partial lane obstruction is only better than no AI for a very small number of cases.

Cheap Baseball Jerseys – Quality at the Best Price
American tourists have an appalling reputation in most of the world, but I wouldn't take that as a reason not to visit America. Most of the stereotypes of Chinese tourists equally apply to Americans.

I think that in both cases, the causes are essentially the same - inexperience. American and Chinese people have very little vacation time. They're both big countries, so there's a lot to see and do domestically. It's quite normal for a European to have travelled abroad several times a year since childhood, but a very large proportion of American and Chinese tourists have little or no experience of international travel. A lack of experience and the desire to cram a lot into a short trip encourages large group tours, which are inherently more disruptive than independent travellers.

It's hard to be thoughtful and polite when you're being hustled from one Kodak moment to the next. It's hard to blend in with the locals when you're in a group of 30 foreign tourists. It's hard to pick up on the local etiquette when you've blasted through six countries in as many days; it's doubly hard when you're from an unusually extroverted culture.

Savvy Americans have started to leave the tour bus behind, learn the art of travel and buck the stereotypes. I'm sure that Chinese travellers will follow the same path.

As someone with a basic Comp Sci understanding of crypto currencies could someone explain to me why there is a scalability problem? I thought one of the primary benefits of Bitcoin was that higher transaction fees will attract more miners and ergo the transactions can be processed at a higher rate. Why won't this problem be resolved naturally? Tinkering with the block size makes sense to me as a way to crank through more transactions per mined block, but again, why is it even a problem? The mining power is just not there?

> I think parent's overall point is that the private sector has amassed quite a lot of power that could overstep / bypass the government entirely. It's not outside the realm of possibility that a team of rogue people in one or more social companies could literally trigger a war or worse.

Let's not kid ourselves - well before that happens there would be "Guys with guns" to see them which would stop all possible posturing.
Yes there are. That's the whole problem. It's complete chaos. There are several hundred people huddled in one area looking at one giant screen and there are several trains being called in sequence. How would you know that a given person was waiting for the 4:30pm Acela to Union Station to be called and not the 4:33pm Northeast Regional to Boston?

As somebody who commuted for a long time at peak rush hour back and forth from Penn Station to D.C., I can tell you that following people who "seem to know where they're going" would not be a reliable strategy.
If memory serves, Google runs a custom build of Ubuntu which they've never released--probably due to licensing with Canonical. My guess would be that the Linux Google Drive client may, too, have some restricted licensing. We do know they have one, however:

You can get pretty far with a secure element. Server challenges with signed payload of nonce + current timestamp, and client verifies it and then re-signs the payload. For something like a third-party coffee-ordering app, the economics of the usual attacks don't scale (either physically tearing apart the chip or exploiting a vulnerability in the first-party app).

You can use "disparate impact" doctrine to argue that just about anything is illegal. It's pretty hard to full proof yourself against that.

But there's a big difference between something that existing legal precedent has ruled as strongly likely to be illegal for hiring (IQ testing), and a currently widespread hiring practice that may at some future date suffer the same fate (hiring from particular schools). The legal risk of the former is extremely high, while you would have to be extraordinarily unlucky to suffer damages from the latter. Even if the courts do so rule in the future, you'd have to win (lose?) the lottery and be the one or two companies that get taken to court in that test case.
> DRM which is essentially encryption used with some sort of e-commerce system

I'd say this is incorrect. At it's core DRM requires a locked-down system, either on the hardware or software level, but always closed source, to hide operations from the owner of the device. Encryption is a big part of this but technically doesn't need to be.

I agree that content creators have the right to stop me from consuming their content if I don't pay money, watch ads or whatever, but they don't have the right to require me to install unknown software or hardware on my computer.

They booted paying passengers for crew members.

They argued that this would result into a cancelled flight the next morning if they wouldn't have flown the crew, since no crew would be available. This may, or may not be the case. But if it really was that urgent they could have chartered a private plance for the crew. At ~300 miles even renting a car may have been feasible (this may have cut into the mandatory rest period of the crew, though).

Another mistake made was allowing the passenger to board and then removing him

Precisely that! You just can't have paying passengers board a plane to then kick them out. If the flight is really oversold you should find volounteers at the gate and - if necessary - auction the bumping off. If nobody wants to be bumped for 800$ then raise the price. It's not my impression that they really did that. They just selected four passengers, stormed the plane and essentially told them "off!" When Dr. Dao refused (which I can understand, if you have patients potentially waiting for month to get to see the doctor) they gave him the "Nice face, would be a shame if something happens to it" treatment.

Oh, and offering the amount in cash and not in some vouchers, which probably come with so much fine print and restrictions to be virtually useless would probably help too.

Unofficial Hacker News Meetup Portland, OR
Attending Dev Bootcamp in March 2013 is the best decision I've ever made, it totally altered the trajectory of my career and I'm happier and more fulfilled as a result. I'm not sure I would have been able to make the switch from consulting to software engineering without DBC.

That being said, I'm extremely lucky to have enrolled during the narrow window I did. The entire bootcamp industry is suffering, not just DBC. They've now totally saturated the market with juniors and refused to adapt to that reality by extending and improving their product: they should be offering longer courses, covering more material, interspersing their offerings with internships, and providing intermediate-level bootcamps for engineers looking to graduate to the next level. Today's bootcamp graduates have to compensate for this themselves by continuing to teach themselves new content as they fight for jobs after graduation. This is difficult - don't get me wrong, it's still doable and still very much worth the effort - but it's hard, and this explains the current embarrassingly low rate of bootcamp graduates winning jobs as developers. If this describes you: keep your chin up, find a friend to practice interviewing with, and know that you're going to need to work through this material eventually: https://teachyourselfcs.com. And feel free to reach out to me.

I don't think anyone close to the bootcamp industry would see this as a surprise, and I think we'll see many more bootcamp closures/M&As in the near future. Hopefully the industry will evolve and adapt, not die - everyone deserves the opportunity, not just the lucky few who had it easy before the market got saturated.
Don't blame Tim for what we ALL have done to the Internet since three decades. This was the inevitable result of commercialisation.

The Internet has just become the latest arena where the age-old battle is playing out.

The URE rate is most likely much lower.

However, the chance of failure for a RAID6 of 100x10TB disks is less than 0.482% after 1'000'000 rebuilds.

RAID1 is space-inefficient, a 100x10TB RAID array might never fail but it has only 10TB of storage space.

A RAID10 Array has a 14% failure chance for just 4x2TB disks using 10^14 failure rates.

RAID1 and RAID10 are definitely not the way forward, it is less secure, something that should be immediately apparent if you read the link in my previous comment.

A 10 Disk RAID6 with 10TB disks is more reliably than a RAID10 by multiple orders of magnitude and more space efficient than a simple RAID1.
So excited to share a markdown-it plugin which let you generate a visualization chart using several lines code.

- The project homepage: https://markvis.js.org/
- You can have a try online: https://markvis-editor.js.org/
- Source code: https://github.com/geekplux/markvis

## Motivation

We often publish articles enriched with data, since data make them more convincing and easy to interpret. Hence, techniques that enable the embedding of visualization into texts are of great importance.

However, the most frequently used method now is to export charts as images, upload them into cloud, and then paste them into the editor. It is a tedious process from the perspective of a writer. Besides, image loading costs much more time than that of DOM elements, which leads to poor experience from the perspective of a reader.
Would you rather have a large chance of your car driving into something it couldn't detect and a slightly smaller chance of being seriously injured or the status quo? Keep in mind that the odds of being seriously injured in a car crash in one's lifetime are already fairly low. How many people do you know that were seriously injured in a vehicle crash?

Most of the safety of AI comes from it being implemented in vehicles that are already far safer than average.
A 2TB drive for 400 or 500 USD? Cheapest ok-ones (samsung EVO) I can find are 700 USD, and then we're not really talking about drives you might actually consider putting in a storage pool used to store critical data.
