Was mysql "ready for production" when google used it? facebook? Lol.

Storage engines are hard. I'm boggled that they recommend that you keep the old replica around for ten days. When we did the MMAPv1 migration to RocksDB at Parse, we kept at least one MMAP replica around for 6-9 months, as we worked through the integration of Mongo + rocksdb ... even though RocksDB the storage engine is powering fucking Facebook.

I get so fucking annoyed at the Hacker News armchair brigade that wants to talk shit about MongoDB, when they don't know a goddamn thing about databases -- or, from the looks of it, Facts About Stateful Services In General.

At least the Windows right-click menu doesn't obscure the main UI and is actually designed for third-parties to plug into. I agree that you should be able to turn it off, but adding something to the context menu is completely different than adding a large UI element over the main view of a Finder window.
I think I've seen a few of those, but what are your examples? Interested to know. I normally check carefully for cases where the software tells you its an option (adding itself to right click menu, or to startup menu). But don't remember coming across one where it does it silently. Would like to know of those.
A common failing I've noticed in complicated multi-symptom diagnoses like this disease is that doctors tend to treat each symptom individually instead of trying to connect the dots of all the symptoms. As a programmer used to debugging complicated systems it makes no sense, my first inclination when multiple things popup at the same time is to look for the underlying root cause.
Amex cards were once the clear winner in terms of rewards, perks and prestige. That hasn't been the case for several years. The SPG card discussed in the article--widely known as the most lucrative Amex--isn't nearly as valuable to me as, say, the newly introduced Chase Sapphire Reserve. Their flagship Platinum card used to be second to none for traveller perks. In the last decade Airline consolidation and competition with Airlines own co-branded cards has chipped away at the value of the Plat. You see things like amex being forced to build their own airport lounges, far from high-margin financial services..

That said, if you buy groceries for a family, I still haven't found a better card than their Blue Cash Preferred at 6% cashback.
Didn't you just rephrase the headline?

Something Deeply Wrong with Chemistry (2010)
The John Ringo approach, from "Citadel". A Chinese supplier cut corners on the gold plating of a contact and caused a major accident. The response:

"The supplier, Qua Tang Electronics, is blacklisted. Find every person associated, every member of the board, every senior officer, and blacklist any company they are associated with as well. With something like this, and the Chinese, there is no overkill. Be wildly unaimed in your fire. Nuke first, ask questions afterward. Make the pain as widespread as possible."
Looking for more, Paul. This from a Swiss news site says he had previously reported threats to the police, S3's data center was broken into and flooded with a fire hose, and that he remained in the hospital in serious condition with burns on his torso, arm, neck, and face, and would likely need transplants:

Just a nitpicky detail: This not about citizenship but actions happening in a certain country. A German citizen in, say, Sweden would not be subject to this German law while a Swedish citizen in Germany would.
The comment you replied to suggested that it's partly because of "the feedback loop of primarily seeing cases from people seeking highly expansive readings of patent law." That is, these judges constantly see patent cases that are looking for expansiveness, which means that their baseline for what's normal may be skewed, or they may be primed for expansiveness.
Since the CAPTCHAs trigger based on IP reputation, I assume they're trying to prevent things like automated forum spam, by default for everyone.

Well there's this infamous interaction which is shown to most U.S. officers during their training: https://www.youtube.com/watch?v=kOSELcrJ7Kw

Admittedly, the officer starts the interaction with a command rather than a cheery, "aright mate," but I'm not certain that would have changed the outcome. The murderer later said during questioning that he killed the officer, "because he let me."

There is a very different dynamic in the US with regard to authority compared to the UK. I do think that US police have become too militarized. In particular with regard to the military-style raids discussed in the original article. However, I'm not certain that US cops can simply assume the attitudes of British cops without wider cultural transformation in the country at large.

I think many people envision hallucinations as these grand visions - like an LSD trip or something. So, when they wonder, 'am I having hallucinations?' the answer to them is clearly no.

Hallucinations can be as minor as seeing unexpected movement out of one's peripheral vision. It's can be occasionally seeing shadows that initially appear to be something else. Because those types of things seem relatively minor, people tend to disregard them. But, they can be a signal of some neurological system acting abnormally.
Interesting how browsers react to it, on my phone (xiaomi mi note pro) in chrome it's stunning and smooth.
Another crappy patent troll case: someone started suing hdd manufacturers over acoustic management, claiming (maybe in truth) that they patented the algorithm that actually make the hdd head move silently when it is active.

The manufacturers proposed as settlement disable the feature being toggleable, and this was accepted.

The patent holder never got money, and people never stopped using his patent, they only made users unable to select if theg wanted silent mode or not.

A rrsult of this: WD has been for a while making low end WD Black and high end WD Blue with shared mechanics.

One model in particular, the WD Black 1TB is almost 100% identical to the blue version. Except it had acoustic management off, while blue had it on.

After noise complaints (people even returned hdds thinking it was broken) they made the black have it 100% identical to the blue... but as result despite being now silent, it is 30% slower, slow enough to cause buffer problems for musicians and video editors. (or to make megatexture problematic in id software games).

So in the end everyone lost. No money for troll, algorithm is still in use, but consumers now have problems to find the hdd they want (almost no manufacturer advertise the hdd is not silent... so if you need to buy a fast hdd, it is trial and error)
I'm not sure why people still use Dropbox besides inertia.

I mean, it's not even competitive on the pricing. 1 TB @ 9.99$/mo while Microsoft gives you the whole Office suite plus 1TB of OneDrive at less than that.
If anyone's interested, I just added the source to a CHIP-8/SCHIP emulator I wrote in Java/OpenGL (through LWJGL) waaay back in the day. It's got a unique rendering style (screenshot at repository) and a hack to try and smooth out the flicker from XOR rendering you get in the original.

https://github.com/westoncb/java-chip8-emulator

It might take a minute to get it set up with an old version of lwjgl, but at least the source is there for now. I'll try and get it working and commit the necessary lib files later today, but thought I'd at least make the source available for now.
Not sure I understand - changing absolute position also won't reflow parents/siblings, same as transform.

Is this true... millions? With only 80 million people in Germany, it seems like if copyright trolls were shaking down millions of people, it would more or less involve every single organization and household in the entire country.

I don't think we can really blame the Neanderthals for that. Killing animals was likely viewed differently due to its necessity then. Plus, a lot of the protests now are due to industrial practices and sustainability issues that didn't exist then.
If not Dropbox, what solution are others turning to?

I recently signed up for Sync.com, due to their prioritisation of security features and they seem like a good company. I have come across some minor bugs, but I sent these onto their customer support who were reasonably responsive. Even with these minor bugs I'm still happy with the trade-off to move off Dropbox.

I must admit the most difficult part was definitely the services I used that directly integrate with Dropbox, like 1Password syncing. So I also had to find solutions to not just Dropbox, but also third-party services that integrated. For 1Password, I signed up for their Account option where they handle the syncing for you at a cost of $2.99 per month. Again, another trade-off I was happy to make.
I'm not trying to critique the company's engineering, but the workloads and challenges they are facing are not really high in QPS. The company says they get about 600 QPS. These are database QPS, not even service QPS! Now no matter what kind of operations you're doing, correct query and index planning should serve you ok. Looking at the graph, there are a lot of updates going on, so I would say GridFS is out of the question.

MongoDB WT (and 3.2 especially) really moved the Mongo to the next level, and it's really weird to hear that it took so long to upgrade to WT. We moved a system to WT from MMAPv1 in the early 3.0 days (and to 3.2 later) and saw improvements in read/write 99.9th percentile latency, general ROI on instance utilization, QPS, and especially snappy compression bringing an X0 TB deployment to more reasonable scale as far as storage goes. This is not a crazy system, but peaks of 100k while jobs calculate and constant load of 50k QPS is very straightforward and WT responds beautifully to.

As mentioned before, this is a bug that got a number of fixes upstream (though 3.2.10 came out just only yesterday), but one of the only reasonable way to hit that load was to insert/update a lot of documents on a very slow underlying disk. Test your workloads before upgrading -- but there is something severely wrong going on with your deployment/query planning if 600 QPS per server is bringing cache issues, especially given r3.4xlarge underlying hardware.

Right. My wife sometimes has auditory and occasionally the sorts of visual hallucinations you mention. I suspected it for some years but never asked her. She finally told me about it a few years ago. I've known her since the '70s.

It's not an easy thing to discuss with people. There has to be a lot of trust that, even if this person I tell thinks I'm crazy, they won't ditch me because of it.

Can someone explain why notifying the device of exercise and eating is necessary? Is it because 5 minutes is too low of an interval, or because the glucose sensor is slow, or because the body relies on other eating and exercise cues to regulate insulin.

You have rights and easy access to your data - always have.

And who would enforce such a right if we have no governmental oversight?

If they did, they'd be breaking their own value prop of a place to share things, which by definition means people need to be able to get at it easily.

Facebook's value proposition is people sharing things within the platform. You can perfectly well provide that service and at the same time make it hard for users to migrate their data to a different platform. They already did it in the past. [1]

Again, this stinks of non-customers trying to interfere with Facebook customers for dubious reasons out of fear.

Indeed. In this case, the non-customers are Facebook's users and I believe the fear of entirely justified.

I'm not sure where that number comes from. Every year around a hundred thousand of such letters get sent (with a downward trend and half of that from a single law firm). But I'd say the vast majority of internet users in Germany is aware of their existence.

Edit: After looking up some more data, at the peak in 2010 there were estimated around 500k of those letters and the million bar was likely crossed.

Dang, I've always been a fan of Dropbox, but after upgrading from El Capitan to Sierra I opted to completely cut Dropbox out of my tools used, as I only ever used it hold an archive of documents I wanted to keep but don't interact with often (Such as license files for software and online receipts for things like tickets bought and stuff) and opted for using iCloud Desktop & Documents.
Just to give a little more context. This is a start but it's by no means the finish line. Additionally, this is just one company's closed source system that is kind of the "Tesla AutoPilot" for diabetes. It will TRY to keep you in the lines but if there is a real turn or a stop light, you absolutely need to take control.

Go google for "OpenAPS" and "WeAreNotWaiting" for existing open source systems that do more than this Medtronic system does...they are available now and there are over 100 people using them 24/7.

My experience is that file sync is all about edge cases, and there are so, so many. I believe Dropbox is the only one that has solved most of them (a function of time, energy, and large user base).

A colleague just had google drive not properly syncing for 2 weeks, and all of the sudden it started working except it overwrote a very active Sketch file with the two week old copy (and no duplicate "conflict" copy made as Dropbox does). Google around and you'll find many such stories across all services.
The sensors aren't perfectly accurate; I don't know about the newer sensors which this closed-loop system uses, but the current generation only fulfills the accuracy requirements by reporting the median of 7 consecutive every-5-minutes measurements and carrying a warning of "don't trust these values if you have reason to think that your blood glucose might be changing rapidly".

My guess is that providing notifications of exercise and food (aka. "I expect my blood glucose to go (down|up) right now") allows the model to be tuned to respond more aggressively to new data at some times and less aggressively at others.

(The "less aggressively" side is probably most important: If the sensor suddenly reports a dramatic change in blood glucose in the middle of the night, the system should probably respond with "HEY WAKE UP THE SENSOR IS BROKEN" rather than "let's kill the patient".)
Because if you start exercising or eating NOW the insulin administered won't start working for 30 min and won't peak for 90-120 minutes. Because food hits you fast and by the time the system notices you'll have already drifted "out of the lanes."

Diabetes Closed Loops are the same problem as controlling the Mars Rover. You move the joystick and nothing happens for x minutes. Then you wait another x minutes to observe the results.
I like to keep that in mind when I consider what kind of solutions machine-learning will bring us, what kinda processes will be going on under the hood.
In theory the artists make some money on the streaming (youtube or streaming service of your choice) because its counted.

Not parent, but Google Drive has always been great for me. It has much improved from the clunky offering that was the release version. the only trouble I've had was corporate proxies, but God knows what hackery makes Dropbox work in this case.

Now you have the ability to selected nested folders to sync, it does everything I need, and the storage is shared with Gmail, Photos, etc.
My company pays for both and I had the same thought recently, but the consensus from the web seems to be that the Mac OneDrive client doesn't work very well.
