Hi HN, we built MarketStore, now opensourced, to address scalability issues around handling large amounts of financial market data analyzing price history with data spanning many years, including tick-level for the all US equities or the exploding crypto currencies space. You can think of this as an extensible DataFrame service that is accessible from anywhere in your system, at higher scalability.

Looking around github, many timeseries databases were there but mainly for general-purpose timeseries data, targeting IoT sensor data or system monitoring metrics and designed for JSON. Financial timeseries data, in particular, has different requirements, in which the data is pretty dense, more structured, and long history is demanded. We couldn’t find the best solution for our financial markets use case. It was obvious that not just we but also anyone who works on this financial timeseries data would need this solution. In the coming age where more and more people write automated trading systems and try to analyze this kind of data, it is inevitable to handle it very efficiently.

We wrote about a specific use-case dealing with Bitcoin price data for crypto algorithmic trading.

And if you’re interested more in the development/internals of this project, we wrote a post when opensourced MarketStore. We love to hear your feedback!

It does not. You have to explore XPrivacy to know what fine grained looks like. I can not explain. Also Android does not show all the permissions that XPrivacy can.
Yes, but then there's studies showing spanking children makes them more aggressive. The physical abuse of children is by the physically abusive who were themselves physically abused.

It isnt merely accidental. Of course it isnt the explanation for WW2, or the 1970s murder rate. Neither is lead.

The question at hand is not whether you would support Franco, because pretty much nobody is going to own up to that; it's who you would support out of the insanely complicated web of alliances that made up the Republic.

The Russians managed to acquire millions of dollars of gold reserves from the Republic in exchange for a disappointing array of weaponry, distributed only to their cronies, and accompanied by incompetent military advisors who were more interested in looking good back home than in winning the war. The anarchist unions seem to get more respect, but there's a strong argument that they were militarily ineffective, that their resistance to the Russia-aligned PSUC was destabilising at a critical period, and that the middle of a war against ascendant fascism was not the greatest time in the world to start redistributing land and making enormous social reforms. That's not even getting into Catalan/Basque independence, all the little minor parties, the different police factions, the wave of assassinations that led up the war (though fewer in number and in response to similar assassinations), the immense difficulty of forming a stable government, etc.

Reading into the war gave me a greater awareness of exactly how badly the "good guys" can behave, while in no way mitigating the horrors the Nationalist faction committed.

There is not fine grained permissions. There is something that is better than it used to be, but fine grained is not what I'd call it. For instance, I believe the following should be possible for photos alone.

* Give an app access to only save, not read my photos
* Give an app ability to read one specific photo (think upload a photo to facebook)
* Take pictures without always having access to the camera.

That is fine grained.

> Isn't it kind-of breaking embargoes if a binary security update goes out weeks before the vulnerability is documented in public?

Sort of. But it's a balancing act -- if you delay the release of a fix until the day of disclosure, users are all vulnerable to a known exploit until they patch. If you release a patch before public disclosure, chances are much better that users will update before the vulnerability is disclosed, either officially or through reverse-engineering of the patch.

3 Key Traits of Mobile CRM Solutions That Can Drive Business Growth
In the Colorado laws, "creed" refers primarily to religion and distinguishes between what you're referring to here with a religion at large, and a person's belief system under that religion, which is their creed. In either case, religion itself is also a protected class under federal law. Though this may be tangential. The main defense in this case is one of freedom of speech.

If you're interested in this there an immense number of really interesting filings, particularly 'friend of the court' filings on this case. You can read them all here: http://www.scotusblog.com/case-files/cases/masterpiece-cakes... They are loaded with interesting anecdotes of the implications of a ruling either way, along with precedent. For instance in one famous case an individual in New Hampshire did not want the state motto, live free or die, on their license plate which was a part of the state standardized and controlled design. The courts ruled that free speech protects the freedom to say things as much as the right to not be compelled to say things. The reason that's relevant is that no reasonable person could think that it was the individual themselves saying "live free or die" but nonetheless it was still seen as compelled speech as the individual was being forced by the state to promote a message they disagreed with.

So then the natural issue there is that the cake itself is not directly stating anything, again like your rationale on the bible cake verses. But there is court precedent declaring everything from photographs to engravings to stained glass windows to... topless dancing as protected speech under the first amendment. It seems likely that wedding cakes would follow in the same vein. When people spend hundreds of dollars on these cakes, they're implicitly spending most of their money not on the cake, but on the artistic expression of its creator.
Most modern gui toolkits bother me in ways that I can't adequately express. All the more so because most fallback to thinking CSS is the answer. Often completely ignoring what you can easily accomplish if you are willing to use absolute positioning, oddly enough!

Seriously, I don't think CSS is the worst answer. However, trying to get everything to work with some default flow behavior is borderline insanity. More, it is completely unnecessary. My favorite example lately has been http://taeric.github.io/cube-permutations-1.html for how you can layout using absolute positioning perfectly fine. (I similarly did sudoku with minimal effort using similar markup.)

But the worst sin is the sheer instability of what we are building as our foundation. The box and glue methods of TeX might not be the most intuitive method, nor the most powerful. However, it is nice that they have been stable. And not just in the "doesn't crash" sense of the word. In the, "I would feel comfortable building on top of it" sense.

So, let me be clear that I'm skeptical, but I would be delighted to be proved wrong.
It is not purely functional. The main difference from r7rs scheme is that lists are immutable, but that has been the idiomatic way in scheme anyway.

It even supports generalised set!.

I don't think so. 48% of people have access to the internet, 41% in developing countries. All these people won't be able to benefit from this at all. That doesn't even count the ones that have dialup or comparable speeds (like on Cuba) where transferring anything beyond a couple hundred kilobyte is unbearable.

The wealthy will employ AI the moment it can do the same tasks as a human, unlike humans the AI is cheap, doesn't take time of work, always available, never tired or grumpy, etc. The maintenance work of having an AI worker vs a human worker is just way lower.

The moment a corporation like McDonalds can replace the entire staff with robots without having a dip in efficiency they will do that. 24/7 operation would be linearly more costly to 9-5 weekday operation.

Firstly, getting a PhD is hard work, even when you think you've taken in account everyone telling you it's hard work, it's still harder than you think.

Secondly, it's extremely unlikely that research in academia aimed at getting a PhD will be suited to being turned into a business. The purposes of "research for degree" and "research for product" are totally different. If you try to achieve one by doing the other you'll likely succeed at neither.

To answer the question you started with, the problems you work on in getting a degree are ones agreed between you and your supervisor during your preliminary work. For a PhD you need something sufficiently mainstream as not to be dismissed as a toy problem, obscure enough that no one else is likely to be working on it, hard enough that results are worth the degree, and easy enough that you can make progress in a severely limited time. As I say, finding a problem that suits those criteria and then also asking that it's research that can be turned into a product is all a bit much.

There are avenues to explore other than taking a PhD. Spare time projects, contributing to Open Source, reduce your hours at BigCo and start a consultancy on the side, go freelance.

A PhD is probably not the best option, but in the end all I can do is provide an opinion for you to take as grist to the mill.
Actually that's questionable.

Your connections and social media activities carrying lots of value and allow FB to serve better ads to connections.

Paying for no ads does not eliminate that important element.

Certainly - tricking someone to click on ad and charging advertiser for worthless click is a source of revenue - but it doesn't bring $500/mo or something.

"Rendering via DOM" enables rich text via HTML which is much more (and nicer) than "bold and italic fonts" and "images". For example look at the 'domterm help' output in the right upper pane in http://domterm.org/images/domterm-panes-1.png - it is not true than many terminals can display this. (Except of course in the trivial sense of using a library to render to an image and then displaying the image.)

It is also worth pointing out that most of the features you mention (except 1 and maybe 3) use protocols that are not widely supported. DomTerm uses familiar HTML wrapped in a trivial escape sequence. A related benefit is that reflow on window resize works - and you can copy/paste or save as HTML.

"Awful slow" is relative. DomTerm does take some extra seconds if you 'cat' a large file - but if that is your primary measure of a terminal emulator then our needs are very different.
If you read the article they are changing it back to Red Hat CoreOS.
I believe the API for that actually exists, it's just that no app uses it because the UI/UX for that is messy. It's much easier to just requests access to all files.
All of those options exists and are implemented - apps can invoke OS photo picker which exposes a single photo. Apps can store photos to storage without requesting read access to other directories. Apps can request a photo intent which opens camera without exposing anything to them.

You just choose to use apps which instead request you give them permissions to whole photo storage.

Prime series are palindromic. Given the set of primes (2, 3, 5, ..., p[m]), there is a repeating pattern of length r = 2 * 3 * ... * p[m], where nr +/- [ p[m+1], p[m+2], ... p[m+q] ] (p[m+q] < r/2) are relatively prime to the given set. When n = 1, the only relatively prime integers which aren't truly prime are those which are some combination of two or more p[m+1] ... p[m+q]; the smallest is of course p[m+1] ^ 2.
Oh, you mean like the "too-dark-to-see" scapegoat camera in that very case the article is about? Riiiiight.

This is great and all, but I just wish they'd fix it so that bluetooth connections don't crash the UI on my phone.
This bit is so ironic to the point that I feel they must be trying to convey a message that is not directly stated. 17th century colonial Massachusetts. Doesn't that ring a bell for anybody else? Salem Witch Trials.

In 17th century Massachusetts the just arbiters of truth, naturally being the Massachusetts Government, would soon fall to frenzied lust in pursuit and prosecution of 'witches' for which they tried, convicted, and executed numerous individuals. The same body behind this is the one that was also responsible for judging what was true and what was false and doling out punishment accordingly...
"Defect" always seems like a johnny-come-lately polishing of the word "bug", rather than vice versa. I would be surprised if "defect" is truly the original term for a software bug, and "bug" was chosen as shorthand.

In any case, bugs need not be only in software. As as earlier comment says, bugs can be in specs, too. Here, the spec was buggy and that has been resolved.

Or to put it another way, the defect was in the spec, and that has been resolved.

(Note that many specs are implicit and best derived from the software in question. If that is the case for Notepad, then fixing the bug in the spec requires one to fix the code. I somewhat doubt Microsoft follows that practice, but it's certainly not beyond the realm of the possible.)
Just turn it off. There's a literal setting for that and it directly asks you to enable it when you set up your phone for the first time.

I use a Thinkpad with Linux for work and I agree that the keyboard is better than a MBP's.

However, even though I use the keyboard more than the trackpad, I find that I still rather use a MBP because the difference between the trackpads is greater than the difference between the keyboards. Also I like the screen on the MBP better.
No it's not and the default configuration doesn't do that at all.
I think this is true, but it’s also a bit frustrating in that it’s not at all obvious that programmers are building more or better stuff as a result of the “bad working environment” side of things. So can’t we just lose that?

(It probably doesn’t help that preferences are quite variable. I’m generally pretty comfortable doing tight-deadline stuff at least some of the time, especially if it’s clear why someone needs the thing fast. On the other hand, I’m not a big fan of some of the current process/“practices” stuff, and can see that people who enjoy a fair amount of structure could dislike an environment I found near-ideal)

You're right, and I might have been a bit quick on the trigger. In this sort of case there needs to be something that highlights this particular submission as being different. Unfortunately the otherwise reasonable policy of always using the article's own headline fights against the idea of the submission title actually saying why this submission is important and/or different. What I do in (the rare) cases like this is immediately add a comment saying why this submission is not like all the others.

Sometimes it works.
This is simply not true. LocationManager API works well still.

Not all the same flaws; malware will have a much harder time recovering it. Also, you can use a regular password to "semi-authenticate" with the call center of the service and try to get them to disable the second factor, but this PIN is only useful with physical access to the device.
The twin studies suggest that you can "break" your kids (and damage their outcomes to some degree) if you go too far in most directions, but that as long as you don't do this and you stay fairly moderate, their outcomes depend far more on nature than nurture.

In the case of tiger moms, the confounding factor is that along with their overbearing parenting they probably passed along some highly effective genes, though the kids probably would have been just as effective (maybe even more-so) with a more relaxed upbringing.

SOA never required an ESB, this was simply vendors trying to shoehorn in a saleable unit of software - which they succeeded at better in the 90s. Likewise I've seen people implement microservices with an ESB in the middle.

Long an short of it is the ESB is an anti-pattern, always has been and SOA and microservices are the same thing.
fgrep is the way to go here. It uses a different algorithm that makes only one pass through the file while searching for all strings simultaneously. An extension of trie search.
This. I don't buy MacBook Pro because it has Aluminium body, but because of the quality of the components inside, and how they integrate well with the OS.

My dream computer would be

- ThinkPad like casing. Light weight, yet durable. Not some cheap flimsy plastics.

- XPS like thin bezel display, with Apple like screen with colour calibration. While at it, please give me a 16:10 or some other tall displays where I can have more vertical space. 16:9 is only good for media and it is a secondary use-case on my laptop.

- Components with wider/open source drivers like intel wireless card instead of the Broadcom stuff. Some bluetooth module that has proper working Linux drivers.

- Trackpad - Mac like smooth trackpad. It's been decades and nothing comes even close to what Apple could do.

- Decent 12 hour real world battery life. I don't care if it makes the laptop slightly thicker or heavier - it is worth it.

- Keyboard with a good bit of travel - Like a ThinkPad.

- No Dongle life. Want USB-A, USB-C, HDMI, MiniDP, Full size SD card slot.

So far, only MacBook pro (with VMs running Linux) comes closest with several compromises.
It looks like it's taking measurements from live process, so probably not arch=native. But most likely the runtime profile guided optimisation would do a similar job.

I don't see that as a flaw really. It's not different to having a password manager, with proper WebAuthn atleast.

What you do is you take this key that unlocks the kingdom.

And then you keep it safe.

Unlike before there isn't 20 keys that unlock parts of the kingdom that might lead to unlocking other kingdoms via roundabout ways. Your attention for security can be focused on a single key.

The average users will be much safer if we force them to only have to remember one single password that can be securely used for everything without the usual drawbacks (that's why security people recommend password managers)
