Is Wikidata only for notable data or any data? If only notable data is allowed, then how is that enforced? Who decides if some piece of data is notable?

Can data be permanently, unrecoverably deleted, or is it more like Wikipedia where you can usually go back to see text that was deleted (in older versions of an article)?

The way that units are being handled is troubling. Is the plan to assign a unique integer to every unit that's ever been used? That's a long list of integers.

Who are "we" in this context? I don't really think anyone in the western world seriously believes there is anything benevolent about China, full stop. What's happening here, and what IBM's statements clearly indicate, is that western CEOs think they might be able to goose their quarterly earnings for a year or two by kowtowing to whatever China demands. That means bigger bonuses and maybe more valuable stock for the CEOs, possibly (who are we kidding, certainly) lower profits in the long run as everyone knows China steals everything not bolted down and much of what is. But the CEO has no incentive to care about that.

There's also orgtbl-ascii-plot[0], there was a mode for writing out flow diagrams in Emacs that used a web backend to render them (I don't remember the name), and I'm pretty sure you could abuse some graphics-to-ascii or DOT file command line tools to get the required result in Emacs buffer - particularly via org-babel, which lets you invoke external programs to "evaluate" code blocks. I remember using some Java-based local tool to render graphs through org-babel, but again I don't recall the name or URL.

I guess what I meant was that you are emphasizing that the old-style format is what is the problem here, and that it hasn't been the default for three years now, but the headline makes the scope sound much worse. So saying 1Password as a whole suffers from this flaw is pretty misleading. I agree it's an issue that you weren't warned about the need to migrate to the new format.

The Salesforce plugin ecosystem (via AppExhange) is fragmented. Each app developer brings their own set of UI frameworks, resulting in a kludgy mess.

SLDS is a much anticipated and applauded UI standard.
Interesting. I'm re-building the core engine powering this using (basically all Javascript right now on Backbone) in Ruby + Javascript with an actual postgresql database behind it. Right now it's using an in memory store for things like your autosave drafts etc.

Do you think I should open source the project? Right now the Android app and the web-app (mentioned above) are closed source, but the philosophy of this platform is about open source writing - and to not have an open source application powering that seems antithetical. What do you think?

That is incorrect. Even if you don't republish the data, the scraping alone can be a violation of the site's Terms of Service, and you can be sued (and lose). See the Wikipedia article I linked above.

Think about it from the point of view of the site being scraped. Suddenly your webserver is being slammed with traffic that's way beyond what any human would cause. It's costing you bandwidth and compute resources. You have every right to say no, scraping is not allowed (in your Terms of Service). It's then up to a court to decide if those Terms of Service are legally binding. Some courts have decided that yes, they are.

> A minimal, service oriented, includeable library operating system for cloud services

I think the operating system for cloud services is need to be able to run heterogeneous system. Which Mesos & CoreOS are headed towards this idea via containerization.

Why build an OS that only run a C++ for cloud services? Is there any use case/problems that the author trying to solve?
True. You have to learn to treat programs written in dynamic languages as living, mutable, interactive things instead of designs set in stone. However, when a simple syntax derails your reading, it is a thing of concern.

Then again, you could make similar shenanigans in Common Lisp with `symbol-macrolet', but it's obscure feature that pretty much by definition will be used only by people who know when to use it :).
After a quick review of the KeePassX website:

* The screenshots are from 2003 era software (XP & Mac OS X 10.3)

* The requirements page says "Qt Library >= 4.3". Does that come with Windows?

* The downloads page doesn't specify if it work on Windows 8 or newer, or Yosemite / El Capitan for Mac.

* The website appears to be running an outdated and exploitable version of Wordpress, and is broadcasting its version number in the site source code.

And an actual quote from their support forums:

"I've got to say this is the deadest forum I have ever joined. There's so little help here that I'll advise anyone who can't figure things out for themselves to pay-to-play one of the bigger, commercial password managers. I'm done here - I don't see any reason to return."

This is common to a lot of open source projects. A product is not just the code, it's about usability, building trust, educating users, explaining things in a way they understand, and providing timely & friendly & helpful customer support. Code is barely 10% of a product. People pay for software because they want a job done well, and they don't want to spend more time than necessary on it.

Answer to "How": (Copied from another comment of mine)
a) The smaller company would have lower margins because they invest much more in superior materials, QA, R&D, etc. Where the larger company has an advantage because they invest more of their margin on ads

Regarding Adblock:
b) I posted another comment elsewhere about how choosing which ads are "acceptable" or not presents challenges. There is a lack of objectivity. It should be a choice between ads or no ads.
Mini rant ahead... I'm in Tempe (near Phoeinix). It is very frustrating that I live in a pretty large area in terms of technology and population. Yet, this seems to be one of the last cities to see services like this (instacart, AmazonFresh, etc). Phoenix is the fifth largest city in the country, and including the suburbs is #4 iirc. I realize we're geographically spread out, but so is the L.A. area.

All of that said, it's a lot easier to plan for per-delivery fees over an annual fee much more than $100, which you already pay for prime... I think they should just let straight prime members order with at $10-20 per delivery fee... that would be a lot easier to swallow.

Fair enough, but the entire web doesn't, which makes jsprogrammer's imperative practically impossible if taken at face value, unless one wants to avoid most of modern technological society altogether.
For those using 1Password, this isn't as bad as the headline implies.

1. This doesn't apply to local data

2. This applies to metadata, rather than passwords

3. This only applies to an old vault format changed in 2012 used for syncing via external servers [edit, specifically dropbox or folder sync, still in use for that it seems]

So 1Password leaks your metadata if you use the old vault format from 2012 and upload your passwords to a public service (or share them some other way), but that's perhaps not such an upworthy headline.

Personally I would use local wifi sync and keep your data local, whatever password manager you're using.
Insider trading would be even more useful (assuming that the trades are all visible). Once you see the insiders selling up ...
I'll start by saying I agree 100% with everything you said, and it makes me as angry as it makes you. You are dead right in all respects.

However... there is another subtle argument to be made here. The Han culture has no concept of integrity as we know it in the west. If it's easier or cheaper to steal something than to make it or earn it, they will, and there's no stigma for it. It's not surprising, then, that China steals from western corporations at every possible opportunity, and demands access to western inventions as a condition of market access. But suppose that instead we told them to go fuck themselves, accepted not having access to their "market" (such as it is), and let them invent the stuff themselves if they want it that badly. What then? There are only two possibilities: they go skill up and compete, or they go to war. They can't win a war with the US yet, but it's hard to imagine that such a war would be beneficial. And if they skill up and compete, they become much, much stronger. By giving away most of the store, China is kept fat, lazy, and stupid. They can copy, but they still can't actually do anything for themselves. Maybe, just maybe, that's better than either of the alternatives.

I don't really believe this myself, but I've often contemplated it when this kind of stuff comes up. Is anyone in the US (or EU) government thinking this way? Do NATO military leaders think this way? My guess is no, but it's hard to come up with any other rationale for western behavior here. Personal gain notwithstanding, if you don't believe this at least a little, you'd have to argue for simply putting China on the sanctioned countries list and being done with it, right?
I am happy too. Anything taking views from this hate and lie spreading paper is good. Ad block should not even try to circumvent this.
No, the problem is that they have a new format but the OLD one is the default. It's incredibly difficult to use OPVault as your keychain format if you aren't on Windows. Even if you are on Windows, you still need to change it every time.

I have 3 Rokinon/Samyang lenses and 2 Venus/Laowa lenses in FE mount.

Also the Sony 35/2, 55, 70-200, 28-70mm, 16-35mm and the 28.

When I do the specific count, "about a dozen" comes to 11.

I still have and use a fair number of Canon lenses with my Sony gear (using a cheap but effective Commlite EOS->FE adapter), but haven't bought any new Canon lenses since the switch. Obviously I don't count these lenses in my "about a dozen" as they aren't native FE.

I also use a bunch of 80s era Olympus Zuiko lenses with my Sony gear, some Nikon glass and a bunch of oddball Russian lenses.

While the complaint that the FE system is lacking lenses is true in a sense, the short flange distance between the mount and the sensor on the Sony mirrorless cameras means that if you're willing to deal with manual focus (which is pretty damn easy to deal with given the focus peaking abilities of these cameras) you have a whole universe of lens options since you can adapt virtually any lens to these cameras.

If you really need autofocus, you can still adapt a lot of Sony Alpha lenses with pretty decent AF performance via the LAEA4 adapter, and the A7R-II apparently allows for very quick AF with EOS lenses (my Commlite adapter for the A7/A7ii allows autofocus, but it is so slow that manual focus works better most of the time).
A queue is the correct pattern for a queue. A tree, of any form, offers no advantage.

The InfluxDB experience is definitely illuminating. Their problems with LMDB were mainly due to misuse of the API. https://disqus.com/home/discussion/influxdb/benchmarking_lev...

For batched sequential writes, there is no other DB anywhere near as fast as LMDB
http://symas.com/mdb/microbench/
(Section E, Batched Writes)

But even so - the reason LMDB can do this so quickly is because for batched sequential writes it cheats - it's just performing Appends, there's no complicated tree construction/balancing/splitting of any kind going on.

If you know that your workload will only be producer/consumer, with sequentially generated data that is sequentially consumed, it's a stupid waste of time to mess with any other structure than a pure linear queue. (Or a circular queue, when you know the upper bounds of how much data is outstanding.)

As for your initial statement - no, an LSM tree is not a correct pattern here. If your consumers are actually running as fast (or faster) than your producer then it should never flush from Level0/memory to Level1/disk. In that case all you've got is an in-memory queue that evaporates on a system crash.

If your consumers are running slower, that means data is accumulating in the DB, which means you will have compaction delays. And the compaction delays will only get slower over time, as more and more levels need to be merged. (Remember that merge operations are O(N). Then remember that there are N of them to do. O(N^2) is a horrible algorithmic complexity.) LSM is never a correct pattern.
