TerarkDB is a RocksDB replacement at ByteDance, optimized for tail latency, throughput and compression.

RocksDB is a fork of Google's LevelDB [1] at Facebook. Optimized to exploit many CPU cores, and make efficient use of fast storage, such as solid-state drives (SSD), for input/output (I/O) bound workloads.

LevelDB [2] is an open-source on-disk key-value store written by Google fellows Jeffrey Dean and Sanjay Ghemawat. Inspired by Bigtable.

Bigtable [3] is a compressed, high performance, proprietary data storage system built on Google File System, Chubby Lock Service, SSTable (log-structured storage like LevelDB) and a few other Google technologies.

I hope the info above is useful for others as I dont have the slightest idea what RockDB is, but I do know LevelDB.

Differences between AC and DC power distribution and why you might chose one over the other. TLDR, AC is the most common choice for good reason, but there are also conditions where DC would be the better choice:

You may have heard something like "AC is better for power distribution than DC." I would not go so far as to call this a lie, AC is in fact "better" than DC in lots of common cases, probably the big two being that at some (but not all) voltages, AC transmission is more efficient than DC and the second being that AC can be stepped up and down in voltage very efficiently without electronics or anything else more complicated than several loops of varnished copper wire.

Of course this is not true in 100% of cases. For example, at very high voltages (think 100s of thousands of volts) something called the skin effect can become so pronounced that DC becomes more efficient than AC. There's a high voltage DC power transfer backbone in Europe for this very reason. When you're dealing with multiple countries and potentially different standards for AC power distribution, this has the nice side effect of eliminating the need convert between frequencies and phases of AC.

The other, and probably the biggest reason you would choose a DC power distribution system is because your power source is DC. Pretty much all power is generated the same way, from fossil fuels to hydroelectric and even nuclear power - you use energy to spin a turbine, and that circular motion is used to induce an alternating current. There's really only one way to get efficient DC power and that's solar panels. Depending on the use case, the losses of converting DC to AC (and often, rectified back to DC again for the end-use application) may not be worth it.

Again, why are you championing the writer of a flagged comment? Like I said, I didn’t flag the comment. So clearly other people agree with me and saw what I saw. Sorry if that’s hard for you to swallow.
One more point I observed while UI performance debugging earlier: Even though JS are cached by browsers, still loading them from disk (cache) to memory during page load is actually slow. Of course it also depends on machine capacities.

> Our history with Native Americans is not a morally uplifting one. It is also not a genocide.

What a weird thing to say. Of course it was a genocide, that some tribes may have been slavers or that a meager remainder of their people and culture somehow survives in reservations doesn't make what Europeans and the early US did to their people and culture any less terrible, or not a genocide.
The average consumer is still a whole newscycle behind on that, but I think it's a stretch to say research in itself is advertisement. Headlines (which often do not even reflect the actual research content) might be advertisements.

In Xubuntu the login manager lets you switch between whatever DE you like. I think the Xubuntu login manager is lightdm so if you set that up properly you should be able to have both XFCE and Gnome easily. There were some ways Lightdm and XFCE didn't play very nicely together, especially around screen locking, but it's possible they've been fixed.
Author here. Thanks! I added a couple of these.
If you are genuinely worried that rebasing a feature branch into master will somehow corrupt the precious bodily fluids of your commits, reading a book on git will probably be the most immediately effective means to avoid littering everything with strange, possibly broken commits.

We all want to actually keep history, but unless you have set your IDE up to do a commit on every keypress there probably is also some subset of history you do not in fact wish to keep. So the question becomes what history should one preserve, and here opinions can legitimately differ. What I would suggest, at minimum, is not allowing force pushes to master or any other branches that you consider as "published" (internally or externally) -- easy to enforce on basically any git hosting solution or via a server hook. However this is a completely orthogonal question to choosing a rebase or merge based workflow. If master moved from my local branch, and I do a merge of a feature branch and force push, upstream history will get lost (baring a copy in the reflog or elsewhere).

By looking at the user's guide, it seem that Stan has also other use cases than Bayesian inference. Examples are linear regression, mixture models and even ODEs. Does anybody here have experience with Stan and R and could comment on the strengths of Stan in non-Bayesian contexts?
I'd say it's a hobby. Bullets are expensive in quantity. A full automatic can chew through $100 worth in just a minute. There are a few gun ranges near me that keep them available to rent. You can relive your A-Team / CoD dreams for a few hundred dollars.

Outside of the military they have no utility whatsoever.

That is cool. As an interesting coincidence, I also participated in the Netflix Prize contest, though I was never a contender. I did learn a lot about efficiently processing large datasets though. Good times.

This is such a tired argument.

Sure, politics is in everything down to the design of the armchair you are arguing from. That however doesn't fucking mean that all papers shall be considered equal?

Do you think you would be able to differentiate the value of a census statistics from a 2015 paper written by the state of Nevada from a 1930 census statistic paper from Nazi Germany? Excellent!

Because very obviously there is a line where science crosses into bullshit. Sure, the line is multidimensional, ever changing and very blurry. As you say, from finance to family everything factors in and there is no true objective way of doing science. That does not however mean we as humanity can get away with defeationist pseudo-enlightenment by just giving up every analysis of nuance or motive.

What Google is doing here is not in the territory of science anymore - you can and should argue that - and should be treated as such. The price of freedom is eternal vigilance, whataboutism won't cut it.

Edit: grammar
I guess its ok for non-business purposes, e.g. catching up with friends. It was a bummer having to bounce off to Messenger for that, especially when tg's user interface is smoother.
“Tail call” has a specific meaning in computer science, and it is possible to execute such a call without adding to the stack. Tail calls may not be directly recursive, they may be mutually recursive, or not even recursive at all.

Oh, interesting. Which country? I'll have to keep that in mind. In the <$local> highway code that I had to memorize , it's actually legal to use an unoccupied disabled parking space as a loading/unloading stop (for 10 minutes, say). You're just not allowed to leave your vehicle there -unoccupied- for an extended period of time.
>"The FoxDec (for Formal x86-64 Decompilation) project is investigating decompilation of x86-64 binaries into C code that is sound as well as fully recompilable. Soundness ensures that the decompiled C code is functionally equivalent to the input binary. Recompilability ensures that the decompiled C code can be successfully compiled to generate an executable binary for x86-64 architectures.

Formally verified decompilation

Decompilation to a high-level language involves multiple phases. At a high-level, the phases usually include disassembly that lifts assembly code from binary, control flow graph (CFG) recovery that extracts program CFG from assembly, extraction of high-level program constructs (e.g., statements, variables, references) from assembly, and type assignment. FoxDec is investigating techniques for the decompilation phases that are formally verified.

FoxDec’s decompilation phases include disassembly; CFG recovery; extraction of an abstract code that models a program as a CFG of basic blocks; converting basic blocks into sequential code that models the program’s corresponding state changes over memory, registers, and flags; variable analysis that maps memory regions to variables and references; and type analysis that assigns types. Converting basic blocks into sequential code that captures program state changes requires a formal model of the underlying machine (i.e., formal semantics of x86-64 instructions). The project leverages the Chum project’s formal x86-64 machine model for this purpose.

Central to formally verified decompilation is the notion of sound decompilation. FoxDec defines soundness for each of these decompilation phases (sound disassembly is explored in a different project) and formally verifies them: algorithms for each phase are formalized in the Isabelle/HOL theorem prover and proven correct."

“IANAL” and all,
My take is that legal work is, and has been, a high status domain of knowledge work requiring skill, effort and hard work to aquire. What cannot be solved with Excel&friends, may not be suited for such tools (or so they argue, to safeguard their knowledge).

A highly competitive market keep firms from collaborating on common [open source] goals and processes. Firms may have value systems far apart in their mission guiding their own work wich creates a social obstacle. A highly competitive (read: expensive) domain as it can be - professional signaling towards clients and competitor includes status and quality services; in which open source may be irrelevant at best, and dedicated person-to-person conduct of business is one of the best ways to deliver trust and quality. Maybe as a lawyer, you are better off using such de-facto standards as Clio.

I believe our most recent ML & AI have managed to breath some air into the historically tricky task of computationally work legalese in a practic way. A firm would probably keep a successful solution to themselves.

5G works on a variety of frequencies. The limits quoted are mmWave frequencies, which are very high 25 - 52GHz, and meant for short-range density.

The frequencies in this article are in the 3GHz range.
The issue is that jackasses don't document their finds. Context in which you found something is as important, if not more, than the item. Not to mention idiots destroy archeo sites because they are interested in trinkets they can sell rather than history itself. There is a reason why you don't dig up the entire site but rather put in a few trenches after noninvasive research.

Furthermore, a non-trivial number of people are just looking for reasons to move out of cities right now. Consider that many cities that we consider "elite" were losing population well into the 1990s. There's nothing written in stone about college-educated young people continuing to migrate to cities (which is pretty much the demographic that has moved the numbers) as they have over the past 20 years or so.
The parent's point was that if the user data (not the tree metadata) was corrupted in-memory before writing to disk, no amount of checksumming will save you because the checksum was calculated over corrupted data.

I’m curious about the HTTP/0.9 stuff. Last time I checked (four or five years ago, by making a trivial HTTP/0.9 server, as the first step of a “writing HTTP servers” tutorial series that never materialised), Firefox either wouldn’t render the output at all, or would render it as though it had been a text/plain response (can’t remember which it was). In other words, it’s not a real web page. I would expect precisely zero occurrences among the top million pages, not the thirty that 0.003% indicates. I think it’s far more likely (p≅0.9999) that these indicate some sort of error.

(For those unfamiliar with it, HTTP/0.9 is the label for a protocol where the client opens a TCP connection to the server and sends “GET /”, and the server responds with the body, verbatim, and closes the connection. No status codes, no headers, nothing.)

> Always was told that you can't beat hardware RAID

Recently with super powerful multi-core CPUs being the norm especially in places where RAID is a consideration, hardware RAID makes less and less sense. You just create additional complications like when moving your RAID array between 2 otherwise identical cards but with different firmwares fails. So you end up always buying spares and testing the migration before putting any data, then you freeze the config in place. On the other side you may be stuck forever with a buggy firmware.
He was home alone.
The fonts on this page changed at least three times while I was reading it. Never seen that before. Points for effort!
Where as I was always told to avoid hardware raid if possible, and that's been a mantra for 15+ years.

The reason I was given is twofold. 1) If your RAID card dies it's nice to be able to plug drives into any controller and be able to access the data. 2) "look at how often MDADM fix bugs. Now look at how often your RAID card firmware gets fixed... use MDADM".

Modern filesystems like btrfs & zfs both prefer to deal with the RAID aspects themselves as it gives them far more control. Even if you're a hardware raid afficianado, I wouldn't recommend formatting (eg) ZFS on top of a hardware raid pool.
I guess it's a combination, the lack of marketing for sure. Perhaps it's also the algorithms fault, if only a few people (considered from a worldwide view) download it, it's not shown to others looking for map apps (it's a very crowded space app wise).
Czechs are very outdoorsy people, they recommend this app to each other and so it's very popular there, but unfortunately the language barrier makes it harder spreading over borders. But these are all just wild guesses, who knows? Most people here in Germany use Komoot which gives away their maps for free on a regular basis, perhaps that's better marketing than "everything is free already"... :)
I was hoping it was a questionnaire about how bad Spotify recommendations are. I have no idea why Spotify feels the need to clutter my recommendations with radio stations like "Rap Caviar" and "Music for when you know you're the bad bitch", meanwhile it doesn't show me new releases for music I actually listen to because of all the irrelevant suggestions taking up space. I ended up creating a new account because apparently listening to a couple of podcast episodes means you want half your page filled with recommendations for shows on the same topic.
Where geographically are you basing that on? In another reply 6nf mentions Osko etc. on the New Payments Platform in Australia, which is fully settled in real-time, 24/7, but even before we had that our Bulk Electronic Clearing System (BECS) cleared and settled everything twice daily on business days and Real-Time Gross Settlement (RTGS) has existed for years for high-value domestic payments.

Cross-border payments have usually taken longer, but the point of my comment is that that is very quickly changing (and already has come a long way in just the last few years). So you may be thinking of older technology or places with less advanced banking systems than what a lot of countries have now?

I used to work at the Google San Francisco office, back when there was just one SFO office. IIRC the office was 5-7 floors with one “bathroom” per floor. I remember having walked up and down the entire building to search for a toilet, eventually giving up to go use the one at Starbucks.

Certainly not employee mistreatment all things relative. But it made me stop and think how much Google values engineer time, and how I feel in terms of productivity.
I have the same motherboard and the same enclosure. The enclosure is really great, well designed and easy to use. For the heatsink, I actually bent some of the pipes and used the lh6 kit to use two sides of the enclosure for heat dissipation instead of one side only.

The thunderbolt port on that mother board works great. I have an egpu that I'm sharing between my laptop and this computer and it works perfectly on windows. I haven't managed yet to configure VFIO so that it works well on a windows VM in linux though.

Unions are for more than just getting higher pay.

If Google (perish the thought) decided to pull some shady reviewing stunts and make your work life so intolerable that you felt your only option was to force the issue and threaten to resign - being part of a union could have helped with that.

HR is a bunch of people who represent the company's interests in negotiations and transactions. Unions are the same thing for employees.

We've been told, repeatedly, that unions are socialist organisations that want to destroy capitalisim and bankrupt employers. This isn't true.
I will get beat up for speaking up on this topic, but you are right and its related to food based on my researching this topic in nih.gov. First world countries are experiencing the highest mortality rates because of eating garbage. Insulin resistance being at the root of most of your mentioned down-stream problems. There are also a lot more chemicals in foods now. Pesticides, fungicides, etc. leading to auto-immune problems, allergies, chronic low-grade inflammation, higher triglycerides, higher small dense particles in the LDL cholesterol. To find some of the studies backing this, use google and put in queries like "site:nih.gov insulin resistance" and other similar terms. Some of the studies contain graphs by country. The most fascinating studies are the ones that include cultures that are still hunter-gatherers. Most of them have no traces of cardio vascular disease, mental illness, obesity and certainly no diabetes.
I listened to a number of audio books by the same author during a road trip last year, this tells me I listen to this author to an uncomfortable extent ;)
