> That is a terrible attitude IMHO - why should they have to have to learn how to talk to developers? Your cynicism towards “typical users” probably harms you and your career.

I think I'm sensing a bit of anger in your tone, looking how you move the subject on my person.
Sorry if I offended you in any way, it was not my intention to offend anyone.
Me and my career are ok so far, if that's of some relief to you.

We are surely not working in the same area then.
Mine is as a vendor of enterprise stuff, for Big Corps.
In my place, not relying in users' proactive and qualitative feedback is a pretty decent attitude in my eyes, it tends to deploying more reliable software, thus to invoices actually collected, which finally leads to having an actual paycheck.
It's not clear to me how active Elon was with PayPal, I really think it was much more Peter Thiel that made it successful (although I am not claiming expertise). Elon founded x.com which merged with what become PayPal, but as PayPal started to become successful it was Peter Thiel at the helm. That doesn't mean Elon wasn't instrumental to its success, only that I cannot find much evidence that he was instrumental to its success.

https://en.wikipedia.org/wiki/PayPal#Early_history

> In October of that year, Musk made the decision that X.com would terminate its other Internet banking operations and focus on the PayPal money service.[25] In the same month, Elon Musk was replaced by Peter Thiel as CEO of X.com. The X.com company was then renamed PayPal in 2001,[26] and expanded rapidly throughout the year until company executives decided to take PayPal public in 2002.
It's not a dot, in a long exposure photograph, it's a line. You don't delete it spatially, you'll want to subtract off the extra photon counts along that line so you can retain whatever was in that part of the image. Now, I think that's possible - find lines one diffraction-spot wide, fit to its brightness and subtract it off. They should be damned near straight lines of constant brightness given how fast satellites move, and the transverse profile should be exactly given by your telescope's point-spread-function, so you should be able to locate them and model them for subtraction very well. I think it can be done.

Photon shot noise is sqrt(N) though, so even after the subtraction you're left with more noise along that line than elsewhere. So that's not ideal. But increased noise is less of a concern that "totally ruined data".

Another caveat is that the lines have to not be so bright as to saturate your CCD, otherwise you truly have lost data that subtraction won't help with.

Edit: it turns out astronomers take many shorter exposures [1] and simply reject the pixels that are too far away from the mean in any given exposure when combining them. This seems mostly better than what I was proposing, though it does mean increased readout noise since you read out multiple times and so for very sensitive measurements I would still expect astronomers might want to do true single long exposures.

Is there a way to do the reverse?

There's a quite "legendary" Game Boy Advance game out there (Klonoa - Densetsu no Star Medal) that never got a translation to English because it has some sort of in-house created compression by Namco applied to the game that was made so it could fit into a GBA cartridge. AFAIK no one was ever able to crack it open and release the code to de/compress it.

A while ago I had a "bounty" of USD100 for anyone that could do it (just the decompression and re-compression, not translation) but there aren't many people that want to fiddle with low-level GBA coding.
The article (apparently falsely) claims that default JVM GC does that:

"Short-running programs, like all programs, invoke the garbage collector at the end of their run."
nice project. the next step is to use ML to create better compression algorithms
This one is really cool! Never seen anything like this before.
Arguably the first Alphas could have had a C compiler with 64 bit bytes but that would have made porting hard. Even then they were forced to add byte operations pretty early on.
The Citroën Evasion had to be renamed Synergie for the UK market, because while in French évasion means "escapism", in English it brings connotations of tax evasion.

Citroën had this problem a lot with their vans: they also have a commercial van called the Jumpy, which obviously isn't something you want to say about any vehicle, so it was changed to Dispatch for the UK. And they have a larger van called the Jumper, which was changed to Boxer, probably because "Jumper" also carries criminal connotations in English (bail jumper, stile jumper, etc.).
Now that 2020 is around the corner, I'm wondering the latest technical development.
What I have observed over the years is that Musk routinely burrows into engineering considerations, for better or for worse, most especially at SpaceX but also with regards to manufacturing, specifically, at Tesla. He is an engineering enthusiast with a well documented skillset.

Regardless of how we characterize Musk, however, reducing the issue at hand to a pro/anti Musk ad hominem argument is a distraction and a waste of time. It is suddenly relatively cheap to put a huge number of small satellites in low earth orbit. This creates a conflict with astronomical interests. What remains is a policy debate worth having.

SpaceX's statement may be ignorant, erroneous, or even deceitful. I have no doubt that the astronomy community identified the problem immediately and has been trying to bring it to public attention. However, as with light pollution at both optical and radio frequencies, they are relatively powerless compared to the interests with which they are in conflict. If the FCC is the arbiter of how many satellites a company can launch into LEO, they have already lost. This was a regulatory and legislative battle that they needed to be fighting, and probably were fighting, and basically had very little chance of winning unless they were somehow able to mobilize public support for earth-based astronomy against the telecommunications industry.
Let's suppose there were 1000 rapes in NYC cabs in a year because NYPD doesn't keep good stats for various political, economic, social and tourism concerns. And ~2 billion rides/year.

Uber posted their stats: 3100 rapes/year. Let's call it 5500/year or 15/day.

NYC cabs: ~2,000,000 rides/rape

Uber: ~140,000 rides/rape

On the face of it, on average, NYC cabs seem over an order-of-magnitude safer than Uber.

All backtesting proves is that you have discovered a technique that worked in the past. Unless you have a time machine, that isn't very useful. The competitive advantage in quant and non-quant is identical, it is only the tools that are different.

It isn't hard. As I said, the first thing you have to understand is that 99% of managers cannot outperform and are not trying to.
As a Keybase user for a number of years I'm very happy with the platform. I'm probably part of the silent majority who use Keybase and have been genuinely happy with it and don't speak up when others have complaints. I use it for personal messaging and for my business and it has been great.

I think Keybase's position on this is on point. This is spam and needs to be dealt with as such. It's no more an issue than with email. Anyone can send you a virus or harassing message in your email, but where is the angry mob of people beating down the doors of every email provider?

There is certainly a problem that needs to be addressed, but lets not blow this up into something it is not. Keybase's spam controls will continue to mature as it grows.
You say that like it's a bad thing!

But the TeX math is interesting to discuss: it turns out that you can skip the usual multi-second download/parse/render/reflow workflow of MathJax JS libraries on a static website by preprocessing the final HTML pages using https://github.com/mathjax/MathJax-node . This gets you pretty much the best of all worlds: it renders instantly without JS, looks good, works cross-browser, and is dead-simple to set up as you just pipe into a tool. Definitely the best way I've found for static sites to render math.

The Delta Force series liked its realism.

In another genre, Bushido Blade & Bushido Blade 2 are semi-realistic (jump height's exaggerated, but otherwise pretty real-ish) weapon-based fighting games. I'd love more like them but haven't seen anything similar since (both are on the original Playstation). One-hit-kills are common, and you can cripple limbs—arms in the second, legs in the first—both are limited in the realization of their ambition by technology and, presumably, budget.
How about using MDMA for couples therapy ?
Application startup time usually is dominated by class loading, JITs and actual application initialization code. GC overhead should be fairly small unless the heap is badly sized.
You might be able to shave off a few milliseconds by tuning the GC, but the lion's share is somewhere else.

You could try OpenJ9 for CLI tools which claims to offer faster startup times out of the box compared to openjdk. Tweaking the JIT behavior (number of compiler threads, compilation thresholds for the tiers etc.) or using CDS can help too.
Not so much wrong, more out of date?
How about the enterprise version of windows. I feel like there are restrictions they would put on consumers, that they would not put on an enterprise. Even if it costs more, it might make you happier, if you get a better experience.
Peltier coolers won't do anything but draw power and create more heat you have to dissipate, they're not magic you have to remove the heat from the hot side too which means you need radiators for them too plus more than you'd need originally because peltier coolers are quite inefficient.

Same thing with the LED idea converting that heat into electricity requires some heat differential which requires... a radiator.
The Finnish skier Eero Mäntyranta probably owed much of his success to his polycythemia, significantly increasing the number of red blood cells and thus the oxygen-carrying capacity of his blood. Since red blood cells are produced in the bone marrow, a transplant could be used to deliberately induce polycythemia. However, a quick search for bone marrow transplants for polycythemia yielded only results about curing the disease with transplants.

Probably not a great idea, especially considering it would likely be considered a form of doping and get banned.
The irony is that modern society has made great strides to promote relationships between all combinations of genders of individuals... but any suggestion of non-monogamy is still struck down with shame or castigation almost reflexively, with little to no thought. It’s getting better though.

There would be several advantages to a suit over a robot over and above cost.

Ability to do an unlimited number a tasks without major retooling would be one.

Minimal maintenence and upkeep would be another.

Thinking abit more about it, there would be more uses other than just automating labour.

I could see a suit being very usefull in a training situation such as learning to dance using the suit then when muscle memory kicks in the suit can be taken off. (This is simmilar to the utube video link posted in the comments)

How about for snipers? With the suit on a sniper could hold steady on a target.

Then theres the whole tele-presence surgery idea.

IMHO the most important thing is it creates a symbiotic relationship with humans and automation rather than getting rid of the human.

All that said I kniw a suit is a pipe dream but maybe a long sleeve glove that allows you to pick up a pen and draw a computer generated picture might not be that far out.
I wonder, "just how significant"?

In this case, shower can be converted back to the bathtub, for not too much money/time.

Besides, once the house is sold, usually some interior changes are made by seller and/or buyer, e.g. new paint inside, new appliances, furniture etc, which all takes time and money and converting the shower would be just one more thing to do, and a relatively cheap one, too.

I use Windows 10 (home edition) at work and have no real problems. There is Win7-like panel, Explorer for files and the command prompt - what else do you need?

They have spoiled the configuration dialogs - finding where to tweak something would be hard if I couldn't just Google it, but you just configure it once and forget it.

Mysteriously it has also never shown any ads to me although I didn't do anything for this.

Windows 10 is not great but it's ok.

And I totally love the option to enable keyboard input autocomlpletion (if only I could also enable this on Linux and Mac) - that's amazing when you have to write in foreign languages.

It’s a custom log-based block device implemented on top of Colossus/D in the user-mode lib in the virtualizer (Vanadium). Guest OS communicates using NVMe or VirtIO, Vanadium intercepts, calls PD lib.

This design has only one hop to the storage node. Low-latency workloads benefit from this design, high-bandwidth workloads sometimes actually benefit from off-loading PD to another host. To do iSCSI with one hop, you need to implement iSCSI interceptor, and basically you would have same design with less flexibility for guest OSes.

The irony, of course, that all this is a lot of legacy technologies needlessly wasting computer power: guest file-system trying to communicate with 4K blocks with “block device”, which goes through multiple layers of queues, then is re-maps to another abstraction, which goes over network to multiple hosts, etc. Not a single cloud customer ever said “we are so excited to manage volume sizes and bandwidth quotas for PD”. Better design would be to implement true data center-level filesystem to better support container workloads and leave PD for legacy cases, but Google’s storage management is so detached from reality, that it’s impossible to do cross-organizational project like this.

But in that case you have to travel to a remote location (most likely using a car or plane ironically).

Hence, is it so far fetched that if you want to explore space in future you will do it from a different vantage point? Like via a satellite, or maybe in 50 years you go to a space station or the moon directly to do so.

Hard to identify delusions in worms. But the entropy / free energy models work for the best understood worm brain (C. Elegans).
This is a really great question. The fun thing about population genetics, (as opposed to the more experimental fields in biology) is that we can actually enumerate the forces (mutation, selection and random drift) that are acting on our subject of inquiry (an antibiotic resistance gene in a population of bacteria). The phrase you'll want to google is "time to fixation", and there's some really elegant work on the subject (check out Kimura's 1962 paper "On the Probability of Fixation of Mutant Genes in a Population" http://www.physics.rutgers.edu/~morozov/677_f2017/Physics_67... ) . All of the theoretical results tend to be in generation time, not chronological time, but you get the idea
C is the wrong comparison to make here - it's extremely low level. Java or perhaps C++ would be much closer.

* Ahead of time compiled languages reduce flexibility but allow the compiler to do more reasoning about the system.

* Statically typed languages allow the compiler to reason about the assignments you make and methods you call. If the language is also AOT compiled, you avoid crashing at runtime.

* Dynamically typed languages significantly reduce boilerplate and avoid the mental effort of expressing an idea in a rigorously typed manner. It's the "hold my beer" approach.

disclaimer: I'm a Member of Archive Team who's helping coordinate the joining of Yahoo Groups in preparation for archival.

Yahoo's banning of a large amount of the accounts we were using is a huge setback for us. In total we lost over access to over 55,000 Yahoo Groups, many of these will now not be archived and will be lost when Yahoo deletes everything on December 14.

Particularly disastrous was the loss of access to all of the 30,000 Fandom (fanfic / fanart / etc..) groups that were requested to be archived by members of the fandom community. We're back to square one now, and it is looking increasingly likely that we're only going to be able to re-join (and therefore archive) a small percentage of these groups before December 14.

(And now for the inevitable, shameless plug...) We could really use some help! If you've got an hour or so, we could really use people to come and complete CAPTCHAs for us. (A CAPTCHA is needed to join every group). Instructions at: https://github.com/davidferguson/yahoogroups-joiner
