Yes, we make a significant number of changes to Unreal source, probably on the order of 1-3 per day across the team.

All changes to the engine are required to be wrapped with a special comment tag indicating the author and explanation of the change, so that it's evident in a 3-way merge window how to resolve if there's a conflict at engine-upgrade time.

At a previous company we used Enlighten and Simplygon both of which made changes to engine source, and those were a nightmare to deal with. We had several source branches set up specifically to deal with 3-way merging at all steps of the way.

We also implemented things like instanced skeletal meshes, an improved navigation system, and additional shader passes. Those were all very complex to upgrade especially when Epic had refactored the underlying systems.

We don't use features that are experimental in shipping code.
Hybrids are a gateway. I view them as in the same category as pure EVs, only "earlier technology". I own a hybrid, and I'm 90% sure my next car will be pure EV (3 years from now). I don't know any hybrid owner planning to ditch the electric motor on the next purchase, and know several planning to ditch the combustion engine on the next car.
Or you have a connection pool for every user, which is basically the same except that you must do some mapping by yourself and you have more connection pools and open connections.

At that point you need to consider the whole car. The engine needed to extract energy from that fuel is much bigger in the ICE car. And it also needs cooling, etc.

Comparing just the gas tank to several subsystems of a battery electric vehicle is not really an interesting comparison. The closest comparison at that level is just gas vs just cells.

Overall electric is still lower energy density per weight, but is also far more efficient. The whole Tesla pack has the energy of just a couple gallons of gas but can go 400 miles.
Maybe you can help me out. I went to an event in 2003 or 2004 or thereabouts in London. I'm sure it was called MoogFest. It was due to be held at Turnkey, the legendary music tech shop, but a power cut forced a last-minute move to a bar in soho.

Bob Moog was there. It may have been a birthday celebration. He signed t-shirts. I bought one, but but being young and foolish I preferred the silver print on black, so didn't get it signed. I did shake his hand and mispronounce his name to his face though.

But I've looked a couple of times over the years and I can find no mention of that London event online, anywhere. Other MoogFests are documented, but not that one. I know I didn't dream it because I still have the t-shirt...

What event did I go to?

(edit - here's a mention but it's not very descriptive https://www.radioscienceorchestra.com/bob-moog )
Do demosceners keep secrets like that? I only know of the ones who publish super detailed blogs about techniques, because... those are the ones I read.

Covering actual costs without significant profit is a deterrent. If it costs $20 to register and you ask for $30 I think you're likely to get it.
It'd be nice if it were faster, but considering the usefulness of WSL, I'm cool waiting ~3 seconds for the terminal to load the first time after boot.
> We conveniently ignore that this polynomial is defined at x=0 despite 0^0 not making any sense by ad-hoc defining 0^0 = 0 in this context.

What do you think the polynomial is? I ask, because in all situations similar to this that I've encountered it made sense to define 0^0 as 1, not as 0. If you genuinely have a case where 0^0 = 0 makes consistent sense then I'd be interested in understanding it.

So, what do you think the summation actually is when expanded?
That's what we (mid/small-sized company) with couple dozen machines. It is probably 10% the cost of AWS - but you do need to have at least one person that can handle the servers when/if there are issues.

That one person only needs to devote maybe 2-5% of their time to it (once the systems are setup), so it's still a net gain.
One of the best things about wearing a mask is I no longer touch my face. Without something covering it I rarely noticed how often I would do it.

I’ve also noticed people are less inclined to take elevators with me and takes wider berths when walking. Which are all wins as far as I’m concerned.

The fact it prevents a cough or sneeze from shooting 6ft is also a benefit.
Considering this article is specifically about the math and numbers behind the situation, we need them to use the numbers and terminology correctly.

I base my personal hatred of vim on the first time I encountered it and couldn't escape from it. CTRL C, CTRL Z... nothing worked, I was utterly trapped, I think I may have even had to reboot the system to get out of it.

I buy ebooks because I have intermittent low vision. Large print books worked ok, but the lighting is never right. The ereader has freed me up to read when and where I want to instead of under very specific conditions.

I am also think I am sensitive to the "renters economy" issue. I think I preferred owning them, but I'm not sure why. I've had to dispose of books in various ways in the past for running out of space etc. And I have had books lost or stolen, or borrowed and never returned, so many time. Now I can actually read the books I buy regardless of the quality of my vision. I don't have to worry about running out of space or carrying huge heavy boxes. So I don't know if I really don't like the new way or if I'm just resistant to change.

Karl Popper's the original author of the paradox of tolerance meme.

The paradox isn't "you don't have to tolerate intolerant people because they're bad and tolerance is our goal", the paradox is that tolerating people who then proceed to seize power and outlaw all disagreement with them undermines tolerance.

Unless there's a credible threat, it's a misuse of the quote.

If you're talking about anti-Nazi laws in Germany, fine, but I see the quote trotted out all the time to justify eg twitter banning some alt-right-adjacent nerd for having bad opinions.

I actually don't get Powertoys at all.

They provide basic functionality I would not even class as for power users. Yeah, they are nice, they were nice in win95. Why do I need a separate Program 25 years later to rebind some keys or switch windows, yet every new win10 version tinkers with cortana? People say it would add "bloat", but somehow basic functionality beneficial to many users is bloat while candy crush and xbox whatever is not?

It is just so weird that after decades, basic functionality like bulk renaming files that should be in explorer is still considered a "power user" feature.

While I have no problem criticizing some of their choices and (IMHO) lack of transparency, I do take some issue with the comparisons (not yours) in the text you quoted.

It's true that the death rate is higher, but an often ignored factor is the (differing) chosen qualifier for covid deaths between countries [0].

I am relatively certain that people will be rebuilding old Detroit and Cummins diesel engines in heavy equipment for at least the next 50 years, if not 100.

I have been surprised at how much 40V/80V electric systems are cutting into what was traditionally two-stroke light engines for string trimmers and mowers. The batteries are expensive though, and I don't know how many you'd need to have in rotation to be able to keep one fully charged and ready to go under continuous usage.
This doesn't answer the original question: How could the experimenter ensure the electromagnetic pulse from the nuclear denotation wouldn't create false readings in the TDR measurements?
There’s a lot of discussion here on how (or even whether) a ‘reflectometer’ (I had to look up what that even meant) works.

However, I’m more interested in the things I do understand, and in this case, my question is: considering the fact that there needs to be another (remote) computer to receive the readings, and considering that we’re speaking of processes that ‘degrade’ the cable dangling into the nuclear borehole at an alarming rate, just how does one go about performing an ordinary electrical transmission of data over those distant ranges in those minute times? The latencies are enormous and therefore clearly we’re not talking something like TCP and it’s three-way-handshake SYM/ACK kind of response.

And once the blast approaches the surface (assuming it doesn’t breach it)… is it sufficient for the computer to (comparatively) leisurely transmit its findings whilst it’s in the process of falling into the enormous crater that’s opening up beneath it? Can one presume that the power remains stable long enough for this to occur? (Assuming that the power supply has been destroyed and/or the cables jolted loose, how long does the machine “stay up whilst falling down”?)
The US epidemic did get a bit bigger, into the low hundreds, but they were spread across half of the states. That still looks a lot more like containment than an outbreak which happened to die off.
Burning dead leaves actually does count as carbon neutral. The balance is whether you burn fossil fuels, not whether or not you burn anything at all.
> Which is a project which is born in 2008, and still ship codes from the 90's.

Back in 2008 C++ advocates were saying the same thing: all those errors are only in old codebases, modern C++ doesn't have those problems. At what point should we stop believing it?

> You have nothing that come even close to the complexity, usability and popularity of Chrome in both Java and C# world.

Nonsense. There are dozens of more complex, more usable, and more popular systems written in Java and C#.

> Ironically, even Microsoft uses a C++-core in its software, including MS Office and Edge.

In the older projects that they're most conservative about, yes. Large companies change slowly. Doesn't mean what they're doing today is wise.

> Every industry has domain driven standards in term of coding practice. They all have their reasons based on deadlines, usages, iteration cycle, developer backgrounds, safety.

Which is to say that good development practices will be a lesser or greater priority level in different industries.

> The USA is handling things pathetically

What tangible things is the US not doing that others are?

I don’t see much difference from here in Canada and people seem happy with how it’s going and our politicians.

The main difference I see is the US has a higher obesity problem (30% US vs 20% Canada last I checked) and cities like Toronto are far less densely populated than NYC. Although Montreal is more dense and is having a worse time than Toronto.

I wish we closed our border faster instead of spending a month attacking the US for doing it.

The lack of masks and temperature screening seems to be common among all western countries. And something that seems like a obvious thing to me that could be changed. Our top doctor only started formally recommending masks last week.

I think OP is referring to hybrid ICE vehicles.
The couple of AWS acquaintances I asked about this said that this kind of feature doesn't exist because:

- There's almost no demand for it from the majority of their customers.

- Billing code is a big, scary, tangled mess and also happens to be the one area where you really can't afford to introduce bugs and make mistakes, so meaningful change is already exceptionally difficult.
This is alot of assumptions in an age of paper pencil and telephone.
Agreed. My guess is that's an organizational issue. Some developers at MS would really like these features, but can't get them approved to be in the official Windows roadmap.
In Denmark, which took a different strategy similar to most countries, we never quite had a full lock-down as seen in many other countries.

Majority of retail continued throughout the "lock-down", but with an abundance of care taken in terms of keeping a 2m distance, limited number of customers in a shop (queue stretching out of stores is a common sight), and alcohol sanitizers everywhere.

The majority of businesses and institutions have reopened (schools and kindergardens being the first ones), and restaurants, café and cinemas have just recently opened (with appropriate restrictions).

What is interesting is that Sweden has seen the roughly the same level of economic contraction as Denmark, despite the vastly different policies.
It's a very aspirational target. 25% annualized return (after fees) is a top decile fund. I've heard that number as a target before, but rarely and from investors that weren't used to the market. 12-15% from public markets is a top quartile hedge fund, still a great return but a little less aggressive than the VC number.
But why pass up the opportunity to blame it on brown immigrants?
I have recently moved to a macbook pro for work, having used Ubuntu on my prior machine. In my experience, the mac (despite having significantly more modern specs) is more buggy and just not quite as snappy for these little things. Opening windows, menus, terminals takes longer (even with the swoopy animations turned off). Wake from sleep also takes longer, and a few times a week it is frozen for a few minutes on wake. Maybe I have a lemon.
Sort of. Most "consumer" Linux's come bundled with Gnome and a bunch of stuff too.
Most of the "eBooks" from Z-lib and archive.org I've downloaded are nothing more than poor-quality scans of paper books converted to ePub via PDF+OCR. They're not even worth getting. The eBooks I rent via Overdrive or Kindle, though, were actually prepared specifically for that format.
This is a fair point, although I tend to think (based on nothing other than intuition) that Sweden likely has reasonably similar metrics to its Nordic neighbours?

How to Put More “Character” into Your NPCs
In Australia, we've been told to not wear a mask for a few reasons:

- its hard to wear them right without training, (you adjust them regularly, which means you're touching your face more).

- They can become little virus breeding grounds (if exposed) - they're moist and if virus lands on them it may breed

- they can be very claustrophobic

- masks were in short supply in the beginning and they were needed by medical personnel.

Not a doctor, this is just the reasons I've heard. If more infections occur that advice may change.
* Make a list of at least 50 "jobs to be done" your customer has. Force rank by highest to lowest impact on their business outcome.

* Write out as much detail as you can about your customer in the form of personas.

* Read every support@ email for a day and cluster their problems into groups, build whichever group has the highest frequency.

* Read Mythical Man Month, Softwar, Design of Everyday Things

* Write up what you think the world will be like in 5 years. How does that connect to what you're building?
Touching your face makes not difference at all. Just one of the nonsense promoted by the scaremongers. COVID patients do not sneeze either.

Touching face maybe reduces hepatitis and other gastro-intestinal diseases.

The virus enters your nose via aerosols that will pass through masks just fine.
Yeah indeed. And I think often the perception of AWS is that it's more like Ruby. "It's what everyone uses, so it's a no brainer right?"
I'm Swedish but I live in Scotland and I've been watching the Swedish approach to COVID with great interest. I remain fairly sceptical but I also thought this interview[0] with Johan Giesecke who was the previous state epidemiologist and is advising both WHO and the current state epidemiologist interesting. In particular it seems like Sweden messed up the response in elderly care which is something that everyone is admiting to.

I do think it's too early to say whether Sweden's approach is as bad as it currently looks, likely this is not something that can be measured and compared to other nations for years.

Exactly, our garbage is made up of the most valuable elements on earth, as proven by the fact that they were used to make useful products, eventually we will be mining garbage to extract the value once the cost is cheaper than traditional mining. If we launch it into the sun eventually there will be a resource shortage of some kind.
Out of curiosity, ребята, three questions about Иван Васильевич меняет профессию:
(a) which currency would Shurik have used when buying transistors (~45 minutes)? I'm assuming he would've used regular rubles if he'd managed to find them in a shop, but since he was buying from a dubious looking source (Бери шинель?) would he have needed other currency?
(b) when Иван Грозный discovers the elevator (~24 minutes), is his sign of the cross period, or anachronistic?
(c) as for the pen Милославский gives to the ambassador (~1 hour) ... were those available for rubles?
That, but also a misunderstanding of the strategy: herd immunity works on the thesis that the total number of victims is independent of speed of spreading. So naturally, you'd expect more dead/hospitalized sooner under this (lack of) regime, but also a shorter active period. I.e.: a sharper peak, but roughly same area under the curve.

The reason most countries chose not to do this, is because they expect the peak to be too sharp to handle all the hospitalizations.
The batteries are expensive but when you factor the cost of fuel + oil and the hassle of dealing with it, the case for batteries doesn't look as bad.
