I did mine many years ago, when I had a chance to borrow a still working analog 8mm camcorder with a Firewire output port. Scrounged up a Firewire card for my Linux machine and started recording. The files sit on my hard disk(s) to this day, interlaced.

tape1.dv: DIF (DV) movie file (NTSC)

VLC plays these with the interlace jaggies (on horizontal motion) pretty well masked but you can see that something is going on. Mplayer shows them in their original jagged glory.

Anyone know a reasonably optimal way to deinterlace these (without sacrificing half the vertical resolution) and turn them into some "normal" 480p type of thing? With Linux tools of course. Maybe the article had the answer but it's hugged to death already...
I’m starting to wonder if this is the reason we had some serious problems with macOS and iOS in recent months and years. Serious bugs and serious security flaws.

The A-team was working on getting everything ready for M1. The B-team was working on the usual releases.

If the M1 is as good as everyone says, then that means they had the best people on it.
MacKay assumed that PV modules used in large solar farms would be only 10% efficient, on the grounds that "solar panels would be mass-produced on such a scale only if they were very cheap, and it’s the lower-efficiency panels that will get cheap first":

https://www.withouthotair.com/c6/page_41.shtml

A lot of solar startups foundered on this same mistaken assumption that low efficiency thin film panels would be cheaper than crystalline silicon. Considering costs for cover glass, backsheets, frames, cabling, and racking, that wasn't actually true. Crystalline silicon wins both the "premium" rooftop module market and the low cost ground mounted market. Several manufacturers now offer panels for the utility market with efficiencies reaching 20%, like this one from LONGi Solar:

He palmed an even more significant card at the beginning of the book. Instead of starting with actual per-capita energy consumption in the UK, he estimated consumption for "a typical moderately affluent person" living in the UK:

http://www.withouthotair.com/c2/page_22.shtml

Making the whole population "moderately affluent" yields per-capita energy demand 56 percent greater than the actual value at the time the book was written (195 vs 125):

I thought that MacKay was a clever but not very quiet proponent for nuclear power. His assumptions effectively nudge the reader toward the nuclear solution. Even though some of his assumptions were dubious from the first, and others have been invalidated by subsequent developments, I still love the book for its transparent analysis.
How to build a basic AI music generation system with neural networks
Quick question for anyone using Netlify at work: What's the use case and did you have any issues getting buy-in?
I mean, I literally asked "which ones". You didn't answer. You can't claim I'm ignoring them if you haven't told me what they are.

> I want macOS that has a UI of Windows 95. That would be totally insane on Apple Silicon.

You don't even need to go as far as Windows. Classic Mac OS would be just fine.
Please, instead, let's have something that isn't a shared library loaded into everything. Something usable by contained/isolated/sandboxed software just by giving them a unix domain socket to talk to, with no need to share /etc/shadow.
This is not only Apple. All modern mobile ARM processors, ones that are used in Androids, too, they all are far ahead of Intel in TDP to performance ratio, almost by order of magnitude. Just make bigger ARM chips with more high-perf cores, and they will destroy Intel.
It's not an apt analogy, these are standalone institutions without systemic ties to other parts of the economy, and someone who blows up crypto margin trading is only hurting themselves (or the insurance fund which is sunk cost anyway).

Even if I grant the analogy, their original proposition is accurate. Regulations are the main reason why US exchanges are an incredibly small percentage of total crypto volume.
I'm curious that the A12Z DTK Mac mini shows moderate Geekbench score under Rosetta 2. Is this means some improvements are not M1-only, but already in Ax processor?
Normalizing the data might indeed show that Asian males do even "worse" in online dating. But how dismissive Rudder was of the need to normalize that data was surprising and a bit disturbing as some many people take what is presented as fact and possibly draw incorrect conclusions.
I would not be surprised if normalizing for height did account for some of it, but the data should be available so outside people can run their own tests. (and half jokingly, as someone who wears glasses, normalizing for that as well).

As for education and kids, I can see how that can explain the difference between Asian women and Black women's response rate. But again, need a real examination of the data.

It is a very touchy subject, which is unfortunately plagued by both uninformed people and also those who just want to cause pain to to others.
Yeah, we shouldn't trumpet the tremendous quality of our posts, our insight, our fortitude in the face of immense odds, etc, that would be unseemly...
> I think the intent is to calculate medians on longer running streams of data than that. Why would you even use this algorithm for 5 values?

I don't know if you realize but these kinds of comments are incredibly frustrating to respond to. It's like you didn't even try to understand the comment before replying. I was not saying "it's terrible because it easily fails on 5 elements". I was saying "it's terrible because it easily fails, and to illustrate, here's an example with 5 elements that will help you understand the problem I'm talking about". Does that make sense? Surely it's not rocket science to see that the number 5 wasn't special here? Surely you can see how, say, if your list starts at 2E9 and goes up to 3E9, the exact same problem would occur for the billion-element list, and hence that my gripe was probably not about 5-element lists?

That is a surprise as seems Apple even response to the news. Can anyone else confirm the story. Like the old day RFC you need two implementations for paper publishing in the ietf.
Well you can't really expect those kind of solutions to scale. Burning a few bits of paper is small enough that you don't really need to worry all that much though.

> If the adult they are crossing with is trying to sell the child in the US, then having the adult and child detained together still prevents this.

Until the detention is over and then you release them together?

One threat model is child abuse. Detaining them together enables abuse. Another threat model is deceiving the government about the child trafficking. Separating the child and the adult allows investigators to question them separately without the adult coaching the child when investigators are not present.

> Also, at $250 for a paternity test, wouldn't a cost-benefit analysis make it rational to do that rather than risk the (more expensive) harm of separating a child from their parent?

This is a good point but not all children are biological offspring of their legal parents. When you suspect trafficking and the adult claims the child is adopted what do you do?
This is literally one of the primary reasons this was designed. Imagine having to monitor several instances of PRTG, Solarwinds, Vectra AI all at the same time and action multiple issues for multiple customers. All while sometimes spending all day onsite at customers or in the datacenter. Applying a SOAR strategy to SIEM can sometimes only go so far.
High leverage means less counterparty risk because the max loss is the capital residing on the exchange which is much less than the position size.

As far as mechanisms there's auto deleveraging and insurance fund.

Professional traders all wish to be on exchanges with high leverage because it means more volume is uninformed flow and therefore there is more alpha on the table. The pie is bigger.
Maybe say that then, instead of "for any other purposes whatsoever in perpetuity".

I tried to link a new bank account to paypal recently and they tried to get me to let some third-party log into my bank's website on my behalf. After finding the tiny "No thanks" option (which inexplicably required running said third-party's JavaScript on my device) I was ultimately able to do it the old fashioned way but this process, as they warned, took 4 days rather than being "instantaneous." I think a lot of people are still bullied/tricked into sharing credentials with all manner of skeezy websites.
And that one wasn't also an ad for an email service.

Negative numbers were hardly distrusted in Indian mathematics - Brahmagupta in the 6th Century just asked called a negative number as "debt". (see for example, [1])

The real question is why negative times negative is positive - I had this doubt in school. I am a bit ashamed to admit that I still don't know any "from first principle explanation" for this fact.

I think the beauty of the iPhone lies in its elegance, but I suspect I'll always code on my Linux computer.

Nope. Regular usage at around 17-18 gb ram.

Certainly everything you say is true for our genetic chemistry, but I don't see a reason why that is necessarily true for all genetic chemistry. For example, our data storage for computers scales from megabytes to gigabytes very well. There's no reason to think there aren't other solutions that scale just as well.
no it doesn’t, unless your subjective opinion says these two are in fact indistinguishable in which case you would have to explain the reason for the semantic collision of “placing a wager” and “cracking a joke” and how these two completely different constructions came to be used to describe literally exactly the same set of phenomena.
I agree. Also, isn't the Kyoto protocol / carbon credits thing a very similar concept? Cmiw

On the other hand, there are 40+ million U.S. citizens, of African origin, each with at least one ancestor at the bottom of the Atlantic due to the capitalist trans-Atlantic slave trade. Enslaved for four centuries, building capitalist America literally with their bodies as some of the first U.S. millionaires earned their millions from intercontinental human trafficking. There are roughly 5 million Indigenous U.S. citizens who were subjected to the continued oppression unleashed by an exploitive capitalist system. Can we talk about the 627,000 Vietnamese citizens brutally killed by the U.S. military during the Vietnam war? They didn't make it out alive.
Thanks for the feedback. If you have ideas get on them!

Sounds like this solves the easy part (getting to high altitude), but makes the hard part (getting to orbital velocity) even harder.
Remember when you could reboot your computer without rebooting your phone first?
Nobody seems to mention this when comparing, but code to handle the case of getting a bad error code is almost always very poorly exercised: therefore, buggy.

That is in contrast to the code run during an exception, the destructors, which run all the damn time.

If you do make the effort to test your error-handling code, that is a significant expense on top of the reduced performance. Maintaining those tests as the code changes from under them is another expense.
I just had a lightning strike that destroyed a mid 1990s era somfy DSM controller. The cost to replace the entire system is 11K.

I havent done any experimentation, but are there any wireless replacement boxes that can activate the motors?
Went to a meeting of hams. All ancient guys. But they had awesome stories about being in Florida after a hurricane.

Basically a ham guy would stop in some small town, and for a week he was the ONLY way to communicate with the outside world.

One guy needed energy medication. He was talking to a guy in New Hampshire who could use the phone to call another Ham who could access others in Florida via ham radio. So guy got his medication, through a bizarre chain of hams all across the East coast.

There were a bunch of stories like that. Then the more technical stories of how to setup a minivan for extended trips without access to gas electric, etc.
I hope it works because it'd be rad, but at $500K per 200-lb payload, they'll cost $2500/lb. That's only half as much as SpaceX Rideshare for the same size payload, today. If Starship works out, then SpaceX costs will drop enormously.

Fuel is a minor portion of launch cost. SpinLaunch is saving fuel but throwing away rockets; it's going to be hard to compete with someone who throws away more fuel but saves the rockets.
A lot of people think that less than maximal performance is sacrilege though, which is why people are already complaining.
>Weight 10KG MAX

The goal weight is 60% of the way there. Rounding to 50% for convenience, that means the prototype is around 20 kg or basically the weight of a large barbell plate. Imagine typing with that on your lap!
For most non-techies, buying a router means hours of fiddling with an inscrutable setup ending in failure, then either giving up, or if you can afford it paying the Geek Squad to set things up for you.

The advice I give most people is to use whatever the ISP provides, so that when things go south the ISP is on the hook for support.
Ugh yes, this is infuriating and happens all over the place. And combine it with sinusoidally tweened animations where it often looks like the tail end of the animation has finished before it really has, making it easy to mistime your inputs so they they’re dropped.
Not fake news ?!!!! Wow
Thanks, that is very enlightening. So Tether are all about maintaining the apparition of a 1:1 backing of USD to USDT. It's the lynchpin of the whole scam. Otherwise the step above you mention around the arbitrage bots buying btc-usd no longer occurs, and the game is ruined for them.
Oh wow, I was wondering why bother building housing around it. That seems incredibly expensive to build and maintain.

Your comment is very on point. If they slowly even out the atmosphere, they loose the speed. So they'll need to coordinate the door opening at exactly the right moment. And if it doesn't the whole instillation goes boom.

I feel like it would be better just to use the money to buy more rocket fuel at this point. This is so much alike to "game changing ideas" like the hyperloop, solar roadways, and other "disruptive" tech that make a cool headline, but break down the second you think about the real world logistics and cost.

I hope they prove me wrong if they can get it to work though, cheaper space flights could help the world in so many ways.

But one can choose to ignore fashion and wear comfortable clothes.

Apple has chosen to make everyone live in its crazy world. Letting users skin the OS would be a better choice.
I'm surprised they're getting rid of long held keyboard shortcut conventions though. Previously, modal popup options (i.e. for saving docs) could be selected via Option-letter, i.e. "Save _a_ll" could be selected with Option-a. Their new popups which may or may not be prettier force you to either use the mouse or turn on "Use keyboard navigation to move focus between controls" globally and tab around. Neither of these options is as elegant as being able to select what you want with a single command.
You've completely changed the scope of what's being discussed, though. Retain/release being faster would just surface as regular performance improvements. It won't change anything at all about how an existing application manages memory.

It's possible that apps have been completely overhauled for a baseline M1 experience. Extremely, extraordinarily unlikely that anything remotely of the sort has happened, though. And since M1-equipped Macs don't have any faster IO than what they replaced (disk, network, and RAM speeds are all more or less the same), there wouldn't be any reason for apps to have done anything substantially difference.
That’s a good question.

I use the iPad for some work (editing photos, email, etc) but mostly I use it for entertainment. I’m using it now for web browsing, I watch TV/movies on it as I don’t have a TV and don’t always want to use my projector/screen setup, and I do some light gaming on it occasionally.

The laptop is for work, which is photo editing (again) video editing, design work, word processing, light web development, and various other business needs (accounting, spreadsheets, etc).

I’ve tried to switch to iPad only so I don’t have to cut out entertainment completely but almost everything work related is slower and more annoying on the iPad. So I end up with both.

As another commenter above mentioned if the iPad ran OSX I would probably just have the iPad, but here we are.
> Typically speaking waiting periods are about reducing the risk of someone in a crisis purchasing a firearm and immediately using it for harm, usually either suicide or domestic violence. From a public health perspective there is very little increase in danger for someone buying a second gun, especially of the same type. All of the risk is for their first firearm.

This assumes that people don't get rid of firearms or have changes in mental health. There doesn't seem to be much of a justifiable reason to get a gun on short notice, so why not just apply it universally?

> If you're pro-firearm, there is very little difference between "you have to register your gun" and "you have to register to buy a gun".

I'm pro firearm. I'm also vehemently pro education. If you need a license to prove you can safely operate a motor vehicle, you should need a license to purchase a semi-automatic weapon IMO.

I disagree, there is a functional difference between licensing gun owners vs registering guns. One tracks that an owner has gone through training and is authorized to purchase certain types of weapons. It doesn't concretely determine whether they own, or have ever owned a firearm, just like a driver's license does not determine that I own, or have ever owned a motor vehicle (just that I was able to borrow one for the duration of my practical exam). Further, mandatory registration of firearms would include things such as purchase date, serial number, model, location of purchase, etc., which is actually new information that could be potentially used to track and confiscate firearms under certain circumstances. I'd also like to point out that a background check gives more info about the purchase of firearms than a license would. It tells: the date of purchase, the rough type of firearm (handgun vs anything else, at least in WI), and the location of purchase.
I have this on on a second monitor, and it really reminds me of New Year's: the colors, the random movement caused by the flames, the multiple views, and the lack of plotline all make it seem like a stream of Times Square on December 31. Y'all should bring this back then to give 2020 a proper sendoff.
Strikes me that a lot of the feature set could be useless- what is really useful about the metrics? Lot of spaghetti at the wall. However, a company that tries to use the useless will be a bit more demoralizing and ineffective.

I wonder if the real goal somehow is MS collecting data that can tie into Linkedin data.
> Meth is such a gross dirty drug, I often wonder if Cocaine were legally available to drug users if Meth ever would have gotten a foot hold.

It's dirty due to illicit production methods.

Methamphetamine originated as a pharmaceutical (Schedule II in the US), so it does exist in a "clean" form.
I don't know about this particular algorithm, but I believe some similar approaches only converge if you're estimating on values from some stable or slowly changing distribution. A monotonically increasing series would not be a good fit (nor a small dataset).
Your response tells me you definitely are the type with the talent to solve it, but yeah it will require some brute work but I’ll think you’ll come out of it a lot stronger (and help your team a lot). “tsc — extendedDiagnostics“ is a great place to start. tsc --traceResolution > resolution.txt. both from the OP. I’d get a book pronto on advanced typescript as well. Create a tiny Ts project from scratch and use that as your comparable. Measure your progress and have a beer or ice cream every time you make a jump. I worked on one huge typescript project years ago at MSFT with slow compile speeds, and was always too scared to try my hand at fixing that, and sort of regret it (though it was a hard problem since we were on windows ;) )
This though isn't as clear cut as it seems. Need to normalize for born in America and just got here a year ago. Rudder doesn't normalize the data.
it depends on if the how is functional or espistmelogical.
So now Microsoft is selling four products. Once, you pay for the "product". Then they sell YOU three times: to whoever is buying all this W10 and O365 telemetry; then to the government who's paying for a feed; and now to your boss.

4x revenue? Buy Microsoft stock.
Cool. I didn't mean to bash your product, it's neat! Just think it'll be a tough sell unless you can either really commoditize it or alternatively enhance it into a premium, high-end product. (The bespoke option might go some ways to that, but you'd also need very high end materials, finish, design aesthetics, other unique features like concealed, built-in wireless charging, etc).
