The author has clearly an opinion. I am getting more and more the feeling, that IT is a field where opinions are strongly hold, mostly because of past personal bad experiences, and not with much evidence.

There are many ways to approach a problem, and there are good and bad ones, but often you have to make a trade-off. I would appreciate a more differentiated view.

The author makes the math on "high cost of maintenance windows", but leaves out the expenditure side to it. And what is the hand-rule for adding a nine behind the availability? I vaguely remember exponential cost increase. "No downtime, ever", requires next to infinite cost.

The author suggest a false dichotomy. You can have maintenance windows and while aiming for zero downtime.
The maintenance window serves the customer a higher predictability on when to expect failure.
No failures are obviously preferable, but it is never the question if to cause failures or not, but where you spend your resources on.

>“In addition to Mr. Diaz, three other witnesses (all non-Tesla contract employees) testified at trial that they regularly heard racial slurs (including the n-word) on the Fremont factory floor. While they all agreed that the use of the n-word was not appropriate in the workplace, they also agreed that most of the time they thought the language was used in a ‘friendly’ manner and usually by African-American colleagues.”
That guy is really good. He reminds of the Andy Kaufmann character, Latka, from "Taxi". He has great interviews on Youtube as well.
>>Presenting your own editorialized conclusions is not the same as providing a primary source.

This is a discussion forum. You seem to have an axe to grind with me that's motivated by more than just what I wrote. Are you this non-charitable and critical of those who are sounding the alarm about COVID? This double standard, motivated by political preconceptions, is how dissenting viewpoints are suppressed, and only one viewpoint - that of COVID hysteria - is allowed to express itself.

>>The proof is that you've tried to pass off a study on the quantification of the real world correlation of symptoms tentatively linked to long covid as, somehow, proof of a causal relationship, even though nothing of the sort was suggested.

To clarify, my criticism is of the many who are in fact taking these preliminary results, and drawing the conclusion that long-COVID is afflicting one third of all COVID patients.
Not that much, surprisingly, especially if you control your IDX points like China.
I agree about the PoCs stacked on top of each other and the thousands of CS man hours required to transform it, I don’t think I could have said it better.

There’s some really really neat projects in the Julia community though, and some super smart and very hard working people. I’m wondering if some focused effort from the community guided by the stewards of the language may yield promising results? As opposed to letting people that are interested in a topic just naturally contribute?
Also it’s really useful if you are in a car - getting directions, calling people, texting etc without touching your phone.

Sure lots of cars have this already with voice, but Siri et al are much more reliable at it.
Yes, believe it or not, it will try to call itself, and fail.
That sounds like some sweet consulting money.
You just killed number portability when switching carriers.
> your average Chinese American shouldn't be the subject of racist discrimination

Yet you're arguing for precisely that. Discrimination is bad, unless it's done in the name of national security, which will be defined by people who have an extremely aggressive, clash-of-civilizations foreign policy vision.

Same. Using it to add things to my shopping list is useful too.
If there was a vaccine for cancer, it wouldn't matter to anyone else if you got it. This is a virus. It's a public sacrifice. As brutal as it sounds, you and I and everyone we know had to line up against a wall, and some people were going to take a bullet for the team. I went in prepared to do that, rather than deluding myself that the virus wasn't real or that it was avoidable. When my uncles were in the Navy, they got pumped full of everything at once through an airgun in the bicep. This is jury duty, voting, your DMV test and your military service rolled into one. It's the price of living in an advanced society. I'm sorry for them - and I hope they recover - but they should be considered a hero. This is simply under the circumstances the only right thing to do.
SpaceX is clearly doing much better, still I’m not sure just parroting your competitor is the way forward. There are different approaches and just mixing them blindly can’t work.

Many of the things sound about right in many ways in Blue Origin. Keeping hours sane. Pay not stock. Careful design. Clearly something doesn’t gel, but just saying “oh maybe Jeff Bezos should be more crazy, and how about we set up an electric car business on the side” is counterproductive IMO.
Never Use WhatsApp/Facebook for Business Communication
Yesterday I was traveling from Bangalore to Chennai. Suddenly I was unable to send/receive WhatsApp messages. Initially, I thought there was no phone signal, but soon realized that it’s not a network problem, but Facebook, Insta, and WhatsApp are down.

The outage knocked every corner of Mark Zuckerberg’s empire offline on Monday. The company’s family of apps effectively fell off the face of the internet at 11:40 am ET, but what was Facebook's response? Just a simple tweet :-) saying- “working to get things back to normal as quickly as possible.”

Can we really depend on Facebook products for business communication? Here's my take after spending 2 years & building a product that uses Whatsapp API.

https://jikoo.io/blog/neveruse-whatsapp-for-businesscommunication/
Any boolean function can be represented as a polynomial over the integers modulo 2 (that is, its algebraic normal form).

Modulo 2, AND is multiplication and XOR is addition. We also have the useful properties 1+1=0, x+x=0, and x^2 = x. Thus:

NAND(0, 0) = 0*0 + 1 = 1

NAND(x, y) = x*y + 1

AND(x, y) = NAND(NAND(x, y), NAND(x, y)) = (x*y + 1)*(x*y + 1) + 1 = x*y + x*y + x*y + 1 + 1 = x*y

XOR(x, y) = NAND(NAND(x, NAND(x, y)), NAND(y, NAND(x, y))) = (x * (x*y + 1) + 1) * (y * (x*y + 1) + 1) + 1 = (x*y + x + 1) * (x*y + y + 1) + 1 = x*y + x*y + x*y + x*y + x*y + x + x*y + y + 1 + 1 = x + y

Since both AND and XOR can be obtained from NAND, any polynomial can be constructed. It also becomes obvious that you can't get x*y from x+y and vice-versa, so neither XOR nor AND can be universal gates on their own.

NOR's algebraic form is x*y + x + y + 1, from which you can similarly derive AND and XOR. XNOR is x + y + 1, from which AND cannot be obtained.
The important part here is to use the right benchmark for human drivers. Crash statistics are heavily skewed by drivers that are speeding or under the influence. That can be the right benchmark to show how AI driving can help in certain circumstances, but they don't show why most human drivers should be replaced.

Taking those out and considering assistance systems in new cars (which already work quite well), AI has to perform incredibly well to drive safer, especially if it can only drive in easy weather conditions.
I am 100% opposed to this model. I am even opposed to Automatic Deductions

People should have some "skin" in the game of taxation, if we allow the process to become seamless overtaxation becomes a real problem.

Even today people do not treat their Gross income as their income, they look at net. This is the wrong way to look at it.

I believe people should have to physically pay the government every month just like you do your water bill, your groceries, etc.

If people had to write a check, or trigger an electronic payment to their local taxing authority every month there would likely be more focus on where that money is going, and why the government things they deserve a huge chunk of my income (hint they do not)

This prevents the government from just raising taxes and hiding these increases.
In all fairness, the previous versions didn't post correctly; they were never visible (you can verify this). I think it was an issue caused by the temporary outage yesterday.
Market failures are real, and society is poorer if we churn through more stuff that breaks instead of less stuff that holds up.

Ideology is a mind killer -- if this weren't attached to the word communist you'd probably be agreeing, yeah, too bad people won't use the durable glasses and waste energy replacing less durable ones.
I have the same. So I stopped using it. Almost a year now since I uninstalled FB, and a few years for Twitter. It's amazing how you don't miss it.

Now if I could just shake my HN addiction...
In most countries in Europe (not only in the EU) you can download the official software from the corresponding tax authority. In many places you don't even need to send hardcopies of most documents - at most some printed page with a code and your signature. You must of course keep all the documents on which you based your tax returns in case they ask you specifically for them.

I have a strong internal voice and wondered what is was like to not have one. People describe reading and not hearing the voice and this sounded strange to me.

Then I noticed that I don't think with my internal voice when coding. I'm still thinking but not with sounds in my head. That blew my mind and made it easier for me to understand other's internal experience.

I wonder if people who rarely have an internal voice are less interested in things like podcasts, where the information in conveyed aurally.
> Because of this I have almost no energy bill. It was expensive, though.

The house I grew up in, in the UK, was never re-sided, re-roofed or required its exterior re-painted in at least 200 years and parts of it 600 years

These cheap houses built in the US create a lot of maintenance and waste. Siding/roofing seems to need to be replaced every 15 years or so

Some friends are just going through the process of re-roofing. I asked them about going with a metal roof, or some other kind that might last longer. Their attitude was they don't plan on being in the house that long. In 15 years it'll be the next owners problem
I pretty much continue self-study every time I stand corrected.

Things learned from junior hires: a lot in RF domain, opamps, 74XXX trickery, signal integrity measurements, fiddling with high freq PCIE, DDR, PAM4 lanes in the sciency way, and whole new world of advanced power electronics, and designing it according to standards, and codes...

MIT Abandons Its Mission. and Me
I wouldn’t put nails in the decentralization coffin yet. The Internet isn’t really that old, and it’s a complex topic.

Technical platform decentralization is hard for technical reasons and the Internet may indeed contain a bias against it, but physical decentralization (telework, geographic diaspora) is a decentralization prediction I see starting to happen.

Physical decentralization was underway before COVID. The pandemic just accelerated the trend by years.
The families of those wrongfully killed by police get a lot less then that, $137M is just nuts.
> I would add that the NOR gate is also functionally complete.

Yes, one good example being the Apollo Guidance Computer [0], which was constructed wholly using NOR gates.

Works well for playing radio stations too. I also use my Echo to control my FireTV. Nice to be able to pause and grab something without hunting for the remote.
Fwiw, starting in iOS 15, Siri will process speech on-device, which is huge.
oh, I forgot to say, in some countries you even received them already filled in.

There are a few companies that build such houses, like bostonhaus.de and whitehouse.de .
Siri and similar voice assistants work really well as an universal remote control.

Right now I can ask Alexa to open or close the curtains, to start cleaning my house, or to play some music or podcast — all without having to find where my cellphone is or risking getting trapped a couple of hours on the internet.
It depends on the kind of accident. Currently, accidents are also treated very differently depending on intend and the likelihood that this fault would've been made by other drivers. I assume software will be judged under the same circumstances.
> Maestro cards can't be used for online payments

They can, for example ~15 years ago I used a maestro card to pay for a subscription to Sony. All they needed was a card number and an address (the latter for tax reasons, that is mandatory).
But we asked Siri if it was going to rain, it said unequivocally no, we didn’t take umbrellas or raincoats and it rained. We got soaked :(
Looks like this part is political:

The most fascinating physics nobel prize for me in recent times was for gravitational wave detection using LIGO. I spent days learning and watching videos of the three of them. The ingenuity of the detector is fascinating and the fact that every year they simply got closer but ‘not there yet’ and the fact that it took more than two decades says that the goal was probably secondary but they enjoyed the journey far more. Of course they would have hoped to see the waves be detected in their lifetime but for Kip Thorne it was 50 years from the start. Most of the stories behind Nobel prize winners are mind boggling.

I've switched completely over to a well-moderated mastodon instance and haven't looked back since. Finding an instance that aligns with your values is the tricky part but once you have done that it's a lot of fun. The absence of any advertisements or algorithms really has an impact on the quality.
Here is a nice summary: https://twitter.com/thePiggsBoson/status/1445334496857841668
If you are building a CMOS 2-input gate then both NAND and NOR use 4 transistors. (2 NMOS and 2 PMOS each)

The reason NAND is preferred is that NMOS transistors have roughly half the resistance of a PMOS transistor of the same size. This means that to get a gate with pull-up and pull-down networks of equal strength (which is usually desirable), the NOR gate needs very large PMOS transistors and tiny NMOS while the NAND gate has all of its' transistors equally sized and relatively small.

The result is that NAND gates are smaller in size and slightly quicker than an equivalent NOR gate.

Almost everyone's memory seems to get noticeably worse with age, so almost everyone complains about it from time to time. Also, stress and lack of sleep can temporarily impair memory. So it's probably not Alzheimer's!
That's the case with all mainstream operating systems. You can't go and change a program's binary data while it is running without blowing stuff up. As a result, Windows locks executable files for write/delete upon startup and releases the lock upon exit of the last usage, and unixoid OSes warn you to restart applications after an upgrade.

The only environment other than maybe mainframes that supports hot reloading is Java and that has limitations.
I don't really have a binary answer for that. Sometimes yes, depends on the type of thinking being done.

Everyone on my team is in the 35-45 bracket. We've been at the same shop for 5+ years. I think the unsaid thing is none of us are going to leave because we're all to old to be hired anywhere else.
I've recently been wondering about the opposite. Maybe the whole Internet should be brought down for a couple of weeks a year, so that society can't become totally dependent on it. Your thermostat shouldn't require a cloud service to work!
Not that I think you will change your mind but here is the study: https://www.nejm.org/doi/full/10.1056/NEJMoa2110345

"During the blinded, placebo-controlled period, 15 participants in the BNT162b2 group and 14 in the placebo group died; during the open-label period, 3 participants in the BNT162b2 group and 2 in the original placebo group who received BNT162b2 after unblinding died. None of these deaths were considered to be related to BNT162b2 by the investigators. Causes of death were balanced between BNT162b2 and placebo groups (Table S4)."

Look into statins if you want to understand bias and corruption in clinical studies.

Giving a medication to over 20,000 people and not saving a single life in 6 months is pretty weak. An NNT of over 20k is unheard of. Anything above 10-20 (not 10k) should make people at least be allowed to ask questions.
High profile prizes will always be political. That said, Syukuro Manabe built the foundation for a lot of modern day computer-based climate simulation. I can't speak for the others but I'd say that's Nobel worthy.
What was the previous fee?
I agree that the experience is extremely off putting. But having been in the community for almost 5 years now, I have to say there are super awesome lovely people that are mostly silently working in the background and very hard at that. The loud minority unfortunately is grating, and I do wish the stewards of the language established more strict guidelines on conduct or philosophy of the language. I don’t want to name names here, but when prominent members of the Julia community bash other programming languages while ignoring the painful friction in Julia, it comes across as very tone deaf and in poor taste, and does set a bad precedent.

I think having a weekly what’s great about Python/Rust/Go/Zig and how can we port this to Julia would be awesome, instead of the weekly gripes about Python/MATLAB/R.
You'd have to control for potential confounding factors, like the psychosocial effect of COVID, and the two weeks of total physical isolation every COVID-positve case is subjected to, to even begin to start drawing the conclusion that COVID infections are causing a significant fraction of these self-reported symptoms.

Almost every symptom listed could be a result of anxiety, which in turn can be a result of the extreme fear that is now surrounding COVID.

And this is only text messages, which still have light years to mature.

Obviously Facebook Marketplace is worth billions. That too will need protocols. ( Gaza Marketplace - https://www.facebook.com/marketplace/107601032603195 )

This is one of those slippery slopes, but I dont think the uses here have gone down that slope yet.

An open ended search might be on terms related to bomb making, where curiosity might get someone labeled a potential terrorist. Here a specific person went missing and they were looking for people who searched on that specific person. It's still a net, but it's not that wide and its focused on something that already happened. They even put date ranges on the search.

I see the problem though. It's probably just a matter of time before the specificity is loosened a lot, and that would be bad.

Once upon a time this would have been the norm. If we were performing any DNS related maintenance we'd drop the TTL to 5 mins a day or so before the maintenance window was due to start. Once happy we'd not broken anything then we'd bump back to 21600 or whatever. But I guess the move fast/break all the things crowd no longer have any patience for this kind of thing.
