I think this observation is very much on point. Imho, there's a bit of what amounts to fetishism in the knife-making community about steels. Truthfully, the primary differences should be in fit, finish, and balance for a knife. It's just as possible to put a fine edge on the cheapest steel in the world as as it is an expensive tool steel like 440C. Jay Fisher, a custom knife-maker, likes to makes the point that a ceramic flint-knapper can put an edge on a stone that will scare any knifemaker alive, as long as the edge doesn't accidentally touch anything too solid and chip.

An AUS8 blade hits a nice balance between corrosion resistance, end-user servicing, decent maximum hardness, and manufacturability, though focusing on "our steel is special" seems to sell blades. Plus, I think it's worth noting that if most manufacturers were to make blades out of more expensive knife making steel like S3OV, not only would they likely corrode, people would be close to incapable of properly caring for those blades properly anyway. It's not an easy task, especially for someone who is only using the knife to achieve their primary goal: cooking.
Ask HN: Understanding Video Streaming and CDNs
I have been looking for sources for understanding how video streaming works and what parts CDNs play in making content available. I have not been able to find any sources which provide an in depth insight of the above things. Can someone point me to such sources ?
substitute rich with power and you have exactly how it plays out in China. uniformed people being in charge of those not in uniform. it will be more civilized in the West, but never for one second assume that a filthy cop who is usually happy to abuse the system when it comes to making parking tickets disappear for friends and family, or who is using the system to stalk a prospective date, ... there will be plenty of situations where if you have power you get to wield it.
You don't have to go that far.

Anyone wanting to abuse the information (i.e. a criminal) would not really care to commit a crime by reidentifying so this law would only prevent people who want to help from doing so.

In the end the are always intelligent criminals (or foreign countries acting against your country for their interest). So you will always be able to buy deanonymized data on the black market. Even more the people doing it for that reason can include leaked/stolen datasets to do deanonymization invested if just public data making it potentially much easier.
I love to work in python and I came here just to point out that it's pretty obvious one should not use it if raw performance is a concern (which is not in many situations). I remembered this Cal Henderson talk at Djangocon:

https://i.postimg.cc/Dy81R2QQ/yourmom.png

That said, I wrote a bit of Go recently and the experience was pleasant enough that I'd consider it for future works (should the needed libraries exist), as the extra performance and ease of deployment comes with very little effort from the developer.
I feel that lately there is a lot of politics involved in these issues.

China has taken drastic measures of quarantine and they seemed to have worked reasonably well: the bulk of the cases have remained in Wuhan and Hubei.

That seems to created a political issue in the West with, I feel, a lot of reluctance to be seen praising China or copying China because the Chinese government is the boogeyman.

Certainly in Europe it seems to me that governments are neither prepared not willing to take decisive measures, or (like Italy now) they start taking them late.
The references I have found for "the recent news that the study showing that it could be transmitted by asymptomatic people wasn't correct" are all over a month old, while the references I find for asserting that new evidence is confirming asymptomatic transmission is in fact happening are only a week and a half old. Can you help disambiguate?

You can't really stop a virus. But on the bright side, in France only 11 persons have died of 949 infections. In Germany no one has died despite 800 infections. That indicates that with access to proper medical services the death rate is actually quite low.

Find stats here: https://www.nytimes.com/interactive/2020/world/coronavirus-m...

The death rate for European countries is about 0.7% at the moment.
I often use the VCS feature of PHPStorm where I can select a piece of code and then immediately get a nice list of all the commits that changed that code. I can then double click on that code and get a list of other files that were modified. For example, I can then figure out why a certain piece of code does what it does, and why it was added.
> I think I'd prefer the way of acting of the Italian government who at least seem to be trying to do things.

I understand that Singapore is a very small country and ran way differently than my own, but please look up what the PM there said when he addressed the country on COVID-19 matters and compare it (if you can find a subtitled version) with what our "Giuseppi" said. A world of difference.

Of course now they must do something. But way before the outbreak, local administrations of the now-locked regions who asked for quarantine controls from people from Wuhan and China in general were called "Sinophobes" and the government was far more eager to lock down direct flights from China (useless if you go via hub) as opposed to quarantining or at least tracing those people, and of course to show all support for Chinese people. (Note that I do not condone Sinophobia at all: but a matter of public health policy - like everything, improvable - was just framed as racism).

Ok, this might have not helped at all given that the current theory is that SARS-CoV-2 came to Italy from Germany. But the government was too eager to return to the "important affairs" (meaning, discussing whether a member of the coalition would leave the majority or not). Then when the first cases arrived, there was a total "tug of war" with the legislation ("close down", "ok, maybe not", "maybe yes", "SHUT DOWN EVERYTHING").

So nothing Singapore or South Korea-like. COVID-19 worries me, but I'm far, far more worried about this government.
Measles have lower lethality then coronavirus. You also did not had whole population exposed to it at the same time. You can get them only once, so even when kids get sick, adults around wont.
How to detect a blind apple supporter?

- He says, Apple is pro privacy
- He redirects systematically with some 301 all monopolistic apple moves to Facebook concerns or Google.
- Finally he has a fallback gateway when discusing "don't buy apple" if you go with "I want to be free about that thingy in my iPhone"

Apple is pro Money, and all it does is 2 things now :
- More Money
- Brand image building, apple is PC , apple is the PC Fraternity of southPark haha, and blind supporters are its members.
How would you time the excess time slots?
What site in particular are you having trouble with? I haven't found a single problem in the few months it's been released.
You would still have to read the entire JPEG in though, wouldn't you?

I'm not an expert on JPEG, but I think that if you want the macro blocks at the bottom of the image, you still need to un-Huffman the all the blocks before it to find where the macro blocks start (since AFAIK there isn't a table indicating where each block starts). That means you have to read the entire JPEG from storage, only to through away the vast majority of it.

Even if there was a way to magically predict where the low frequency values of the image are stored, you'd still have to do tens of thousands of random reads to just get to them. Reading the whole file would be faster.

So if you have 500 photos and you want to go though them and need some thumbnails, for non-progressive image thumbnail generation, you have to read 10 MB x 500 images = 5 GB of data, but with a progressive thumbnail you only need the first 100 KB x 500 images = 50 MB of data.
> Tonight a pdf of a draft of the above document has leaked

I'm surprised people are surprised that such a thing leaked. This has been going on for years, except, no one batted an eye.

> We are Italians and we are unable to respect the rules.

As an Italian too, I don't like this generalization. You can make people more willing to follow rules if you approach them correctly. Going full-paternalistic mode (like this government has been doing) or even blaming them ("don't play dumb", is that something one would expect from a PM?) isn't going to help.
Yes! I performed a major refactor that lasted about 6 months. With the commit history (that linked to tickets with discussions and even mockups), I could understand the process of people who had left the company two or three years ago. It allowed me to tell obscure business logic from leftover code and bugs. I could trace each line of code to its requirement.

I also used it to pinpoint the cause of a bug after updating a docker image, knowing that the bug was introduced in a certain file between certain dates.

Now I try to strictly enforce detailed tickets and ticket numbers in commit messages.
Safari ships with its own Reader View.
I use gmail the same way. I do feel that the search functionality could be improved though which I find ironic.
All the time. If I'm reading code and think "why on earth is this here?" the first thing I do is hit the git blame page on GitHub.

If a project has a clean commit history, this instantly gives me extra context and hopefully even links me to an issue thread explaining what was being solved.

In older code bases this is invaluable - I often find myself looking at history from five years ago or more.

It's also great for my own projects. Even if I wrote the code six months ago there's still a strong chance I won't fully remember the context for the change.
Inbox zero isn’t deleting everything, it’s archiving those that are done so they aren’t in your immediate inbox.

> We need to make it cool to work in a semiconductor company.

I am not optimistic. "Semiconductor company" ==> high capitalization (expensive processes) ==> fertile ground for lawsuits and attacks.

As long as a slightest mistake has a potential to turn into multi-million-loss lawsuits, it will never be cool. Is it easy to be cool walking a tightrope between two skyscrapers? Not for many I'd guess.

BTW it is the same for non-semi companies (like OEMs), except that volumes of a given single product are generally lower, so mistakes are more bounded.
Anecdote time. I had a psychedelic experience not that long ago with professional guides in a place where it's legal. At some point when tripping I became very aroused. I felt like I would agree to any suggestion of intimacy at this point. I was still aware of it, but it took a lot of self discipline not to initiate improper contact with my guides myself.

The whole guided trip was an amazing experience and I am glad I have done it. Guides were very professional and made me feel safe. However, the potential for sexual misconduct on both sides is something that is not really being talked about, but needs to be addressed.
> There is a phrase in China for the way such tensions are manifested: when everyone denies all responsibility and tries to shift the blame back onto the blamer, they are busy ‘throwing woks’.

I appreciate learning idioms of countries foreign to me, and in this case it makes for a great article.
> Chrome used to run different tabs as threads of a process but that ended since Spectre and Meltdown. Back to single process since then.

Chrome supports several different process models, apparently, but as Spectre/Meltdown (as well as future renderer and UXSS bugs) mitigation it now by default runs a minimum of one process per site/origin (site isolation). See https://www.chromium.org/developers/design-documents/process... and https://www.chromium.org/Home/chromium-security/site-isolati...
To be fair it does seem like a stupid mistake of the system, not something inherently bad about it
I’m from Milan and it’s totally surreal to read of these places I know so well being shut down and paralysed.
I read the article and largely agree with aaron965 on this.

There's a number of problems with saying "every responsible human being should be interested in knowing ...":

1) does knowing make you legally or criminally responsible for spreading the virus, as in the case of early AIDS patients?

2) Being exposed doesn't mean you'll get sick. So what to do next with the info you met somebody who is in the database?

3) In most Western countries, citizens can afford health care. However, in the USA and other developing nations, affording a hospital is not an option. So what's the point?

The article presents an interesting idea, but separating policy and technology concerns when it comes to healthcare is really not a great idea.

For now I think the traditional methods of dealing with seasonal flu make the most sense: offer information in the press and make affordable shots available.

How true is that for other countries' aircrafts? I'm somewhat skeptical of your claim to be honest, seems like a easy decision to not buy at all- there is no knowing ehat teams would form in the kind of war that would need these aircrafts at full scale.
Revision history is essential for traceability in safety critical work. The entire history with name and timestamps can show both who introduced a problem, but also gives context for how a more subtle architectural issue got baked in slowly over time by multiple people. It can then be fixed, and possibly the process can be updated to help avoid such hard to spot issues in the future.

That was overturned upon appeal and then Microsoft settled to avoid any further legal troubles. I don't think you can claim that was a breach of antitrust law.
> I wonder of the same will be said for pandemics?

It does.

Hong Kong experienced SARS in 2003. The pandemics hit the city hardly [1], infected almost 2000, taking a hundred lives, of which several are medical practitioners.

This time Hong Kong citizens sounded alarm as early as mid-December. They advocated locking down the border from Mainlanders in mid January [2]. The dysfunctional Government was completely oblivious to the situation until at least mid Feb.
But the people with vivid memory of SARS took the situation seriously. Mask were used almost ubiquitously in late Jan. Hand sanitizers are equipped by everyone.

It is a stark contrast compared with expat or new mainland immigrants.

It may well be the reason. I don't know the parent commenter but speaking from my own experience I recently tried to migrate a legacy code base from svn to git and the common tools all failed for me. One of them ran for ~72 hours before falling over for "reasons".

That was only ~6 years of commit history too. I could imagine 30 years is a whole extra logistical challenge. Not to mention making sure the whole developer base is aware of the change, prepared for it and willing to either update documentation where it refers to revision numbers or write some instructions on how to find a new commit reference from an old revision number.

The tag model is also different between svn and git.

It's not out of ignorance that the switch can be difficult, we've had some projects on git for years and we're comfortable with it.

Just because you've switched easily from svn to git doesn't mean everyone has the same experience.

You can game the work task too right? Someone posts the question on glassdoor before you realize...

Here's the thing though. I don't want to work with an engineer who hasn't read anything technical in the last year. Don't care how good of a problem solver they are, if they don't teach themselves things they probably aren't very passionate about the profession.

`git bisect` to find when and how a bug was introduced, getting details when it’s time to merge multi-month merges, getting stats about previous projects.
Here's the right math afaik. Over 15% of infected people need a hospital bed with oxygen to survive (that's the important number, not just those who need ventilator). Doubling time is a week or less. Hospital stay is two weeks or more. Infections should slow down once half the population is infected. We can mostly ignore the time from infection to hospital, because it's a constant plus a spread that's shorter than hospital stay. So at peak load, 50% of the population have been infected and passed the initial period, 75% of those have passed the initial period within the last two weeks, and 15% of those need a hospital bed to survive. That's 5% of the population or more. Hospital beds are way fewer than that, so most of these people die.

The only hope is to slow it with non-medical measures. Check the progression dashboard for your country: https://coronavirus.arik.io/ You can see which countries are serious (most of Asia - graph looks linear) and which aren't (US and most of Europe - graph looks like a hockey stick).
The issue is not-so-slightly different.

The total number of places available in a given country in ICU's is (assuming a perfect world) the exact needed amount for "ordinary" cases + some slack, let's say 10%.

So you cannot count the total number of available beds as if they were free, as 90% (or change the percentage according to the specific country) are always, constantly, in use for patients affected by other - totally unrelated to Covid-19 - issues.

Part of these "ordinary" cases can be reduced (as an example by delaying a number of not-really-urgent surgery interventions) but this is also not without consequences.
Prices cycle up and down when you are that far in advance. Lately airlines are changing rates multiple times per day and using ML to maximize their profit. It's much harder to predict when to buy. Many articles about ideal days and months to purchase are becoming obsolete.
Without a timeframe this data is meaningless. 1 month, 6 months, 1 year, 5 years, 10 years??

The media is not very helpful here. I assume its meant seasonal, 2020 - but that's just a guess.

I've been on Keto before — eating whole foods is much simpler, there's no counting of carbs involved, no danger of developing a nutrient deficiency and no fearmongering ;-)

> "Keto says "you can't eat any of that junk". Just, flat out. No points, no "a little bit of ice cream", just, no. The easy calories are not an option."

This is also a recipe for getting an eating disorder. You can't stick with this mentality unless you end up thinking that carbs are poison, which is factually wrong and a very unhealthy mentality. And do you have the same mentality about fats? Those are "easy calories" too.

Sometimes it's OK to just have one cookie. If that doesn't work for you, fine, I've been there and I can understand wanting 100% compliance, but personally I feel much better since giving up on such a goal — because no, food is not poison, food is not alcohol, chronic overeating is the problem (aka energy poisoning) and chronic overeating can happen once you develop what they call "an unhealthy relationship with food".

I now naturally want whole foods, because I get to eat more volume and it keeps me full for longer. Once I got the taste of it, I don't need to fear food categories in order to stay on path.

> "For years there were stories of people eating below maintenance who aren't losing weight"

There's no such thing. People that eat below maintenance and not losing weight are either:

(1) underestimating their calories intake or

(2) have overestimated their maintenance requirements

If you're not losing weight, then by definition you're not eating below maintenance. And note that it is true that some medical conditions, like hypothyroidism, lead to a lowered metabolic rate (the thyroid is responsible for raising your body temperature for example), but in all cases we aren't talking about more than 200 - 300 kcal. So in order to lose weight, even people suffering from hypothyroidism can simply eat 2-300 kcal less — it's harder but it can be done. And if you claim a bigger penalty than that, you start breaking the laws of physics.

> "just recently science has learned that gut biomes can drop (increase?) their efficiency and result in a lower BMR than normal"

No, that did not happen. The research you're talking about was inconclusive and it was done IN MICE.

There are indications that the health of the microbiome is important, however the associations between the _human_ microbiome and obesity are weak and don't appear to be causal.

I.e. people that are obese tend to eat a less diverse diet (less whole plants). Such people also have less diversity in their microbiome. You cannot infer from that the microbiome is what caused their obesity, the huge confounder in such associations being the diet itself.
just an anecdote, but they're all over Portland. Just about every restaurant or coffee shop near any main urban thoroughfare has them. The shop owners will often refund the quarter for customers, but they do exist.

It's the private business owners (unethical..) way of dealing with a fairly huge homeless problem.

It's not just small places, either. A Target I happened upon had such coin devices on the bathroom door.

another anecdote : i've never witnessed as much (illegal) public urination in one spot. I watched a homeless man piss on a glass window with two indoor female onlookers at a Starbucks that was about 4 blocks from the convention center PyCon was being held at.

The absurdity of the act made me crack up, but I can't help but wonder, then and now, whether or not such absurd grotesque behavior is fueled partially by things like pay-bathrooms.
That always works like a charm!
The timing of this vulnerability release is hilarious. AMD had their financial analyst conference on Thursday afternoon. The stock rallied after market hours and ended positive on Friday while everything else tanked along with the US economy. That’s how good of a bet AMD is right now.

These news are Intel sponsored.
https://twitter.com/HardwareUnboxed/status/12360799707298652...

Also the release does not quality as a new vulnerability vector like Spectre, just a new attack against a previously mitigated vulnerability. It honestly looks to me like anattempt to stop the AMD momentum.

FD: The fastest processor I own is a 16 core Xeon, and is great. However, I have invested in AMD stock over the last year. I have a lot of respect for Intel engineering, but the AMD roadmap just looks stronger between now and 2022.
