The laws of physics are time-symmetrical. This is true for both classical dynamics and quantum mechanics.

Various attempts have been made over the decades to try to come up with a deeper understanding. Examples include String Theory, Loop quantum gravity, and computational models such as those espoused by Stephen Wolfram.

What they all seem to lack however is a recognition of the intrinsic reversibility of the universe we live in.

In my opinion, the most promising research in this realm is actually around Quantum computation. By necessity, it accepts the reversibility at the heart of things, otherwise you couldn't have the sorts of logic gates you need to do Quantum computation.

By way of an entrance into this rabbit hole, look up the Ffredkin gate.
We use images/diagrams/LaTex/etc to communicate a number of tasks that are inherently visual, not to mention needing somewhere on the cloud to access it centrally.

As a casual org-mode user, I fail to see how org-mode is really relevant for a team-centric tool.
It’s a study with a fairly high number of participants and it has not been conducted by the controversial author of the flawed first study.
If they're unemployed now, but made above a certain amount of money in 2019, they may have actually received nothing.

Also, if they're unemployed because of this and just received $2900, the wise move would be to save that money for essentials, not new subscriptions.
Loan companies only give you access to cars that have a reliable resale value. Since Americans basically buy nothing but pickup trucks or SUVs you can only get loans for SUVs and trucks.
Maybe the travel, restaurant etc industries have stopped paying for clicks so Google gets less cash? My work cut down on PPC by a lot and we spent a lot of money on it.

3. Traffic is at record low levels.

My city isn't at all bike friendly, but at the current traffic levels I'd feel safe enough to take a ride - the bikes themselves are just so absurdly marked up that I can't justify the expense, so I'm running instead.
Show me a death certificate with the cause of death saying "Trump failure".
I have stopped buying WDS and Seagate (their 3tb drives failed sequentially in my zraid in 4 months and I just barely replaced them with new). And I am not buying even brands that were merged with them (here is picture how hdd brands "consolidated" https://www.mydatarecoverylab.com/wp-content/uploads/2018/07...). Those companiea must be punished (by not buying their products) for all the mischief they have done to our data for the sake of maximising revenue, they need to be aware it will hurt their bussiness.

Now I am having 3xToshiba drives and one Hitachi and for now I am happy.
My experience with Spacemacs was the complete opposite. There's a ton of inconsistency with the quality of the provided layers which is why YMMV when using it. The C++ layers up till last year was an utter disaster and I don't know if it's been fixed since.

The WORST thing about spacemacs though is their absolutely broken release process. The master branch rarely upgrades with fixes applied to the develop branch, and the tacit recommendation is just to run "on the bleeding edge." I have no idea why spacemacs users tolerate this, but my productivity has since improved after ditching it.
That or waste a day or two of your weekend on some trivial app to be nitpicked on some nonsense not in the spec.

I had a go at our manager recently after letting two people do our tech test then say they were too inexperienced. We could have worked that out before wasting their time.
Google AdSense: “we're going to optimize your ad settings for you”
> This needs a better source.

There won't be any better source. China will never publish these measures as laws or regulations, not in clear text nor formally acknowledge such "ban"h exists. It's an obscure code of conduct to extort companies in private sectors for "bad behaviour".

And yes it will be arbitrary enforced, the "ban" will differ from time to time and varies between provinces.
I've worked with Python professionally for 3-5 years, but only type-hinted Python for ~5 months. This is coming from someone who prefers Java, but I don't like Python type hints because they were bolted onto the language worse than classes, type hierarchies aren't mature, and if I wanted types, I'd be using Java. That said, you do need strong typing for a project once it hits a certain line count or developer count.
This advice is fine for the first year or so, but afterwards I would start trying out various packages and customizations. There are packages that can make your experience much better (projectile, swiper, ace-window, ace-jump, move-border, eyebrowse, winner, color-identifier-mode, off the top of my init.el).

And, of course, if you do any programming at all, you should install magit immediately. It is the best git experience anywhere, on any platform, period. It is an unbelievable productivity booster, and people who haven't used it do not even appreciate what it can do (ever wanted to quickly apply a single diff from one of your stashes to your current code tree? it's two keystrokes).

Approach emacs like you would a musical instrument: you are not expected to play the piano on your first day, and the first year will require some patience and training, but eventually you'll start playing those sonatas.

>You simply can't replace great optics with software (at least, not yet).

And even if you could, applying the same software to the output of big high-quality lenses would likely yield better outcomes :)
I think it's a bit oxymoronic to have a lingua franca that's also the target of unfair discrimination. Of course you can have elitism, but in the end most people have to trade with the common coin.
There are languages though like eg: Groovy where gradual typing is more designed in. It's unfortunate to me that Python has cultivated this attititude because it's like local maxima that prevents the mainstream getting to soemthing better. Python is the new perl / PHP etc.
The Proper Privacy Regulations TeleHealth Needs
Ask HN: How am I still able to order new IPv4 addresses despite run out?
I have heard for years now that IPv4 address exhaustion is a huge problem. Lots of warning have been issued before it did ran out, and now that is has, nothing seems to have changed from a end-user perspective. I just purchased a new server at OVH and it came with an unused IPv4 address. I am still using IPv4 in my everyday website developer life.

I know that ISP have pools of unused addresses and that they recycle old ones, but it seems to me that IP demand should be exponential, but yet it looks like they still have plenty.

So is this a "Year 2000 problem" type situation, where thanks to warnings, people worked hard to increase somehow IPv4 lifespan so it's not really a problem anymore? Or is it still a big upcoming problem, and I won't be able to order in the future new servers with new IPv4 addresses like I just did? And when will that situation happen approx.? Thanks
Yeah, and I had 3d shutter glasses that worked great with the trinitron... In 2000 or so. Nvidia 3d Vision came along later but now sadly those product lines are abandoned, I guess due to VR which is just not what I want at all
The only internal reference I had was a distant acquaintance who - as they said themselves - just submitted one that basically read "don't know them much but they don't seem to be a jerk".

So you can absolutely get hired in engineering without internal references. (I'm also on a hiring committee myself.)
Send a PR to fix that, the devs will probably appreciate the help.

You’re not being too demanding. You have established a set of expectations about interactivity and UI/UX affordances that iOS might not provide.

My opinion: With any phone, you are going to spend most of your time in a small set of apps. As long as the OS enables those apps to perform smoothly without being intrusive, you should be good to go. There are certain platform differences that can seem like paper cuts when making a switch -> share screen, default app settings, where settings are housed (centralized in the Settings app or hamburger menu in each app), default permissions, text manipulation, and the Home Screen. There is nothing like using the device to overcome the pain of these changes. also, the good apps out there have homogenized the platforms to some extent.

I’m speaking from experience. As someone who has had iPhones since the 1st OG iPhone, I used an android device for work email for almost a year. It wasn’t easy; there were some annoyances when I switched from work to personal, regardless of direction, but I found a way to ease the cognitive load: I used 3rd party apps for most of my tasks. For example, Chrome or Firefox, Overcast for Podcasts, Pandora or Spotify, Outlook for Email, Kindle for books, etc. The good app developers do a fantastic job of smoothing over the differences between Android and iOS.

Edit: Fixed a typo
Can’t get over the fact that even food banks are apparently drive-through operations in the US, in what appears to be a suburban wasteland...

And considering that the increase in demand here is exclusively people who had a job until the bottom fell out on the economy, shouldn’t the whole rationale for requiring people to waste time and go through this exercise of very visible shaming be re-evaluated?

As far as
I understand it, it was commonly believed that poor people aren’t capable of handling money and therefore should only get food, not money. That idea was never a good fit with changing unemployment numbers, and these days it’s plainly visible that all these people didn’t suddenly become drug-addicts incapable of holding down a job. So why continue humiliating them?
I actually found it a bit rough at first but it seems OK now. That took maybe four weeks. But perhaps I was motivated to persevere because many regular deodorants give me a painful rash.

It might not be quite as effective as commercially sold deodorants. Obviously I'm only one data point but if I use it once a day I'm odor free for at least 24 hours.
One recent report: Two hospitals in NYC did universal screening of 215 pregnant women admitted for delivery between March 22 and April 4th. 15.4% tested positive. Most of those testing positive (87.9%) had no symptoms at the time they were admitted.

Sony has been the only company doing them, but the Z3 Compact was the last great one. I have an X Compact now and it's not as good. I've never had a big phone. One of the main reasons for getting a smartphone for me was the favourable size (easier to fit in pocket). The huge ones have no advantage. I use my PC for a big screen.
Still no proper Firefox with proper browser extensions/add-ons, still no interest in iOS devices.
So years ago this came up with Eric Schmidt, who was CEO of Google through the GFC. After 2007, Google had selective layoffs (probably not in engineering) and slowed hiring. They also paused construction projects in Mountain View and probably elsewhere.

Eric said when asked about it that it was a mistake. He said that if Google was healthy there was no need to have a kneejerk reaction to the slowdown. And this caused significant growing pains later.

Is the situation the same now? I'm not so sure. I think this economic shock is potentially far more serious and could last much longer. But also, I don't think Google really knows what Google is anymore. We're long passed the mission statement of making the world's information accessible and useful. And certainly my impression from working there (now >3 years ago) was that even then there were a ton of teams and orgs that didn't really have a reason to exist.

Have people sitting around and they will find things that "need" doing. I saw many a project that was simply rewriting something where I at least had questions as to the real need for that. The bureaucracy is expanding to meet the needs of the expanding bureaucracy as they say.

And there was (and I imagine still is) too many layers of middle management. The ideal is (IMHO) CEO -> SVP (PA level) -> VP -> Eng Director -> Manager (of managers) -> Manager (of ICs) -> IC. That's 7 levels. I don't know what Google's mean org depth is in engineering but my guess is it's closer to 11, maybe even 12.

In fact this would be a good metric:

Management overhead = Mean org depth / log(# of employees)

where

Mean org depth = Mean of how many layers each IC has above them
The NE555-timer is quite a cool little thing.

More common operational amplifiers are also worth looking into (TL072 is one of my favorites).

Lastly, the 7400-series logic chips are SO interesting. If you need the programmer's version of a jigsaw puzzle, try to build somewhat advanced designs using those. It's very fun and a good learning experience (although hard!).

Some people can learn to do more than one thing reasonably well and more easier than others. I won't be surprised if we see another headline in 5 years telling us that Mr Levy is a rocket scientist working for NASA, or he started a successful business or he is an acclaimed novelist.

Also, back in 2008, Google didn't hire/freezed its hiring, but Facebook and Amazon were still hiring like mad, and it worked well for them. They are used to ride out recessions.

Richi's Lab[1] also contains a large number of pictures and analysis of decapped ICs. He's also documented his decapping process[2] which uses an oven rather than the dangerous acids, making it more approachable.

It's all in German, but Google Translate does a good enough job that it's easy to follow.

He's got a very interesting comparison of STM32 originals and clones, as well as various voltage references, 555 timers etc.

A personal favorite is the LTZ1000[3]. The die is a piece of art.

In times of economic depression is best to build and acquire, if you have the money to do it.

Acquire skilled people (it would be much harder to do it after crisis), buy land, buy companies, build buildings, build tech.
8051 ( https://en.wikipedia.org/wiki/Intel_MCS-51 ).

Still probably the most common microcontroller in existence, just because it's embedded in so many other ICs. 40 years old this year.
I think it's also important to look at scale - in 2007/2008, Google had ~25.000 employees. Now it has over 100.000. If I'm looking at the graph correctly, Google hired 20.000+ of those in last year or two. The size of whole company in 2007!

That's a whole different ballpark than what hiring was in 2008. A slowdown in this scale can easily mean "just" hiring more people than anyone else.
Yes. If you search at Bind, seems like some in marketing too.
Learning GNU Emacs, 3rd Edition
http://shop.oreilly.com/product/9780596006488.do

I've been using Emacs for ~5 years now, and I switched from Sublime Text. I used Vim here and there but I wasn't a huge fan, and I always heard that Emacs is _the editor_ that can solve anything. Org mode is what got me really interested so I read through that book and switched to Emacs fully after a couple of weeks of light usage and reading.

Now I only use Emacs, and I've never been happier programming. It's truly a remarkable piece of software.

Edit: just want to say that you should use vanilla emacs and try not to install any plugins at first. Resist the temptation to go willy-nilly on some awesome-xyz list.
From what I have heard this is a problem with OLED panels.
Your sole view is not the final authority on what's right for a company. Google has done many things right while growing to this size. It still retains top talent something that other big companies struggle with. And yes I'll just wait for HNers who are disgruntled about being rejected downvote me. But the truth is 99% of the people will take a job at Google in a jiffy. I'm also proud of the response and employee support amidst Covid-19. Look at Amazon on the other hand. Google is going to be just fine.
One color I would add - hearing the tax season deadline moving to July drastically reduced the ad spend from tax filing software services companies. Of course, ad spend is also just down overall.

Their productivity is directly related the to vast ecosystem of packages available. Those packages were written and maintained by the community. They are rebutting the assertion that this community is bad. It can't be that bad if they're helping millions of developers solve real problems around the world.

That’s how I feel. Isn’t it just the darndest coincidence that the worldwide deadly pandemic just happened to originate in the backyard of the only BL-4 research center in China.

It also interesting to observe the level of coverup here. That page about the visit was scrubbed, doctors silenced, etc.

How many vendors at the wet market, the alleged source of the virus, even sold bats or made bat soup and such? How does it compare with other wet market around the country or the world?
