> Thats not the right way of thinking about it. Sure, the first non-zero digit of any binary number is 1, but who is to say that the number has a bit that isn't 0? Couldn't the number be zero?

When I was taught scientific notation in middle school, high school, and at college, it was always explicitly stated that:

1. You can have only one digit before the decimal point.

2. That digit cannot be 0 (unless your number is 0, of course). So 0.3 * 10^5 is not scientific notation.

This is no different. The "twist" is that there is only one possible non-zero bit, whereas in decimal it could be [1-9].

I think this explanation is neat. However, the "usual" formulation is just scientific notation, with the optimization that one bit is redundant.

Personally, I prefer the alternative notation: M * 2^(exponent-precision+1), with M being a p-bit integer. It's easier to work with when you know that M is always an integer, and you don't need to deal with fractions in base 2. In fact, FP made a lot more sense when I took this formulation in decimal, and worked with that.

As a European, that isn't great. (options excepted). Usually I thought you get 14 weeks plus a month for every year of service, not a week.

You actually have to pay the full premium for healthcare. But still, assuming a months pay covers at least 3 months of Cobra coverage, that is 3 months PTO to get your head straight.
I think equating this with violence is superlative, but certainly has some equivalency to industrial sabotage.
There's no vaccine yet. Given how many people are asymptomatic, I expect the virus to create a new wave in a business as usual scenario. I think people will be quite cautious, particularly in international travel. Local bookings should probably be higher than usual, foreign visits much lower than normal, but it's mostly foreign visits which drives airbnb worldwide as far as I know.

Second I really wonder if things will open up as per usual. There's a lot of talk that we'll see things stay restrictive for the rest of the year. Many countries for example mandate face masks in public transport. Some countries mandate offices to fill to at most 50% capacity, mandating 6 feet of distance. There's many countries which expect that to be the norm once things like restaurants open again as well. Basically the current supermarket model: you can shop, but only 50% of the normal occupancy. We'll likely see this for busses, for stores, offices, museums, parks etc. I don't expect a massive short-term surge myself.

I think that unfortunately this heavily depended on your bank. Wells Fargo really dropped the ball, but Bank of America was one of the first banks to accept applications and therefore disburse money. We used a regional bank whom we had an existing relationship with and it went pretty smoothly, better than if we had tried with WF.
A 2020 Vision of Linear Algebra, Spring 2020
A short introduction to Linear Algebra by Gilbert Strang
Ironically, in the DoD contracting world there are roles like this; SETA (systems engineering and technical assurance) and SME (subject matter expert) contracting roles from disinterested third parties are usually a required function in DoD acquisition programs. These folks are basically paid skeptics of the work being done by the prime contractors, which is a good failsafe to build in for >$100MM tax-funded programs and for weapons and vehicles that can kill people. In this particular case, though, the hokum is coming internally from a government lab, and the work is early research, so it doesn't have to meet the same validation standards.
> medical staff are being furloughed

Some lazy Googling told me that mostly non medical hospital and healthcare workers are being laid off. And dentists and other medical practices are shedding medical staff. Dentists have been forced to close in California, except for emergency procedures. But doctor offices and practices are allowed to stay open, and people are free to go in for checkups and visits. Heck my local vet's office is open and I took my pet in for a non-emergency (i.e. concerning but not immediately life-threatening) checkup. People have been avoiding the doc's office for non-urgent stuff out of caution and fear, not because it's forbidden.

Disclosure: I work at Amazon, for AWS, as a VP / Distinguished Engineer.

Even though you work at AWS, there are ways to get familiar with how fulfillment centers work, and what the working conditions are like by doing the various jobs in a two day on-site program called C2FC. It's been nearly 9 years since I last did this, and I find myself wanting to do it again. It used to be compulsory training for all L7+ employees at the company, but this has been relaxed as we have grown larger, so some people aren't aware that the program exists. I believe that it is open to all full time employees, though they are currently not holding sessions (as you can imagine COVID-19 makes this impractical).

Getting connected with the right owners can sometimes be a challenge at a place like Amazon. As you're in an engineering role, the Principal Engineering Community is a resource can connect you to other engineers inside the company that are working, hands on, on challenging problems that include how we build safe working environments for FC associates. The SDEs in the operations organization are customer obsessed, and those customers include FC associates who use the tools and technology to perform their daily work. You can consider transferring to work directly on technology that FC associates use, and directly with the associates who use them as your customer.

Raising concerns internally to the right owner, in good faith, has always been welcome in my experience at Amazon. If you aren't directly in an organization that is working on solutions, progress might not be visible to you. There are challenges where we all are not satisfied with the speed in which we are able to address them. But that does not mean that there aren't coworkers working earnestly in doing so.

If you would like to reach directly out to me, you can via email or Chime. My login is "msw". I try to keep an open door policy, as much as my schedule allows, and practice discretion in how I try to address concerns. However, I cannot promise to keep every conversation strictly confidential, as I am obligated to report probable violations of the Amazon Code of Conduct and Ethics [1] in my position (including any discrimination, harassment, or retaliation of any reports of misconduct or concerns that are made in good faith by an employee).

This is something I'm actually working on at the moment (website rather than app). I agree that tech alone isn't going to solve this issue, but that's not the same as saying tech doesn't have a role or isn't a prerequisite
Sure, but did they ever sell in California? I specifically said that a company that is already here would have a hard time justifying pulling out. Especially since their HQ is here.
Its nice if you can avoid creating new objects, but in recent optimization I've seen no difference between reusing objects vs immutable objects. Removing unnecessary code is always nice though.
So more like cloud-based extortion?
I expect that would actually be too fine-grained for most users [...]

Even with that level of detail on the backend, there's no need to expose it all the user by default. That is, you could tell the user about group various related events together (eg. mouse, page load, etc) and power users could also drill-down if they like.
I imagine it's next to impossible for a rank-and-file to get access to sensitive business data like that. And anything from outside the org is anecdata or will be treated so by management.
Same in Israel, but it's mandatory to pay a months' wages for every year you worked at the company. The employer has to pay into a fund that the employee can cash out when they're let go.
I might be the only one but for such a simple website I found the menu confusing. When changing renderers, the order appears to change every time so I forgot which one I was previously looking at. Also, the Count is always reset back to 1000 so it's annoying to compare renderers at the highest count.

I don't see how you could do a comparison since neither of the company publish any metrics? They're not public and not required to publish any financial or operational information. Turns out it's not even possible to figure out how many employees they currently have. ^^

Just one tip. Don't do the mistake of taking Expedia in place of hotels.com. Expedia is a large conglomerate of many companies that is not representative of just that one. It's like confusing the mobile related business of Samsung versus Samsung as a whole.
Amazon pays their warehouse workers more than competitors. All the negative reporting about them seem to ignore this fact.
Ask HN: What tech should I use to built a CRUD API?
I build this kind of apps for work using Go but I don’t really enjoy the language and I‘d also like to use this project as a way to learn something new.
I’ve investigated a bit and there are some things I’ve found but I’m not quite sure.
1. There’s Ruby (with Rails). The consensus seems to be that it is nice to develop but very slow performance.
2. Elixir (with Phoenix). Seems like a functional Ruby on Rails with better performance, but I’m unsure about functional programming and also I feel like learning this skills won’t be of much use in the future.
3. Node. There are so many frameworks that I’m already confused and have not even started yet.

Ideally, the language and/or framework would have some job market.

Can you please shed some light on me?
There is, unfortunately, the risk of others doing the exactly the same thing subsequently, because they'll see this as a black swan event that will clear out the market of smaller overleveraged AirBnB "hosts", leaving them to purchase the properties in question. There are some big players, such as "The Key Collection", who are heavy users of AirBnB, with a large number of properties, as well as more legitimate properties like hotels, guesthouses, &c.

There are a few important things to keep in mind.

The Irish government has not been very good at enforcing the law around this kind of thing, and I see no reason why that should change, especially as the biggest party on the government side of the Dáil was the main party in the last government, and their records on housing (they're basically Tories) is notoriously bad. The other party in the proposed government is an ideologically similar party, and the one the caused our economy to implode due to property speculation in the 2000s.

The outlook is not positive.
Ask HN: Where are you hosting your in-person meetings and why?
There are more types of plants than just corn. Trees are much easier and cheaper to establish than solar for example.
The "correct" solution is that for every 40 hours of human work a company should be required to pay for a health plan and some number of hours of vacation and time off or get fined. And, if they subcontract, they are responsible for the subcontractor paying that or both get fined.

People with professional degrees and a spouse who pays their healthcare. No big deal. Certify it and document it. Life goes on.

Good for you. For us, it was announced as an optional WFH, entirely at the employee discretion (unless they are in a role that has hard requirements of being in the office, like hardware engineering), until October.

To me, that sounds like a perfect opportunity to work remote on a nice beach during the day, and enjoy my time during the evening in a new place, without having to take days off for that. I get concerns of some people like you, and I am not trying to diminish your choice to stay at home. But your take on this is not representative of what everyone else will be doing (and neither is mine, hence why I expect AirBnB to still have that 50% revenue drop), so I wouldn't discount my original point based on that.
sshfs (and samba for that matter, even more so) can cause odd kernel behavior and crashes, unfortunately. They're great when network is 100% perfect, if you never suspend laptops, etc. If any of those assumptions go away, you've got a mess.

Nice.

I don't agree that this is a negative long-term consequence, but I see your larger point. Do you think the government is capable of correcting problems such as these without negative consequences?

> Voluntary choices don't imply preferrable or desirable choices.

But what other metric is there? You intend for the government to regulate into existence preferable or desirable for everyone?

> Humans aren't perfect economic machines,

Should the government force people to do what's best for them against their will?

That means they still use the address bar though, doesn't it? Either to type the search term, or to go to Google.com.
Solid advice. Many of the tools listed that are "free" simply have a free tier. The free option could very be the wrong option, and it may make more sense to pay a little bit to start off with the right tools.

Standards always generate debate. They almost always can be improved. But hey, they are usually good enough for most use-cases. The price we end up paying, though, many times without noticing, is that layer over layer of "good enough" ends up making life much harder than it needs to be. But we only change when a single layer is clearly identified as painful enough. The article is technically very interesting, but for the general discussion my main question is: what mechanisms do we have to effectively move forward with standards? Are standards committees (good) enough (when they exist)? Are we moving at the right pace?
Most of the important topics were covered years ago. Encyclopedias are not high-maintenance; the maintenance team for Britannica wasn't all that big.

I had a similar experience also at age 11 - I was learning C++ to solve my math homework problems. I heard about Python, tried it out, and went on IRC to ask how I could write "goto" statements in Python. I couldn't believe it when people told me they weren't necessary, and linked "Go To Considered Harmful"!

The exponent is 8 bits. That translates to 0 through 255. This means your "window" begins from [1,2], [2,4], etc.

That sucks. It means I cannot represent any number between 0 and 1.

Ideally, we want the exponent to be somewhat symmetric, which in this case means going from -127 to 127. To translate 0 to 255 to that interval, you subtract 127. You are simply shifting your exponent so that the allowed values for your exponent is symmetric about 0.

Now your window starts with [2^-127, 2^-126] and so on.

(I may have an off by one error here).
Much of the deployment of OAuth2 was a shitshow, because early on, there was a huge debate about OAuth1 vs OAuth2, and the concepts and terminology used in the OAuth2 spec exceeded the mental load of people who were simply looking for a quickstart to some API. Docs by various providers either adopted the OAuth2 terminology wholesale without sufficiently explaining the new concepts and the best practices, or they simplified the client registration to just a few fields and offered no guidance as to make use of them in your app.

The spec has been clear from the start that there are clients that can protect their secrets, and ones that can't [1]. Here's a choice quote: "A native application is a public client installed and executed on the device used by the resource owner. Protocol data and credentials are accessible to the resource owner. It is assumed that any client authentication credentials included in the application can be extracted." Unfortunately, much of the rest of the spec is a bit like a playing puzzle, where reading it in one sitting doesn't actually build your understanding, and you have to constantly cross-reference various sections to construct a complete picture of the process the spec is trying to set.

It look a long time for people's familiarity with the spec to grow, and for providers and clients to improve in quality and adherence to the ideas and text of the spec.

Totally agree, just wanted to point out that I've been running Arch on multiple desktops & laptops for years and never had to compile a driver before. Maybe that's a thing for niche hardware but pretty much everything just works, even on Arch.
You want to do the right thing, and that’s commendable, but you have to recognize that you may not have enough information, particularly as a virtual outsider, to force your own management decisions in this case. It may seem like Amazon is being greedy here, but they creating many jobs that otherwise wouldn’t exist for people who live on the margins of the economy. And by driving down costs, they’re driving down prices. That may not matter too much for you, but it matters a lot to most people.

Look, there could be adverse effect from what you’re trying to do. The going narrative is that Amazon is evil and is just abusing it’s workforce. I doubt work is great in a FC, but there are plenty of worse jobs out there that don’t get as much attention. And just imagine what it’s like working in most other parts in the work. For many people around there world, a FC job would be a dream.
It's not "in my own way", it's some kind of physical disorder where I legitimately get a sense of panic if things aren't responsive for more than a couple hundred milliseconds when they should be, a great example would be when explorer.exe jams up in Windows and everything severely stutters.

I wish I didn't deal with this but a little sensitivity towards users like me would be nice instead of ironically writing us off as close-minded. I have diagnosed OCD and it's just a facet of that. It can be quite frustrating at times when I'm trying to use an interface and, say, intrusive thoughts lead me to repeating body movements like clicking or picking up and dropping my mouse and next thing I know my browser is closed and I've opened up another program without even realizing. Like it happens all day while I'm working and the more invisible my interface the better. It's not easy to overcome these physical impulses and reactions. I still deal with vocal tics and stuff like that.

One hilarious part of all this is that I'm not strongly contemplating getting a mortgage and buying a place _purely_ on the basis that between taxes and repayments, it would cost me 2/3 the amount I currently pay in rent.
I've seen both and as an employee the semi-monthly is the best - it's about biweekly but you don't have to wonder why some months you only see 2 paycheck vs. 3. Predictable is really good.

From a company standpoint, not having to accrue the liability on the ledger simplifies the accounting auditability & ability to close your books monthly.
It's not just popularity; it's an adaptable enough design to work in the range from 150 baud acoustic modem links to 40 Gbit fiber optics. Not many designs can withstand that, no matter how hard people try.
What's interesting is that, humans get to control computers, but computers don't get to control humans. At least computers are not originating thoughts on controlling humans yet. So technically we could get in by asking a computer to do it, but not the other way around yet.

> Sure, but did they ever sell in California?

Yes. Barrett (for one example) entirely pulled out of the state including sales to police. They left 10s of millions in sales.

For automotive performance, no one as large but I can tell you hundreds of millions don’t go to California because it isn’t worth the ridiculous rules CARB put in place and how one regulator will approve and the next will deny.

going public at any point after nov '19 probably would have been a disaster for most employees due to lockup period. Let's say I have $1M of RSUs at IPO – fed+state gov wants 450-500k for taxes total. When I went through Uber IPO they only withheld ~30%, which leads to a $200k tax bill at the end of the year in this scenario. If stock declines 75% due to COVID before I can sell at expiration of lockup period, I'm left with $175k ($700k post-withholding * 25%) and $200k tax bill. Not sure about you but I'd prefer the non-IPO scenario.
