Try counting number of DNS queries for all lookups every day. The software I wrote for myself does this and I can attest that sites using AWS nameservers in almost all cases require more queries than others, including those using similar managed DNS services. The number, which does not include queries to the root can be quite high, e.g., eight. No matter how fast the response times, that delay adds up.

root.zone data is reasonably static. Having a local copy of this data, resolution can be done in two queries: 1. tld ns 2. auth ns, which is the case for many, many www domainnames (the majority, perhaps), or even one query (I think some .mil domains used to be a well-known example). As a user, I view every added query as an additional cost.

It is possible to minimize queries via other means that are under user control and do not rely on third parties.

Running a root locally. Custom stub resolvers with tld ns IPs compiled in. Storing RRs for common nameservers in local zone. Storing DNS data in bulk for important sites that will be revisited, copying to HOSTS and updating the data periodically. I have been using techniques like these for many years. And, it is getting easier every year as more bulk DNS data is available, e.g., internet scans of DNS, TCP DNS services that accept pipelined queries, etc. (If I am not mistaken, the author of the "qname minimisation" draft also was the one with the "DNS looking glass" idea.)

https://tools.ietf.org/html/draft-ietf-dnsop-qname-minimisat...

Despite usual mailing list/forum comment/blog memes and mantras, if one surveys all websites (not just popular ones), DNS data is mostly static. That provides great opportunities for speedups by avoiding querying ICANN DNS for the same data 24/7/365. Cue Schopenhauer quote about truth. Someday maybe we will see an internet draft about "DNS minimization" for users.

Did AWS forums start requiring an account for read access?
Along the lines of this. Anyone in the industry, why do they not cross reference the street addresses of their current subscribers and reduce the promotional mailing list or mail relevant promotions? Maybe it seems cheaper to do it this way, but it's actually quite antagonistic to current customers.

Why would they not maintain a clean marketing list!?
My remark wasn't about commentators, but about those who oppose NN in general without any valid arguments. And I'm not afraid of criticizing that, instead of whitewashing as just another opinion.

An RTG uses the Seebeck effect, which gets you microvolts per degree kelvin. A Stirling engine can theoretically extract many times more energy from the same temperature differential, but with a larger complexity.

Long story short: iTunes will always be launched when a media key is pressed unless it is explicitly disabled.

I take it that they're not using MediaPlayer.framework (https://developer.apple.com/documentation/mediaplayer), which was introduced in 10.12.1, that solves this exact problem? I would suggest against installing this until this is implemented.

The funny thing is that a pleasant, over-promising person who pretends to know more than they actually do would be fast tracked for management at a lot of companies.
This is great timing as I've been rolling this around in my head for about 6 months now, thanks for posting it. I have yet to find a good exit plan.

My issue isn't really the work itself, it is the risk that comes with stepping out on your own when you have a family to support. I have seen firsthand what a failed start-up/small company can do to a family (twice actually) and it scares the shit out of me. That's one of the reasons I am so hesitant to live off of savings while the work pipeline builds.

On top of that, my family and I have grown accustomed to our current income level which I don't think I could keep up as a consultant/freelancer/etc, at least for the first year or so.

For me the question is: is my full blown happiness, with my career, worth potentially risking our future and current lifestyle? It is a really hard question to answer...
I haven't used this, but if you're considering this I would highly recommend taking a look at https://flynn.io.
No. We’ve mostly hired not OPT/H1B. But I’m generally interested in hiring the best candidate regardless of nationality.

My concern is spending the resources on a good OPT candidate only to find that I can’t hire them long term. Previously I didn’t have that concern. Now I do. So I’m wondering if others share that concern.

> What's the advantage over direct thermoelectric conversion?

Stirling engines can approach 50% efficiency [1], whereas thermocouples are usually less than 10% [2].

H1B candidate here. I was awarded my first term as a developer, but I am required to provide more evidence on my second run because they didn't believe that I was qualified as a web developer. I mainly work with newer technologies such as React, Elm, NodeJs, but they're not 'buying my worth'. I have a deadline to fulfill or I am kicked out even though I'm very much qualified.
From what I've read in the past, it's not the crop is very water intensive, but rather the technique used to irrigate are water intensive. Take in comparison, "flood irrigation" vs techniques developed to irrigate in desert condition using "drip irrigation".
Why do recent macs throttle based on battery? I don't think my iMac has a battery to replace?
I admit some envy of people who find their passion early and make the most of every year of their life leading up to a career, but if he's so smart and driven, why is he working at some "boring tech" company as a cog under some layer management? Why doesn't he consult solo and reap the fruit of his precociousness?
(edit: shortened dramatically. apologies, earlier wasn't all that useful.)

With the exception of cross-repo code review (I hadn't thought of that one - would be useful for multi-repo too, but I've honestly never seen a multi-repo tool for this, thanks!), this is all just the benefits of standardization, plus a massive injection of tooling enabled by the standards.

Standardization of projects brings huge benefits when it's done right, absolutely agreed. But that's entirely orthogonal to mono vs multi.
I don't know if it's my age/class/nationality/background or what, but there is no way in hell I would participate in any serious discussion on a platform like facebook, both because they're using that data, and because it's notionally attached to my identity.

Indeed, the main reason to have an account there now is to avoid the "you don't have a facebook account" judgement.

The thought people would put themselves out there like that strikes me as being incredibly privaledged or incredibly naive...
Amazon is to blame. They are probably offering rates that can only be met with sweatshop conditions. I see that at my company. Contractors are used to wash the the company free from any responsibility but they know exactly what's going on.

Right. We don't actually know whether this Haskell code is less efficient - that depends entirely on the implementation.
This is similar to the "Stirling radioisotope generator" [1] but it is an actual nuclear reactor (albeit a small one). Both systems are a response to the same fundamental problem, the dwindling supply of Plutonium-238 [2]. The Stirling radioisotope generator uses Pu-238 more efficiently than thermoelectric RTGs, and the nuclear reactor from the article dispenses with Pu-238 altogether.

It is accurate in my experience. I’ve lived in Japan for years and the only crime that is even remotely relevant to my daily experience is fraudsters taking advantage of seniors in my family. No petty theft. No violence. No threats. No assault. None.

Having said that, I don’t gamble or visit host clubs and avoid making enemies in general.

I often see your response about manipulation of statistics, but it is simply indisputable that crime is negligible in Japan compared to Anywhere, USA.
The gameplay is smooth and everything is nicely done. Good job!
Thank you for your candid response.

Would you be able to answer how many packages the average driver delivers on a route and what happens if a package is stolen i.e who is liable?

Which is exactly why it is subsidized. The goal is not to save companies money, but to save natural resources. Now, I agree it is debatable whether recycling achieves those goals, but a free-market approach, as introduced in the video, will only be more harmful.
The rich, who benefit from tax breaks, spend copiously on issues that influence the poorest’ votes. Abortion, religion, military, immigration, homophobia.

One Second iOS Data Recovery Software
This is a very cool technology, but frankly I have a hard time imagining that it will see much use. NASA sees public protests and scare mongering whenever it tries to fly an RTG, which is based in the radioactive decay of (usually) plutonium, and does not use a nuclear chain reaction. They did fly one on Mars Science Lab, because it was the only way to get enough power for the rover. But it takes a PR hit every time it does so. RTGs are therefore only used when no other technology will work.

It think it's likely that the public relations nightmare NASA would have to go through to fly an actual reactor will be through the roof.
Anyone know the approximate size of that thing? Hard to tell from the picture.
What the market is quoted at , is the latest buy or sell order.

The price you can buy at is the ask, the price you can sell at is the bid.
Please add pre-requisites as well to the model. For the vectors > linear algebra example: someone may need to re-learn a few techniques before diving in.

Huh, interesting device: https://en.wikipedia.org/wiki/Thermoacoustic_heat_engine

Is this actually a thermo-acoustic engine, or some other kind of sterling engine? Or are they equivalent? The article doesn't seem to mention "acoustic" (or an equivalent).
Actually, when I mentioned thermoelectric conversion I wasn't referring to an RTG (which is just nuclear decay) but rather to the true nuclear reactors that the Soviets put in space:

https://en.wikipedia.org/wiki/Romashka_reactor
https://en.wikipedia.org/wiki/TOPAZ_nuclear_reactor

They used thermoelectric conversion rather than a Sterling engine with moving parts (although I guess TOPAZ is technically "thermionc coversion").

NP-Complete problems can't be solved in polynomial time, but they can still be solved algorithmically, and the solution to an instance of a problem is perfectly well-defined.

Cool, thanks! It's really surprising to me that inserting a mechanical intermediary has such a large efficiency advantage.
Some friends and I used to hold a hybrid drinking/Project Euler contest. You would have hated our solutions. I remember winning on the back of nine nested for-loops and, on a separate occasion, doing a primality check using a literal array containing the first 80,000 primes.

That's what happens when time-to-solution is what you optimize for. I'm sure it's familiar to startup programmers :).
His point is correct. There are usually efficient and inefficient ways to attack each problem. It's better to solve the math problem first, before the coding problem.

Do you agree with any form of wealth redistribution? If you don't, I have nothing more to say. If you do, I would have to ask to what extent, and how do you arrive at this amount if poverty plays no part in your estimation?
My reason to use Facebook is to communicate with local businesses. They are not responsive on emails and calling them seem to much a hassle.

I use it for purely 'commercial' purpose and not remotely close of gaining information about what's going on on the world.

One other reason for me just 'having' it oppose to using it, it I just moved into a new city. It's, I think, a good way to have them added on the platform to get to know them.

I agree with you letting old buddies let go. I see, only communication worth keeping is via instant messaging, such as Telegram & Whatsapp. A good way to talk and let me know what's on with their life instead of having a constant feed. It remove the surprise factor along with things to talk about during instant messaging.
Hard to tell what the weight is, of course. Judging from the size of other objects in the picture (the lift point and the connectors) it's very roughly around four cubic feet. Which is actually pretty awesome; the equivalent solar panels would be significantly larger.
Has anyone studied these protesters? My off-the-cuff sense is they’re mostly older environmentalists.
Completely agree. Associating my actual views with my real identity makes me uncomfortable as well - not so much concerned about what Facebook would do with that data, more concerned with the fact that it will cause people I know or have a strong chance of meeting to dislike/hate me for a reason that I'd rather not give them.

Also, having a "debate" over FB sounds only moderately more pleasant than having a debate in the comments of a Youtube video.
Heh, this is a fairly easy mistake to make when implementing a DNS server. I’m the person that had to fix this very same bug (and possibly introduced it) for a certain class of domains in the Cloudflare DNS server. “Empty non-terminal” still has an emotional reaction attached to it. :)

Also, pretending all NXDOMAINs are actually empty non-terminals is a backwards compatible hack to compress DNSSEC responses https://tools.ietf.org/html/draft-valsorda-dnsop-black-lies-...
Right, that is what I was trying to say (and maybe did poorly). A plumber bids his own contract. These deliveries are bid and structured by someone else. It should be more like how most mechanics work (especially at a dealership). There is a book that says that job X should normally take Y hours to complete. The mechanics know their rate of payment per hour. The way you really make money is by being better than Y hours. Yes, you can still screw up and take 2Y but there is a floor that is "fair" and you don't have to be worried about people bidding Y / 2 and a race to the bottom.

Exactly on point. Overindexing on the futility of the future while simultaneously minimizing the plausibility of positive outcomes.

I have these same thoughts, and these same problems. The OP's post has left my mouth many times. Strong odds it's depression.

There was a time when you could give a christmas bonus to the mail man. I wish that the delivery men were more consistent, I would love to be able to give them a cash gift for all the work they do for me and my family on a regular basis.

Unfortunately it seems like during the holidays the usual delivery guy isn't around and it's a chaotic mix of people.

While we are here, I hate that they are now making people deliver on Sundays. Every year I struggle more with the morality of the package economy.

DAOstack – The Operating System for DAOs [pdf]
I've noticed this sort of thing a lot in the job market: performance or pay are directly tied to metrics resulting in employees being incentivized into odd behaviors (breaking the law, sabotaging coworkers, skipping breaks/lunch, stagtegically cancelling or avoiding work, etc). This type of management through metrics goes hand in hand with the gig economy and also temp agency/contract work.
Well in TDD you tend to try to do that :)
After hearing about it for years, I decided to start working through Project Euler about two weeks ago. It really is much more about math than programming, although it's a lot of fun to take on the problems with a language that has tail call optimization because so many of the problems involve recurrence relations.

I like that the problems are constructed in a way that usually punishes you for trying to use brute force. Sometimes there's a problem that doesn't have a more elegant solution, though, as if to remind us that brute force often works remarkably well.

I'm certainly not suggesting all leaders should be lawyers, just that a fair number of the ones making laws should be. The US legal system is complex. Every time my very business-minded senator opens his mouth, there's a real good chance that he will say something dumb about the way the legal system works.

Also, I'm generally not looking for laws that are innovative. Companies are suppose to innovate and risk a lot to do so. But if a company goes bankrupt, it's rarely a big deal. Governments don't have that level of flexibility. They need good, stable policy, from people who are good at seeing both sides of whatever argument is in play. You know what kind of people are good at doing that? Lawyers.
