> Corey's business exists because prevailing engineering culture encourages pretty much the entire industry to consider optimization as an afterthought, not because engineers can't understand AWS pricing, or interpret a few bar charts in Cost Explorer, and in the face of a deadline, if it's not on the agile board everyone knows it doesn't exist.

Nobody is actively encouraging the entire industry to consider optimization as an afterthought. This makes zero sense. Why would an organization pay a business to reduce their AWS costs if it wasn't worth the cost to realize the savings? Cost optimization is an easy task, as you've stated - so the cost/value proposition of a business like The Duckbill Group must not be worth it according to your statement. Yet they exist and do, seemingly, well. Maybe... Just maybe, cost optimization in AWS is not easy, not straightforward, and designed to be painful enough to where smart engineers are incented to leverage Amazon's dark patterns of hiding costs at time of deployment.

You even state...

> 80% of what he does is easily discovered a few clicks away from the AWS home page.

So why is cost optimization a constant point of conversation with AWS if it's so easy? Why do outfits like Digital Ocean advertise on the notion of clear billing as a positive differentiator compared to AWS?

> Cloudflare have a solid sales pipeline, but they're a sitting duck if any of the big clouds ever decide to replicate the business model like-for-like.

Let's take a stroll back in time. Do you think that Amazon and AWS have always posted a profit? Go look, they've posted many quarterly losses to get where they're at. That's how it works as you build a business like that. To your point - AWS does compete directly with Cloudflare in certain products, yet here we are, Cloudflare and AWS both continue to grow (negative operating income / net income are not a direct correlation of company growth BTW). A mistake you've made is around brand and reputation. Nobody thinks of AWS as a security company. Customers continue to buy Palo Alto Networks, Fortinet, Zscaler and, yes, Cloudflare - even though AWS offers some overlapping portfolio. Why? AWS isn't viewed as a security portfolio. Cloudflare has brand reputation in security and content distribution. And it's a pivot that easily works with both their brand and reputation.

> Outside some sweet Javascript cold start hacks they basically have no moat, and there are far more situations that could send the company into desperate measures than otherwise.

This just screams of the competitive argument low-road. I don't have ties to Amazon or AWS. I'm not an employee. When I read statements like this it's affirmation that there's some agenda. I laughed out loud reading that as the closing argument, thanks for that.

I was more thinking along the lines of an insider close to the device :)
Whatever you buy, just simply never give it the wifi password and never attach it to an ethernet cable that will give it a DHCP lease. Once it's phoned home and filled itself with ads, your experience is ruined.

I have a mid 2017 Samsung 4k 70" that works great as a dumb screen. It's attached to a home theater PC through a receiver, PS4 pro and an Xbox.

People say, but the PS4 and Xbox have ads in their home screens? Yes, sometimes they do, but I trust Microsoft or Sony a thousand times more to keep their operating systems patched and up to date.
Sceptre 55". Getting one in a couple of weeks.
Yes. What's wrong with changing math notation? Why wouldn't you do it if you know that it would make it easier for others to approach? What's the rationale behind doing exactly nothing to make the notation more approachable for the masses?
"That other animals have more cone cells than humans, e.g. birds with four and shrimp with up to 16, and so probably see colors we can’t even conceive of which, yeah, that limitation of our minds is frustrating, but it also hints that there are huge unseen dark continents of qualia lurking out there which someday we might find a way to visit."

This is based on a misunderstanding regarding the rise of qualia. It is processing power and not sensor capacity or at least both together in some combination with processing power doing the heavy lift. Humans have less cones but several OOM more neurons to make sense of what we have. So no - the shrimp doesn't see in spectacular color.

> Every math paper is its own DSL in this context with its own small explanations for how it does things.

That's really the point though: not every piece of software defines it's own DSL, nor does it necessarily incorporate a DSL from some library or framework (which in turn may or may not borrow from other DSLs, etc.). It is also impossible to incorporate something from other software without actually referencing it explicitly.

Math, though, is more like prose in this respect – while any given novel probably has a lot of structure, terminology, and notation in common with other works in its genre, unless it is extremely derivative it almost certainly has a few quirks and innovations specific to the author or even unique to that particular work that you can absorb while reading or puzzle out due to context, as long as you accept that the context is quite a lot of other works in the genre (this is more true of some genres/subfields than others). Unlike novels, at least in math papers (but not necessarily books) you get explicit references to the other works that the author considered most relevant, but those references are not usually sufficient on their own, nor necessarily complete, and you have to do more spelunking or happen to have done it already.

Finally, like prose, with math you have to rely on other (subsequent) sources to point out deficiencies in the work, or figure them out on your own. Math papers, once published, don't usually get bug fixes and new releases, you're expected to be aware (from the context that has grown around the paper post-publication) what the problems are. Which means reading citations forward in time as well as backward for each referenced paper. The combinatorial explosion is ridiculous.

It would be great if there were something like tour guides published that just marked out the branching garden paths of concepts and notation borrowed and adapted between publications, but textbooks tend to focus on teaching one particular garden path.
It's not wall power consumption. It's wall minus idle. Package power consumption metrics are often unreliable. If you have another explanation for where that power went I'm all ears, but my experience tells me that the on-board power consumption meter is simply off.

Actually looking closer at the data, the reported package power is often even higher than wall minus idle, which means it's almost certainly inaccurate.
The Best Buy Insignia brand has some dumb models. (They all used to be, but now they have some "smart" models.) The Sceptre brand is similar. After that, you're into commercial displays, which are expensive but of good quality.

If you don't need a tuner or remote or built-in speakers, a monitor may also suit you.
That's what I suggested with

>> Scan the entire internet for domains pointing to s3-website, and check AWS API to see if it's available?

What I wonder is how do you scan all the DNS records with their subdomains? Unlike IPv4 address space, which is very decidedly finite and not-too-big, the space of all the subdomains is basically infinite.

Other than using AXFR (zone-transfer DNS request) which is usually restricted, you are searching an unbounded space.

I guess you don't need an AWS API calls since hitting a non-existing bucket with HTTP will let you know: http://something.that.does.not.exist.s3-website-eu-west-1.am...

IOW, how would you write such a bot? :D
No problem. I'll try to download a Valhalla JVM build and see how it fairs.

Virus evolution paper from August predicted the mutations of B.1.1.529
I've had an LG OLED (65" C9) for roughly 2 years, and its the best TV I've owned, hands down. It is amazing for movies and TV, because of its inky blacks. (unliked LED/LCD, the OLED pixels are actually turned off individually) which are just as good as a Plasma I owned 10 years ago. It also supports 4K/120Hz for gaming, and looks amazing with my XBox Series X.

The primary complaint I've seen for this TV is that its not bright enough compared to LED models, but I've not found it too dim, even in a room that gets lots of morning sun.

Another OLED concern is burn-in. After 2 years of 90% Netflix/YT and 10% gaming (mostly Forza Motorsports 7), I have not seen any signs of burn in. Apparently the built-in image shifter/orbiter works well.

EDIT: In terms of smart TV misfeatures-- the voice search requires a scary opt in that I've never done. Aside from that, I'm able to disable most tracking, and I've not seen any targeted ads.

The biggest issue I have with the TV is that the LG the "magic remote" is incredibly annoying as it pops a cursor onto the screen randomly when moved.
Inability of third party to capture value they create - an apartment complex in the middle of the forest is worthless.

It needs utilities, shopping centre, major metro line, highway, arts, jobs, good schools, and general 'nice area' vibes created by artists on the verge of bankruptcy. None of those things area created by the construction company.

In fact randomly building houses leads to congestion, lack of places in schools and other facilities, and miserable living conditions.

> With the Winter Olympics opening in Beijing in February, the IOC and corporate sponsors have multi-billion-dollar reasons to help China make the Peng Shuai story go away. Therein lies a bleak lesson. The WTA has been brave in challenging China, given that it has organised lucrative tournaments there. But as a women’s sports association, it depends on retaining the confidence of women players. Sometimes there are incentives larger than China’s market.

It's remarkable that the WTA has stood up for Peng Shuai. International corporations typically knuckle under to the CCP. See the IOC's response, and also Jamie Dimon recently backtracking on his mild joke.
There is no such thing as a "China Export" logo. The familiar CE logo is a voluntary mark and manufacturers determine whether the item qualifies to use it or not. There has never been an organization enforcing the use of this mark.
The whole point of the web is that it is dynamic. There is no guarantee that a search result that was on page 3 last week, to use your example, will be on page 3 today. Further, in many cases, bookmarking page 3 of a search result produces a null result when accessed, because the web site needs you to re-enter the original search term.

> Anyone should prefer lots of customers to a few key ones.

I think the caveat/variable is "all else being equal or close to equal."

If having 10 customers will net you $10 total per month, and having one large customer will net you $100 per month, it is really hard to justify going with the $10 customers. But if those 10 customers will net you $10 EACH per month, then the 10customers is a better situation.
Just don't connect it to network or wifi. I would hope sets don't lock you out from viewing content through HDMI while offline (but check reviews to be sure, I would not doubt there have been heated discussions about it in some TV product manager meetings).
It’s funny that the GOP have expressed admiration for how Chinas governed and it’s resultant economy. (Even though America has a bigger economy and is a Democracy)

Mathematicians do document and comment, that's what papers and textbooks are: commentary on the math. They don't throw out formulae and equations and call it a day. Attaching a full tutorial for every level of reader is tantamount to attaching Stroustrup's C++ books to every C++ program, or K&R to every C program. You wouldn't do that, you'd expect the reader to ask you for references or to seek them out themselves.
Washing machines were one of the first applications for microcontrollers.

If you have an electric motor that's supposed to speed up, slow down, reverse, spin fast etc., all on a schedule, it's a no-brainer (pun intended). It's usually the pump that fails, but the controller-cards often fail too. Pumps and controller cards are, of course, outrageously expensive.

These things are supposed to fail. Back in the day, they were much more reliable. I don't think it's "smart" tech that has made them less reliable; I think they've optimised their designs over the years, so that they nowadays fail just after the warranty ends.

So what I want is kitchen equipment that is designed to last. For example, I bet they could build a washing machine that works perfectly for 30 years, for under £1,000. If they wanted to. It might not have 24 different program settings, but I only ever use one setting.

Yeah, reliable equipment probably is a bit of a nerdy preoccupation; but you'd think at least someone would have a product to appeal to that niche. But nobody seems to want to compete on reliability. That makes me wonder if there is a cartel at work.

[Edit] I actually don't mean to include Bosch in my comments about manufacturers; Bosch equipment I've had has been more reliable than other brands. But they still fail and need repairs much too often.

I’ll hijack this thread and ask, is there any tv that has the ability to change the brightness with a single button press on the remote, or adapts automatically to ambient brightness? On my tv, I have to navigate into 3 menus that take 15 seconds to load. It takes forever. I’d love it if I could repurpose the channel rocker that’s never ever used into a brightness rocker.

Ask HN: How did front-end and back-end titles get introduced?
When and why did we start splitting software engineering into front-end and back-end?

Was there a time when one could have been just a software engineer building websites or did the specialization was there since the beginning of HTML and CGI servers?

From Google Trends [1], it looks like maybe we started using this term in 2010.

My personal recollection: Around 2006 we had new projects like Google Web Toolkit (GWT) and JQuery which enabled additional complexity in HTML/JS. In 2010, angular.js and backbone.js started and helped address a sentiment that JQuery was not good enough for large projects. It became hard for a software engineer to handle the new front-end frameworks while keeping up with the backend as well. So it would make sense to have the front-end engineer title introduced around this time. However, I don't recall if there were discussions or blog posts explicitly introducing it.

As a counterpoint to most comments here, I've been using Polypane for a couple years now and it's been an invaluable tool in my arsenal.

To me, the threshold of cringing is when web forms are laggy. This 50-billion-instructions-per-second box can be slower rendering an input form than a VT220 terminal from 1983. When the task of the machine is to, e.g. enter appointment booking information, and it handles the task worse than hardware from decades ago could in some cases, that's when we know we've lost the plot.
This is what I have. It has zero 'smart' features and you can buy smaller sizes like 32". The TV has average audio but with the price, it is cheap enough to afford a decent sound bar if that is a sticking point. I haven't bothered with that myself and it's been just fine.
This is one of the reasons why the hardcore retro gaming people are still paying big money for 32" Sony Trinitron analog CRT TVs and such. Ultra low latency from image source to display.

If you have a good condition Trinitron like display these days (Mitsubishi diamondtron, sony pvm, etc) it is presently appreciating in value every year.

I’ve used the exact same TV without ever connecting it to the net or using any of its smart features. It works perfectly well as a dumb TV.

The picture is consistently fantastic.

Tools for DIY Manicure at Home
1. First, use nail clippers to trim the nail curvature and dead skin. It is because when the nails are trimmed well, the nail polish will be applied symmetrically and look good.

2. Then, buff the nail surface with the nail plate and wash it well if you are afraid that the manicure is easy to fall off. Especially when you have an uneven nail surface, it must be smoothed out first, otherwise it will look pitted out.

3. Apply the base coat to ten fingernails and then shine the LED nail lamp for 30 seconds. If the nail polish is slow to dry, it may take a little longer. It mainly depends on what kind of nail polish or nail polish glue it is.

4. After drying the base gel, apply your favorite color of nail polish or manicure, and then shine the lamp. After it dries, apply it again, just like the lipstick, the color shades will be different. Usually, the method of applying three times and lighting three times will be more appropriate.

5. After the nail polish has dried, apply the top coat and then shine the light. The top coat will make your nail surface brighter and longer lasting. If you want to put on something like rhinestones, just put it on when the nail polish is slightly dry!

A voucher is not money. A voucher is a type of bond that may be used to purchase goods under certain conditions. One such condition could be that the voucher needs to be spent before a certain date. It's nothing new either. Vouchers have been around for ages. This is not what OP was talking about. THE OP WAS TALKING ABOUT A MYTHICAL CURRENCY THAT WAS SUPPOSEDLY PUT IN CIRCULATION IN CHINA AND THAT WAS PROGRAMMED TO EXPIRE AFTER A PERIOD OF TIME. THERE IS ZERO EVIDENCE THAT SUCH A CURRENCY WAS EVER PUT IN CIRCULATION IN CHINA OR ELSEWHERE. THEREFORE I WAS RIGHT TO POINT OUT IT WAS FAKE NEWS.
Part of the point of our bed time ritual is to look for and accumulate "gratefuls" throughout the day. In this way, I am training my pattern recognizing CPU to spot the positives rather than the negatives that it tends to focus on.
That's for Windows x64 (cdecl specifically), which has pretty much the worst calling conventions. You can use rcx/xmm0, rdx/xmm1, r8/xmm2, r9/xmm3, so for a C function signature

int64_t func(int64_t a, double b, int64_t c, double d, int64_t e, double f, int64_t g, double h)

Even though 4 general purpose registers and 4 floating point registers are available, you end up using 2 general purpose registers (rcx and r8 for a and c) and 2 floating point registers (xmm1 and xmm3 for b and d). rdx and r9, and xmm0 and xmm2 are unused, and the last 4 arguments must use the stack -- note that clustering the ints or doubles doesn't change that.

For the same function with the System V x86_64 calling convention, (e.g., Linux, BSD, macOS), you can put everything in registers rdi, rsi, rdx, rcx, r8, r9, xmm0-7, with some to spare. rdi, rsi, rdx, rcx are used for a, c, e, g. xmm0, xmm1, xmm2, xmm3 are used for b, d, f, h. xmm4-7 are still unused, but are available if more parameters are added to the function.

I haven't read the literature on this BTW, so I'm not terribly confident, but I'm guessing that on System V there are still enough scratch registers available for "general" code. High performance code where you're actually using all the lanes of your 128 bit xmm registers and so on, they should be fine on System V because you're doubling up or quadrupling up with those lanes, and often accumulating into a small subset of the argument registers anyway. So you just save yourself function call overhead.

Getting further off-topic, but if anyone is interested in how to apply "high performance" thinking to the common, mundane problems we have to solve daily, I highly recommend https://media.handmade-seattle.com/context-is-everything/. In particular, it's a window into practical SIMD, but it also makes some worthwhile "software philosophy" points as well.
