> I have seen emails get leaked from hacks or just plain "we share only with trusted 3rd parties!" buried somewhere.

This is why using a different email with each website is glorious! If example.com leaks my example.com@«my domain» address, I can enable stricter filters for that address.

> I suspect if they become popular enough it's only a matter of time before spammers add some sort of "this looks like a catch-all account type email, try sending random stuff" to their logic.

This isn't game-over, either. As I noted, if this ever starts happening, I'll change my sieve filter so that any address without a filter rule gets sent to the trash, instead of my inbox. This does mean I lose the "zero friction" benefit, but adding a new address would still be just a single line in a text file. And it's much less lock-in than using the web interface of some given email provider to set up new aliases, since I can copy my filtering config over to any provider which supports sieve filters (and wildcard addresses).

That said, I don't think this will ever be a problem. Because "this looks like a catch-all account type email, try sending random stuff" is a pattern that makes you very easy to identify as a spammer. Given the possible address space, I don't see a scenario where the chance of hitting a real mailbox is worth the risk of blowing your cover and getting your mail server blocked.

Sadly, neither Inkscape nor GIMP still supports CMYK color space natively which makes these tools difficult to use for commercial printing purpose. Beside that Inkspace is pretty cool piece of software.

By "gone", I think they mean the project/website associated with the "Show HN" is gone/failed.
This article opened for me a Pandora's box of curiosity.

For anyone interested, this is an excellent introduction to some of the concepts: https://web.archive.org/web/20060210112754/http://cns-alumni...

Fourier analysis is currently used in "Image processing to remove periodic or anisotropic artifacts such as jaggies from interlaced video, strip artifacts from strip aerial photography, or wave patterns from radio frequency interference in a digital camera."

Also, "JPEG compression uses a variant of the Fourier transformation (discrete cosine transform) of small square pieces of a digital image. The Fourier components of each square are rounded to lower arithmetic precision, and weak components are eliminated entirely, so that the remaining components can be stored very compactly. In image reconstruction, each image square is reassembled from the preserved approximate Fourier-transformed components, which are then inverse-transformed to produce an approximation of the original image."

Elasticsearch is fine for time series data. A lot of tasks are actually easier with time series data. You add a field called `@timestamp` to your documents and a lot of analysis becomes possible, like date histograms, date range queries, ML jobs, etc.

Immutable time series data like logs and metrics are a great fit for Elasticsearch due to the way Lucene stores data. Documents in Lucene are immutable so an update in Elasticsearch is creates a new document and places a tombstone marker on the old one. Immutable data means you don't have to tolerate those inefficiencies.

Dashboards don't load the entire dataset by default. I can't remember what the exact default time range is but I think it's ~15 minutes or so. They're fairly quick to render in Kibana.

Elasticsearch is a great tool for observability data (logs, metrics, and APM data). Elastic's tooling makes a lot of this really easy in most cases.
Ask HN: How did you recover from burnout?
Specifically, how did you delete the connection your brain made between activity and failure?

Years ago, I tried to create my own little business. I failed. I tried to be persistent and worked till fatigue, depression, and anxiety attacks stopped me. I got into therapy, slowly rebuilt my life, feel pretty good now. I would even say it was a valuable experience.

However, it seems that the connection between writing/coding/building something and failure persists. I think I am not without creativity. I would love to try some side projects. But whenever I get excited about some idea and sit to work on it, my brain treats it like poison. The resistance is so strong I never make any progress.

I remember working on something all night and enjoying it so that when I finally went to bed, I was looking forward to continuing in the morning. How do I get this back?

This systematic review and meta-analysis suggests relatively small or neutral overall asso- ciations of butter with mortality, CVD, and diabetes.

These findings do not support a need for major emphasis in dietary guidelines on either increasing or decreasing butter consump- tion, in comparison to other better established dietary priorities; while also highlighting the need for additional investigation of health and metabolic effects of butter and dairy fat.

Thank you. I think something that a lot of the tech world can take note of.

I was also terrible at confrontation when I was younger because I have affirmation as a love language and confrontation doesn't fit too well with that.

In the same way, I had to discover to deal with my baggage so that confrontation was not awkward if handled objectively. It is possible to critique without criticism and most of all, it is entirely possible that other people might be able to teach me something ;-)

I still find my self looking-down on people who are often less "technical" and who therefore struggle to understand logical things but then I struggle to enjoy myself, to throw caution to the wind sometimes and to do things that I can look back on and say "I'm glad I took that risk".
thank you for sharing, this was a fascinating read. Especially not giving up after a failed launch and turning it into something great..

Just wondering, when no one noticed on HN and PH, how did you get your first users and eventually grew bigger?

My team and I launched a workflow tool which was not ready for the dev community yet, just recently [https://news.ycombinator.com/item?id=28392756].
Low engagement on SHOW HN was somewhat expected, but similarly to your case, we're launching again soon.

Hi Johannes here from Gitpod. Copying the answer from our launch post: https://www.gitpod.io/blog/openvscode-server-launch#how-is-t...

Gitpod is all about provisioning and orchestrating ephemeral developer environments (think about it as a resource efficient and powerful orchestration platform for your dev envs).An IDE is just one building block of a working cloud based developer environment, in addition to the operating system, databases, compilers and all the other tools you need to be productive. At Gitpod we want to support the IDE or editor you like best, and providing VS Code through the web browser is just one possibility. Alternatively, you can access your Gitpod workspaces through SSH, local VS Code and soon your favorite Jetbrains IDEs.

If you have a machine somewhere which you would like to access with VS Code through a browser, check out OpenVSCode Server. If you need control over your infrastructure and would like the orchestration capabilities that Gitpod offer you can self host Gitpod.
Did you hear the story about the statistician who tried to walk across a pond that averaged 1m in depth and drowned?
I agree with the author's general sentiment. Things are expensive in America, but America is a big place.

There is a 12:1 difference in per-capita income between the highest and lowest income counties in the U.S.

There is a 8:1 difference in average rent by county in the U.S.

Energy costs, same thing. When I lived in NY, in an old house in Westchester, I am pretty sure we paid 800 to heat our house one month (the worst month in the 5 years we lived there)
Now in Eastern WA, for a similarly sized house, I don't think we've ever spent more than $100 in a month. Also, when living in NY, my income was higher, but our income:housing-cost ratio was 3:1, and our total cost of living just about broke even with Income.

Now in eastern WA, I make less money, but our income:housing-cost is about 8:1, and we're way ahead each month.

I guess my point is that the cost of living vs income is a major problem, but only for some. Predominately, those people live in or around the more expensive cities.

Sadly, those people are likely stuck in their high-rent, low-income situation, because they, as the author mentions, are going backwards every month. If they can't get ahead, they can't afford to move to somewhere with a better income:housing-cost ratio.
$80 a month is pretty steep for a basic small business site. You can DIY it for less than $20 a month with a variety of tools (Wix, Wordpress, etc.) Nobody spends $3K on a site anymore.

should the server calculate the hash before the miner does and check whether they are equal?

Yes, this is how it works.
Scaling has been tricky. Finding a database system which can handle the load was the hardest part. A single Postgres instance buckled quite early on. Later I tried Cockroachdb but it also was not up for the task. Now I'm running ScyllaDB and it's handling tens of thousands of queries per seconds like a champ.

Content moderation is already a big problem. It's what I spend most of my time on nowadays. There is a lot of crazy shit getting uploaded. Abuse reports are flying in from all corners of the internet. I'm working on automated systems for processing them. The most annoying part is that a lot of copyright management firms don't sign their e-mails with DKIM, so I can't verify that the sender address was not spoofed. This prevents me from fully automating the e-mail responses.
Same. You can say I'm easily influenced, I don't care :-)
>In what way is it reminding you of that incident?

It's just in group signaling. "Hey this reminds me of <vaguely related thing>" is a more polite way of saying "look I know about X, I'm like you, gimme dat virtue points"

You see this on literally every virtue points (i.e. up-vote) based form of social media that's big enough that any given participant can blend in with the crowd.

The behavior is endemic these days you can't even post a picture of a rotten and falling down deck on the internet these days without some jerk derailing everything by dropping a link to the wikipedia page on the hyatt regency and then several more riding their coattails with quotes copied from the page.

I love Inkscape, but I wish it's interface wasn't stuck in 2005. Since that time a lot of apps appeared that did greatly improve user interfaces, making the user 100x more productive using them.

Of course, I'm talking mostly about Sketch that pioneered an approach with a lot of tiny things done right. When transitioning to Sketch from tools like fireworks or Inkscape, I was amazed how right they did the work with coordinates, half-pixels and masks, and various copy-duplicate mechanics. Guys, it is OK to steal interface innovations from Sketch! Figma did it all the time, and so can you!

Not OP but that is already a LOT of information. Usually you see which methods are hogging CPU which shouldn't, and optimize those. The nice part is that you can drill in at various levels of granularity. Really bleeding stuff would be stuff like minimizing copies and sharing memory within Kernels, vectorizing, etc.
But, if that article is correct, (“When you buy a headset like Oculus Quest, it is meant for consumer usage, and theoretically speaking, you can’t use for commercial purposes (exhibitions, training applications, VR cinemas, etc…). Yes, I know, we all use it for commercial purposes as well and for sure Oculus won’t enforce the licensing in the short term, but if you want to play exactly by the rules, you should buy a Business Quest for every enterprise application.”), you can use it commercially! That’s a steal!

I have much the same experience as you, but two points:

1. Those pointers to your issues are only helpful because you have the resources to work on them — dredging up issues when you lack those resources often breaks people. Being “forced to confront” when you’re at risk of being overwhelmed is a genuine threat you’re pretty cavalier in dismissing. Can that lead to negative cycles? Of course — but most mental illnesses are a reasonable defense or reaction applied unreasonably. Unwinding that requires understanding the point of the mechanism.

2. I’ve found that while this process has made me feel better and address my own baggage, I still just don’t enjoy most people — and find the whole ritual of dense living exhausting. I think you may be conflating unblocking your emotions with the outcome of your personality, once unburdened. You felt that way, but other people will feel differently.

To me, hell is the constant barrage of other people trying to assert themselves in and control my life, when I’m forced to be around them — often, using me as a springboard for their own emotional journeys. I don’t mind it as a general principal, but I do mind being coerced to participate when I’m not feeling it.

Actually, that'd be great, especially if it could resize/add logos/etc and cache variants.
This is what I did a couple of jobs ago. I was a technology leader in a startup, and installed in myself to track Where TH did my time go. After some months I got some nice charts and interesting insights. I showed those to the people in my team and told them that if anyone wanted a license I would pay for it, but it would be for their own personal use (nobody would have access to their data). A couple of people approached me to get licenses.

This is kind of similar to the GitPrime/WayDev and similar software: The insight is actually quite good, but the moment "The Boss" uses it, it becomes a control mechanism. The best way to take advantage of it is if it is provided as something completely personal.
Microsoft Store: More apps, more open
The article was brought to you by: CEO and cofounder of Elation Health, which offers an electronic health records system for independent primary care that strengthens the relationship between patients and physicians.

Healthcare in the US is completely broken. Primary doctors do not have an incentive to produce good results. They are being squeezed by the corporate overlords and insurance companies to do bare minimum with patients. Each hospital network has their own medical records software. The care is extremely fragmented.

Records need to be centralized. Primary care physicians should be required to spend more time with patients and not be punished for it. If issue is difficult they should be allowed time for research, but that doesn't make money....seeing patients does.

In the end, get rid of the middle man, the insurance companies. Quit paying specialty doctors $600k, and offer free education. I would love to go into medicine to help people, but I'm not going to go into debt, grind for free doing insane hours and hope to get a decent job in the end. If I could get a free medical degree and a salary of around $150k I would do it in a heartbeat. Current healthcare is so commercialized it is disgusting.
Glad to hear of your experience too. I wonder if there is any research being done in this area? Seems like an interesting opportunity to explore and understand memory in a new way.

Maybe I am Cynical here... But I guess I know why they do this.

You see, as long as there is no law forcing competitors to do what they themselves do, they can claim to be more green/planet concise then all the rest.

This chimes well with a certain cohorts of consumers. But if all competitors where forced to be equally “green” this advantage would fall away

As cool as this looks, you really need to answer the burning question that a small business owner (such as myself) will be asking when they look at this: What is the value proposition here that is not also offered by e.g. Squarespace for a fraction of the price?

At the moment, that is not a question I can see an answer to.

Actually I was careful not to call you a troll. I said your username was trollish (meaning that it adds a provocation to every thread it posts to), and I said your repetitively bringing up the Holocaust was at minimum concern trolling (I could also have said sealioning)—the point being that going on and on about how you're not questioning the Holocaust is weird, like insisting you're not a cop: https://www.youtube.com/watch?v=qBE9TZP26FI. It's guaranteed to provoke (hence concern trolling), and it inevitably brings up darker associations, because extremists are known to play games with this sort of thing—non-denial denials, etc. We don't want any of that here.

> You have banned me several times for criticising socialism
> You just don't like criticism of leftist ideology

People make up this narrative about why we ban them all the time; ideologues on the opposite side say the same thing. None of it is true. You can tell that in two ways: first, the claims are completely contradictory (https://news.ycombinator.com/item?id=26148870), but they rely on the same logic, so the logic must be wrong; second, all you have to do is scroll through past moderation comments to see that we moderate people on all ideological sides—and get flamed for it from all sides, too.

Since we've had to ban you several times, it's probably time for you to realize that you're simply not using this site as intended.

It doesn't help with breadth-first searches either. A non-degenerate tree of depth N will use O(N) space, and that space will be on the call-stack if you use a recursive algorithm to access it.

As long as you use less than 1 page per activation record though, most modern libc implementations behave safely under unbounded recursion as they will allocate a guard-page around each stack.

[edit]

It would also be useful if the compiler could warn about activation records larger than 1 page. Absent alloca (and deprecated c99 VLAs), that should be statically knowable.

I used to work for a manufacturer of mainframes in the 1970s. The installation guys told me about upgrades. They would carry in big sealed crates. They would put paper over any windows in the doors etc. The crates would be opened to reveal food and drinks, books and magazines. They would open up the mainframe and flick the 'double power' or whatever switch, set some tests going and have an enjoyable relaxing day.

Plus ça change.
Fair point. Thanks for answering.
