Theory in User Research: How Levi-Strauss Redefined Browser Workflow
The quote from the post I replied to mentions “the battle to feed humanity”. Distribution is very much part of that battle; otherwise it could only be considered solved in the purest theoretical sense.

Ask HN: US Health Insurance for Startup Founders?
I would like to leave my corporate job and work on a startup idea I have. If I were to do this, my health insurance premium will move from around $300 a month I am paying through the company to $1550 under COBRA. What are my other options?

Can these devices tie in to existing hi-fi systems (either via bluetooth, or physical outputs)? Or are you tied to the teeny-tiny internal speaker for your music?

You can use such a hashfunction, but it'd not be a good one for general purpose. Remember that hashtables, and also our hash-indexes, use buckets / ranges of hash values to keep the hash-table at reasonable sizes. If you don't use a hash function that has a good bit perturbation, you can end up with a lot of values in the same bucket.

Consider e.g. the common implementation where buckets are determined by masking out either the lowest or the highest bits of the hashvalue. If you mask out the highest bits and your values aren't sequential (pretty common), you end up with a lot of collisions. More extremely, if you mask the low bits and shift, if you only have small values everything ends up in the first bucket. Therefore what you want is a hashfunction where a one bit change at "one side" of the input value, is likely to affect most of the remaining bits.
Just noticed that the original(?) website of this type, http://www.isthesunburning.com, seems to be gone. In fact the last working snapshot on Archive.org[1] is from 2010. Guess I'll never know if the sun is burning now.

In 2007, I sold my business. In 2008, I put a bunch into the stock market and property. It was comparatively dirt cheap. I made a killing.

I'd do the same with cryptocurrency, but I can't figure out how. My 2008 investments were pretty risk-free. Of course the economy was going to recover. It always does.

I've no idea how to do that with cryptocurrency.
How often do such charges not even get filed?

(that is, where someone has violated the law with some mitigating circumstance)

How would that aspect be addressed?

Or cases where charges are filed as a formality and end quickly?

There seems a strong possibility that the Supreme Court only hears a small number of odious claims of the defense.
> Finally, hash indexes always require that the found row be confirmed in the data table, even for simple existence queries, since the keys themselves aren't stored in the hash table. (This is why hash indexes can't be UNIQUE.)

I don't think that's really true - even for btree indexes the heap is accessed to check row visibility. That's necessary because postgres doesn't store visibility information in indexes. There's imo no really big problem making hash indexes support uniqueness - it's "just" work.
300 lbs of urea or .65 boe of NG (1 bbl of oil = 20 gallons of gas and 11 gallons of diesel). So let's just say 20 additional gallons of fuel to account for the N

Edit: the land would be planted to wheat if not planted to corn. Wheat uses approximately 80% of the N as corn. The land wouldn't sit idle.
> I'm wondering what the issues are here and why stroke order was useful in the 90s but not considered so now

People expect more from technology.

So while in the 90's it was amazing that technology could get the correct character if you clearly wrote each character with the correct stroke order, today, people expect to be able to hurriedly scrawl (possibly in cursive) and have the system get the right character. Those are two very different problems.

See for example the images of cursive characters in the linked article. They are very common variations, containing simplifications, but they don't follow anything like the correct stroke order for the character except maybe in broad terms such as writing from left-to-right, or top-to-bottom
That's a hash join which has existed in Postgres for many years. Hash indexes are unrelated.

The primary use case of hash indexes is situations where the indexes fields are very large. The hash index uses a fixed size regardless of the width in bytes of the key so it "wins" storage wise when the key is wide.
I updated the title to mention Sendy, since a lot of people know that and it's quite an apple-to-apple comparison. Thanks!
How much do you know about McDonalds? These aren’t artisan burgers. I see no reason why a dentist, should he or she have the desire to do so, couldn’t be trained to perform the task that is being a cog in the McDonalds burger factory in at most a few days. On the other hand, training to be a dentist is going to take a lot longer.
Could you explain the limitations? Why specifically 3 servers or 24 cpus? Totally arbitrary numbers, or linked to something?

My business partner's father (ZL2AL) passed last year and I know he'd be chuffed to see all this HAM talk on HN :-)

He demoed the process to me last time I saw him (back in New Zealand). It was amazing to see the speed with which the he (and the other operators) could relay messages around the world.

He wrote a bit about his many adventures on his blog (http://www.zl2al.com/). I guess there may even be other HAM operators on here that knew him.
People only care about what they get to take home.

If you get hit with 30% by one institution, another 2% by the same institution in another category, and then another 10% by your state, people are going to say they got taxed 42%.

I have lived as a resident in 3 states. The combination of city, county, and state taxes has always been around 10% for me. You are right though, I could have emancipated myself while a minor and moved to Florida where there is no income tax. I could have chosen a different university where I didn't have a scholarship. And subsequently I could have lived anywhere after that and enjoyed the lowest tax brackets because of my lower salary.
I think the win for that kind of scenario is smaller than you make it out to be. I agree on memory usage, but the concurrency argument seems largely faulty because you at the same time increase page-level contention on a shared resource (postgres' buffer cache).

I personally want a lazily filled hash-join / something like a index nested loop join that has a fixed size cache for both positive and negative lookups.
The entire article has far too many errors. Most of the info is correct but they make several mistakes including lots of typos.

I will have to check that one out! I just finished the first lecture in "Our Night Sky" for my stepdaughter's science report. Very good content. I really like that all of these people sound like they lead the local chapter of Toast Masters.
I went to get my U.S. Technician license (I've had a Swedish CEPT2 license for a long time but never been very active) after studying a bit online, and after passing that they asked if I wanted to try the General test too, since I was already there. I did, and I passed. (Did the same with Extra, but didn't pass that one.)

I would certainly not be comfortable with actually operating a HF rig without doing some prep work, but it seems to me that an active ham would have a reasonable chance of squeezing by the General test if they gave it a chance.

> That's a hash join which has existed in Postgres for many years. Hash indexes are unrelated.

I think the OP ankrgyl is aware of that. To quote:

>> It is quite common to build a hash table over a subset of the inner table of an equijoin. This is (a) slow to construct and (b) memory-intensive (especially if many of these queries are run concurrently).
From a 2015 NPR article [1]: "The Red Cross says it has provided homes to more than 130,000 people, but the number of permanent homes the charity has built is six."

I find it interesting that his results inspired changes in 30,000 schools but the article mentions no follow-up studies.

Did nobody recognize the research opportunity inherent in launching these programs across so many schools? I assume the original studies used small samples. I would have been trying to collect new data from this large sample to re-test the original hypotheses.
One of the requirements is that you have to actually add a chain redirect to the www subdomain if a dns record for that subdomain exists.

That’s actually not a very good practice. You’ll get http non-www to http www to HTTPs www,for example.

Why is this a requirement for the preload list?
However, if police are willing and legally able to do that, then I think basically all phone security goes out the window anyway.

The biometric attacks being discussed here are ones that could quite plausibly be used against you in many/most districts in the US, and be totally legal for the police to use.
I couldn't login to the app, I think you should provide a demo account with an ideal data for people who just want to give it a try.
If you don't get your technicians license and have the opportunity to, I think you're crazy. It's something in tech that doesn't get enough love anymore. It's immensely valuable and actually a fun change of pace from SaaS.

I like the repeal of AMT. Silicon Valley's equity options offerings just got a lot more attractive!

I don't like removing the state tax deduction from federal tax. With federal income tax not being marginal anymore it is the real percentage deal, and then you have to throw state tax on top of that? Yikes thats a big tax increase.

I LOVE the lowered corporate flat tax for entities. For some reason he throws in pass through entities like single member LLCs, which suggests that all the personal income tax brackets are a complete red herring since anyone can just form an LLC and get taxed at 20% instead. How is that not the main discussion?

It could all be balanced by the trillions in repatriation. Even though the US government could not count on getting trickled down tax revenues from all that money back in the economy, they could count on a lot of being parked right back in US treasuries, which is basically the same money in a different account.

This blows my mind. These programmers can implement quite complex contacts-financial-exchanges on top of a quite complex distributed system, but then fail to sanitize user input in their web interface. It makes no sense.
Ah I think I misread that section with the "nested loop join" stuck in my mind.
100% agree on unit testing regex, but spending a minute to type a detailed comment that saves sometime the extra time of navigating to and reading several unit test cases is worth it. If someone is modifying the regex the tests are essential, but for someone just reading the code why not save them the time?
True, but in my opinion, Uber isn't dead until it's not one of the leading choices in car sharing apps. In just about every metropolitan area in the US "Uber" already has household name recognition, and all it's disgressions haven't changed that.

> but reading a fluent writer's handwriting ("unconstrained", as they call it in the article) is nigh impossible.

It is when you are starting out, but it's not so bad once you get used to it. The best way to learn to read Chinese handwriting is to learn to write Chinese handwriting, and I don't just mean practising writing by hand, but to work through a textbook aimed at teaching cursive Chinese.

This book is a good introduction in English [0], and if you are comfortable with Chinese only, this book is excellent and also far more comprehensive [1].

Once you've gone through those books, you'll be able to read most handwritten stuff without too much struggle.

Sorry, I meant DNSCrypt (I thought I edited it soon enough). DNSCrypt is meant to be more about the last leg encryption/integrity/authenticity guarantee (compared to DNSCurve atleast) between a client and (caching) server.

I agree with you on the DNS over TLS part. It is definitely a great idea. With TLS, secure transport implementations are already done to death so I guess we don't have to worry about another. I do have a question though. How are you handling the DNS request for the initial TLS connection? I'm talking about this:

1. Want to make DNS query for X.com

2. Connect to personal-dns-server.com over TLS connection for DNS request.

3. Want to make DNS query for personal-dns-server.com.

4. ?

I'm asking this because your TLS implementation seems to be about the whole works - including the CA system. Which needs a CN. Which needs to be resolved (I initially thought it was just about the key neg + transport part of TLS with a hardcoded IP address in the config file)

About DNSSEC + DNSCurve/TLS. I just wasn't talking about privacy. Integrity was my primary concern. DNSSEC isn't widely deployed, so we don't really know which domain implements DNSSEC and which doesn't. So in the last leg of DNS reply, one can just remove the RRSIGs and make it look like DNSSEC was never implemented. Pretty much a downgrade (to nothing) attack.

Also, we don't have any way of warning the user if a RRSIG doesn't validate the A rec properly, so what's your plan on this? A while ago I had a similar idea you did, but more geared towards being an on-disk cache (check out pdnsd - sad it is unmaintained though) where I thought eventually it has to step into user alerts using the notification daemon.

As a proponent of de Broglie-Bohm theory, or pilot wave theory, (particles have definite positions and are being guided by the wave function of QM), I am pleased to hear of the book and enjoyed the review.

The reviewer was actually on my thesis committee and he always had an air of excitement with regards to this material as well as clarity with regards to both the philosophy and mathematics.

As someone familiar with the material, I can hear within the book the very common themes that proponents of dBB often have to say. Without having read it, I can't comment on the book's clarity of presentation, but it certainly sounds like all the elements are there and more perspectives are always welcome.

The issue has always been in getting people to try to accept that both standard QM and several of its alternatives really do not have an adequate description of reality in them and that this is a problem. I imagine the chapter that gives an in-depth discussion about what one wants from science is the most important novel contribution from the book to the field.

If you are curious about the strangeness of QM, then you should read the review and probably the book.

Just a note, as I have written elsewhere, that dBB is a theory that has been proven to have existence and uniqueness of solutions, handles identical particles in a very natural way, handles spin simply, generalizes to the Dirac equation, generalizes to QFT settings, has numerous proposals on integrating with relativity, and, quite recently, has led to some promising directions in resolving the issue of divergences associated with renormalization.

The strength of PHP is the fact that you can get php hosting for almost no money, that takes no effort to setup, is shared but isolated, and is almost always portable

A programmers response is “I can throw Django in a container” or “I can just buy a digital ocean droplet”, and that’s true for a Developer, but it’s like putting Linux on your grandma’s laptop - you can maintain it, but the target audience can’t

The reason people build sites in PHP is that the people for whom they’re building the sites can trivially support it. Forever.
I'd love to help but 3 weeks is a huge commitment and I can't leave my job that long. I think they may get a tremendous response from the retired folks in the ham community.

I've been a ham since I was a kid. There are so many different, interesting things to explore.

These days I find high speed telegraphy pretty relaxing and meditative, and I have a few ongoing RF projects that keep me going even when everything else seems trend-driven and silly.

And let's face it, radio wave propagation still feels magical. I could go on and on. Glad to see some PR even though it's for a sad reason.
We are working towards adding data replication as a feature in Wallaroo. To make that work, you need to allow for at least 3 servers so that was the bare minimum. We added the 24 cpu limit because we are trying to build a business and allowing someone to load up 3 massive servers and use all the enterprise features for free isn't good business.

We started with "low" numbers because we aren't sure what the right cut off will be and we would rather give people more in the future then realize we gave them too much.

If we decide that 5 servers/40 cpus is the right level then everyone who gets an increase will be happy. If we started at 5/40 and realized that the vast majority of use cases were fine at that level and wanted to lower that number, we'd be screwed and would ruin trust. So, we started with what we thought was a nice low minimum and as we go forward, we'll potentially raise the limits.

It was at least partially informed by a POC we did for one of the major US banks were we met their targets with 5 server and 30 cpus. It was the sort of application that we think is reasonable for us to get paid for (so we can keep building Wallaroo) so that also acted as an upperbound for our early discussions.

In the end, we want people to be able to use Wallaroo and get value out of it. And we want to be able to build a business and keep building this thing that we love. And as I said, we want to be cautious and make sure we are always in the position to give away more rather than having to take things away.

There are features that might eventually become 100% free and open source as we move forward. What we want to avoid is ever having to close the source on a feature.

I hope that answers your question. Sorry, its been a long few weeks polishing up the first release and it's been a very long day today so I'm a little tired and rambly.
If I just want to use your Apache 2 code how do I do that? Your documentation (https://docs.wallaroolabs.com/book/getting-started/linux-set...) doesn't seem to make any distinction between your open source and your commercial license code.

In an open-core model like Nginx there's an open-source edition and there's a commercial edition and there's clear documentation on what features are available on which version. There doesn't seem to be anything similar for Wallaroo.
