This looks like a great resource! Like others, I vastly prefer an example-based style, and the examples are really well chosen and very illustrative. I generally think I know my regexes, but I've already learned a few tricks. (Backreferences to match different delimiter options but not mixed delimiters is very cool!)

Feedback:

The highlighting of matches is slightly shifted to the left for me in Firefox 75 but not in Chrome (both on Ubuntu 16.04). The shift is subtle but enough to make me have to look two or three times at most examples, as the highlight covers half of the character before the match and only half of the last character in the match. Can I suggest adding Firefox to your test regimen, if you haven't already? :)

Also, on the Anchors page, I believe "carat" should be spelled "caret."

Thanks for this once again! I will definitely be revisiting this site to brush up and learn new tricks. Especially lookaround, which I have never quite wrapped my head around!
Regulatory capture is special interest groups in charge of regulating themselves. Of course private movie theaters are the ones who sponsored the bills saying production housing can't own movie theaters, it'd be bad for their business to have to compete and not have access to all movies. Regulatory capture can be sensible and still massively benefit special interests.
I loved POV-Ray in the 1990s and early 2000s. The thing is—it’s ridiculous to try and make something remotely complicated or organic with POV-Ray, unless you are using some modeling program that can export to POV-Ray format.

POV-Ray scenes were dominated by procedural textures and geometric primitives, for the most part. The rendering engine was very strong, and supported all sorts of features like area lighting, depth of field, motion blur, global illumination, caustics, volumetric lighting, etc. All of these were supported way back in the day before they became more common in other engines, and of course, using these features made your render times horrific back on early-2000s single-CPU machines.

The way a lot of us did modeling in POV-Ray was with a pencil and some graph paper. Without a good modeling program, you were setting yourself up for a ton of work. So I’d try to get the most out of simple models, and make it look as good as possible with lighting.

Funny enough, if you are used to CSG then you may need some time to adapt to modern workflows. Blender supports CSG, of course, but there are some caveats that you should pay attention to.
On the other hand if google had stuck with their first name -- BackRub -- I do wonder if they'd have had quite so much success. And I find it amazing that I wonder this given the experience of using google initially was like you had grown a super power over night. But maybe usage would have spread slower and given competitors more time to catch up.

You very conveniently skipped that you cant build async /await in C without modifying the language.

You also failed to show how parser combinator grammars such as yacc/bison/BNF forms are basically just imperative code.

Anyone know a good alternative to this that isn't meant to be fleet-scale? Getting OBD data over Bluetooth is widespread enough, but their service also made it super easy to generate mileage expenses. Also downloading a CSV of all my trips made for some fun data crunching.

One thing confused me about this. In major American cities bike theft is incredibly common, to the point that the police won't help at all.

I've had bikes repeatedly stolen out of locked garages at home!

I'd never buy a bike that was worth any reasonable amount of money, my commute pre-covid was a good candidate for an electric bike, but no way would I spend more than a 2 or 3 hundred dollars on something that will get stolen within 3 years.

Is bike theft just less of a problem in Belgium?

Hey folks, author of Dgraph here. If you're interested in the design details of Dgraph, and have the appetite for a very technical research paper, please check this out:

https://dgraph.io/paper

I'd like to thank Kyle in doing another round of testing. Some of these bugs that we fixed (in 2018 and 2019) were very tricky edge cases -- it's incredible to see Dgraph running so much more stable now, under all varied failure scenarios.

Let me know if you have any questions, I'm around to answer.

apt-listbugs is really the main one for me.

When I upgrade, I pay close attention to the package change lists. If packages are set to be removed, especially a lot of important looking packages, I cancel the upgrade and investigate. Usually this means that something has gone wonky with dependencies, or not all of the packages that need to be upgraded in lock-step are available yet. Usually this resolves itself after a few days, but sometimes you can coax a partial upgrade if you find the culprit package and hold it.

Speaking of holding, apt-mark hold/unhold (or equivalent - I think there might be a better way to do this now) is your friend. I usually end up holding packages like the ones mentioned above that erroneously want to remove half the system, as well as any packages that apt-listbugs complains about, unless I've reviewed the bug report and am okay with it. I'll periodically unhold everything (apt-mark showhold | xargs sudo apt-mark unhold), then retry an upgrade to see which bugs or dependencies have been fixed, and then hold any remaining offenders again. Usually this will end up "releasing" package upgrades in chunks depending on the dependency graph.

Apt should probably be louder when big parts of the system get marked for removal. I think this the primary way testing/unstable systems end up breaking, and it's completely avoidable.

In my most recent position, I worked remotely alongside 5 other developers located in the United States and France to build and maintain the largest online marketplace for short term real estate. The company was forced to lay folks off due to the collapse of the retail market.
I'm passionate about building a strong culture of accountability, collaboration, and teamwork on the teams that I'm a part of and I'm looking for my next role. I've been happily and productively working as part of a fully distributed team for the last couple of years so I'm primarily interested in remote positions, but I'd consider relocating for the right management/team-leadership role. If you think I would be a good fit for a role with your team, let's chat.

(author of Dgraph) We want to improve full text search, to bring it inline with Elastic Search. A lot of people compare Dgraph against Elastic, because they'd rather just have one solution (Dgraph) instead of two.

You can go every 26 month. If you can produce fuel on Mars going back is way easier then going from Earth to Mars. You don't go from Mars Orbit, you take of from the surface directly to earth where you aerobrake. No Orbit operation on Mars needed.

> It’s clearly viable, but for that kind of DeltaV across such a long trip, solar powered Ion thrusters have several significant advantages.

Not really. The only potential use for ion thrusters is for cargo transport that is not time depended. If you do that you need to figure out how to do the landing, so the complexity is just higher. The thrust is just to low compared to a few powerful chemical engines. If you can refuel in earth orbit for cheap you are gone be way better off with chemical.

If you move on from chemical, nuclear thermal is by far the best option.

Food is really not the problem. The mass of food needed for humans is pretty small. Clearly you want to produce food on Mars eventually but its not a priority for the first 5 to 10 years. Refuel on Mars is by far the biggest mass saver.
And this is also true of cars, except the maintenance and parts on cars are much more expensive. Probably most Americans don't think much about this much as they drive and service their cars regularly.
With Intel DPDK now in a fairly good state, it's actually fairly possible to get very attractive performance in userspace. You can leverage CPU instructions for crypto primitives when available to speed things up too.

The amount of TCP hardware offload in linux right now is actually fairly limited. Kernel developers have largely rejected true in-hardware TCP stacks for a while now (although you can get this functionality with high end NICs and custom kernel builds). That said, since QUIC generally reduces the ack frequency it should be possible to match or exceed TCP with hardware offload. Especially when you look at total throughput with many streams open.
Would it be possible to design a criminal justice system that recognizes only a bounded amount of crime?

I.e., a legal system where the "choosing" of which cases to go after, is somehow built into the letter of the law (maybe with a high bar in the indictment process?), such that everything that is illegal by the letter of the law is something necessary to go after (the societal equivalent of a showstopping bug—serial killers, for example), rather than just a "nice-to-have" that could be indefinitely deprioritized.
Hi Hacker News!

I’m Evan! Like so many of you, my grandparents are currently stuck at home. With all the shelter-in-place orders, it has been really hard to see people over 65, and grandparents are extra lonely right now.

Biking sucks for downtown urban areas due to crappy drivers, bike thieves, and more accessible public transportation.

However, for those who aren't well served by public transportation it seems like a great way to solve the last like problem. On foot, a train station 2 miles from your house isn't practical. On a bike it is.
If you are building such things because it's what you want to create, sure, but if you're doing that because you are just looking for something that will grow, that is a fairly unrewarding strategy for doing a startup imo.

Gordon is a little too frustrated with bullshit even for me, and I should carry an epi-pen for my bullshit allergy.

Same here in London. We still can enjoy relatively car free roads, but this is definitely going back to "normal" where cycling becomes quite close to a Russian roulette type of activity... I'd like to commute on a bike, but I'm not that suicidal (I've clocked in 20k km on London roads commuting, but now it's too far, too dangerous).
12-speed chains are exclusive to the high end MTB space; no commuter bike is going to have that. Even high end road is still mostly on 11-speed. They're also not any weaker than wider chains:

Any encryption scheme will cause the file to look like random data. All that means is that seeing the file contents alone is not enough to prove the crime. It doesn't mean that the file contents become free of infringement.

If you bike every weekday: (52 weeks/year * 5 days/week * 1€/day) + 12 = 272€.

Add in however much you think these bits of hassle are worth:

• various amounts of time spent looking for a bike, especially if you go somewhere they don't tend to cluster and someone else took the one you're using

• bikeshare bikes are typically kind of heavy and clunky, possibly with solid tires that don't blow out but transmit every bump in the road to you

• bikeshare bikes are usually one-size-fits-all, which I guess is fine if you're the perfectly average size, but they're always too small for me; an improperly-sized bike is harder to ride and can create more strain on your body

And of course you can subtract maintenance costs, I'll pull 50€ out of my ass as a yearly number for that.

I think the explanation the Cantillon effect gives is wrong. The monetary injection spreads uneven not because the effects on purchasing power are delayed between different groups but because it mostly increases the value of financial assets. And rich people have a larger share of their wealth in financial assets. Most of the wealth in the lower income percentiles is probably in consumer goods (appliances, cars, etc) and very little in savings / financial assets.

This was not a counterpoint point at all. More like bike-shedding meets strawman.

There has not been any counterpoint to my comments yet, actually. My guess is because people have an emotional and ideological take on this: Cycling is good so giving money to fund repairs of bike has to be a positive measure as well. Except that it is not based on any economic or rational reasoning. I'm pretty certain that the only result will be to fund superfluous purchases or upgrades because that the standard effect of windfall subsidies.

This is partially selection bias. Most successful niche businesses prefer to avoid publicity because it might encourage more competitors. It's better to fly under the radar with minimal competition as long as possible. The more people who know about your profitable niche, the more your margins will be reduced in order to remain competitive.

Yet when it comes to generic "shovel" services like SEO, having your name and business spread across the internet is free publicity and free reputation building. The product and market are already mature and saturated, so there is no worry about new competitors. Instead, it's a game of getting your name out there as much as possible. The more people see your name on famous podcasts and websites, the more value they assign to your services.
