Melatonin works mildly well for me for a few days, but quickly stops working again, which is unfortunate. I will admit I also have some anxiety issues I need to work on.

For better or worse, a low dose of diphenhydramine hcl (12mg) has continued working for me for over a decade without needing to up the dose. My personal experience as far as habit forming goes: I only take it on work nights, and sleep just fine on weekends, or if I'm on vacation. My main issue with sleeping is the specific times I need to do it. If I'm able to sleep when I'm sleepy, and wake up when I'm not, then I don't need any medication. Unfortunately, that doesn't fit in with a typical work schedule.

That's the kicker. I have DeWalt, Makita, and Rigid brand electric tools. They all have different, incompatible (yet same voltage/amp) batteries and chargers, each costing as much as the tool. At least gas goes in any gas tool.

I'd rather they be regulations on the amount of pollution (both air and noise) allowed.

> If it ain't Boeing, I ain't going

I have mostly had the reverse sentiment; my experience is mainly based on 777-xxx planes, but I find the experience in those so horrible that I try to avoid Boeing in favor of Airbus. Every time when I cannot (like last week when I flew with a 777-300er) I get reminded how crap these things really are. Not talking safety but general feel and comfort; basically everything is worse; noise, seating, effects of turbulence etc. And I have noticed this across multiple premium airlines.

Another example for people to appreciate what a small latency advantage means. Consider SPX options which is a huge market. These “trade on CBOE” which is a Chicago exchange - but they physically reside in NJ. Now consider SPX futures - ES - on CME, physically in Aurora. Now imagine a 20-tick / 5-handle “sweep” in the ES — “sweep” is instantaneous price move (either up or down). Not “very fast” but exactly that - instantaneous. These happen as a result of large incoming aggressor order taking out many book levels at once. Sweeps can be of different magnitude (from just few ticks all the way to max allowed per CME’s “velocity logic”) - but they happen all the time. If you know enough about e.g. ES futures but have never seen sweeps, chances are you didn’t have access to the right tools/platforms. Even some supposedly-professional-grade platforms like TT or CQG do not show trade data with enough detailization to see these.

Anyway... why is this important? Because immediately following the sweep in e.g. ES, option prices in e.g. SPX options are temporarily way off. Dutch market makers have not yet moved their options quotes, because they do not yet know about the sweep - at least not in NJ. If you can somehow get orders to NJ faster than market makers can cancel their option quotes, you can take out hundreds of mispriced options. Multiple expires, dozens of strike, puts and calls. Very juicy bunch of stale quotes.

PnL... well that gets tricky. On one hand, just this one example is in theory worth hundreds of million per year if market did not respond. But the market will respond. That’s inevitable. No one enjoys being ripped off for too long, so if they cannot defend they will either leave the market or set quotes wide enough that they are never mispriced. The same goes for any other “latency arbitrage” game. I always love how people throw numbers like “this is worth X”, almost always assuming status quo. HFTs are very responsive to market conditions. If I run a strategy that’s been making money every single day for 10 years and all of a sudden it starts losing - I press the pause button and go do some serious analysis. So maybe I will let you have it for few hours - but after that if I can’t compete I’m out. So it’s not that simple.

I too suffered from insomnia regularly for most of my life (for at least 25+ years that I can remember) and just have managed to figure it out this past year. The major things for me have been light therapy in the morning, carefully watching my diet (certain foods cause mild digestive problems but this seems to really mess with my sleep), meditation and trying to control inflammation (again, partly through being very careful with my diet, partly by taking supplements and taking ibuprofin on rare occasion). The difference has been absolutely phenomenal. Your entire life changes for the better once you can sleep properly on a consistent basis. Glad to hear you have found something that is working for you.

Bay Area is better than most other places in the world..more diverse..more philanthropic and inclusive. Things grow and flourish in the Bay Area. We want everyone to succeed. We rise and we rise others. That has been my experience.

Maybe the friend just doesn't want to make a Serious Business out of this yet, maybe he just enjoys having this side project. Maybe he's still refining the physical design of these signs along with the software with every one he builds. Maybe he's got enough sources of chaos and craziness in his life already from work/family/the hairbrained schemes of his buddy Trevor and he just wants a nice little hobby where he can fiddle around. Maybe he just does not need a Side Hustle in his life right now.

Maybe this is just what he's playing with instead of putting together model kits, y'know?

It's quite possible to get lost in the weeds planning stuff with no forwards motion. It's also possible to make really, really expensive mistakes by plowing forwards. I've done both of those. There is an alternate reality where the friend has been looking for people to make this thing fast and cheap, and is now sitting on a pile of these things that he can't sell at a price point that will break even, much less make a profit, with an order of magnitude more money than he is comfortable losing sunk into them. And maybe that reality's Trevor just wrote a blog post talking about how this friend should have done their research first, what kind of idiot doesn't do their research?

I'm not saying forging ahead is always bad. I've done it a lot in the past. Sometimes it's worked out, sometimes it hasn't. And when it doesn't work out it is a shitload of hassle and stress and I can only take so much of that at once.
I think it is a well put together analysis, but I feel I'm missing something.

> FreeCache and GroupCache reads are not lock-free and don’t scale after a point (20 concurrent accesses). (lower value is better on y axis)

If you look at the graphs, they level out and seem to work best with more concurrent load, the exact opposite of what they say. Am I missing something?

Also, I think it would be valuable to see higher concurrent requests: with what I'm used to, 60 concurrent requests would be low - I'm interested in maybe 1-5k concurrent requests.
I think rpmcmurphy's middle sentence explained it: If you can, fly something else. If you're out of all flavors of "something else", then fly the 737 Max.
You have the right perspective on this IMO. Thinking about owning a home as an investment is foolhardy: very few people are going to get rich off an increase in their home's value, and only a few are even going to significantly increase their retirement funds after downsizing.

Houses are places to live, not investments. It's in all of our interests if they're as affordable as possible everywhere instead of pushing the equivalence of an arms race.
That’s our failure. Not theirs.

One huge failure is thinking that animals should care to learn anything we teach them.
So I've been involved in Fedora for as long as Michael has been involved in Debian, and I have attempted branching out into other distribution communities over the years.

To this day, the Debian community is the only community where I have not been able to get past the initial stages to get involved. And you don't have to look too hard to see that I'm in quite a few communities...

There's a lot of parallels to Debian and Fedora when I started in the project over a decade ago.

The clear divider in how the two projects evolved was that Fedora elected to implement a lazy consensus model for decision-making, and developed a culture with a bias for action and improvement. Debian requires full consensus (generally) and has a culture that favors inaction. This difference is what has kept me in the Fedora Project for over a decade, and I still enjoy working in that community and doing my part to improve the greater Linux community and ecosystem.

Over the years, Fedora shed a lot of its more complex processes and developed simpler tools and supporting infrastructure to make it easier to use and contribute to the development of the distribution and outlying projects. Over the years, I've seen us replace our buildsystem infrastructure[1][2][3], develop APIs and protocols for weaving tools together[4], migrate SCMs and create the first ever binary store system for Git[5][6][7], develop tools to simplify complex tasks[8][9][10], and build replacements to proprietary or overly-complex systems and support open standards and interoperable systems[11][12], all to benefit our users, our contributors, and our ecosystem. We've taken a similar hammer to our processes and structures so that we enable a wider range of people to be involved, representing their concerns and making our community healthier than before.

We're still continuing down this path of making it easier for people to leverage the Fedora Project resources for the benefit of the community with things like COPR[13], CI on packages with Koschei[14] and CentOS CI integration for projects and packages[15], etc.

That's not to say Fedora is perfect, mind you. It still has some technical and process warts. But I'm proud of the fact that our community is still actively trying to improve our processes, our tools, and our distribution. We're not afraid to make things better, and our community generally wants to make the Linux world a better place.

Great piece.
Last year, I forced myself to release something every two weeks

Out of habit I tend to check the comments here before reading the article, and um... I did a serious double-take between the title and your opening sentence. For about a second I just stopped and stared at the phrase, “even if it wasn’t finished” and just thought, “Wow... here’s a guy with high standards!”

Anyway, then I read on, sighed, chuckled, and read the (very good) blog post.

The preliminary report from the investigation of LNI610 disagrees with you: https://reports.aviation-safety.net/2018/20181029-0_B38M_PK-...

The AoA attack sensor was replaced prior to flight LNI043 (he flight prior to 610), in which the pilots declared pan-pan and had to manually override the auto trim systems (which include MCAS). Between 043 and 610, there was further maintenance that included flushing the pilot valves and cleaning electrical connectors, but the AoA sensor was not replaced between 043 and 610.

An aircraft that was repaired followed by one flight in which the pilots declared abnormal operation and performed 3 non-normal checklists should probably not fly again until they figured out what happened, and the next flight should definitely be aware of the incident on the flight prior. 043 faced and overcame the exact same malfunction as 610 - to me that indicates a clear failure. If you keep flying an aircraft that malfunctions on each flight, you're pressing your luck.
Essentially, we need a better system than capitalism.
I disagree. A few short more or less related entries in the glossary is not really "covering". A paragraph on smart pointers that conflates the concept with reference counting is certainly not covering RAII. None of these adequately address the deficiencies I mentioned.

Yes, I thought about hatchets, but the words are in relatively modern language. Nothing about muskets, powder, preparing to shoot. There must have been a lot of military training and discipline about the multiple lines of soldiers not only having continuous lines of fire like this describes, but also taking the right amount of time to prepare (load musket, powder and paper (what do they call that?) and fire. Keeping your powder dry, etc.
I noticed many people doing the same thing with "to do"/"to read" lists. They'll add items to their lists thinking they'll get around to doing them some day, not realizing that future me is probably just as lazy as present me, and if I were going to do something, I would have done it now.

So, todo lists become a bit of intellectual masturbation in the sense of "oh I'm not putting this off, I'm definitely going to do it, since it's on my todo list!"

I have on my todo list (see the irony) to build a mobile todo list app where tasks will disappear if not finished in a while, along with some other bells and whistles (they'll all move to another screen where you can't remove them and they'll mock you for ever), mostly as an art piece on this exact phenomenon rather than a useful app.
> who's suggesting that property laws are obvious?

Anyone who says they believe in "small government". That small set of rules always happens to include property laws.

> when someone gets choked out and killed by the police

That's also illegal. I would also advocate enforcing the law against law enforcement officers. Stronger than against ordinary citizens if anything.

> we think it's great because it's "punishes" the wealthy

Actually, I think that (even assuming that it were enforced) it does little to no harm to the wealthy. They have sufficient wealth that having less has almost no impact on their well-being.

> The problem is that political power is a zero-sum game, so any solution that gives those in power more power will only make matters worse.

Giving money to the poor gives them political power. Or rather economic power, which is a good substitute, and often what the rich use to gain political power.

Ideally we'd have some kind of basic income which provides this function directly. But other socially funded initiatives such as healthcare and education are also helpful in this regard.
Maybe because the whole thing was fabricated by corrupt law enforcement agents?

Depends on the area. Some areas are clean, some areas are filthy. The city I live in is successfully reducing the usage of plastic. They banned plastic bags that are at a certain thickness (the kind you get in grocery stores). Everyone uses paper/cloth bags and lot of times its reused. Now the government authorities are talking with restaurants to see how they can reduce plastic on take out food.

At home, they collect plastic waste once a week. We are expected to clean the plastic properly and dry it before handing them over. I was really surprised to see how much plastic waste we generate every week in our 2 people household. Seeing that has motivated me to reduce waste as much as possible.

They are also replacing all the city public transport buses with electric. They had some trial runs and electric buses made good amount of profit for them. So hoping to see an all electric fleet in another 5 years. Another major source of pollution is the 3 wheeler auto rickshaws (tuk tuk). News reports say they will also eventually become electric.
Quite a few players are trading on economic releases (eg non-farm payrolls, ADP, ISM, and so on) in this fashion. It’s often much easier to feed to algo because the release is a number (or set of numbers) vs some free-form-text thing. Competition is at a sub-micro latencies today.
Most "windows precision" touchpads are handled in Linux with just one module. Even Apple's Magic Trackpad can show up in system as a regular mouse (although with limited functionality).

I don't think this is true at all. A visit to Home Depot reveals a huge selection of battery powered tools, most of which are powered by one of four standard battery types, all of which have existed for quite a while. I have a whole bunch of Ryobi tools - and batteries from literally a decade ago, while an older chemistry (nicad instead of li-ion) are still compatible - and the reverse is also true.
In Washington state, all voting is via paper ballots mailed or dropped off at a voting location. You sign them. People end up having different ballots because your ballot is customized for the district you live in (unique city, school district, county, state combinations is a reasonable size). They verify your signature. You can track if you ballot was received (it's inside an inner envelope) and if your signature was confirmed or not.

This feels safe, and as they have the original paper, they can revote - but they have all the ones in the district in a box somehow.

This is all great advice. Ardupilot/Arducopter is heavy duty stuff, you can make a quadcopter/plane/whatever that will fly completely autonomously by giving it waypoints on a Google Maps interface. Highly recommended, I've built a plane like this and very much enjoyed the process.

In other words: It doesn't help at all against malware on the computer.

> The (state-provided) USB reader should have a small lcd screen to sum up the thing being signed "Vote for Ms.Ryjavik on election #123" "Vote for Yes on vote #432" and a confirmation button.

In other words: If the USB firmware is infected, it's still not secure.

> With these modifications, and the ability to check a cast vote has been received, you can have secure elections on insecure devices.

So, if you are using secure devices ... then you can have secure elections on insecure devices? In this scenario you aren't actually using the insecure device, other than for establishing a connection to the internet.

Or rather, as you described it, it also functions as the input device--but that is a security problem because it can be used to violate the secrecy of the vote, so it's not actually secure that way either. The only way to make it secure (sort-of) is to not use the insecure device.

> However it requires trust in the officials to do their jobs correctly and to not tamper the tally.

And that is the reason why electronic voting is not an option. Elections have to be able to remove a government from power against its will. An election process that depends on the integrity and honesty of the government that you want to remove from power is inherently broken. An election process that only works when there is no conflict is not a useful election process.
