> I took the train once from Irvine to Los Angeles and felt I had gone back in time to 1980. This in one of the richest counties in the world (OC)

Have you considered that richness is not measured correctly? Since GDP is effectively consumption, the more a person consumes, the richer a country is. A thousand people driving 5 hours between LA and SF will make the country richer. Not the people, which China appears to be wanting to do.
They must spend way too much time on HN or reddit, because out there, most people don't care whatsoever about these sort of issues. It's only on these boards that privacy is a hot button issue.

Ask HN: Starting a Class Action Lawsuit?
Hello HN,

I'm a student at Purdue University, and I believe I have a very clear case against a towing company regarding illegal towing practices. I've contacted 2 attorneys, both who said I definitely have a case but need to do more research before going further, but didn't quote a specific $ figure if I requested their services.

How should I go about this process? Have you ever been involved with a class action lawsuit? This class action would affect anyone who has been towed by this company, but I have no idea how many students/people that would be. The company was founded 18 years ago, but I wouldn't know how long they've been not following the Indiana Code. If the community has any advice, this has been a very legal, confusing process so far.
It seems to me this encouragement of partial attention while driving just doesn't work for human reasons. The more you give people an excuse not to participate the more they will withdraw and blame technology when something goes wrong. You're either driving or you're not - there is no middle ground.

> I've rarely seen vendors sharing e-mails with payment and shipping companies

If it was done correctly, odds are good you wouldn't even know those emails originated from a third party vendor. Plenty off stuff you order is fulfilled by third party vendors who specialize in payment & logistics.

For example, if you ever ordered contact lenses from costco, the whole damn thing is driven from vendor called "WVA"[0]. I'm pretty sure it is completely turn-key. Only way I figured out what was going on was looking at the return address in streetview.

I ordered a lockpicking from an online vendor and it was fulfilled by some logistics provider on the east coast. Same kind of thing...

So I'm not actually sure what your problem is, but plenty of businesses have a need to share your contact information with their vendors.

> The value you plugged in was a year of energy consumption. Why not a day, or a century?

...because when I pulled the number from wikipedia it said it was the energy consumption for a year, not for a day or a century.

> You're not using the equations incorrectly, but they're not telling you what you think they are.

> They are telling you - if we store up all the power use of humanity for this length of time, then use it to blow the air, how fast will it go.

...no, it's telling me if we collect the energy used by humanity during this length of time, then use it to blow the air, how fast will it go. You cannot use "energy" and "power" as if they were interchangeable, they are not.

What you may be missing is that these physics equations go both directions. If we take the blowing of the air and use it to produce the energy used by humanity during this length of time, we'd expect to see the same decrease in speed.
Have the courage to stand up for what you believe in, even if it terminates your employment status. I'm only unkeen to have my name on this, because I haven't done it, and I wish several times in the past, I had. I respect the person who did this early in his career in one ISP immensely: it was stunning to watch somebody say "you're full of shit" to the new CEO, and walk out. (he was btw, full of shit)
Does that mean I can get one of those new surface laptops and run linux on it? IIRC the first gen version had some issues with the keyboard.
Another factor is increased number of trucks and SUVs. Pedestrians are struck higher in their body and are less likely to slide off the hood, but are instead underneath the vehicle.
Is the implication that the purpose of the door desk was to merely APPEAR frugal? Or did it have some other original purpose entirely? I still didn't quite get that part.

Every position is absolute. Either you have 100% user privacy, or you 100% don't have user privacy. People pretend that the latter option can potentially include "checks and balances" and whatnot, but Snowden showed us how that plays out in reality...
After reading that, I looked up someone on LinkedIn who we (my employer) fired who I worked closely with.

Yup, he did that.

In such a situation I'd just omit some of the short stints from my resume, and then when questioned, I'd be honest. Say something like, "I had a rough period where I really hopped around. In my opinion, listing every short stint on my resume would make it too hard to read."
Ah, well still a bit more tedious as far as I can see, but better than nothing. Thanks!
Steampunk was most assuredly not born out of the 1999 movie. If some ridiculous movie tainted your view of the genre, I think that's more a reflection of you than the genre or the terrible movie.

That said, the movie was supposedly inspired by a series from the 1960s by a nearly identical name ("The Wild Wild West".) The genre, however, has been around for much longer, and the name 'steampunk' seems to have its creation in the 1980s.
so this depends on the database engine and while in general it may follow a pattern there are no guarantees.

so, SQL is not about how you're going to get the results it's about what results you want.
True, but those caveats apply to OP's technique too. What I am saying is that there is no specific behavior of a tmpfs which causes things in it to be necessarily persisted to disk like the parent was suggesting. It works just like any other anonymous memory does.
I think the thing you are going to build is already available on GitHub for free.
I agree with your sentiments overall, so don't take my "it's not all gloom and doom" comment as a disagreement... But there are people out there trying! The project from Texas Central Railways is looking like a sooner bet than California's line, for a number of reasons. An example of a reason is lower price, stemming from geography. The route doesn't require building tunnels through mountains and the like.

Although even then there are some disappointing Catch-22 processes at work. A State Senator is using the existence of a particular court case to try and delay/prevent funding, and the plaintiffs of a court case using the Senator's opposition (which cites their case) as an argument in favor of their case.

Nonetheless, I'm optimistic on the Dallas to Houston high speed rail. In my dreams, I see that project's completion as giving California a dose of motivation, so as not to be second fiddle to Texas.
> Jerry Brown tried to build the CA bullet train 4 decades ago.

Amusing to me he did the Rip Van Winkle and popped up as Governor again after 30 years. In office he pushed hard to get CHSR built. Every time California's high speed rails come up on HN it's obvious that everyone here hates the idea. So the US is getting what it's collectively asking for and deserves here.
Good point, happened I had one today that appeared impossible, yet (of course) it was easily understandable once the root cause was found.

Concerning the database optimizer:

is it only my (wrong) subjective feeling, or did the one of Oracle become much more stubborn about following "hints"? https://en.wikipedia.org/wiki/Hint_(SQL)

Reason: I started dealing with Oracle when it was at v8 and I think up to including v9 when I specified a hint it was usually followed. Then later with v10 and v11 it progressively became more difficult and nowadays with v12 I'm having a really hard time (I usually have to use some "tricks" that don't change the logic of the SQL but do change its technical execution, like placing somewhere a useless but tactical "distinct", to confuse it enough so that my hints are more or less followed/used).

Btw., if you want to state something like "using hints is wrong" then in general I agree (with some exceptions for special cases) but currently I'm taking care of a very old app that uses often quite big SQLs (involving up to ~15 tables) and as the maintenance budget is limited and the app will anyway be decommissioned in 1-2 years I cannot start rewriting half of the application to break down and improve the statements => when once per quarter the data distribution/quantity/etc... change and the optimizer thinks that it has a new brilliant idea about how to exec some SQL and then of course the SQL hangs then I usually just try to spend 1-2 hours trying to find some hint(s) that will bring back the old execution plan, but since we upgraded to Oracle12 I often see no change in the exec plan unless I do what I mentioned above.

What is the value (to Apple) in providing this kind of detail in maps, other than aesthetics? I'm trying to understand why Apple (or any company) would invest money into what seems like a marginal improvement in UX. The city landscape is constantly changing, so there's associated maintainence cost too.
The great news is that tooling is rapidly improving these days. VSCode with the new ghcide is simply amazing. Ghcide is still new and thus has a few rough edges (eg. TH) but overall it lifts the Haskell IDE experience into the 21st century. Give it a try.
One of the new safety standards in recent years has been a mandatory space in between the hood and anything hard like the enine, which is intended to act as a crumble zone for pedestrians. This has caused auto manufacturers to raise the hood above the chassis to provide this distance. This makes the beltline of the car taller, which with the roof unmoved results in a skinnier greenhouse. A skinnier greenhouse now means there is less driver visibility as windows aren't as tall.

Another increase in safety standard in recent years has been advances in rollover protection. Auto manufacturers implement these protections by reinforcing the columns leading to the cars roofs. These reinforcements add thickness and mass to these pillars, especially around the C pillar. These thicker columns take up more room in the greenhouse's corners, which now mean drivers now have less visibility into the critical blindspots of the car's rear. The reinforcement also are heavy, which decreases a car's ability to execute evasive maneuvers due to an increase in inertia.

A third increase in safety culture was the expansion of air bags to more portions of the interior, which allows protection in additional collision directions. These new airbags are mounted on the roof and pillars of the car. The mass of these airbags decrease available space in the greenhouse of the car, which decreases driver visibility. The mechanisms for these airbags are also heavy, which decreases a car's ability to execute evasive and braking maneuvers.

One easy way to combat an undersized greenhouse in a car is to make the entire car bigger. This can enhance the feeling of safety of its users and improve aesthetic proportions. A bigger car is also a heavier car, which results in a decrease in maneuverability, braking, and fuel economy while also causing an increase in collision energy.

The conclusion of all this in that our pursuit of safety we may have actually increased the risk of getting into accidents overall
No, it is pretty random, just as the orbits of binary stars are randomly oriented. The scales of star and solar-system formation are much, much smaller than the scale of the galaxy, so the memory of the latter has been scrambled by all the intermediate and local processes.

From this Cornell "Ask an Astronomer" page (http://curious.astro.cornell.edu/about-us/159-our-solar-syst...)

"The size of a solar system is so much smaller than the size of the Galaxy, that the Galaxy's structure has no impact on the orientation of a solar system. What determines their orientations is the direction of the angular momentum that the system had when it formed, and that's pretty much random."

Or take a look at these ALMA images of protoplanetary disks (solar systems in the making) around pre-main-sequence stars. All are at very similar distances, and most are at very similar positions relative to the Galactic plane, so they should all show very similar projected shapes and orientations if they followed the galaxy's orientation -- but they are all over the place.

I am sorry that you somehow think this has become a Haskell vs Clojure fight. Me, I actually use Haskell a lot more than I use Clojure, and generally think it's a great language with a lot to offer.

But I also believe another very important thing: There is no silver bullet.

Because I believe that, I am able to recognize that even the things I love have some limitations. And I don't believe that this should be a fight, and that is why I think I should be able to articulate what I have found to be the limitations of a tool, and acknowledge that some other tool that other people like might have something to offer in this area. Without being perceived as a hater for doing so.
I never really understood how these desks were "frugal". I looked into doing something similar in early 2005 after hearing stories about these, but solid-core doors were more expensive than the other options. I ended up buying two two-drawer filing cabinets (because I needed storage space anyway), running two 2x4s between them, and laying two 2'x4' sheets of MDF on top. All the parts, including the filing cabinets, cost less than a solid-core door alone.
Hindsight is 20/20. It’s all about what the right decision was with the information available to you at the time, not what decision would’ve had the best outcome in retrospect.
Could be something as complex as MS Project or simple as a shared spreadsheet with rows for each project and columns for each milestone or for things like ETA, dependencies we’re blocked on, escalations needed, scope changes, etc. Not sure how that could gel well with a source control tool but I’m all ears!

I think 1/4 of the challenge is what tool to use and 3/4 is convincing and motivating people to be reliable and forthcoming with accurate information. A good project manager demonstrates he or she can add value, unblock things, escalate and communicate appropriately, and not just be the Project Police.
Totally agree. Waze is increasingly awful and ineffective as more people use it.

My block ended up being selected as a detour around an intersection that gets gummed up by a poorly programmed traffic light. After a few near misses, a couple of the neighbors got together to basically double park with blinkers on in such a way that the traffic slows down.

In light of all the Epstein stuff, it sure sounds like "were raping children, so don't implement end to end encryption, or someone might rape your children." I'd say it's ballsy, but with how publicly they executed Epstein right under our noses, it seems like they just don't face punishment for breaking the rules and want to rub it in our faces. It's not like any of us would get away with that. Fucking pathetic. The best anyone will do is tug on their leash a bit. Back to the treadmill, and pump out money for your masters you fucking sheep.
What purpose does distributing information on explosives provide other than creating knowledge of how to create explosives something which most people don't have an actual need to know how to do, regardless of how trivially way it is to do. Someone the next town over destroyed an entire condo complex killing himself making improvised explosives.

I agree, myself knowing how simple it is to make IEDs from home devices (I was in the military and defusing IEDs, mines, etc was part of my MOS), that the line between explosives and propellent is tenuously thin if at all present. The issue is the intent of dissemination of the information. What possible reason other than making devices that could put people at risk provide to the public? He was intentionally putting out information to attempt to cause harm to other individuals and the right to life is primary before the right to liberty in the Constitution. A bomb is not a self defense tool like a firearm. It's not useful for controlled demolitions. It's sole purpose is to cause fear and harm to others. That's why it doesn't fall under protected speech.

It's getting harder than ever to see out of modern "safer" cars, too. I regularly entirely lose cars hidden by the B-pillar on my Model 3. I have to rock my head back and forth before each lane change to make sure something's not hidden there. It's compounded by the fact that the driver's side mirror doesn't physically move far enough to the left to cover the blind spot like it would in most cars, and our terrible flat mirrors in the US don't provide the wide angle that european driver's side mirrors have. (still working on sourcing a european mirror glass; currently Tesla only sells the entire mirror body+motors+glass as a single part, for $400ish)

It's VERY easy to lose a pedestrian in the A-pillar (windshield pillar) of modern cars, particularly due to how large these units have gotten to accommodate side curtain airbags.

Note that the fixtures on the body don't have to 100% optically obscure things for them to be 'invisible' to the driver.

>It gets even worse. Not only can we not see though solid objects; research has shown that we tend not to look near to the edges of a framed scene. In plain language, we tend not to look at the edges of a windscreen. So, not only do the door pillars of a car represent a physical blind spot, but our eyes tend not to fixate near to it, leading to an even bigger jump, or saccade, past a door pillar. This is called windscreen zoning.
I think a huge part of the problem is that car companies aren't properly incentivized to protect pedestrians. It's easier and cheaper to prevent my car from hitting something that can damage it than to prevent my car from hitting something that it can damage (easier to detect buildings and other cars than to detect children). If you were the CEO of a car company and had a finite amount of money to spend on research on driver assist features would you rather spend it on the easy problem of protecting your customers or the expensive problem of protecting other people? Furthermore, as a consumer, would you rather buy a car that costs x dollars that protects you or costs x+y that protects other people?

I read this back when it came out. It's an awesome detective story. The central question is why would someone perpetrate such a minor fraud. It is like art forgery but you can't sell it.

You have to get into the fraudster's head, which the article does to a degree. The resulting answer isn't rational in the sense that you would agree with. The fraudster doesn't get anything but rather damages something. You come to an empirical understanding, according to the facts presented, of a minor mediocrity passed over by life and striking back.
This looks much better than the way it is done in C#.

I absolutely hate the SQL-ish LINQ expressions in C# code. It's really awkward when you make a query and need to materialize it. You either store the Queryable<> in a temporary variable and then convert it to a list or an array or whatever, or you have to glom parentheses around a big LINQ expression.
She’s pretty clear that she means the order things happen semantically. Just like in any programming languages we talk of things happening in some order, but under the ”as if” rule the compiler and processor can reorder things however they want.
hah. famous last words. SQL is beautiful. I allows non-developers to actually work with data in ways more flexible and extensible that most notations/languages out there.
Which you probably shouldnt, because you are just writing the subquery each time - a temp table in MSSQL is a much better solution than CTEs 99/100 times.
