Police aren't going to follow every automated truck on the road. And a balance has to be found or PDs will ignore shipping companies. Too many false alarms; they stop responding.

So by the time a truck is stopped, realizes a robbery is in progress, contacts command, who assesses if it's a real event, who contact local police, who send a cruiser to check investigate. They thiefs could have gotten away with quite a lot.

Btw, a grand theft rarely rises to immediate action. City PD have bigger concerns, most of the Midwest is sparsely populated. That leaves the bored suburb PD who'll be in the most responsive.
Just because your disk cache is expanding to fill your available RAM (which doesn't even always happen depending on the kernel/RAM size) doesn't mean that extra cache buys you anything. At some point it's just going to be holding stuff that isn't used before it's evicted.
Why just not use a local postgres instead of sqlite, your case seems like overengineering to me.

Yes.

I'm a programmer at a startup that's going very well. The founders have been around the block before so there's no chaos, no struggling with funding, they pay us well, and give us great benefits. There's a lot of care put into organizing project teams (projects usually last 3-6 months) and we get to have a lot of input about what we work on, so that no one person is stuck doing the same thing forever. They don't care when I get to work or how much vacation I take, just that I do the work I need to do.. I pretty get as much autonomy as possible. There's very little expectation to work overtime, except for the very rare crunch time for an important customer.

The projects I'm working on aren't insane technical challenges, but I do basically feel like I'm solving a bunch of little puzzles for a living. There are a lot of nice, capable senior programmers to learn from, so I never feel like I'm stagnating or am in way too far over my head. We've put a lot of thought into our application architectures and the business side is A-OK with us taking time to refactor and tackle tech debt as it accrues.

I can't really think of much I'd improve. Sure, the company doesn't burn money on a crazy nice office like Dropbox with top-tier chefs cooking us scallops and whatnot, but for the stuff that truly matters and makes me feel fulfilled, it's perfect.

I totally hear you about 3. I was super shocked when I (North America educated) went to visit a university bookstore in Bulgaria. For around $5 I was able to buy a "Mathematical methods of physics" book that covered in 300 pages the material that I had learned from three or four books. Sure the book did almost no "hand holding" and just blaster through the material, but still—it was all there.

I've been recently looking at middle school and high school math textbooks and they're even worse than the books for first-year undergraduates. Yes, treat the reader as if they're an idiot and spell everything out and make them practice the steps. It's like the books are written by helicopter authors who insist on showing you their way. No wonder kids are not into math.
It's not 6-dof. This playlist[1] shows VR 180, and the videos are stereoscopic videos with a wide (180ish degree) field of view, but no 6-dof. I don't know if that might change in the future.

They may be marketing pixels "more is better", but they are selling content. Customers come, and remain because of content. Bad content at 4k is still bad content.

It's true good image quality does help, but my point is they already have both simply by specifying the delivery requirement.

What they are doing is more like a company that says they won't buy software that's written on anything other than emacs, or Notepad.
shouldn't the 180 actually be 2 pi steradians? Or is it 2-D VR?

I wonder what % of truck driving is highway driving? If you are covering the trucks in cameras and you have the control software there already it seems pretty easy(relatively at least) to have someone take over via remote for the last mile.

AI sensors combined with some sort of 360 view VR with drivers for the last mile with full AI on highways/freeways would allow for progressive roll out of self driving technology. A lot of video to push down the wire though but probably manageable with modern codecs.
Ask HN: How to get into platform/infrastructure engineering out of college?
Hi HN,

I'm graduating from college next January, and I've been really interested in looking for work in platform or infrastructure engineering, maybe even data infrastructure. I don't have a ton of side projects or any big internships on my resume, but I have a good grasp of Linux plus a handful of languages (Python, Java, C primarily). As for classes I've yet to finish for my BSCS degree, I just have some nontechnical electives and senior thesis.

Any pointers on what technical things I should learn or do next to prepare myself for this kind of work? (e.g. courses, other languages, projects I could try my hand at) I should mention I never took distributed systems or compilers since my school doesn't offer those.
I use a older Macbook Air w/2GB memory as my main home machine, for example.
It's not possible to have a 100% stable currency. At their core currencies are human opinions of how much to exchange for a product or service. But human opinion changes on a whim.

I think a currency could be stabilized by automatically adding coins to the total when people feel they want to hoard them, such as economic panics and reducing them when they feel they want to use it without care such as when the economy is booming.

It has to be automatic but finding a way to do that is the big question. But what and how? Use an index, maybe but it has to be impartial and give a true view of how people feel about the economy at the time.

For the US dollar the Federal Reserve is responsible for increasing and decreasing the money supply but they have truckloads of people telling them how the economy is doing.

A cryptocurrency has potential since in theory you can figure out exactly how people are using them.

Additionally, the supply has to increase as more people use it to create economic goods and services. If you don't, there won't be enough currency to go around and it will limit the potential products/services that people can create and consume.
Sadly true.
Congrats on your round. I'd love to evaluate this for several data initiatives that I'm leading. Signing up.
Major AWS us-east-1 outage
Submitted this a couple hours ago but it was flagged out after a few upvotes?

AWS has been experiencing what many have reported as a complete lambda outage in us-east-1 for hours now. They report "increased error rates" however most reports I have seen from people indicate no invocations are working. We get back a message now from the service saying there is no capacity available. Status page shows many degraded services; presumably they rely on lambda.

Our services are almost entirely lambda based and in us-east-1. Dead in the water. us-east-1 strikes again.

Why? He argues that other people shouldn't get awards, but he's willing to take them himself? Honestly, I don't get it. His stance does real harm to young theorists, especially those doing cross-disciplinary research.

I think Thumbor fits the bill very well. In fact, using something like APSL's thumbor docker image [1], you get the complete setup including the optimizers, object detection, etc. ready to go.

It works really well for UGC as an ondemand optimizer but you can easily make some URL calls to include it in the build time as well.

Yep. I started my skydiving career in California City. We used to skydive into Central Park every 4th of July before the fireworks show. It was an amazing place to learn to skydive, because if you happened to land out (happens a lot with newer jumpers), there were never obstacles - and there was always a road nearby where someone could come to pick you up. Heck, at one point a friend of mine landed so far off the dropzone that the pilot simply touched the plane down on the dirt road, picked him up, and flew him back to the airport.

(We also could use the grid to visually eyeball distance from up top).

The dropzone had been around since the 1960s, when there was a decent amount of activity at the airport (including airshows, balloon rides, pilot training, etc). Like most things in Cal City, it closed ~10 years ago, which did away with another item that lured outsiders into the area. Now, it's pretty much only the off-roading that brings people in.

Definitely a surreal place (but one that is unique and quirky...& has some great memories).
Not that I know of. I suggest it every time the subject comes up of hardening internet connected devices. Nobody has ever replied with an instance of it.

Back in the 80's, most devices used ROMs, PROMs or EPROMS. ROMs were burned at the factory. PROMs could be user programmed once. EPROMs were erasable and reprogrammable, if you put the chip under a UV lamp. As far I can tell, this is a forgotten technology.

Later on came EEPROMS, electrically erasable programmable read only memory. Then someone had the bright (!) idea of connecting the write-enable line to the internet so anybody in the world could update anybody else's firmware, and welcome to the hell we have today.
The Verizon FiOS installer did this in my apartment when I wanted to get cable IP service set up. What should have been a simple self install required a service call to have a tech come out and crawl through the attic to splice the cable back together.
If the Republicans pass this I will be positively surprised.

The DMV I go to is usually slammed, but they have a decent queue system so I only wait about 10 minutes. It used to be a joke that the government was inefficient and companies were bastions of efficiency and customer service. That's how bad the US has gotten. We run a sham economy.
Not necessarily. A physical write-enable switch can work, too. (Not a software switch!)
For sure parents play a big role. The "forced practice" and colaboration with the teachers certainly are factors. I think a socio economic context also plays an important role.

In an affluent family (as define by people who didn't have to worry about money for three generations) access to education is a given, and therefore less valued.

If your family is poor and your access to education is more uncertain, you'd value what you get to learn a lot more. In this context learning and persevering takes on a dimension of "duty" to help out the family. This feeling of duty towards your family caused by family poverty can transfer for several generations. If you grow up aware of the the struggle that your parents and grandparents had to go through to get to where you are now, you end up feeling obliged to learn this math thing.

I think there is just way too much money around. I don't see value in pushing a company to the size of Uber without having an idea how to be sustainable. It would be healthier if startups received less money and would have to be profitable earlier. This is an extremely distorted market.
Here's some more information about Google VR 180: https://blog.google/products/google-vr/world-you-see-it-vr18....

It seems to me that Google has scaled back efforts on 360 video. There are lots of difficulties with 360:

- Large file sizes (hundreds of gigabytes to terabytes of data)

- Inadequate camera quality (even 8k video looks low-quality)

- Bandwidth limitations (in streaming and processing)

- Film-making and making use of all 360 degrees

These problems aren't going to be solved within the next year, so Google decided to go 180 as a stopgap for now.
But they purposefully didn't release the tools or the source code for the tools, despite receiving them.

Incredible. You actually don't belive these women who are out here, in public, risking their reputations, to deliver the truth. This kind of mentality, of not believing women when they report sexual harassment and assault, is what's so fucked up about Tech.

Travis is a shitty human. He has shit morals. He created a culture that discriminated against​ women. He was the leader who was at the helm as Uber grew. Ultimately, he had the authority to change course: he chose not to. That is a massive part of his legacy. It is on par with everything he made at Uber.

Personally, I am glad he got fired and is being made an example. Tech has been an old boy's club for too long. I am sick and tired of dealing with immature, emotionally underdeveloped or emotionally absent, people in tech. One can be a brilliant, analytical, logical, computer nerd AND be emotionally present and responsible. Tech is becoming too important to be held back by childish behavior.

FWIW yes, I am in tech myself. I identify as a man, both gender and sex. I work at a startup in SF.
As others have said, basically it's a problem of control. Normal currencies, in relatively normal times, are semi-managed by central banks. They use tools like reserve requirements and interest rates to influence the rate at which new currency flows into the general economy. It's possible for one bank to trade in the market in a way to peg one currency against another, as China did for some years. And it was costly, because they were doing it while trying to maintain a large trade surplus, so large numbers of dollars were coming in that needed to be neutralized somewhere. It's why they hold so much US debt. Real currencies get in trouble--severe deflation or inflation--when circumstances (the gold standard, external debts financed in another country's currency) make it hard to respond to economic conditions.

This becomes the question: can the system be designed to respond dynamically to demand in a way that mimics the actions of a central bank, without there actually being a central bank? If the goal was to make it so that it was reasonably constant in terms of purchasing power, there's probably a number of metrics one could choose to measure that, but how to achieve it, that's above my pay grade.
Putting it in ROM also makes it unpatchable, meaning it will immediately be infected again when it boots up.

As an EE customer I've been growing quite frustrated over regressions and their EE issues board being basically a black hole where my feature requests/bugs never get responses. There are so many quirks with Gitlab that I can't even think of them all off the top of my head anymore. I used to update it after a couple of days to the latest release (the Omnibus works amazingly) but now I don't even want to touch it when an update comes out for at least a month or two.

It's like they're just steamrolling ahead at 900mph without acknowledging any input from their paying customers.

Global/Group variables, I'm looking at you. Dealing with microservices and Gitlab has been incredibly unpleasant since I can't template out variables.

And come on, this is simple and absolutely horrendous to our UX. It was completely ignored until I sent in a support ticket regarding it. I do appreciate the prompt response once I sent in a ticket, but it just proved to me that it's completely pointless to submit tickets to the EE board. So what, am I better off sending my tickets to the gitlab.com board? What's the workflow here? I genuinely have
no idea. Why isn't there an EE onboarding process and why don't I get support contacts/account managers as an Enterprise customer? In my experience the "Enterprise" issues are what is critical and trickle down into the community releases. That does not appear to be the case with Gitlab.

I know these are growing pains from growing so incredibly fast. I'm not asking for instantaneous results. I'm asking for communication. My ticket sat untouched for something like a month before I sent a support ticket in and it was then tagged as a feature request. Are you eating your own dog food, or am I eating your dog food and spitting out bones bone while paying for a quality meal?

And no, telling me to run sed after the register is not even remotely the fix/response I was expecting. Not 6 months ago and not 10 months ago. I'm trying to improve your software. "Hey, your car doesn't shift into 2nd gear." "That's okay, if you kick the floor 2nd gear will fall into place." "Ok, well your 2nd gear still sucks and I don't want to drive this car anymore."
I don't and will never own a 4K TV, but having seen it at friends' houses I think image quality can go too far. It is so "uncanny" vivid and sharp it's distracting. Maybe because I grew up with NTSC when a 20" TV was a "big" television, but I can't watch the 4K stuff without getting queasy.
At least you got a credit. I've been less lucky.

Hi Dan, Happy Anniversary!

Love your emails, always look forward to reading them in the morning.
> Today, we’re proposing a new framework that allows countries that commit to baseline privacy, human rights, and due process principles to gather evidence more quickly and efficiently.

One interpretation of this is that G will no longer play nice with countries which operate unsanctioned warrantless surveillance (ahem america) and which ban encryption (ahem england) and free speech (europe, depending on your view on RTBF).

If this is a threat it's a subtle one and the end game is a bigger say in the regulatory process.

OK well here's the sort of ops work that serverless kinda absolves you of:

- making sure you don't run out of inodes

- having to manage DB backups

- making sure your cache didn't stop working

- updating your box for security updates (beyond just your application requirements)

It's a tradeoff (architecturally as well), and for a lot of stuff you'll end up wanting full-ish control of your box. But for getting the ball rolling it's nice to not have to first spend a bunch of time getting postgres to start consistently on boot.

You still have to actually manage deploys themselves, of course. And keep an eye on costs, too. But a lot of these services are getting close to "the code that you are running locally, but in the cloud". A far cry from "OK, first lets get apache up, then set up some proxy servers, then set up supervisor" etc etc.
