I did my undergraduate capstone class on the Kessler Syndrome. UNCOPUOS, the United Nations Committee on the Peaceful Uses of Outer Space dictate that a satellite must deorbit itself within 25 years after mission completion.

The Kessler Syndrome right now is a potentially exponential problem that we should be conscientious of because our access to space depends on open orbital lanes.

Heck I think even enforcing local trusted computing effectively is a challenge enough, doing it remotely with attestation sounds like quite a feat.

Does anyone know what the state of executable signing for Linux is these days? I found some unmaintained DigSig project, and some noise about SecureBoot related patches from couple years back. And that would be just a start, I haven't heard anything that would allow enforcing code signing for "dynamic" code (like JS or Python)

You should trace the attackers by tracing back. Work with your upstream providers and mailing lists (NANOG) and publicly shame these attackers. Likely, they are spoofing addresses - validate that and make sure you let the network know where the spoofed traffic is sourcing from to follow BCP38 and BCP84, defined by RFCs 2827 and 3704.

> if you are both capable of programming and motivated by Youtube CPMs please let Patrick buy you dinner and explain how many astoundingly better options there are in life.

Ha. I understand your sentiment, but what you've said is pretty condescending. I would agree that creating content for the sole purpose of making "YouTube money" is silly. I would argue that, to the vast majority of YouTubers, it's simply an enjoyable hobby with RPMs as a potential bonus. The RPMs are intrinsically motivating. There is nothing wrong with being honest with yourself and admitting that they play a factor in the motivation needed to create vs. do something else.

Anyways, my point is, if a capable programmer enjoys making monetized videos on the side, the fact that there are "astoundingly better options in life" is irrelevant.

Yes it is, and we get to use technology from the future this time :-). It is bittersweet for me, the opportunity lost to keep funding NASA at a reasonable level could have a lot of useful data in the 'bank' as it were, but by and large much of the stuff that makes what SpaceX does possible is relatively new. In particular the avionics and MEMs manufacturing has allowed the mass fraction of the operations bits of the rocket to plummet.

I'm still curious though how they got a 30% improvement, and if it was a retelling of the Merlin 1C -> 1D evolution of if this is really a Merlin 1D+. They have also hinted at a project "Raptor" which is a ginormous engine.

And finally it really puts a bad light on "Cost Plus" contracts and the folks at Boeing and ULA who have supplied launch platforms for the last few decades. Clearly nobody in the "old guard" really cared about space, they just wanted to keep the money flowing. I am profoundly glad that they are being shaken up. Perhaps some of the management there will actually listen to what the engineers have been proposing for years and years.

All true. The first used F9 payloads will likely be Geosynchronous communications satellites, where the smaller payload is mostly fuel for apogee kick and station keeping, and the rest is mostly off the shelf hardware.

Alternately, operators of large constellations, eg. Iridium that can replace the payload relatively quickly and cheaply. Opportunity cost can be mitigated if some of the payload is intended as on-orbit spares.

Looks like an interesting project.

The license or terms-of-use seem weird: "Picat can be used for any fair purpose, including commercial applications. The C source code is available to registered developers and users free of charge. The project is open to anybody and you are welcome to join, as a developer, a sponsor, a user, or a reviewer. Please contact picat@picat-lang.org"

Why make things complicated with these conditions? If you are going to allow source access, why not use a standard open source license. If you aren't, if you want to control of the language for some purpose, make it clear this is a commercial product.

The GPL (and other standard open source licenses) are a real commercial licenses at this point. Roll-your-own software licenses seem a lot like roll-your-own device device drivers - might have made sense in yesterday's world but not today.

I'm surprised to hear that this is a problem for the Navy, because it certainly wasn't a problem in the Marine Corps (a department of the Navy). Table top exercises were pushed all the way down to the lowest level in the infantry, with force on force exercises occurring at the company level. It was a common sight in the field, between exercises, to see squads huddled around dirt terrain models - gaming out scenarios with the squad leader acting as dungeon master. Some interesting ideas came out of those sessions, like prehooking tow straps on humvees and top down building clearing. A few times a year there would be battalion level exercises, where the officers got to play, but the enlisted were always running scenarios.

The lack of officer war gaming might explain why casualty projections for urban combat where so insanely high, stale information plugged into models that no longer fit reality.
No.

Anecdotal argument:

In my budget the biggest costs are housing, food, utility bills.

The costs of my semi-automatic robots - such as the dishwasher, fridge, washing machine, vacuum cleaner, lawnmower are loose change in comparison.

I doubt the fully automatic robots of the future will be excessively priced but yes some patent holders will be rich, even undeservedly so, but we won't be their slaves.

The bigger problem with robots is something similar to The Matrix movie. A side effects of a very smart robot is that she becomes aware that there is more to life than serving humans.
Are executives god-men? Probably not, but I suspect, as is often the case, the job seems a lot easier than it actually is.

I find engineering types are especially prone to underestimating the difficulty of other jobs, and we have very little context to evaluate executives who have very little overlap with engineering.
It's hard to see when there is so much money in the way.
I don't think they have to overlap just because you defined them rationally. I think it just becomes painful to address pixels if you don't have them overlap. I'm not certain on this point, however.

But it's painful to use an infinite string as an address too.
So yeah, it's possible to build a kernel that provides

Not without a cost, though.

Software engineering is all about tradeoffs and making the right ones, I feel the Linux kernel community has made the wrong one by forcing those costs onto users instead of helping absorb some of that themselves.

I never said it was free or that there wasn't a cost; I just said that usability is important and have implied the Linux kernel developers should care more than they do now.

Decouple the application from the DB. Use a DB as a service that has an HTTP API. The application encrypts/decrypts all data with public/private key pair. The user, your client generates their own key pair.

This is the scenario we are testing out with http://schemafreedb.com/

You do not have the private key so you cannot see the data but you still can offer the data portion as a service. Your client does need to host the application depending on your target client node may be a good choice or if you want to go mainstream go with something like php.

When ever you have update to the code you can provide a diff of the changes.

You'll also notice that exactly none of the problems fixed in this advisory have any tests, either to check for regressions or for similar problems elsewhere. This is just negligent.
It's not clear from the article that that's a smoking gun. Just prior to that point, we see:

"Elevated levels of radon and carbon monoxide were detected but later ruled out as a cause.", with a link to a Russian page that, Google Translated, seems to actually indicate that CO is still a leading suspect. However, the article immediately goes on to apparently quote from the same Russian page that

"...some of houses (sic) of the affected residents had carbon monoxide levels that were ten times higher than recommended. This... could have caused similar symptoms to the “sleeping sickness”."

So the article itself seems a little sloppy. Beyond that, I wonder what the sickness relationship is between high-CO houses and all inhabitants of them, given that at least one inhabitant per house has experienced the sickness. Is there a correlation? Also, is the social structure of the village such that there are frequent visitations to most or every home? If so, then one might expect to experience the sickness even if one's own house doesn't have high CO.
Pretty much any web stack will allow you to disable sessions. Not sure why you think you need something special.
There's no point in trying to verify that your app is running the server-side code it claims to be running. That still doesn't prevent you from logging into your own server as root and taking everyone's data. If you have people's data unencrypted on your server, they are ultimately trusting you with it, not your app. Part of that is trusting your app not to have a security hole that leaks data to third parties, and verification could help with that. But it won't help with securing user data against a malicious sysadmin.

What you're describing is (or used to be) called fax-blast car buying [1], and the best move once you've firmed your decision on exactly what you want is to contact the fleet sales managers with either a quote request, or an offer to buy - repeating the offer process until you stabilize on a overall discounted price.

In my case, I worked with 3 dealerships (one where I test drove the vehicle and 2 other fleet managers. I ended up going with the original dealer because I had more rapport, he was flexible on pricing and agreed to complete the paperwork and hand over the keys at our house (we had newborns) - I had no idea this was even possible, and was a nice completion to the purchase experience.

There are areas where it's reasonable to ask people to call. Where it gets suspicious and tricky is when some businesses state prices up-front, and others ask you to call. When the nature of the thing requires contact, they'll (almost?) all say you should call. For example, plumbers typically won't advertised fixed rates for jobs, and in the rare cases they do that's a warning sign.
This may have worked where you live, but all the dealerships here are refusing to play that game.

They'll all give you a form letter "come in and talk with us" message. Apparently cost-plus isn't that appealing to them, and they'd rather lose the sale and wait for a higher-margin purchaser.
That's an optimistic view. My take on it is "market share|revenue > human rights".

Assessment needs to become more accurate and more of our taxation should shift to land, and away from productive activity.

It may even be possible in many locales to use self-assessment, with the concept being that if you set it too low, others may outbid you according to a certain set of rules to keep things fair and reasonable.

Current property tax assessors are licensed professionals, and each county in the US handles it differently. Sometimes they are elected, sometimes they are appointed.

One could also imagine the local governments outsourcing assessment to private tax assessment companies. Zillow and many companies already have assessments for most of the country freely available on their website.

So, my issue with CMake is that I usually run into it with annoying academic projects, or other weird shit--that doesn't matter, but what does matter is that the code quality tends to correlate pretty well with my personal rage.

When I try to run it on Linux, sometimes it'll just fail because reasons (looking at you, player-stage five years ago). When I try to run it on Windows, I have to fiddle with settings, rerun it a few times, and only grudgingly will it emit a project and directory for me.

And what it does emit? Almost never a properly organized project. Usually a project with a name like "Project1" and some rando layout. Usually I can't even figure out what #defines are being set, because it's hidden away.

I'd much rather people just write simple Makefiles (it can be done!), and a few VS project files, and be done with it. CMake has never once, in the last five years, ever resulted in me looking up from my machine going "Man, that was such a good experience, I'm sure glad we have CMake!".

This is the general case. Wish more people thought humbly about other positions besides theirs.
Well. If the average size of firms has gone up so has market concentration. Market concentration brings market power, market power brings arrangements that favor those who hold that power.

In general, markets with low concentration are defined by competition while markets with high concentration are defined by power. For measures of concentration see the HHI or the concentration ratios.

> There's a popular idea that businesses (and people) have no responsibilities to anyone but themselves.

A company could easily make a statement to its investors about its moral stance on issues that it expects might harm the bottom line.

The company does have responsibility to its investors not to go rogue and burn cash just because it feels good. Most of the time the kind of corporate behavior that you praise is actually clever PR that costs the companies little.
