Perhaps it's because you were trying to shut down discussion on the technical/communication aspects of this disaster for no reason other than it was a tragedy?

That would be an entirely appropriate topic of discussion.
There are developments towards approaches that put less emphasis on the negative thoughts and which are more in line with mindfulness. From what I've read, they're at least as effective as CBT, and might well be more effective for people who already ruminate too much (autism, for one). But AFAIK it's too new a 'field' to be too confident about these things. Worth looking into though.

As a fan of zen/mindfulness and as I'm going through CBT currently, I definitely feel some friction between the two approaches.
> One major limitation of malloc (and even the best implementations like jemalloc and dlmalloc) is that they try to use a single allocator for each data structure. This is a mistake: A huge performance gain can be had by using a separate allocator for each of your data structures — or rather, for each of your data usage patterns.

I stopped reading the article at this point. This statement has been disproven repeatedly over the years with Hoard and jemalloc. It is counter-intuitive but the data backs it up.

Custom per-data-structure allocators can fragment the global memory arena and cause more CPU cache misses as result of the extra code involved. The latest/greatest malloc/free implementations use a myriad of optimizations to achieve speed improvements that a custom allocator implementation would rarely use.

It's not an accident that jemalloc is so widely used in major applications - it works extremely well.

I work in an MVVM mode daily. The best MVVM frameworks help bootstrap the app shell, but require zero interfacing with the view afterwards, with the 'controller' just being a parent ViewModel. It's turtles all the way down.
I also remember something like this. I just checked, this is a old idea, there is a patent (US 3507348 A) from 1970

They were beasts. I left mine at my parent's house, and was hoping to reclaim it, but my cousin John had borrowed it and sold it years later. I should have kept tabs on it!

When I look at the video of Kalman Reti running Symbolics Lisp Machine in an emulator [1], I am still blown away by how much more sophisticated and aesthetically pleasing it was compared to my PET or the Apple ii. The difference seems almost asynchronous, like time-traveler tech.

How you could just drop in to any system library, or even the kernel, and use the same language, Lisp, to modify anything live is astounding. A lot of people have dismissed any talk of how great LISP Machines were as a bunch of nostalgia, but I don't think any of them have watched 15 minutes of somebody operating in that environment. You can't look at it, and keep a straight face when talking about how great the Apple ii was or the Lisa for that matter later on.
I have at least eight cards of unknown value from different times I've been to Atlanta, and had to leave the airport on the train, which requires you to buy a transit card. Somehow I never remember this is a thing.

> for the government to swallow their pride, along with the evidence presented to them, and change the law

As another poster has already quipped, there's practically zero chance of that happening without overhauling the entire government. It may be hard for us, makers and engineers, to see why anyone would obstinately refuse to accept facts as ever more data flows in, but that's not how real life works. Sadly.

Politics and engineering are, in certain aspects, polar opposites. In politics changing one's opinion, even in face of facts, is a mark of incompetence. That's a big factor in why it takes so long to reverse bad decisions. While enough (read: too many) of the representatives who voted 'yay' are still in office, they will keep attacking any attempts to undo whatever they have done or approved. And because the big decision was to make all drugs illegal, there will be constant squeeze to push all other decisions further in that direction.

Reversing the earlier error is simply inconceivable. It takes a new generation of elected representatives to revoke old laws.
Yep, if obesity and T2 diabetes and alcoholism are public health problems due to dietary misbehavior, then drug abuse is too, and for the same reasons.

League of Urban Voters: we would work together to draw up a workable plan for the next 12 election cycles (or so) - the LUV would accept members and donations from all who support the goal of increasing density and urbanization. Key congress people supporting the goals would be identified, along with professional city planners and professionals at universities. Supporting cast members would be industry groups and other coalitions that we find common cause with. We would collaborate with them to develop talking points and in-depth policy wonk analyses, policies, and plans.

After we had hammered out the key policy points and major reasons to shut down the pro-single-occupancy house policies & pro-suburb policies, we'd go onto the campaign path, understanding that it'd be a 48-60 year battle. There'd be a blog, a forum, probably eventually a think tank and a journal. Given a careful orchestration over the timespan of two generations, a reasonable success would be had.

There's no God-given right to live in your own home on an acre of land in the US. Or in a 120-story skyscraper. These capabilities are hammered out through politics, engineering, and money. If the sociopolitical scene is tuned to have cheap houses, it'll have cheap houses. If it's tuned for condos in skyscrapers, it'll be condos in skyscrapers. This genuinely is malleable stuff here.

N.b., this is not unique to housing policy. You can define the same general game plan for any particular issue you like.
Hi Jacques! One thing I can't wrap my head around: how do you compare candidates when you have them working on different projects? How do you protect against Candidate A finding themselves pairing on a relatively easier project than Candidate B? How do you deal with pairing on things that are complex and require time to spin up to understand the system architecture, the code base, and the problem at hand? If you only expose smaller problems to candidates, how do you ensure that on any given day there will be an appropriate problem to pair with a candidate? Thanks!
Huh? 99% of domains point to some nameserver they aren't contracting service? That is, 99% have invalid NS?

I think it's been working for a long time, I just ran

My point is that research or even exploitation is not causation of security flaws.

The flaws themselves are what make people insecure and ignoring that by complaining about people researching them for whatever reason suggests that we should ignore security flaws and just blame anyone who looks.

The release of the concentrated archive will help security in the long term the same way that a fire that burns down a city improves fire safety in the long term by encouraging changes to building codes. Ideally, such things should have been done already, but people tend to only fix things after something catastrophic happens.

Hopefully, people will realize that they need to adopt solutions that are more resilient. That means equipment running fully open source solutions such as PFSense, OpenBSD, LEDE, etcetera.
How soon is soon? 5 years isn't going to happen, but 15-20 is quite possible the way things are going right now.
Surely arduino's these day would make that pretty simple
I believe that is different. IIRC, that theory was about shooting ionizing radiation in front of the vehicle to reduce air density.

This is using tiny, precise plasma "fans" plus a lot of computational fluid dynamics to direct the airflow on a small scale. And it's not a very bad idea.
Instead of forbidding burkinis, a better way to fight against this backward repressive fashion would be to encourage people to go swimming in the nude.

I don't think so. This at best confirms there is a power-law distribution in the oil sector. The change is still "move our civilization off of oil products" because it isn't just these companies producing emissions but all their customers too, which isn't particularly "new" news.
The thing is that these are not equivalent hello worlds. I mean, if only for the fact that the cmake example does proper header dependency management, which is essential to correctly compiling c/c++ code as it changes. It's not something you can leave out of a makefile and still call it correct.

Common Lisp (packages and symbols are first class). There are some gotchas at first but then they feel quite natural. You write your code in one place and manage visibility elsewhere.

This allows for example to make a symbol exported in different packages, or take separate code and provide a unified facade package. But most of the time you just need to define the public interface of your code and this is quite easy.
>> It's surprising that even with the energy it takes to generate a plasma strong enough and in enough quantity to achieve the desired effects, it can still result in an estimated 25% energy savings. It goes to show how much energy just deals with drag in the current system.

You've made an assumption that they are taking the energy required to create the plasma into account in their aerodynamic efficiency calculations. I didn't see any indication of the power required to produce the plasma, much less that number of power already required to fly. I did see the suggestion of using it on electric planes or wind turbines where larger amounts of electric power are readily available - one can interpret that availability as a convenience (high voltages and power are already there meaning less complexity) or an oversight (we're just neglecting the energy required). Nowhere in the article is this directly addressed. It would not surprise me if the truth were somewhere in between - it takes a lot of power, but saves even more.

I've seen a similar situation in the hybrid car world when making certain comparisons.
Initially we were using an hosted CI (which I won't name), but it had tons of problems we couldn't fix, and we were against the wall in term of performance.

To put it simply when you run a distributed CI your performance is:

setup_time + (test_run_time / parallelism)

So when you have a very large test suite, you can speedup the `test_run_time` part by increasing the parallelism, but the `setup_time` is a fixed cost you can't parallelize.

By setup_time I mean installing dependencies, preparing the DB schema and similar things. On our old hosted CI, we would easily end up with jobs spending 6 or 7 minutes setting up, and then 8 or 9 minutes actually running tests.

Now with our own system, we are able to build and push a docker image with the entirety of the CI environment in under 2 minutes, then all the jobs can pull and boot the docker image in 10-30 seconds and start running tests. So we were both able to make the setup faster, and to centralize it, so that our workers can actually spend their time running test and not pointlessly installing the same packages over and over again.

In the end for pretty much the same price we made our CI 2 to 3 times faster (there is a lot of variance) than the hosted one we were using before.

But all this is for our biggest applications, our small ones still use an hosted CI for now as it's much lower on maintenance for us, and I wouldn't recommend anyone going through this unless CI speed becomes a bottleneck for your organization.

That's a supposition made on very small evidence. They offered him employment with shares - one interpretation of the ambiguous offer. To suppose they meant anything more is pure conjecture.
Definitely not true. There were plenty of producers who were "involved in selecting the musicians who play together, what songs they record, how they're arranged, mixed, sometimes even contributing to the writing, etc." -- Orrin Keepnews, Teo Macero, Alfred Lion, Creed Taylor, Ozzie Cadena, Don Schlitten, and the list goes on and on. A good producer often made the difference between an OK session and a great one (case in point, Sonny Stitt).
Both the Docker blog post and the Gartner piece seem to be silent on the topic of out of date and vulnerable software in Docker images, which has been much talked about.

Looks like Docker have put out a content scanner service to mitigate the problem this still seems to be a weakness relative to the pre-Docker way of building VMs.
Very true. And, of course, it is important to remember that interviews are in many ways two-way streets: the candidate interviews the company just as the company interviews the candidate.

Out of curiosity, how do other languages cope with:

a. Targeting different release types (debug vs release)

b. Changing behaviour of the compiler

c. Having different code paths between debug and release (#ifdef _DEBUG)

d. Having macros and helpful macro expansion

I do not understand the dislike of header files: how would you recommend distributing DLLs and libs while exposing their functions to be developed against?

I suppose you could implement everything in a header file if you wanted a simple "module" system (thinking of the header as a module), but this would establish a very simple system with no interdependencies or reusability.

Besides cost cutting via layoffs being a favored (although by no means the only) strategy for PE firms, there's also debt servicing.

Typically, PE companies buy the company while only putting down a small portion of the purchasing price. They finance the rest through banks. The whole concept is pretty similar to buying a house with a mortgage, except you're buying a company. The debt payments are then a tax write-off, and all/most available company cashflow is diverted to paying off that loan. The ideal company is one with reliable cashflows and access to a growing market (of which I'd say a large cloud infrastructure provider fits the profile).

To improve cashflow: pay fewer people less, convert assets to cash, and/or make more money from your core business. Usually a mix of the three.

From an organizational standpoint, you can think of it like Rackspace just took out a very large (maybe subprime) mortgage on the company and some new people are going to try to make sure that doesn't turn out to be a horrible bet, first for the investors, then for the company.

And as a reality check, Juno's total budget is on the order of $10^9 over six years. So roughly $200 million per year, or about one percent of Nasa's yearly budget, which itself is a bit over one percent of the US federal discretionary budget (about a 1/300th of the total budget).
"The federal government now only has tax deductions for condos and renting in areas where the occupancy is > 10 adults/acre. Increasing deductions are possible through increasing the adult/acre density".

The Equal Housing authority will be auditing all sales and rentals of single housing homes; landlord violators will be fined severely; mortgage lenders who violate will be fined severely".

Also, with the demographic shifts in the US and how they affect urban areas, it's absolutely relevant to the nation's commerce.

It's not the same. Strangely the docker-swarm tutorial doesn't mention swarm mode. I wasn't able to follow it successfully with Docker 1.12. That was when I realized docker-swarm != swarm mode, so I tried the swarm mode tutorial instead, and it worked as expected.

Maybe docker-swarm is not supported anymore with 1.12? It was all pretty confusing.
