It's just poured concrete. Building house shells from poured concrete is done worldwide. Edison started that; his system for low-cost housing used standard forms that locked together. Then you pour in concrete, wait, remove the forms, and you have a house. He even built in concrete furniture, which wasn't popular.

Much of the world lives in poured-concrete apartment blocks. It's just so cheap. The main problem is crap concrete mixes. If you want to improve concrete construction, come up with a hand-held device where you stick a probe into the mix and it tells you if it's OK.

This has been tried a few times.[1][2] Just pouring on concrete like that doesn't compact it properly. Compare the Lil Bubba curb making machine, a simple machine which makes concrete curbs.[3] It's a slip-form machine; the form gives the concrete a smooth edge and top, and as someone shovels in more concrete, it compacts it and pushes itself along. The 3D concrete printing people need to develop something as good as the Lil Bubba. Then they can make flat, solid walls in place. Some of the competing machines have some slip-form guides, so they get a flat surface.

Do people on here agree with this? I think that is far too cynical... education (even this guy's education) tends to be misaligned from a person's actual interests, and so most would rather not do it in their free time. But I do think people want to do work/productive things and not just watch Netflix.

Sooner or later the 3 major addictive components that the food industry uses to grab customers need to be regulated: sugar, fat and salt.

Without regulation it results in an arms race, a new brand comes along and how do they grab customers? More salt, more fat and more sugar than the established brands.

For any progress to be made, there should a tax on these big 3 at once and not going after one product at a time.
Indeed.. Social media users don't get those tools because they are not the customers, they are the product.

>Make has a fragile syntax that barely works for simple filenames

It works perfectly fine with things other than space.

>and it has a host of cryptic functions with difficult to understand semantics

This is why the GNU Make has a fantastic manual, I suggest you check it out: https://gnu.org/s/make/manual

>That it's what is installed on most Unix-style computers isn't an argument against trying to make different/better systems.

You aren't making a better system though. You're making a worse, less flexible, less understood, system that no one can hire person to work for and that won't be useful at any workplace. If you really wanted to improve over make you'd be making a general purpose tool that isn't targeting any specific project or language.

Alas, this has jack shit to do with the comment you're replying to. Let's deal with the issues we've been talking about before shifting the goalpost.

>Also, you can set SHELL to another scripting language, but that defeats much of the point of using make in the first place.

It still gives you a standard interface that packagers and users would expect for build software and you don't have to rewrite your DAG every time by hand.

>And again, you still need to spawn processes and transfer state through a fragile text interface.

You break the task into multiple parts so you hopefully don't have to run it all every time.
Text files aren't really any more fragile than any other way to tranfer the state, just write a json or whatever format you like.

>And most languages' syntaxes integrate even worse with Make's than sh does.

What integration do you want that you had in your silly hand written one?

>How do I insert commas between words to generate python lists would be my first question, and frankly I do not want to know the answer.

You can either construct a macro to do this or you can just give the data space delimited to python and change the spaces to commas there. Surely you know how to do it with python so why are you insisting on doing it with make?

>It's not true that it's impossible to design a system that was better than Make.

Of course it's possible. Too bad no one has actually attempted it.

>And the "compatibility" argument is just not there, sorry. Yes, I require python, but that's it. I wrote a simple script that just runs and build. Nothing wrong with that.

You also require your own library. Most people probably don't have this installed. Also if you wrote this at a company and left then they'd have a half-baked build system and they cannot hire anyone that's familiar with it.
Football toy chest! I had one of those. I remember climbing inside it -- being able to fit inside it even.

This article seems like it’s written to be deliberately confusing.

If I understand it correctly, the TSA is not forcing anyone to unlock devices. They take the devices away for some period, but if they’re securely locked, TSA won’t be able to get anything from them.

However, the article drops border searches which do require an unlock right into the middle of the article, then goes on to say that they have no specific examples of TSA doing the same thing. This implies that they have reason to believe it’s happening, but as far as I can see there’s no justification for that.

The big question is: what are they doing with these things? If it’s some fancy explosives sniffing (like they already do to my contact lens solution) then it’s nothing interesting. If it’s an electronic search if unsecured devices, that’s bad. If it’s an attempt to force travelers to unlock secured devices, that’s horrible. The article seems to want to portray it as the last one, while only giving evidence for one of the first two.

Not likely to work: "We just want to search your house for 30 minutes" or "you can have your document back after we photocopy it, so no warrant needed."

The idea is that they cannot do certain things without a warrant.
They can have my device if necessary, however I will not give them the passcode without torture. They can add it to the pile.
Stop flying so much and tell them when the time comes fuckoff and come back with a warrant or at least get an officer who can explain under what authority do they conduct domestic searches without a warrant, ergo, unconstitutionally?

As someone who writes for Packt (Posting under a throwaway for obvious reasons), I think you made the right decision. The first title I was proud of, had good editorial control and decent technical review. The second title had an awful premise that was insisted upon and stunningly poor editorial control. Disappointingly I now feel like I have to apologise for something that carries my name.

My next title will be self-published onto Github on a 'freemium' model. It'll allow me to develop the content in the open, and if people are so disposed, they can pay for an edition that carries additional explanatory text. Either way, I won't be writing for Packt again.

Dietary phytosterols lower cholesterol but do not reduce CVD or all cause mortality[0]. I don't remember the other names, but phytos are just one of many classes of agents that have been shown to reduce cholesterol without any other beneficial effect; IIRC, other than statins, there is only one other class of drugs that reduces cholesterol and reduces CVD.

LDL correlates trouble, but evidence that it is part of the problem when I last looked was not well supported (though it is generally accepted in the medical community)

I wouldn't say "classic" since you're referring to fairly recent events. If I had to guess, the OP was speaking about mid-20th century targeting of progressive groups by US law enforcement agencies (e.g. sending MLK fake hate mail whose intent, according to many, was to induce suicide).

For me the issue is the broad application of troll and liberal banning. I was all on board the detoxify train until I was banned from a subreddit where I had posted for 5 years.

I didn’t know what comment or behavior. Messaging mods said that it was obvious what comment and that I was a troll.

This was confusing to me. I never went back. Now I am skeptical of labeled trolls unless I can assess behavior directly.

You don't need to copy immutable values.
The real issue is binary choice. I might disagree with a comment, but acknowledge it's a valid well thought out argument. On the flip side I might agree but acknowledge it's a poorly formed argument.

Something might be totally off topic or funny, but if I made me laugh do I down vote it?

Slashdot's model of tagging posts was a pretty good idea I think and allowed one to filter out the 'funny' or 'offtopic' comments.
By "that's how languages form", I assume you mean something like "standardized languages", which then becomes somewhat circular, because it's certainly not how languages form generally (and even standardized languages can form without mass media, and certainly did, even pre-writing).

That's also not how standard French formed. Standardized French is Parisian French, so just the 'dialect' of the politically-important centre. Not too dissimilar to Latin (which was originally narrowly the dialect of Rome) in that.

Whatever the propaganda, China still contains a number of non-mutually intelligible (though related) languages, but of course Mandarin enjoys much prominence and has an enormous number of speakers.

> Heap allocated vs. stack/statically allocated.

`str` is very rarely stack allocated, and often points into a heap-allocated `String`. Further, there's an optimization on the table that will let `String`s point to static allocations.

The distinction is rather owned vs borrowed. A `String` is in charge of the memory it uses, so it can grow it by reallocation, free it when it goes out of scope, etc. A `str` is not in charge of the memory it uses- it's only a pointer into some memory that something else owns, whether that's a static allocation or a `String` or some other data structure.

Link to GitHub: https://github.com/tensorflow/models/tree/master/research/de...

The README on there has a very neat TLDR of the model:

"DeepLabv1 [1]: We use atrous convolution ['s a shorthand for convolution with upsampled filter'] to explicitly control the resolution at which feature responses are computed within Deep Convolutional Neural Networks.

DeepLabv2 [2]: We use atrous spatial pyramid pooling (ASPP) ['a computationally
efficient scheme of resampling a given feature layer at
multiple rates prior to convolution'] to robustly segment objects at multiple scales with filters at multiple sampling rates and effective fields-of-views.

DeepLabv3 [3]: We augment the ASPP module with image-level feature [5, 6] to capture longer range information. We also include batch normalization [7] parameters to facilitate the training. In particular, we applying atrous convolution to extract output features at different output strides during training and evaluation, which efficiently enables training BN at output stride = 16 and attains a high performance at output stride = 8 during evaluation.

DeepLabv3+ [4]: We extend DeepLabv3 to include a simple yet effective decoder module to refine the segmentation results especially along object boundaries. Furthermore, in this encoder-decoder structure one can arbitrarily control the resolution of extracted encoder features by atrous convolution to trade-off precision and runtime."

At the basic level, there are two types, same as let's say C++ offers std::string, and char*.

Strings are really a hard thing to begin with, many languages simply obscure their complexity.
True — it wasn't clear to me whether e.g. a random temporary filename would be considered static or only actual fixed strings in the code. (Similar questions would arise if e.g. a web app saved things using a database primary key so it's technically not static but the attacker doesn't control it even if they control the file contents)
