High school trigonometry and introductory differential & integral calculus are not the kind of books being described in this discussion.

The example in the original post is books about group theory (or the group theory sections of abstract algebra books more generally). I can attest that this subject is very rarely described in textbooks with clear examples shown before definitions and theorems; usually the presentation is entirely abstract, following a pure definition–theorem–proof kind of structure. But many other areas of pure mathematics at the undergraduate level and above are presented in a similar fashion.

(I recommend Nathan Carter’s book Visual Group Theory for a lovely counter-example to the prevailing trend, which starts with the concrete, and is very accessible. http://web.bentley.edu/empl/c/ncarter/vgt/)
Linking Elixir processes together
Didn't Uber get a significant chunk of Didi stock when it agreed to exit china? I have no idea how uber is doing overall abroad but china didn't appear to be a total wash for them at least.
One of the comments: "truly this is the year of the Linux desktop"
Not true. Tesla has working advanced driver-assistance systems (ADAS) in the form of their "Autopilot" feature. This is as Level 2 (out of 5) on the autonomy scale. They are still very very far from Level 5. Much more so than Google.

Furthermore, they were getting their software from MobilEye, an Israel-based startup but cut ties with them last year and are developing their own Autopilot 2 program, which so far has not reached parity with MobilEye's Autopilot 1.

Still a long way to go and will be interesting to see whether they catch up to Google with all this crowdsourced data they collect.
Because fear of the unknown is stronger than fear of the beast.
I thought Uber stopped that program after the red light thing? I assume they mean the same though because Google have had self driving cars in Mountain View for years - this article claims 2 million miles last October : https://www.wsj.com/articles/googles-self-driving-car-progra... I'm not sure how that stacks against competitors but I imagine they're a long way ahead.
Oh, I'm not saying it's not available to those without employment, I'm saying it's sickening that it is very often tied to employment, for those that have employment.

Ones employment and ones health should not be linked in anyway whatsoever, lest bad things happen.

Major versions of OpenBSD are only supported for 5-6 years.

I thought that security updates are only made for -current, the current stable release, and the previous stable release. So, 1 year of support, not 5-6.

A cursory look at the errata seems to confirm this.
Here is my take on it few years ago. I tried to make it more like magazine, and get article text and photo, and there is a section with only articles that reached top position.

Wait a few years, children will grow old enough to inherit the old iPads, and there will be another boom.

Thing is, iPads are powerful, even though Apple tried their very best to cripple most of them by software updates.

The vicious circle is, that people who are not power users (demanding the latest features) are the ones less likely to update the software.

So here we are, with a ton of iPads working flawlessly with their stock firmware.

I mean, even I still own a first gen, just for kicks (and synths, synthstation49).
Because it is.

Here is a quote from wikipedia, from a sentence with 3 citations at the end of it:

OK, but that is more of a convenience for American tourists who may not have a local phone number to sign up for Grab than an actual service. People that live outside the US are not going to have the Lyft app in the first place.
If you see a stylus they blew it, said Steve Jobs about tablets that required one.
My ex wife won one and gave it to me. I use it in the kitchen(I'm a head chef).

I watch Al Jazeera news, listen to music and do my monthly stocktake on it. Occasionally I'll send an email etc.

It suits my needs as I don't have room for a laptop(I can stiff the iPad on the shelf when I get busy and still hear my music), I can do basic Excell input(I designed the sheets on a PC though).

In my mind it's a support tool, not a primary tool.
Can also confirm no issues with this transcoding on the C2758. I built a SuperMicro 4 drive NAS a few years ago based on this CPU and it has been very solid. Doesn't run well in Docker, but runs well baremetal.
It's not actually like that. They have a heavily restricted backbone and lots of little isolated networks hanging off it. This is lots of independent cases of idiocy causing infection.

You shouldn't need to upload the entire 1gb. The central AI can query the cars to get just the bits it has questions about. Part of the AI's job is learning which data to care about and which data to ignore.

A self driving system needs to solve this problem (the frame problem) anyway. So you get intelligence compression for "free".

How to Build a Mobile App Startup That Makes Money
Most of the SEs, in my experience, dislike questions, like this one, that boil down to subjective opinion. This makes them hard to answer, as answers no longer depend on fact or statistics, but someone's opinion of something. Frankly — while I feel for the questioner, and agree w/ him — this one seems very close to that edge.

It isn't immediately clear to me that this question is relevant like you claim; the FAQ isn't really clear on it either:

> The site works best for well-defined questions: math questions that actually have a specific answer. You'll notice that there is the occasional question making a list of something, asking about the workings of the mathematical community, or something else which isn't really a math question. Such questions can be helpful to the community, but it is extremely tricky to ask them in a way that produces a useful response.
How to Transfer iTunes Music and Videos to Galaxy S7/S7 Edge/S6/S5
I respectfully disagree. Every company I've been part of moving to the cloud already had plenty of hardware. It was ease of provisioning VM's, backups, deployment, and networking that really convinced them.

VMWare comes close to offering the same thing on premesis but Oracle is too obsessed with wringing money from it to let it reach it's full potential.

Why do people love to trot out that Steve Jobs quote and then completely misinterpret it? The context of that quote was a device that requires a stylus. Steve was not dissing the concept of styluses in general.

I totally agree with you, except that asking users multiple times for their password will increase password fatigue. It may be argued that we could prefer the users to mindlessly click on Yes when a popup arises, instead of mindlessly inputting their password. Another option can be timers on the Yes button (like Firefox does), it blocks a few user interface hijacking attacks and gives the user an opportunity to think before they click.

When Samuel Beckett Drove Young André the Giant to School: A True Story
I was almost convinced there, as a low cost retro games emulator that didn't look horrible under my TV... until I noticed that there are no audio ports on the back of the unit. As there's also only VGA/DVI you are stuck for a nice clean way to get a video+audio signal to your amp or TV.

The moment you start having to plug extra bits in (i.e. USB to SPDIF) you've completely undone the the reason to get one imho.

I'll stick to my bread-box mini-itx units. That said, I do like the custom integrated PSU in the Dell.
Moreover there is no trivial way to verify that https://github.com/mjg59 is github accout of Matthew Garrett. So all one needs to do is to create account that looks good and most people assume that it's safe.

Obviously I'm not saying that this is the case here. But it might not be the best idea to run whichever github project someone links to under root.
As opposed to others, I would like to agree with you. One can make design decisions which allow for maintenance over a very long, or indefinite period. This would require using formal methods and a different hardware architecture. Unfortunately, in today's world, we are stuck with mantras like "move fast and break things", which entails running away from, instead of fixing, the complexity we leave behind.
> ... are good examples how much safer open source actually is.

Sorry, open source never equals free software (most of the time). Though what you said may be true for both.

And some day, we will surely know why free software is better than open source. It's only a matter of time. But by the time, it will be late, and out of control.

Reddit is all over it although it has turned into something suitably reminiscent of Alex Jones' material. Jeremy Hunt is apparently directly responsible for running XP on all NHS equipment and pulling the plug on the support contract for post-extended-support causing the deaths of thousands of people while he rolls around in the dust of the crushed skulls of all his victims.

I would rather see it used to leverage an opinion against back doors and surveillance culture but alas this is merely administrative incompetence and failure to either upgrade or airgap systems which have had a clock ticking on them and plenty of notice from the vendor to sort. The buck should stop at the trust IT directors as this was entirely avoidable with a properly managed estate.
I would think of it more as a smoke test than a burn-in test.
The iPad Pro doesn't require it. It is an amazing value adding tool though if you know how to use it.

Not so sure that's a good idea. This would prevent users to programmatically compare hashes, and it would be hard to display one next to the other to facilitate comparison. Keep in mind that it is relatively easy to create a file that matches the first and/or last N chars of a hash. And who checks the center of the hash?
No, we have to have the browser compare the full hash and give a simple green light to the user. I don't have a proposition in terms of UX but it should be studied (should have been 15 years ago actually)

I had a couple drivers tell me they'd use Lyft until they had too many hours and we're forced to take a break, then they switch to Uber until the mandatory Lyft break is over. I forget how many hours they said they drive on average, but it was a lot.

Thing is, iPads are powerful, even though Apple tried their very best to cripple most of them by software updates.

There are other plausible theories:

1. When the iPad was introduced, the average smartphone screen size was between 3 and 3.5". I couldn't find statistics for 2016, but I would guess that the average is just north of 5". Large phones have considerably more screen estate than they had in 2010, so a lot of things that were done on tablets in 2010 can now be done conveniently on a phone.

2. There was initially a lot of enthusiasm for the iPad and other tablets, but over time people realized that iPads are mostly limited to media consumption. The form factor is not convenient for serious work.

In the end it's probably a mix of all of these: people wait longer before upgrading tablets; phablets have cannibalised tablets; most of the initial tablet hype/optimism has died out.

Exactly, FreeBSD uses the simplest solution for the task, in the name of security. FreeBSD isn't "secure from Heartbleed because they don't use Bash" but rather, FreeBSD is "secure because by default only the most basic, necessary software is installed" which happened to be sh instead of bash.
Agreed. I imagine a more likely scenario is they slam on the breaks by raising prices and firing a bunch of people before they run out of money. This of course would tank the companies valuation and result in a big decline in ride traffic. I'd be really surprised to see uber completely go away. I think the worst case scenario would be for them to go public and have their valuation impload, I.e a groupon like outcome.

Very interesting, thanks for the answer! For the application and data structure I have in mind, I expect to need lots of range iteration over small values (<32 bytes?) and relatively infrequent writes, so Badger might not be a good fit. At a minimum sounds like I'd need to set up my own benchmarks.
Do you really think that the machine does not handle credit cards a well? Provide a daily management report? Report inventory? Provide a Facebook interface between customers via the big blue E icon?
Sort of a side note here, but I think this is a big misunderstanding about Apple. Sounds crazy, I know, but hear me out before judging.

I think with Apple it's more about allowing the end user (the real end user, not the end user's boyfriend/girlfriend/wife/husband, child/sibling/parent, boss/teacher/roommate etc.) to have control over their own information.

In order to enforce this end user control, Apple needs to lock out rogue programs. It can't do so 100%, but it tries to get as close as reasonably possible. They try even harder with mobile devices, because mobile devices tend to be so personal and capture so much private information of one individual.
In the 8 years since I bought my current laptop (and still daily driver) I've bought 1 tablet (still using it after 6 years) and 4 smart phones (of which I only use 1)

I'd say this assessment is clouded by your own judgements of Uber. Uber is vastly larger than Lyft. I've taken Uber's all over the world (Europe, South America), Lyft barely has market penetration in rural areas of the United States.

I recently bet my friend who is supremely confident that United Airlines business will be significantly impacted due to the passenger incident. Thus far, it appears United is doing just fine[1], in fact they may be on pace for a blowout Q2 quarter. Money in the bank.

Moral of the story... These types of negative incidents (In my opinion I call it the constant outrage complex) rarely affects finance fundamentals of solid businesses. If you want to take a moral stand against Uber you are absolutely entitled to that and that is fine with me.

I asked very well defined programming questions, that resulted in the same actions by SE moderators.
I think the reason why the iPad is down while the Mac is up in the market is that it is not a full computer. My definition of a full computer is that I (1) can write software on the device itself that (2) can do everything you could imagine the device could do, and then (3) distribute that software to any other machine, be it your second machine, or 1 billion of your closest friends, (4) define yourself under what rules and what price that software could be bought, and (5) at no point will there be any other party (like the device creator) that could do anything to prevent you from doing any of these steps.

The iPad is so very much lacking in all of these terms, and the Mac is not, to me it's no wonder why the iPad sales numbers are going down while the Mac sales numbers are going up.

> persistence can be better achieved by clustering

If you want persistence, then I'd recommend persisting to disk. While I've not had this fun with Redis, I've written code that took out an entire Cassandra ring. Were stuff only in memory, it would have not been pretty. Just because something is distributed doesn't mean it's guaranteed to never go completely down.

(That said, if you're using Redis as an in-memory cache, this is a potentially acceptable tradeoff.)
I live in Seattle and I just don't prefer Lyft. 100% of the time Lyft's estimated time of arrival is wrong. They say your "lyft" is reaching in 3 minutes when I can clearly see it can't come even in 10mins. On the other hand Uber gives pretty good estimation.

Same goes with estimated cost of the ride. Uber tell me exactly how much I will have to pay while Lyft says $7-$12.
Feynman learned mathematics from a series of self teaching books published in the 1940's suffixed "...for the Practical Man" and prefixed with Arithmetic, Algebra and Calculus. I have the full set and this is a rather good solution to the problem. They teach you insight and how to think about things as well as the mechanical aspects. This is IMHO a well solved problem if you don't mind skipping more modern abstractions such as limits.

From there he was given a calculus book, the title of which I cannot remember. I never got that far.

I suspect you have to at least follow the same path to have the same intuition.

Never. But it would be wrong for Ford to stop others to fix your car by providing no information about the car, which I believe is what Microsoft is doing with their obsolete Software pieces (including OS).

Pretty good post.

The abbreviated answer, for me:

A book open on the desk, another one open on my lap. I spent a lot more time reading programming books cover to cover than I do now, and I spent a lot of time in the programming bookstores that no longer exist, like SoftPro. In fact SoftPro was sort of like dessert when I went out for lunch.
