1973 When Calculators Were Built Like Computers
Thunderbird still has a critical bug open that literally deletes your email. I have been bitten by it once and lost hundreds of email permanently. Not fun. I am subscribed to the ticket and every month or so someone posts an outraged "me too".

https://bugzilla.mozilla.org/show_bug.cgi?id=462156
The thing about massive conspiracies is that it only takes a single participant to leak their existence. And for a conspiracy like what you're suggesting, there would be tens of thousands of participants.

It's time to let reality back in and accept that there is no media conspiracy. The big tech companies overreached and now the roosters are coming home to roost after 2 decades of largely unearned fawning media coverage.
I use Thunderbird pretty much just for FiltaQuilla extension, which runs shell commands when email matching some filter arrives. It would be nice to have this functionality built-in and extended (e.g. email data could be passed to stdin).

The biggest drawbacks is overall slowness (especially when syncing with server) and search UI (which really needs to be condensed). BTW it would be nice to have option to search for all mails involving some address by just right-clicking the address, like in Mailspring.
Here's what HN thought about the 2009 predictions, in 2010 - https://news.ycombinator.com/item?id=1064789 .
Random other point of brilliance I've seen: Our Organic Chem teacher (who was loved universally in the Program) had a rule about test corrections. If you wanted a correction to something you believed you should get credit on, he would only offer to regrade your WHOLE test, which meant you could actually get less points on the regrade because it was he and not a TA regrading (could have worked both ways). It really scared off all those one-off "Can I get an extra point here" requests in a 300 person class.
Yes, you too!
It should follow 302s, but some are not working. It's on my bug list :). Thanks for the comment.
I've set up a regular monthly donation specifically to support Thunderbird development because having a FLOSS email client I can trust is extremely important to me.
NoRedInk | Full-Stack Engineers, Site Reliability Engineers, and Engineering Managers | San Francisco, CA | REMOTE Pacific Time (PST) to Central European Time (CET)

We’re an ed-tech company on a mission to help all students become strong writers! Our team may be small, but NoRedInk is used by 1 in 2 school districts in the US, and students have answered over 5 billion questions on our platform.

We’re a group of friendly people who listen to and learn from each other. We discuss past mistakes openly so we can adapt our processes to the challenges that come with progress. Puns flow freely across our San Francisco office as well as on Slack, and we have remote engineers spanning six different time zones.

Our engineering team [1] prides itself on code quality and innovation. We use the cutting-edge Elm programming language for all our new front-end code, and have been migrating legacy React code to Elm as well. Our back-end is primarily Ruby on Rails, although we are working to split off smaller services as we scale to keep up with our traffic. You can read about our experiences with these technologies on our team blog! [2]

In addition to spending work hours open-sourcing useful libraries we develop [3], we also invest financially in open source. We hired the creator of Elm, Evan Czaplicki, to develop Elm full time. [4] Evan discusses his plans for the language with the team every week, periodically pairs with other engineers on Elm, and cracks up members of the sales team with his lunchtime jokes.

We use Amazon AWS for our infrastructure and automate all of our deployments using Chef and OpsWorks. We write a lot of tests, and use Jenkins for continuous integration. Our process for new features begins with our product team and in-house visual designer, continues with a GitHub pull request from a feature branch into master, and ends with our in-house QA specialist trying to break it before it reaches production.

We’re looking for engineers who want to work on a mission that makes a difference and who are the type of collaborators that value kindness and open-mindedness, over convincing the group they’re right.

You can learn more about what to expect through blog posts about our interview process [5] and on-boarding experience [6].

Scribd has a very friendly, engineering-driven company culture with great perks for employees. We are ambitious but at the same time we value a good work life balance. In general we care way more about your personality and hacking skills than what languages you’ve used so far. We have hired many people from these “Who is Hiring?” HN threads, including myself. If you have any questions you can reach out to me directly at adrian at scribd.com or better yet apply directly at https://www.scribd.com/about/engineering
Here's how things went for me:

* Submit comment on GH issue

* Receive inline error

* Reload page

* Receive 500 error

* Check status page (all green)

* Wait 30 seconds

* Check status page (issues was red)

* Wait < 5 minutes

* Check status page (more things are red)

* Wait another few minutes

* Reload GH issue page, it works

* Check status page all green

The only thing indicating no errors for today is the manually updated text summary at the bottom. The automated dashboard was, for me, extremely quick to update.

Also, you'll need an extra line break to create a multi-line list.
Debt is a way to invest in the future. If the world is taking out debt and the investment is in enhanced productivity, better health outcomes, etc. then the debt is good because it more or less pays for itself. If the debt is used to make bad investments, things that won’t necessarily benefit anyone, then it’s bad.

It becomes not so much an issue of never having to pay the debt back because we owe ourselves and can ultimately write it off, but an issue of, at a certain level of easy credit, is it possible that it becomes impossible to keep making good investments. There’s definitely a balancing act in how much world debt is too much.

I felt that way when studying math in college, but after sometime I actually came to like the use of "clearly" and the like as it can be used as a check on whether you've spent enough time internalizing the previous information. It's one thing to have a text or a person hold your hand through algorithms or theorems, it's another to be able to do it yourself. So getting hit with a "clearly" that feels unjustified is often a signal to let go of the guiding hand and go back and review until the statement in question does become clear.
Ironic or not - I don't think you really mean they make up any lost tax on cars by selling oil - it's not like the oil sale increases by that virtue.
How ‘Magic Angle’ Graphene Is Stirring Up Physics
This is so. darn. cool!
In the early days of TCPIP, you needed a university membership to get access, and network-capable computers were even more rare. So you're saying that there aren't enough networked computers for blockchain to be viable?

We're currently sitting at around 8 networked devices for every human being, how many more do we need? 15? 20? What is holding blockchain back, since it is definitely not university membership?
I think the rule was you had to attempt at least one question (couldn't say "I don't know" for the whole exam). Am I remembering that correctly?
This reminds me of the song 'what Sarah said' by death cab for cutie.

"That love is watching someone die

https://www.thoughtco.com/why-it-matters-when-species-go-ext...

just one reference, it comes with breadcrumbs tho.
the way an ecosystem persists, is like a standing wave.
a small change can initiate a large degree of enharmonic disorder
another way of looking at it: realizing oil wealth is unsustainable and spending the cushion now to make the transition on their own terms instead of being forced to by climate uncertainty (annual record breaking fires, hurricanes, etc.) or market uncertainty (stranded assets).
Delphi 10.3 “Rio” has been released
Yes, that review also cites 94 references and (the core of the reference is 3 tables that reviews existing literature anyway) and was published in MDPI's peer-reviewed open access journal Nutrients. Every other publication I listed was also peer-reviewed and can be read in full and is also full of citations. That's sort of the point of having scientific literature.

But sure, since he's "highly respected" this Dr Greger sounds like a stand-up guy with no axe to grind, let's see: https://en.wikipedia.org/wiki/Michael_Greger as a "professional speaker on public health issues, particularly the benefits of a whole-food, plant-based diet and the harms of eating animal products" and the vegan publisher of the web site you cite as well, you don't say.

But, he's an academic? Let's see what he's published (lots of peer reviewed work on nutrition and metabolism I'd expect): https://www.researchgate.net/profile/Michael_Greger

Oh hmm, maybe I have the wrong guy, it's just a couple animal welfare papers.

Hey, up to you where you want to get your scientific information (same goes w/ the WHO, which I agree isn't a pop science source - it's a ... public health agency/policy advisory body). I'll just read the peer-reviewed literature, thanks.
Neither does the SEC investigation that got him for fraud

EDIT: SEO > SEC - Context switching is hard
Blender is (primarily) a direct mesh modelling software. A mesh is made up only of triangles of points. Circles or arcs do not exist, only approximations. This makes it unsuitable for making precise parts.

With direct modelling the history of an object is not modifiable.
So if you need to change something you did (because of change in requirements etc), you will need to undo and then manually redo all the following steps. Or to try to wing it by tweaking the end model directly. And then pray that everything was correct...
In a parametric model (FreeCAD,Fusion360) you select the operation that is responsible for that feature, make the change, and the rest of the model updates to match automatically.

In manufacturing 0.1 mm error for a single feature can be the difference between perfect fit and unusable part. How good the model looks is mostly irrelevant. Very different requirements from producing an animation or render, so the tools are quite different.
I can’t fully grasp the expansion of the universe. It seems intuitive to me that if something expands it must be expanding in something larger. Back when I was going to major in physics one professor told me to imagine a balloon expanding as a way of thinking about the expansion of the universe. It didn’t help me. A balloon can only expand since it is in a larger structure with room to expand.

So what is the universe expanding in? If this isn’t a valid question then how should I try to understand the universe expanding?
NeoSmart Technologies | SEEKING FREELANCER in industrial or mechanical engineering | Worldwide

We are an R&D company based in Chicago working on expanding into IRL automation and optimization. We are looking to hire one or more part-time engineers to assist with the design of mechanical components for an upcoming project. Must be able to think outside the box and come up with innovative approaches to tackle interesting problems.

Applicants should have experience with SolidWorks, Fusion 360, or comparable.
In regards to number 2. You can have variables and parameters in Fusion360 -- I use it all the time for adding a tolerance variable and stuff like wall thickness, length, width etc...

Are configurations significantly different?
Completely agree - being outside academia has apparently made me ignorant to a lot of the pitfalls to actually posting said solutions.

Makes perfect sense when put this way.

I also really appreciate the response from the author. I forget the gurus behind books like this often have a presence here on HN.
Would you take a risk on someone that graduated with below a 3.0 GPA with Cs in their math/computer science courses, but went back to school, took some core CS courses, aced them, got some research experience, and then applied to PhD programs?
Stella! And then everyone started calling it "wife beater", because whilst it was slightly more expensive, it had a higher alcohol content.

Weirdly I predict a similar fate: I expect some Cloud employee will walk off with some banks cloud-hosted server containing gobs of financial data (if it hasn't happened already) and that'll be the end of that. There'll probably be a rush of "security enhanced" cloud solutions after that, but it'll probably hurt them badly in the process.
Everyone knows they make a difference. But things like this are so complicated that it's difficult to say whether it's a good difference or not.
The Dangers of Elite Projection (2017)
> is in line with what Tesla had done with the Model S and X as production efficiencies allow them to reduce manufacturing costs.

Straight from Tesla's press release: "we are taking steps to partially absorb the reduction of the federal EV tax credit"

So no, this price reduction is not "in line" with anything in Tesla's past.
Honest non snarky question, why does it take 1,400 employees to sell mail order glasses, which are essentially a quasi-commodity product? What are all those employees doing? And since TFA says that balloons are put on the new hire's desk it implies these are all desk jobs, implying they probably outsource their manufacturing to factories in China.

I ask because I worked at a company that sold machinery at scale (which is much more complicated than glasses, which don't require novel engineering). We did all our physical manufacturing in-house, we had a manufacturing floor on the other side of the wall from the cubicles. We had somewhere between 250-275 employees to run the entire shop, that's manufacturing, engineering, software (embedded and application), marketing, IT, sales, logistics... Not sure if we outsourced our cleaning crew or not.

I wouldn't expect a mail order glasses company to have more than 500 employees.
The tax credits aren't for the consumer, they're for the manufacturer.

> The early adopters are going to buy one regardless,

Some of them will. The idea that there's isn't a demand curve for early adopters is insane.
Corona, popular 2d game engine now can be used under open source license

I think it depends on the context. I felt similarly until I discovered just how many machines attackers would pivot through in real-world attacks featuring strong adversaries. Preventing these attacks on every machine is a strength-in-depth measure.
In the far future. Tesla is unlikely to be able to wait 20+ years for driverless cars to become a reality.

This is the internet equivalent of those "get rich quick" TV infomercials, where the only people getting rich quick are the ones providing sham classes/books/seminars and charging outrageous amounts for them.
This is the best explanation I've seen. I think many commenters mean to say something similar but don't give enough context. Here's my phrasing of what I take away from tptacek's comment:

JWT is designed to be customized for a variety of use cases, which means programmers using JWT are rolling their own security scheme, including choosing cryptography from a practically unrestricted field of options. This is known to be a recipe for disaster. A good standard should provide an expert-validated scheme for a specific use case that gives end programmers assurance that if they comply with the standard, the scheme will fulfill its intended use case. This means standardizing separate use cases separately; therefore, JWT is at best a technology that experts could use (but probably wouldn't) to devise specific standard solutions for specific use cases which would then be appropriate for end programmers to use.
The Art of Vacuum Tube Fabrication
And how do you explain the past couple of years of uncritial, overly positive media coverage these companies have received? The media coverage that has created a rabid fanbase that surrounds these tech-personalities, making it near impossible to discuss the reality of the tech and finances of these companies?

Having to face consequences for your actions isn't a conspiracy. People reporting on these realities is not a conspiracy. It's long, long over due.
I would appreciate a version of the book with the extended material as well!
Is there a way to pre-pay advanced copies of the published book?
As a daily user my personal preference almost align with their goals. I look forward very much to the day that I can stop using mail-notification in Gnome. The Thunderbird built-in system has seemingly broken polling feature (not sure if it does anything when running minimized), and has no option to specify folders that you want fast notification when a new mail arrives. I always miss Gnome mail-notification when I am using Windows, and sometimes have my laptop running Gnome next to the Windows computer just for this purpose.

The second feature I would very much like them to work on is search. It is horrifically slow, seems to miss some mail (html only maybe?) and the result window has terrible UI. You can't preview why the search found something so either you run a more narrow search or manually go through each email it found. There is also no threading in the result window so you lose a lot of context.
Dismissing Bitcoin as vapour in the very early days (back when you could feasibly mine on a CPU). I still think it’s nonsense, but it’s nonsense that’s made the people around me who bought into it very comfortable!
You mean by selling oil and exporting those downstream carbon costs out of the country?
