Maintaining a hackintosh is a drag. You never now if an update is going to break things. You have to jump though a lot of hoops to get things like iMessage working. Moreover, you have to be prepared to use random kexts from the net. You also miss out on many security features of the Mac (T2 and their secure boot mechanism).

If you want to run Linux or Windows, buy a NUC. If you want to run macOS, buy a Mac. Hardware-wise, the Mac Mini is comparatively expensive, but you also fund macOS development and will have a much better experience than any other hardware.

Source: I use NUCs (currently NUC8i5BEH for Linux, plus two other around the house), a MacBook Pro, and have had Mac Minis in the past.
To answer your question up front:

0. This is a new normal, accept that and make a schedule that illustrates your acceptance of it.
1. Google 'bodyweight exercise'
2. Plenty of sleep reduces stress.
3. Cold showers give you an adrenaline hit that is quickly followed by a very good feeling.
4. Don't eat junk.
5. Meditate: Sit in a quiet room and observe the thoughts that are consistently popping into your head. AFTER meditation deal with those repeating thoughts.

Just some general life advice from an old man: Postpone that wedding right now. It doesn't mean you love each other less. Imagine the relief and joy will have getting married without the looming invisible fear of a global pandemic.

Above all else: do whatever it takes to keep sober, you're doing great, KEEP THAT SHIT UP.
RedHat actually has /var/opt and /etc/opt which, while odd, makes some sense since /opt is a free-form /usr and still needs variable space and configs.
Ask HN: How can our startup better define our problem?
My cofounders and I have designed our prototype and developed most of the basic functions for the beta MVP version of our app, Athleticus.io. However our challenge has been narrowing our focus at such an early stage. I'm curious what advice the community may have regarding good questions to ask our target audience to narrow the initial problem we're solving. Any advice is much appreciated, whether it be questions or best approach on how to network/ promote an MVP. Thanks! -Ryan

I think of sales & marketing as two sides of the same coin, but the tactics change based on your deal size.

Coca-Cola have a field sales team, selling into convenience stores and gas stations and making sure the shelves are full, but that's dwarfed by their enormous marketing budget. It doesn't make sense to have someone making cold calls or doing door to door sales for a $2 bottle of coke.

Oracle has a marketing team, and they sponsor certain things to get visibility in the public eye, but almost all of their spend goes into a large team of salespeople. No Facebook ad, or coupon in the mailbox is going to convince a CIO to spend $5m on a new database solution.
I think it's a timeline issue. They likely have skipped A13X due to TSMC's fast cadence of 7nm+ and are working on A14. I'm guessing that A14X is destined for the Mac and next iPad Pro but that's maybe 9 months out? This CPU should be an A12X + extra GPU performance, but who knows what it brings.
Collapsing lists and a Compose message button are considered "big redesigns" these days?
One of my biggest concerns is that they mean well and rush these vaccine trials as having a vaccine very soon would be IMMENSELY VALUABLE.

But the fear part is that they screw up, people get hurt, and the anti-vaxxers dominate the conversation which leads to broader fear of vaccines and a vastly worse outcome overall for the foreseeable future.

I would not envy anyone who has to make such decisions right now. And I would respect the process as it is, rather than be angry at it, because vaccines are overall some of the safest medicine in the history of medicine and that's really important to getting people to use them.

APL was created by Kenneth Iverson (array based programming language still in use today in production at places like Volvo and sold by Dyalog APL) and Arthur Whitney (APL genius) made several APL like languages for banking/financial analysis applications in the late 80's in 90's to make super efficient stock ticker analysis apps. He funded kxsystems which is a very very fast memory mapped database technology that uses the "K" language which is like APL, but uses ASCII instead of Unicode glyphs. He made zillions of dollars then left again to make another company (Shakti) which uses a new version of his language. He writes a new one from scratch every few years. The "K" executable is tiny (something like a few dozen pages of C written in an extremely unusual style).

This guy explains it well although is a little zealous:

I've lived in Vietnam for the last 4 years and got used to the 'bum gun' as we call them. It is awesome.

I came back to the US late January for a meeting in SF. I was staying at my friends house and lamenting the missing gun. My friends were refusing to install one because they were afraid that their two year old would use it to soak the entire bathroom.

I started checking Amazon anyway... once everyone started stockpiling TP, the prices started to rise and I started to see more and more of them marked as 'unavailable'.

Now there is definitely no chance they will get one in the near future...

That goes back to if the decision to assign them is strategic, or not. If they wish to deprecate the language, it will not be done. Also one could argue that that small code change which took 5 minutes could have cost the company hundreds of hours supporting their clients if something happened. So that would make that very small change a very big change, not based on effort but on impact.
The difference is that a "discovery" is the result of an experiment used to support a theory. The results of an experiment can't be falsified, just more experiments can provide better data.
There's some debate about this if I recall correctly from the last deep dive I did about the pros and cons of it.

If I am writing a script that needs to be that portable, then I'll use #!/usr/bin/env sh but otherwise /bin/sh will work in all the cases I need it to.

Since bash's path might vary more, I might consider calling env to locate it then more often.
I think I was extremely generous with my margins and went to lengths to be selective with my inclusion criteria, I didn't even catalogue everything under those criteria, and I omitted huge swaths of web standards on the basis that (1) it was more forgiving to W3C and (2) they would be difficult to compare on the same terms. At most you've given a credible suggestion that there might be an order of magnitude off, but even if there were, it changes the conclusions very little. I explained all of that and more in my methodology document, and I stand by it. If you want to take the pains to come up with an objective measure yourself and provide a similar level of justification, I'm prepared to defer to your results, but not when all you have is anecdotes from vaugely scanning through my dataset looking for problems to cherry pick.
iMac covers that for most people. eGPU’s also lets you extend the Mac Mini at the cost of more wires and boxes.

But, the Mac desktop gaming ecosystem is fairly anemic so I doubt most people get much from a better GPU. IMO, a Mac Mini + KVM + 500+$ gaming PC is probably the best all around option.

We don't have the same basic needs. People are running VMs on their laptops so they can test things in an environment similar to production without having to run extra servers for every developer/sysadmin to test with. Back in the 80s you're QA and Production environment were very likely the same!

I'll admit that modern text editors and communication software have grown resource hungry, but a lot of that comes from being able to deliver a strong, cross platform experience. I remember desktop Java doing much of the same with just as bad resource usage. Same with applets.
By “simpler” I’m sure they mean “lower memory footprint” and “more stable” - right?

I would really just be happy if they made the video calls work more reliably. It’s really important now that my whole team is working from home. It’s a common occurrence that video calls fail to connect and everyone going into a call has to restart their client.

Over the years Slack has become more and more bloated. I think the scope has increased beyond where it’s possible to have a stable Electron app. It’s a shame because the core functionality they offer seems like it should be pretty simple to get right.

> I find this very doubtful.

I'm sorry to say this, but I don't think you understand the meaning of coordinate invariance. Coordinate invariance in physics means that if you go from one set of coordinates, say (q1, q2, ..., qn) to (s1, s2, ..., sn), the form of the equations remain invariant (assuming the transformation is nice and smooth). Newton's laws aren't invariant under a general coordinate transformation of that sort, and this is precisely because the acceleration involves the second derivatives of the basis vectors. E.g., Newton's laws when expressed in polar coordinates would involve centrifugal and Coriolis terms, which are absent in Cartesian coordinates. Equations in analytical mechanics (e.g., Lagrange's or Hamilton's equations) are coordinate invariant however [1].

> The method described in this book makes this kind of problem very straightforward.

Perhaps we have different definitions of "straightforward", but most physicists I know would not consider using Newton's laws in Cartesian coordinates to find the equations of a particle constrained to move on a smooth surface straightforward. At the very least, one should try to introduce a local coordinate system on the surface. It can be done, no doubt, but it's way more cumbersome than writing Lagrange's equations involving the generalized coordinates on that surface.

> Note that both F and g have direction and magnitude in this word problem even though there are no basis vectors to speak of and thus no way we can represent any of this numerically without defining more mathematical objects.

No one is claiming that Newton's laws are invalid in different coordinates! Of course they are valid and F = ma still holds true. The invariance you're talking about is the general invariance of equations involving (polar) vectors. That's obvious since vectors are inherently geometrical objects. But that is in no way the same thing as "coordinate invariance". I'm not sure how the book defines "coordinate free", and I certainly don't have a bone to pick with anyone. But perhaps also look at how physicists define coordinate invariance, since after all it's something they've been doing for a while?

I still stand by the claim that this book is a pretty elementary one. Sure, you might've learned new things from this book, and I can see how many people would benefit from it. But if you think this is what counts for "advanced mechanics", then you're very very mistaken.

There really is no reason at all to not support macOS apps when you've given the device a keyboard and a trackpad+cursor. In a lot of ways, this form factor is exactly what I would want my Macbook to be... ultra-portable, touch-screen with Pen support, more dynamic hinge, and no touch bar.
> Now onto the new instruction:

Adding a special VM instruction for such operations as inheriting from a class is a strikingly bad design decision.

You want to minimize the proliferation of VM instructions as much as possible.

A rule of thumb is: is it unreasonable to compile into a function call? Or else, is it likely to be heavily used in inner loops, requiring the fastest possible dispatch? If no, don't add an instruction for it. Compile it into an ordinary call of a run-time support function.

You're not going to inherit from a class hundreds of millions of times in some hot loop where the application spends 80% of its time; and if someone contrives such a thing, they don't necessarily deserve the language level support for cutting their run-time down.
The CPUs in the new MBA have 9W TDPs.

OEMs can still control load performance, it's not entirely determined by TDP.

Anandtech has a good article: https://www.anandtech.com/show/13544/why-intel-processors-dr...

Depending on OEM settings and cooling capacity, it's possible for Intel CPUs to indefinitely run at greater than their base clocks and TDP.

GP is suggesting that in this setting, the set is Booleans, the operation is &&, and the identity is True. So taking your calculation of

a * i = a

the operation (denoted * above) is &&, and the identity (denoted i above) is True. Lets see how it holds out for all possible values of a:

a && True =?= a
let a := True
True && True =?= True
correct!

a && True =?= a
let a := False
False && True =?= False
correct!

Why don’t ISA-powered schools partner with existing social and religious institutions?

Taking a church denomination as an example, if you’re a member, the church can subsidize tuition, and then once you graduate, they can hook you up with tech industry workers that are also members of the church. Because the church subsidizes tuition, you give up less of your income once you graduate. This arrangement would reduce the “dead weight loss” of people going through the boot camp and ending up underemployed because of low social capital/discovery. As the alumni network of Lambda + church grows, a larger number of people will want to pay it forward by helping the next generation. The church would facilitate this process formally.
A "quick take" from another post on HN regarding this document [1]:

"It offers a detailed look at Douglas Aircraft and their doomed attempt to boost profits via outsourcing.

Those familiar with the commercial aviation business know that Boeing's "purchase" of McDonnell-Douglas resulted in wholesale importation of Douglas's accounting wizardry to what had been a largely engineering- and safety-driven corporate culture.

Relevance to the MAX fiasco and the tardiness of Boeing's NMA designs is left as an exercise to the reader…"

The word has. The specific meaning has not. That's a thing that Microsoft invented, after all. (Microsoft was even in on the inventions of its several clear precursors, for which the name "console" hadn't yet been ascribed, such as the VIO/KBD/MOU subsystems in OS/2 1.x.) Windows Terminal most definitiely uses consoles, with the aforementioned meaning.
> "generic production capacity"

Much like the generic scientist/engineer in video games (imagine telling a chemical engineer that they're suddenly a electrical engineer), there is no such thing as "generic production capacity". Specific high-tech industries require specific hardware and specific expertise (like the melt-blown fabric mentioned in the article) that you can't just keep on standby indefinitely.
From the hardware, yeah, Microsoft got that pretty spot on though I have to say this keyboard cover has some major advantages in thickness. and the ability to remove the stand.

The part they didn't copy is the software, because the Surface is little more than windows on a tablet still. The tablet life sucks, the interaction is poor, the performance slow and buggy (esp in comparison), but Windows makes a great dev OS. It's funny how different they are.
