One thing I've never understood about 'moisuture-wicking' fabrics, including wool: The wicking needs directionality to be useful, it seems: What makes the moisture move in the desired direction, and not, for example, toward your skin or spread around your skin, etc.?

Hmmm... Doesn't stand the test of time your statement. They have been also very critical and honest with reviews of shit apple devices.
Apple does pretty clients.

They are completely unable to do "enterprise" which basically means ensuring your document is where you left it last and being able to restore it if you misplace it. Oh and being reasonably sure that the right people can access your doc and no one else.

Apple does profit and worrying about ACLs is not profitable. They leave all that boring nonsense to MS. They do pretty and expensive.

There is of course Linux too but we are too boring and niche to worry about.

My experience with CL (as someone who loves it very much) that while the syntax is relatively easy to use (with the CLHS caveats that you mentioned - does the list or symbol come first for GETF? is it TYPE-OF or TYPEOF?), there's friction around getting set up for the first time. I've tried to teach it to many people before and getting a sane development environment is orders of magnitude harder than with Python.

I find your "stream of consciousness" description to be very accurate, and it's one of the most addicting parts of it for me.

Now, if only it scaled better to larger systems, it would be perfect - I would like to have better types and type-checking, and macros that have access to type information, for starters...
This is sad. I used to have an Apple Certified Technical Coordinator and other official certifications when I first started out working for myself. Mac OS X Server did a lot of neat stuff.

Here's an interesting Apple brochure from that time:

Ask HN: Are developer job search/interview consultants a thing?
We've all been subject to the god-awful experience that is hiring in our industry, but personally I've had experiences bad enough that I think it's time for me to stop and "debug" my "process". (Quotes very intentional here!)

The problem is that every time I get rejected, it's almost always (easily 90%+) right after the final interview, on-site, the all day panelist thing. Now a few times, no problem, but over the last 10 years we're talking easily 65+ here. So something's clearly wrong. But the worst part is, when I've asked for feedback, I NEVER hear a word back!

So I don't know what I'm doing wrong, but clearly somehting's up. I need a skilled consultant that produces real results, and I"m willing to pay for that help. Thing is, I'm not aware of anybody out there who does this for real.

I've heard of services that let you record practice interviews and feed them to some AI, but that seems about as useful as a campfire in hell. Plus, give some company somewhere video recordings of myself? Privacy issues seem inherent, inevitable with that.

So no apps, I want a real human who knows what the hell they're doing and can help me really figure out what's going on here. I just don't know (a) IF that's a thing, (b) what to search for ("interview consultants"? lol no, way too generic), or (c) how to evaluate them to see if they really can help.

Since our industry has such a "unique" (more accurate term: "broken") hiring process (recurring nightmare), this needs to be an industry-specific thing somehow. I figure if anyone knows anything, it's ya'll.

So, any suggestions? Thanks :)
I've had a 5G phone for over a year, and have been ON 5G for maybe 45 seconds.

Said it before: Switched carriers to make the new one pay off my phone, then switched back because they didn't have 5G either, and their signal was worse.

We were promised one thing with 5G, and the end-user reality is much, much different.
Honestly, lately when I’m having poor loading times and latency on cellular data I often look and I am on 5G.
I do not need this, but TE makes very nice things and I love that they keep making new things.
Seeing that splash screen really tickled my brain. It’s likely rose tinted glasses, but I really miss the Visual C++ 6 on Win9x experience and all its associated aesthetic.
Or, let's blow the carriers' minds here, they can lift the data caps and just charge you little extra for a fixed subscription, as a good chunk of Europe's carriers already do.

An executive of the carrier I use even said in an interview that it's much easier that way for them, and they are not worried that people will stream 4K video 24/7. Few years down, turns out he was right to be not worried. I can stream a 1080p Twitch gaming video just fine -- and that's in a local mall with a very polluted radio spectrum.
Sound has two different speeds on Mars, NASA rover finds
In my city (Europe) many ISPs have stopped offering fiber and are now mostly pushing 5G "broadband connection". I moved last autumn and had to get 5G. I can attest that it is pure garbage. Connection drops several times a day and I have never seen speeds any faster than 4G, often dropping to ADSL speeds during high congestion. The modem is also buggy as hell and needs to be rebooted at least weekly (believe it or not - it even came pre-installed with a setting that reboots it every night!)

I am currently negotiating with two ISPs to get private fiber, because I simply can not work from home with this unreliable connection. It's going to be expensive, but OTOH adds to the value of my home.
You can read it after it gets wet, mostly / sometimes. Writing is another story.
No? Because this has nothing to do with free speech. Twitter is a clout farm and he wants to own it.
It's widely understood that switching to EV is part of a larger package of policies that can get society to zero carbon but it is nonetheless an absolutely necessary part of any zero carbon future. Tesla's role in pushing that forward is highly commendable, by any reasonable standard.
I use TMobile Home Internet that includes their 5G, both 600 Mhz (Band N71) and 2.5 GHz (Band N41). This means I don't see multi-gigabit speeds, but I routinely see 250-500 down/50-200 up on Band N41 and 15-30 mbit down/ 5-10 up on Band N71.

TMobile's 600 MHz signal just goes forever. A single tower can cover hundreds of square miles providing "LTE Speeds."

We live a mobile lifestyle, and 5G has been a massive win for us. We get LTE speeds out in the middle of nowhere and amazing speeds when we're closer to a tower. Last year, we spent a bit of time about in the desert 10+ miles outside Ely, NV. I was able to stream YouTube at 1080p without issue in the middle of nowhere thanks to 5G technology. Looking at CellMapper's data, we could have easily been much further out and still been fine.

I don't need multi-gigabit. I just need useful speeds, and personally 5G has been awesome.
I'm very confused by your response. Where did I suggest that I don't like type systems or think automated tooling is not useful?

It's precisely because I do like and use them that I find Python's static type hints to be extremely useful for large Python codebases.

What I hear you saying is "Python does not offer these things". What I hope you hear me saying is "Python does, in fact, offer these things".
I swear the clip art for 'mail' has a blue stamp on it. Amazing!
> The black text on white is too much contrast.

This statement intrigued me. Without getting into what is fashion and progress (because I am NOT a designer), I was curious what is "too much" contrast. There's lots of literature out there about applying too much contrast in image/photo elements. But here, we're talking about text, and this honestly piqued my interest. Too little is usually pretty obvious. But what is too much? I don't honestly know.

I found the discussion at https://ux.stackexchange.com/questions/123504/maximum-contra... pretty interesting.
Do your co-workers also only see the point of automated testing if you have 100% coverage?

If you/your team want to use a statically typed language, then use one. Python is not it.
Genuinely curious because I'm completely outside of this realm of research, but who would fund a study looking to judge the health implications of 5G? Cynically I can't imagine it being good for someones career in academia to publish against mega-corps who I imagine fund the majority of research in related fields.

This is all cynical speculation though, hence the genuine curiosity. I really don't know.
There is a weird hole where nation-states would love something with the rapid, global deployment capabilities of a nuclear tipped ICBM, but without the nuclear payload for fear of a MAD type retaliation. "Prompt strike" I think is the term. The trouble is, you'd want to be able to deploy such a weapon, but also be very, very clear it's not a nuke, just like a single building sized bomb or something.

Perhaps that's a use case for some type of space based directed energy weapon if you could somehow minimize the atmospheric losses to maintain effectiveness.
I learned how to operate tools safely in woodshop and it's one of the more valuable skills I picked up from my school days. I've forgotten most of my Spanish, almost all of the math, but I remember how to keep my fingers.
Every OpenBSD release comes with a comprehensive, release-specific upgrade guide which tells you all quirks (including changes to configuration syntax). For this version, you can find the respective doc here: https://www.openbsd.org/faq/upgrade71.html (Note the entire section called "Configuration and syntax changes")

There's also a pretty clear instruction at the top: "For critical or physically remote machines, test it on an identical, local system first."

I mean, I know it's annoying to hear that, but they are pretty upfront about basically everything with this OS, and you just have to be diligent about actually reading the documentation for the system upgrade. You were not "burned" by the OS or its developers.
You in USA?

Here in Sofia, Bulgaria (Eastern Europe) 5G definitely improved the latency of my connections, like a lot. Speed seems to be the same or slightly higher than 4G (which was also excellent but latency was sometimes erratic).
why don't you give this company a chance? I am sure there is room for innovation even if it's non oss it's fine along it's something new.

I'd like to see what kind of innovation they can bring to dotfile management.

I keep most of my important dotfile configuration in a private repo managed by stow/syncthing, but the management gets old after a while and the git commit -am "update" gets old after a while..

Somewhere between most and none, depending on the amplitude.
I can get an mmWave connection inside my apartment (just, if I stand by the window). If only Verizon offered home 5G in my area, I’d be able to get a dramatically faster connection. But no, slow cable it is…
I don't know, what about substack? People are seeking out journalism and paying for it.
I’m on an iPhone 12 Mini on T-Mobile 5G-UW and don’t agree with the sentiment here. Most of the time my phone feels like I never left my home’s fiber connection. I get a full day of use from my phone doing mostly email, slack, and the usual aimless browsing between life/meetings/chores.

The original “5G” that is just faster LTE? That was pointless.

Their 5G-UW seems to have a better reach than the LTE deployment so I’m generally happier with their service than before.

Eventually we'll be pixel streaming real time graphics and workstations (eg. Mighty) to our phones and tablets. This will enable entirely new types of content and productivity tools.

I’m glad you brought up the history of halitosis and marketing. In fact, the oft recommended twice-per-year visit to the dentist began as a pepsodent ad! It turns out that in low risk individuals, the frequency of dental cleaning and checkups did not improve oral health outcomes.

https://evidence.nihr.ac.uk/alert/dental-check-ups-every-six...

Now onto halitosis. Intra-oral halitosis is caused by volatile sulfur compounds and volatile organic compounds that are generated by microbes in the mouth: aka the oral microbiome. A number of studies have shown that halitosis is associated with specific bacterial species that have been shown to create these compounds both in vivo and in vitro. A good review on the subject is here:

https://pubmed.ncbi.nlm.nih.gov/32748883/

A number of clinical trials aimed at the efficacy of mouthwashes, probiotics, probiotics, lozenges have even been published. The general consensus is that mouthwashes offer temporary relief (through broadly decreasing microbial burden), and some probiotics are effective long term, but there is still much to uncover in this space as community dynamics of the microbiome are complex.

Do the 2 gbps speeds ever translate to any uses besides speed tests? I have gigabit fiber for my house and whatever CDNs are on the other side rarely seem to take advantage of the full bandwidth. For instance OS updates, Steam downloads, these all come in around 20-40 MBps (yes everything is wired not over wifi)

That's an important thing to keep in mind, but it also seems like the replication crisis is being fuelled by a kind of risk averse attitude. Something like "if you want to get funding and have your career go well, you need to make sure you're regularly producing positive results". From that point of view, not only is ambitious research (working on the most important problems in a field) risky, but so is any research that might not produce positive results. The safe path for scientists is to churn out a load of low quality papers where they're already pretty sure in advance what results they expect to get. And the replication crisis is a natural result. Careful science is in a sense just as risky as ambitious science, and God help anyone trying to carefully work on a hard and important problem.

To be clear, I'm not blaming scientists too much for having this attitude. I think the surrounding incentives play a large part, in particular how bad the job security is for a lot of scientists. Probably a lot of the people who would be working carefully on risky things ended up not being able to get a job.

Nor mine, it's the only Lisp-ism I choose not to try and integrate apart from trivial expressions. (I do rather like not having to type extra +s when I'm adding multiple things together.) Similarly I disliked my dad's postfix HP calculator apart from trivial things.

But this is Lisp, and my worries were solved when I was still just a toddler: https://github.com/quil-lang/cmu-infix Being in my .sbclrc file I can always use infix math whenever I need, and it's trivial to add it as a dependency to an asdf system.
It would be awesome if this existed, but they said that they have self-driving already, so the change would be minimal. This thing won't even have a steering wheel, so it's either going to run preprogrammed routes, or Tesla managed to leap from hands-off (level 2) to steering wheel optional (level 5) driving automation.

Sanctions have always been a thing. Confiscation of funds are an escalation sure but they are the logical next step when you’re part of a banking system that goes through the federal reserve.

The fed though is a good place to park your good or money. Allies of the US who park their money with the fed are assured it will be there, it will remain liquid, and any foreign actor that tries to take it by force will meet the US military which until tested seems to be the best in the world.
Anyone who can tolerate 40ms of latency should stick to Bluetooth. If it's more than 3ms, it's already more latency than a good RF system gives you, if it's more than 10ms things are getting questionable, and at 20+ms you've lost the ability to monitor, because what your fingers/voice do and what your ears hear are now noticeably out of sync. Try singing while monitoring yourself at 20ms delay. It's hilarious.
You should definitely give it a go! This is the SO post I mentioned, for what it is worth: https://stackoverflow.com/questions/31510930/rebol3-what-is-...

It was very easy to get Oldes' Rebol 3 up and running. It works. There are many extensions as well. My only problem is the lack of GUI (a huge problem, to be honest, because I want to contrast it to Tcl/Tk which I love as well), or at least I have not found the way to make it work. I might be doing something wrong though, or I might be missing something. I have not had enough time to search it up and get it to work.

Anyone who knows how to get GUI to work with Oldes' Rebol 3 please, let me know, it would be much appreciated. Any recent (and decent) Rebol (or Rebol 3) may suffice, as long as it is 64-bit.

[1] I believe it to be a major reason for Rebol not being used much. We need a proper, working Rebol! One working, actively maintained implementation, not hundreds of half-assed ones. :( I really hope Red makes it.
They also had three revisions of SIM in that period.

I'm not saying I'm not 100% on board with these changes; I'm saying that it's silly to depend on another company. because even the flagship product which is very mature will either change or be discontinued quite easily.
>> The problem with that is good art or even entertainment is rarely made by analyzing a spreadsheet to determine what audiences want.

To navel gaze, what makes good anything? (Forewarning I'm eventually heading around to talk about guessing ahead on whether we're making good software or not.) Good furniture, good cars, good bicycles... how & when are groups effective in these places? Or even in these cases, perhaps there secretly are individual craftspeople (I'd consider a moviemaker a certain type of craftsperson) defining the outcome, steering; we think of these industrial productions as group efforts but perhaps there really there are embedded decision makers.

Is good software made by analyzing a spreadsheet to determine what audiences want? In what cases? Who can determine what to build, based off what? Who directs the software, makes it happen, based off what?

How are we defining good, who gets to pick? Many more layers of questions here. In software, are we seeing & judging software as an appliance/application, or as technology itself is? If every engineer working on a thing says, this thing sucks, it's just the worst, but people love & use the thing, what does that say? What gives rise to tech that has a strong cult following?

Movies are interesting because we're incredibly bad at grabbing numbers about them. We can count the number of actors, budget & allocation of budget. But how do we rate & estimate story, it's value? How do we calibrate & rate the chemistry of the cast & the audience's reaction to these actors they may well already have seen in dozens of other films, how do we assess the photography department's choice of shots, or the special effect's team's spectacularness or believability? Everything is radically under-specifiable, as compared to a bike, where there are defined parameters & form, generally. Software too is another ill-defined thing, is more formless in nature; true to it's name. It has such a mound of cofactors constantly defining it. There's so much taste & necessary continual discernment, picking well, that keeps compounding, that comprises the whole, like a movie.

> what would it take to make a PC bootloader work just as nicely?

If we take Apple's bootloader as a base line:

Drop GPU support, except for blessed models, from initial boot support.

Remove RAM customization options. Can't change speed and timings. Can't support ECC. Might as well disallow customizing RAM alltogether and solder it to the board or in the SOC.

Remove CPU customization options. Can't change speed, enable or disable supported features. Can't chage ACPI tables.

Remove storage customization options. Can't change storage speed, protocol support. Can't even add or remove internal storage devices at all, if we go by the latest trend.

Implement a bluetooth stack onto the bootloader firmware, because that's for sure safe and could never go wrong. Force OSes to write their pairing keys in the firmware storage.

Implement a wifi stack onto the bootloader firmware, because that's for sure safe and could never go wrong. Force OSes to write their pairing keys in the firmware storage.

Implement internet-based, network boot support from a centralized, blessed location. Because that's completly safe and could never go wrong.
Wow, an entire article about 5G with no mention at all of all the new frequency that's been going along with it. Yes, existing frequency is no faster, and MM wave is not terribly useful, but that mid-band spectrum is pure gold. When people say 5G, I just assume they are talking about mid-band. It's like when we got 4G and all that new 700mhz spectrum opened up. It's all about the spectrum.
