As far as I know, the fastest production Z-80 chip (the Z-80H) ran at 8MHz. This one runs at 84MHz per CPU!

I switched from 8-bit (Z-80B) hardware to 16-bit (i386) hardware once the 16-bit PC could emulate the Z-80 faster than any physical Z-80 processor could run. I feel fortunate to have skipped the 8088 and 80286 PCs which all ran slower than my Z-80B for most things.

I kept one of my old CP/M machines in my parent's garage for 10 years, and then tried to resurrect it. It was an IMSAI 8080 with CompuPro hardware that I had modified to allow the front panel to work while allowing the system to run at 4MHz. I had also implemented software configurable baud rate and start/stop/parity selection by hacking the hardware and customizing the BIOS.

Unfortunately when I resurrected it, it booted and ran for only a short time before the ST851 hard drives scraped the oxide coating from the system disks. (I destroyed all of the backups while troubleshooting.)

I gave the whole system away before I discovered that they are actually still quite valuable, but I have no regrets. I much prefer a more modern computer.
Probably much more difficult than just turning off Bluetooth.
I see lots of families at Tesla superchargers, so apparently there's more than one opinion about that sort of situation.
Don has made plenty of political posts with releases of Notepad++:

He's using the platform he's got to push a message he believes in. I'm not in either camp here, but Notepad++ is particularly useful software, so I'm happy to keep using it.
Yeah, this tweet-complaint list is simply not true. SRO/Tenements are obviously not legal (for good reasons, imho). But the other examples in the tweet thread are legal in most cities, and these get built all across the US literally every single day.

In my small-ish Michigan city alone, we have multiple examples of #1, #3, #4, #5, #7, and #8, all of which have been built this decade. The same is true in Minneapolis, and Portland, and Seattle, and Chicago, and others.
Unionizing is the solution to unfair leadership. If the workers are hard to replace, then forming a union will probably work. If they're easy to replace, then they're getting precisely what their labor is worth. Since the wage seems to be higher than minimum wage, there's obviously some value in keeping them, which means a strike may work.

Unemployment is very low right now, so I'm sure there are plenty of other jobs available. The fact that people continue to work for Amazon suggests that quitting is worse than continuing to show up at work, so I'm really not sure what people expect. I'm guessing it's just that Amazon is seen as a tech company and therefore is expected to treat their warehouse workers closer to tech employees than warehouse employees?
That thing obviously cannot be used just like cash. Jesus how fucking dumb are you people
The trivial cost of adding one outlet when building a new home is not what is preventing poor people in California from buying a home.

The price is in the land not the building.
I've never understood how they got the existing salt out of the water in the bay there after they completed the dam. Is that clear to you?
US media is distinctly anti-brexit, and paints leavers as uneducated xenophobic nationalists. Personally, most americans I know are mildly pro-brexit. Seems to echo our national narrative of the nations birth, and sovergnity. Most americans seem not to have a strong opinion on brexit, although most are familiar with the term.
One of the restart popups came up while I was typing, and I happened to press the space bar as it appeared. I believe it chose "restart tomorrow" for me but it disappeared I cant be sure. Sure enough, the next day the pc is restarted, despite me having hibernated it before I left. Hibernate isnt even safe! Event viewer seems to show it waking itself up from hibernate on its own, an hour after I left.
I agree that it is an intriguing concept. But at the same time they seem to be ready to sell Kong for $$$. And they don't explain why there are three tiers of rarity to the cash - shouldn't 500 KONG == 500 KONG all the time every time? Seems like a mechanic to raise more money, just like 'rare' cosmetic items in video games.
> Laptops don't propagate Bluetooth advertisements while closed and hibernating.

https://support.apple.com/en-us/HT204032 (Specifically, the Wireless Wake feature works over Bluetooth as well.)

Every Mac has Bluetooth always on unless explicitly turned off. As another commenter mentioned, you can see this by turning on bluetooth headphones near a Mac with the lid closed. The Mac connects basically immediately.
Some do. But MySQL is far much more popular on large scale environments.

In Google BTW I'm not sure how much MySQL/MariaDB is left at all. They have been moving most of the stuff to Spanner.
They can't read them in transit, but if you use Facebook's app to decrypt the message (which is the only option) then obviously Facebook can read your messages if it wants to.
That's great! The idea of a cluster with a wireless interconnect is hilarious to me for some reason.
I think you meant Douglas Adams. Also, AFAIK he never released any for CP/M. Those began in the PC era.
git reflog can be used to restore the last good commit before a rebase gone wrong. It's more of a pain to use that just resetting to a tag, but, it's a great safety net.

Line rate is just bits per second. You have to add in a qualifier about packet size before you're talking about packets per second.

https://en.wikipedia.org/wiki/CDR_coding

> In computer science CDR coding is a compressed data representation for Lisp linked lists. It was developed and patented by the MIT Artificial Intelligence Laboratory, and implemented in computer hardware in a number of Lisp machines derived from the MIT CADR.

> CDR coding is in fact a fairly general idea; whenever a data object A ends in a reference to another data structure B, we can instead place the structure B itself there, overlapping and running off the end of A. By doing this we free the space required by the reference, which can add up if done many times, and also improve locality of reference, enhancing performance on modern machines. The transformation is especially effective for the cons-based lists it was created for; we free about half of the space for each node we perform this transformation on.
This depends on how hard your BS program was / how much time and effort you put in.
I just built a 5x5 box for my kids and was also surprised by the cost of the play sand. Did a little shopping around though and I think I spent $200 CDN to fill the box. Most places I think were selling for $10-13/bag, but I ended up finding $5/bag play sand.
That's why I'm confused about Facebook claiming it's impossible. It seems clearly possible without compromising anything about the current level of security on the platform. They would have to develop specific functionality for it, but it is possible.
MP/M ran fine on the Z-80. Only the mnemonics were different between Intel and Zilog. The byte-level machine code of the 8080/8085 would run just fine on the Z-80.
Performance most likely.
Spent a good amount of time over there. GCC states shitting on each other is real "pot, meet kettle" hypocrisy and nonsense. And yes, we have two massive bases in Qatar. We can play all of the GCC against each other, but I can say as bigoted as it sounds: all the GCC states are repulsive and US support of _any_ of them is yet another sign of the US government upholding the stability of its values at home by subverting access to those same values for others abroad.

It is like we are all in an ironic race to the bottom for who can be most ironic with "do what I say, not what I do."

I'm guessing it was written in another language and its compiler produced the final JavaScript code.

This was inevitable. I suppose Apple's new "Find My Device even if it's offline" mode, which uses bluetooth to emit devices location, will help thieves to find these devices as well.
It's not even about reflowing text, it's just the usual two-finger zoom gesture that gets disabled. I'm very accustomed to moving the large text as I read it, so don't even need reflow.
In addition to cons cells being forced in some scenarios, this is Common Lisp, not Lisp 1.5: Programmers who want performance for linear collections are expected to use data types like vectors, which are primitive and not implemented in terms of cons cells at all.

http://www.gigamonkeys.com/book/collections.html

> Vectors are Common Lisp's basic integer-indexed collection, and they come in two flavors. Fixed-size vectors are a lot like arrays in a language such as Java: a thin veneer over a chunk of contiguous memory that holds the vector's elements.2 Resizable vectors, on the other hand, are more like arrays in Perl or Ruby, lists in Python, or the ArrayList class in Java: they abstract the actual storage, allowing the vector to grow and shrink as elements are added and removed.
Yeah, because of that, it's really hard to get Alpine-based Docker images to work in some situations, for instance:

this: https://github.com/grpc/grpc/issues/18150#issuecomment-47999...

And this: https://github.com/pypa/manylinux/issues/37

I use Python. Anytime you need to compile the source to build a pip package and that the upstream package developer decided that they don't support Alpine's libc implementation (aka musl) then you will have a big problem, unless you can control your dependencies and include as few pip packages that requires compilation or find binary builds.

Alcatel is a competitor to Cisco. Most of the Cal State University system runs on Alcatel after some Cisco shenanigans.
Eastern Europe country, so when we finally broke off Russia we went to implement very fast Western technologies. This also coupled with the fact that during Communism era fixed phone were something to wait years to be approved off made cell phone penetration extremely fast. People were starving for communication so it didn't matter that we barely had food, we still wanted cell phones.

Actually there is a generated username that you can change from your user profile page that also works, but you should be able to log in using your email address (and password).
A large part of the reason it doesn't cost more is that a day care working can watch 5+ children at once, whereas a parent is probably only watching 1-2 kids.
>Life is political nowadays.

I don't know where the train left the rails but I think it's insane that politics, conversations about the people controlling our lives, became such a forbidden topic. We need to be better than that.
If you expand that to Z80 compatible chips, the fastest was (is, possibly, as I think it's still being made) the Zilog eZ280 at 50 MHz -- which, given that it runs at about three times as fast as the Z80 at the same clock frequency, is like having a 150 MHz Z80.

https://en.wikipedia.org/wiki/Zilog_eZ80

My TRS-80 Model 4 back in the day (circa 1988, I think) had been upgraded with a HD64180 CPU, which apparently could run at least at 10 MHz -- although I'm pretty sure the third-party expansion board I was using ran it at 6.144 MHz.

> Of course we're mostly data scientists now, because only 5% win the faculty lottery.

This seems like a sad waste of physicists, even if the faculty pyramid scheme is obviously unsustainable. I for one would like to see more actual advances in physics.
Sounds fair. I really like the technology though and think you guys have the most unique take on paper crypto so if the actual token itself becomes a barrier to adoption due to volatility/stability (which is a leading reason why stablecoins are all the rage right now - as I'm sure you guys are aware), you guys can license out the tech or produce bills for Tether, Dai, USDC, and other high traction stablecoins. Our small stablecoin team (releasing product Q1) would be interested ourselves if we were to ever get into the 9 figure market cap range.

> Rather, most people use laws to attempt to enforce upon society their visions of how it ought to look and operate (i.e. drug bans, zoning). My motivation for getting rid of _most_ regulations is ideological

Do you not see that, were you to get your way, you'd be doing precisely the same, just with a different vision?

If I want 'drug bans and zoning', for example, I'll be cross that you've used (perhaps lack of) laws to force your own liberal vision upon me.

And that's essentially how we've (in much of the world) arrived at multi-party democracy.
I believed so, but I guess that the numbers don't lie.
Overcast seems to satisfy all of your requirements.
Ah! yes, Clausewitz’s 10 dictums about war, of course. My favorite one is “War is merely the cohesion of 5G wireless to malfunction a nationwide digital.”.

Man, this Clausewitz guy sure knew a lot about wireless technology for someone living in the 18th century.
@author I have worked for W3C a while - think the best bet would be to fork the WebRTC repo and propose a new Draft/ an edit of the current via Github. Most guidelines and contact adresses are publicx available. Your looking to contact the "Web Realtime-Communication Workinggroup". Theres regular worldwide meetings in W3C where one or multiple representatives of a regional office are in an 1hr call together and update each other. If you'd send a motivated email to any local w3c office that would propably also make it to a discussion in such a meeting e.g. on how to treat individuals as the.current buisiness model of W3C relies on paid membership.

"he made a rails app while working for us so the rails app he made after quitting is ours. I can tell from the file structure and from having seen many rails apps in my time."
- made up person

I find it hard to agree with your first paragraph. Particularly regarding file structure. I assume there's 1000s of public github.com repos with exactly the same structure as OP's. I say it's not IP at all, let alone IP you can take from an employee... but I don't know.

Anyway can you elaborate on the e2e example or point to a reference? I am doing e2e testing for a large company. One major question is, can they stop me from doing e2e testing at another company? Either from an IP angle or a non-compete angle? The company is a widget maker, not in the business of e2e testing.
I agree with the second part (separate health insurance from employment), but I disagree that we need universal health care.

I think we should remove all incentives for employers to offer insurance and require employers to make the cash value of any benefits available to employees upon request (and make that option clear at hiring time). Basically, when your employer shows you a "total compensation" amount, you should be able to get that in your paycheck if you so choose.

I also think we should encourage (maybe require) insurance companies to offer long-term contracts at a fixed rate, adjusted only to account for inflation and changing costs (uniform across all customers). We can continue the subsidies for poorer people if we want. This would essentially be a market-driven "universal healthcare", but it's opt-in.

Maybe we need universal healthcare, but I feel like that's a bit overkill. I feel like we can ease into it by expanding on the ACA and getting more people to get insurance outside of their employment.
Thanks, I just forwarded all of this over to a family member who is currently trying to learn web development!

No, he meant Scott Adams. Not the Dilbert guy.

https://en.wikipedia.org/wiki/Scott_Adams_(game_designer)

The Scott Adams adventure game series was published around 1978-83, and started on the TRS-80 Model I. I don't know if there were ever official CP/M ports, but they were certainly of that era.
But there already is a backdoor that lets them read the messages. Facebook actually implementing the functionality to take advantage of that backdoor doesn't change anything. The security of your message relies on the security of Facebook's infrastructure either way.

If Facebook implements a switch in the app that would send your decrypted messages back to them, then a malicious actor would have to compromise Facebook to obtain those message. Right now, a malicious actor can obtain your messages by compromising Facebook and implementing that switch themselves. From a security standpoint that seems identical to me.

How so? If you have a deployment pipeline, wouldn't you just detect failures?
The "tiers" are just bundle names. We could have been super dry but decided to make it more like collectable cards packs; our expectation is that most people will buy Kong since it looks cool (that's totally fine with us). Our margin on Kong is typical of other startup hardware projects; not great. We're not raking in cash from a digital token sale.

We've made a physical product, we'll sell it to cover the costs of doing so.
Reading through the article and the other sources linked, this seems to be a different dataset and implementation than the "Have I been pwned" dataset that Firefox and other password managers reference. However, I don't see any information about where their data comes from, only information about how the feature/extension works to not leak your password during verification.
The kids spend 70 hours sleeping and 40 hours at day care... That's still 58 hours to spend with their parents. That's plenty of time! Nevermind that the kind of unstructured play with other kids at day care is exactly what young kids need anyway.
A Kong is worth what I think it's worth. If I saw Kongs trading for 1 beer in the morning and some guy insisted that the rate was now 1.45 Kongs a beer in the evening I might object.
It's fed by freshwater rivers, providing pressure pushing the water in the bay out to sea; and they open the barrage at low tide so that water flows out (thus why it's a barrage and not a fixed dam). And then close it again at high tide, so saltwater doesn't flow back in.
You're right, it's not a bugfix, but it is a security update. It makes your computer immune to most types of ransomware, which is a huge and common threat these days.

Not having that functionality was dangerous enough that someone wrote a very involved program called Little Flocker, which was valuable enough to be sold to F-Secure. Apple hired the author (although it is perhaps not directly attributable to Little Flocker, he was well known in Apple-related security circles prior) and in the next major OS rev after that hire, the functionality was included stock in the OS.

People running Catalina are at greatly reduced risk from common threats from malware.

It's absolutely a security update.
Disaster Radio. Does one need an FCC ham license to own/operate an endpoint? What are the frequencies? After some light poking on the website I don't see any info on that. Love the idea though.

Suppose you magically double the number of faculty positions. Within one year all of the new positions could be filled a hundred times over. Now you've back to the exact same scenario, except that now you also have twice as many slots for grad students, too.
The 6,000 number is creasing the kapton 180º over the course of half a second with the 6mm curve radius. Copper breaks but not the lines critical for validation.

Our goal wasn't to make this thing indestructible, it was to figure out where the bar was for "good enough".

USD benchmarks are roughly:

4000 folds
2 years lifetime (low denomination)
8 years lifetime (high denomination)
30 transactions before decirculation

For Kong we aimed for:

6000 folds
10 years lifetime
unknown number of transactions before decirculation. (Unknowable)
Survives a wash

I think it's sufficient for what Kong is now but we have ideas for improvement and I would love here yours. Specifically anything we could do on the ESD side.

It's called "poverty." Poverty is the reason people work for them
Tangentially related question: how does one learn "computer architecture" or "computer engineering" as a hobbyist? I'm actually not even sure what those terms really mean.

I'm amazed that people can build homebrew computers using Z80, MOS 6502/6510, or Motorola 68k series microprocessors.

I could buy one of those homebrew Z80 kits and assemble it, but I don't think I'll gain much real understanding just from the act of assembling the kit.

I have long wondered how things work down to the bare-metal level. What does it take to be able to design (and program?) a homebrew computer? Let's say I leave out the FPGA route and only focus on using real, off-the-shelf ICs.

I'm mostly just a software guy (I write Python, I've learned automata theory at University) but I haven't learned any real electronics beyond things like Ohm's law, KCL, KVL, capacitance, impedance as a complex number. I don't even know my transistors or diodes.
Thanks for the clarification! I hacked TRS-80 Model I hardware (for a friend), but I never cared much for TRSDOS or Lifeboat so I have missed out on that software experience.

I guess this was a port of the classic Adventure game to Tandy. I had the CP/M version (550 point Colossal Cave Adventure). I had played it even earlier on RT-11 where it took about half an hour to load from two 8" floppies.

As a noob I've really enjoyed Frontend Masters courses. Brian's courses are great, and it sounds cliche but the JavaScript the hard parts by Will Sentence really changed how I think about how JavaScript actually works.
