My view on SysMLv1 is that domain-specific modelling techniques or tools are almost always far superior, and SysMLv1 therefore becomes a burden as you have to use the other techniques or tools anyway, and SysMLv1 doesn't have much to offer on top.

SysMLv2[1], which is work in progress, is more interesting because it separates itself from general domain-specific modelling techniques and tools by:

* Allowing definition of requirements

* Allowing modelling and checking of constraints/assertions

* Allowing modelling and execution of verification methods

* Allowing trade-off analysis where objects are instantiated differently to assess impacts

* Having the concept of concurrent/parallel states

* Having spatial, time and units concepts built in

* Allowing modelling with event triggers (e.g. when X happens, then the object's Y property increases by Z)

Graphical notations are still there but I doubt they will get much use. Instead, SysMLv2 introduces textual notations and I would expect this becomes the easiest notation to communicate with. Even for Object Process Methodology (OPM) which is frequently touted as being one of the better general purpose graphical (with parallel textual) modelling notations for readability, I always look at at the textual representation as it is easier to understand.

I think the intent is that SysMLv2 would allow you to specify requirements such as (completely made up scenario):

* [Site X] shall be located at [coordinates X]."

* [Site Y] shall be located at [coordinates Y]."

* A minimum of 15 [sites] shall be located in [territory X]."

* "Each [site] shall have a [line of sight path] to two or more other [sites]."

* "[Line of sight paths] between [sites] shall be calculated using [XYZ:2022 standard]."

* "Each [line of sight path] shall not exceed a length of 50000m."

* "For each [site] located in [territory X], [planning overlay X] shall not overlap."

* "For each [site] located in [territory Y], [planning overlay Y] shall not overlap."

* "Each [site] shall have a [chance of flooding] not exceeding {some metric}."

* "[Chance of flooding] for sites shall be calculated using [XYZ:2022 standard]."

You can then write many of these requirements as constraints/assertions in the textual notation and embed other languages within the SysMLv2 textual notation or call external software tools so that constraints/assertions can be calculated externally with external data, for example, GIS tools and data or historical records.

>It doesn't help to be optimistic about something that's not going to work.

Thinking a priori that it’s not going to work, here we have the true definition of a pessimist.
Worth noting, the national debt rising to new milestones isn't that noteworthy. The rate of the debt rising (budget deficit) is currently lower than it was in 2019, which is pretty remarkable imo.
Brain plasticity is real. If I dropped everything and devoted my life to studying Chinese I would still never learn to speak it as well as a child who grew up in China.

I think both effects have something to do with it.
Primarily because that scenario ignores the realities of hyperinflation. Default is bad, but hyperinflation destroys nations.
> Is the position of that window relevant?

Who knows!

This seems like one of the things that makes it hard to test intermittent fasting: there are a bunch of variables other than just the length of the window.
Someone like Google should have very good information on where their current customers (and their customers) are, and that alone could be decisive.

If many of the customers in Africa are already well served by Europe (think Egypt) or the Middle East, and of the remainder a large percentage is in South Africa itself, then South Africa makes a good choice for the first.

After all, starting in SA doesn't prevent them opening further datacenter in other countries as they grow.
Yes all large projects have risks, however it's ridiculous to say there's nothing unique about software. How often does a nail in one corner of a building become a dependency for a bunch of elements clear on the other side? How often does a dog house have to scale to a skyscraper because more people suddenly want to use it? How often do materials and laws of physics change in the real world? How often can you not get a clear answer on whether a specific requirement is necessary?

Software is arbitrary logic which many stakeholders expect to be magic. It's not the same as any kind of construction project.
Wonderful bit of history!

I'm one of the faculty that teach the current version of this course.

Would you mind getting in contact with us? We would love to learn more about PL/UM. It would mean a lot: {jmct|dvanhorn}@umd.edu
1 - World needs world class mathematicians to continue to evolve science for the betterment of humanity.

2 - Those world class mathematicians need to get started sooner in life to learn most of whats out there so they can work on extending the reach of collective human knowledge on Math. So, these mathematicians better get to calculus before they graduate high school.

3 - I wish there were two courses like "math for bright kids" and "math for not-so-bright kids". Since you feel you didnt need to learn calculus and, assuming you felt the same way when you were in school, you would be taking "math for not-so-bright kids" .. AND THAT would not have been acceptable to your parents back then.

4 - I wish teacher had magical powers to know who would go on to be a world class mathematicians but i dont think we are there yet but I feel if there are enough mathematicians in the world, we may get there some day. Case in point - Einstein did bad in school and showed his brilliance relatively late in life.

In any case - lets stop the bickering because you had to study little bit more than what you are comfortable with, for the sake of overall evolution. Theres more good than bad here.
Same, maybe BM is just too... pulp genre-wise somehow? Or too cruel while being fictional and Nobel tolerates cruelty when it's based on true events?
Not really. It is Paul. The debate was there and the dominate one is peter-james Jerusalem group. Paul actually lost if you read between the lines. Only later as that branch was sort of kill of and Pauline Christianity with the Hugh gentile group won. Then no Jewish law
Construction blueprints do indeed include a schedule of materials and finishes.
Ok, here. Let me Google that for you:

One of my favorite pieces of advice from shape up is using low fidelity mocks. We tend to overvalue visual work, so we love pretty high fidelity mocks, but when you're hammering out the details of UX and iterating that is just the flat out wrong way to do it. You don't iterate on house design by building the house, finding a mistake, tearing it down, and starting over. You iterate on house design on paper, where it's cheap and free and infinitely easier to change.

There still IS a time and place for high fidelity mocks, and they should of course be very well done. It's just that designing new functionality (key word functional) isn't that place.
There is a HTTP status code in any response and a 403 like in this case should already inform you about the problem. Pretty high level already.

I prefer to let the users actually see such errors, although that seems to be an anti-pattern today.

Usually any message receiver should first check the status code and only proceed if it is 2xx and handle errors in any other case.

But such edge case errors (a 403 usually isn't an edge case) getting swallowed still happens on the most prominent on thoroughly tested sites. Had similar stuff on Amazon and Microsoft pages for example. Saw the errors in the console but they weren't displayed to the user.
Having had to find a location to put a POP some years ago: Morocco, Egypt, Kenya, Nigeria are also OK, depending on your needs. WACS strings along the entire Western coast of Africa, so anywhere along there that you can get reliable power, you can probably get a drop from WACS to the wider Internet and run your services.

To your point, tho, I ended up putting the POP in Cape Town, because it's a mega cable landing site and in a developed country.

A downside: there are (or at least were) some annoying "data export charges" levied per-Mb by the ZA government on traffic to services hosted outside of ZA. That's the whole reason I needed to put a POP there to begin with. Our backups over the wire were a little expensive, though.
Forget Lexus, Toyota is the tech brand.

My 2017 Lexus RX has high quality adaptive cruise control (radar based), super good parking sensors, 360 camera, rear cross traffic alert.

But you know what it doesn't have? Automatic parallel park. My friends fking Toyota PRIUS has automatic parallel park!
Byproduct PMU foals cost less than a purebred kitten or puppy sold by a breeder, sometimes as low as $125. With two acres for grazing, annual cost of feeding can be as low as $100-$300 a year for an adult horse.

But, I believe, you are largely correct. I don't think rich people rescue PMU horses.
As an example, best practice for Palo Alto firewall setup is to create a rule that allows the "application" known as "SSL" and then use "application-default" as the setting for which ports to allow it on. This would inspect the traffic to determine that it is SSL (actually TLS in most cases I guess) and then allow it if on port 443.

If you don't have other relevant allow rules, your sshd traffic would just be dropped, regardless of port.

If the firewall administrator does things poorly, they will create an allow rule for port 443 and your sshd traffic on port 443 would be allowed (no inspection of traffic to determine if it is SSL or SSH).

BTW this is inspection, not decryption. Two very different things.

The business of developing algorithms to effectively detect various applications must be very interesting. You can see all the different "applications" here: https://applipedia.paloaltonetworks.com/
I also sensed this piece to be an emotional criticism to sprints, backlogs and tickets, lacking structure, evidence and logical arguments.

For instance:

> (...) they’re designed for managers who don’t trust their employees (if your manager needs to look at Jira to figure out what work you’ve done for your review or what’s shipped lately then they’re not paying enough attention to the team).

I disagree. Visibility and documentation of work are important for having everyone working in a project on the same page in an efficient manner, and definitely not a sign of lack of trust on the team.

From checking the author's information I found that he's a "writer and web designer". So maybe he comes from a different background that led him to develop this pessimistic views on scrum.

I'm personally more attracted to Kanban than to Scrum, even so I can see value in Scrum when run in a disciplined manner.
This is really cool as a demonstration of how distributed systems can be built on top of Durable Objects. In particular I was really happy to see this:

> What about replication? What about leadership election?

> There is none, at least not in the application code. The point of using Durable Objects here is that we can offload these complexities onto the infrastructure layer, and keep our application code focused and minimal.

Yes, exactly. With Durable Objects, these common problems are offloaded to the underlying system, and you can instead focus on the higher-level distributed systems algorithms problems that are unique to the particular infrastructure you want to build.

(I'm the tech lead for Cloudflare Workers and helped design Durable Objects.)
Gayle, and the Rise of Meta-Pop
The A1000 is a new model, the entire body is made of metal. The usual digital models are full resin, or resin cases with steel bracelets. They start from $15 or so.
They use the term informally. You seem to be assuming much more than you or they can know: that the signals picked up are, in fact random. Not understanding their meaning, if any, is fundamentally different from knowing they are random.
National debt in total numbers (dollars) is not only “not interesting”, it’s useless. In the same way that the debt of an individual is only interesting in relation to their capacity to pay it back, so is national debt only interesting in relation to that country’s GDP.

Many facts can be true at once. Here’s a fact: the US national debt to GDP ratio is higher than any other point in 70 years, probably more.

Here’s another: the debt to GDP ratio of the US is still lower than Singapore, Italy, Portugal, and less than half of Japan.

This headline strikes me as dishonest and political to the extreme. It insinuates quite simply that the US is in trouble, which the facts do not support.

National debt is not a bad thing by definition. The US GDP is incomprehensibly large at somewhere around $23T for 2021.
The point is that they don't "need" to respond with nukes. They can trigger article 5 and start a conventional war and achieve the same or better outcome; possibly without even putting boots on the ground. For example, NATO could (likely) sink the remainder of Russia's Black Sea fleet within a few days of triggering article 5. And/or they could actually establish a no fly zone and be fully justified in doing so.

Responding with a full on nuclear assault because someone first strikes with a Nuke that's smaller then those used in WWII doesn't make sense. You can probably do more damage with chemical, biological, or cyber warfare then a nuke like that (unless targeted at a dense population center).
America dropped 2 atomic bombs on military targets. The civilians were collateral damage, as always occurs in war. Attacks conducted by Japan, USSR, and other belligerents involved in WW2 also killed large numbers of civilians.
Well, that is fraud.

It is like employees need a lawyer in the room when it comes time for annual reviews.
Potentially, some, yes. However, when goals have already been decided, and 'missing' those goals is a 'bad thing', there's only so much you can do. We'd gone from collaborative to 'command and control'. And... FWIW, we got a lot more done under 'collaborative', but it was mostly just 'me' on the dev side and one other person on the product side.

At some point though, many of the original assumptions about problems are understood to have been fundamentally wrong/misaligned, and need some revisiting. You need to touch old code, whether to delete it, or to have it align with new standards or new ... whatever. Touching anything that didn't relate to an explicit 'agreed on' jira ticket was seen as wrong/bad. I ended up bundling in 'fixes' of unrelated stuff when working on 'new' stuff because... it had to get done, but was ignored or rejected during any sort of planning.

I've heard it said that "to go fast, do it alone. to go far, you need a team". I can get on board with that, but you need a team in agreement and competent. I have a colleague working on a small team and... they're mostly just completely inexperience and bad, but there's no self-awareness. Taking direction from the guy who was in high school last year, while ignoring the person who's lead multiple teams and has delivered high value software for 20 years... that's a bizarre imbalance that can't be fixed with 'sprints' or process alone.
Good point. Not sure why I even comment in here.
> because the crisis of 2008 was met with extreme money printing which did not cause a burst of inflation

The inflation was very much visible in the places where the people who received the money spend their money (i.e. Wall Street). The money never made its way to Main Street, so naturally there would be no price pressure found there.

This time around the money was distributed to Main Street.
> but there are no devs available where I live

If only there was a worldwide information technology network allowing people to work together remotely.
At the end of The Road, there are The Good Guys.

It is an allegory of fathers and sons.
We may not call people QA, but in the end each person has different skills, and the same problem will arise inside developers.

Anyway, the same happens for any multi-phase cycle. Like with code review. When there are dependencies between people, you are going to need extra items to work on while waiting, and this fights with the requirement that everything should be done at the end of the SCRUM sprint.
How good/reliable are the Johannesburg to Cape Town connections? I'd assume they're as good or better than the oceanics leaving.
The Delaware Court of Chancery is not exactly a small court. Almost every high-budget matter of corporate law goes through this court, and they regularly deal with cases involving billions of dollars. Given how important corporate law and corporations are, it may be the most powerful trial court in the country.
Here are a few reasons:

Cars still pollute - dust from tires causes harm to lungs and streams and is contributing to the decline of salmon populations.

Cars are heavy, damaging roads, increasing maintenance costs compared to electric bikes or public transit.

Cars are large, and need to be parked. That means larger roads and more parking lots, rather than using the space for housing, businesses, or parks. Bikes, buses, and trains don't have the same problem.

Cars reduce access to cities - highways and arterials are difficult to cross, and divide neighborhood activities.

Cars are dangerous, humans are generally only moderately adept at driving them. We have tons of injuries and deaths because people are bad at driving. (Or have to drive when they shouldn't.)

Cars are inefficient. The energy used to move 1 person via a car compared to any other form of transport is one to two orders of magnitude higher.

Cars require distributed energy rather than the centralized infrastructure that public transit requires, which means many small chargers rather than one electrified rail.

Cars aren't affordable for everyone, leading to inequalities in who is eligible to work at certain jobs.

There are probably more reasons, but cars are a deeply inefficient and costly means of transport.
Eh tbh I think it's directly related to the way that they decided to handle GPT and its iterations; they were worried that GPT would be used by bots to better spam the entire Internet, and to be honest they're right.

I'm guessing that worry translated to image generation as well. It's a Pandora's box thing I guess.
"Whereas CS arrays tend to be 1 dimensional, and sometimes 2 dimensional, tensors can be as many dimensions as you need."

You can have arrays of as many dimensions as you need in many (most?) programming languages.

Is there some other difference between tensors and arrays?

Or is it just the math term for multidimensional array?

Hah, it would get very boring, very fast...

When the area was first colonized by Europeans, the major hubs in the area were actually south of Syracuse, along the Seneca and Cherry Valley Turnpikes, which were the original east/west routes through the state, prior to the construction of the Erie Canal (the canal is a significant contributing reason Syracuse became the major settlement and the southern towns are just suburbs now). Due to those earlier settlements though, there were a number of water districts that predate the Syracuse city water district in the southern part of Onondaga County.

Those districts have now all been rolled into the county water authority, which coordinates with the Syracuse Department of Water to deliver water to the surrounding area.

Of interest to firefighting though, this patchwork of water districts that combined over time has resulted in a variety of different threads on fire hydrants, with "Syracuse Standard" and "National Standard" hydrants often being found within the same fire districts. Pretty much every fire truck/engine in the area carries adapters to convert from one to the other.
The right answer to the problem of "Tesla not having enough sensors" is NOT to rush into the hands of a brand who can't make an engine that doesn't grenade itself.

Oh, your engine made it past 50K? Good thing you're cars are gonna get stolen since they were too cheap to include immobilizers!
Thank you lord Kenton ^_^ I’m honestly looking forward to Cloudflare queues which is probably just built on top of DOs but its sooo nice having it as a service
Well, for them, it is and should be the most important thing. The problem bites when management shares that view.
The issue is that then you have to deal with a fascist machine that's hellbent on destroying your life for profit.
No. I do IF and lift heavy+cardio every early morning. I have progressively gotten stronger - benching over 330 and squatting well into the 400s.

Ive spent a lot of heartache and headache over research around these type of questions. The best answer is to learn what works best for your own body. Eat enough protein as a starter in any case.
> maybe less so for pre-meds

Yes, I agree that an industry that murders nearly a quarter million Americans annually through fully preventable medical errors needs to train their professionals to work with less rigor. YOLO, baby!
This number seems wildly low to me. I've been playing on chess.com for 2 years and have run into ~30 cheaters. I know they were cheating because chess.com told me they were. I've suspected a handful more of cheating who may not be as they were never banned. Either way this number doesn't seem correct.

I'd also bet some money on that. Even at a residential level, the fiber rollout in many suburbs and few townships allows us to remain connected during the 2 hour planned outages. A lot more people are buying small UPS devices to power our routers and modems.

A lot of businesses continue to invest in solar, I don't think a cloud provider that's carbon-conscious would leave their operations to diesel generators and mostly non-renewable electricity (https://www.eskom.co.za/dataportal/supply-side/station-build...). The link is to the supply mix over the past 7 days.

I'm South African, working remotely for a US employer. We often joke that my colleagues' broadband is 3rd world while mine is 1st world, as it seems easier to get a good fiber line here than there.
Dude.. it is the reserve currency.. when there are risks in the markets people RUN to it.

The same as when the markets are volatile people dump stocks and buy bonds.

Thanks for proving my point, that being a reserve currency gives you some pretty powerful special rights.
this project hasn't had a commit in 8 years and only has a handful of stars. It confusingly shares the name with a much more popular tool from Meta—though the use case is slightly different.

There are other much more popular tools that do the same thing, like entr, watchexec, and nodemon. Why is this posted?
