My understanding:

A VIX future contract says Alice pays Bob cash up front for a contract, then Bob pays Alice cash on a specific date in the future based on the VIX value on that day, how much depends on a formula based on how low/high the VIX is.

The VIX itself is just a number calculated from recent S&P trading prices. The formula that determines how much Alice gets back in different scenarios is the main thing that makes different VIX futures contracts different. The formula can be "long," which means positive slope (higher VIX = Alice gets more) or "short" which means negative slope (higher VIX = Alice gets less). The formula can be "leveraged" which means slope greater than 1 (higher leverage = Alice gains or loses more per unit change in VIX).

Alice is called the "party" and Bob's called the "counterparty." A modern futures market has a small set of standardized contracts and a settlement / clearing system which allows anyone with a brokerage and enough money to act as a party or counterparty.

So the ETF basically takes investors' cash and buys a bunch of futures, which could all be from a bunch of different counterparties. The counterparties for the short futures have been losing money (paying more out at the end of each contract than they got at the beginning), which is where the money the ETF investors have been making up until now comes from (the numbers work out so that Bob was paying Alice more than Alice paid Bob). But this time the counterparties are making money (Bob pays Alice less at the end than Alice paid Bob at the beginning).

Because of leverage, in the worst case Alice could lose most or all of the money she put into the futures contract. Because this ETF's purpose is to put all of its investors' money into this futures contract, if you invested in this ETF you were making money before, but now you've lost nearly all of it.

Huh I was just saying Baltimore is not a bad city especially if these negative stories paint a different picture and in ones mind not a positive one.

Thus, I was pointing out positive aspects of this city that are available to everyone!

As for being privileged I am not rich nor have parents that are wealthy rather about middle class. My startups I started and made no money off we’re all paid for by myself from savings or grants I received from incubators. Thus anyone who wants to can work hard .. save money .. do a startup to either hit the jackpot or use the experience to learn an on demand skill.

I am no way making 120 to 250k in Govt IT but know friends who are after ten or more years. Maybe I will one day and if so that would be great .. though it would come after years of hard work.

I think the internet-model just isn't created for in-depth, thought provoking, long form articles. I am lucky enough to live in a major city, but I consume thought provoking, free content by having a library card.

Of the publications where I found thought provoking, long form articles, they are almost always a non-profit. The internet ad-based business model for content simply forbids huge ROI for real content; I totally support more-and-more non-profit content creators whose charter is quality content.

If you are interested in non-hobby, free long form writing, I always recommend Aeon[1]! For non-free, I recommend Lapham's Quarterly[2].

Since Sciter was mentioned, I'll probably mention https://github.com/zserge/webview which is a thin wrapper over native browser engines (webviews) and allows to bind HTML/CSS UI to the native code. It results in fairly small executables, and works well with C/C++/Go or there are some 3rd-party Rust or Nim bindings.
Have you considered charging 20%? Think of the value you'd be forced to provide! :)

In all seriousness, this is a good attitude to have, except that switching from you guys to someone else is going to be genuinely painful. The provider I use now has an API and provides full CSV and JSON exports of everything, and then all the actual payments live in Stripe. Switching should be a snap, right?

But it's still a pain to migrate over the user accounts, force users to reset their logins, setup new subscriptions with the same different billing amounts (prices have changed over time), discount codes, and billing dates, ensure that everything continues smoothly so I keep getting my money, switch over all the integration points with my site and analytics, etc, etc, etc.

It's such a pain to switch that many just won't bother to pay that big upfront cost in order to save money every month going forward and will just put it off, which is why I find this pricing model to be particularly aggravating. They wouldn't have signed up for it in the first place had they known, but they didn't know and now they're "trapped".

I hope you're just underestimating the difficult of switching away and not counting on it!

I completely agree with you. Unfortunately, legislation has been stuck in the 80's for the most part, and while I understand why, it can be frustrating.
Momentum Gathers for Persistent Memory Preppers
TLDR, a bunch of people lost their money placing a bet on a number that comes out of a complicated formula involving stock prices.

The article's handwringing because their number might have included "novice retail investors" who didn't understand what they were buying, and only bought it because it's been a winning bet for a while.

If you don't fully understand a financial or investment product, you shouldn't buy it. Financial products involving words like "leveraged" or "options" or "cash-settled futures" are quite often more like bets than investments, and you should only trade them if you fully understand the product you're trading and are willing to accept that losing the bet may mean losing all the money you put in.

What pisses people off is how spez (reddit's CEO) is dancing around the fact that for a reason or another he can't/doesn't just punish a misbehaving subreddit while other borderline subreddits otherwise very cooperative but way smaller get shut down regularily.

It's a bit like how kids in a class get away with sticking gums two or three times on their desks "because they were quick to remove it" when other kids have their parents called the first time they bring a circuit board to school.

Reddit does what it wants, that's their platform. It just looks terrible on the face of it.

Kotlin would do what they call a 'smartcast' : ie if you did an instanceof if the if, in the corresponding {}closure you know the type of this object.

The whole code is probably unmaintanable for anybody other than it's original writer (and even for him, there must be a limit to how much code you can fit in your head).

I would love to work for Telegram, it is one of the products I use daily .. but if I had to handle this codebase, it would be a rare case of 'total rewrite or I am out'.

Incidentally, it looks like they are going to do this full rewrite. Telegram seems to have acqui-hired the creators of Telegram X and are prepping it up as a replacement.

You would prefer they charged you more or reduced your features?
I doubt clothing could be a full human language. A human language is a remarkable thing. Our language ability is one of our chief adaptations as a species, with it I can conjour the precise and bizarre notion of a purple bus-driver giraffe with those few mere phenoms.

I would imagine we must have some systems for interpreting information about other humans from their accoutrements, but I would also imagine that they surely cannot be as highly developed as our language, as the technology to have different 'styles' or even clothes at all is relatively recent. Also as a bit of anecdotal evidence I present that, any healthy human growing up around at least one other human will develop a spoken language, or adopt the language of their peers. In contract there are examples of people growing up in societies with clothes and style who do not develop any particular style sense.

So I posit that this style language is relatively limited and only certain pre-arranged messages determined by society can be communicated by it. Also it seems extremely prone to misinterpretation . Both parties must be aware of, and agree on, the pre-arranged signals for it to work.

Which is why I personally dont even consider it. With such a limited and error prone language how could I accurately communicate anything meaningful, or personal, or that I particularly value, about myself. Also why would I would I want to blast out this signal to all and sundry?

Barlow's Declaration of the Independence of Cyberspace [0] is one of the quintessential works that made the web the free place it is. What a great loss.

As a teenager, Barlow's writings inspired me and many others to do things such as paint our websites black to protest the Communications Decency Act, and write lots of actual letters which, in aggregate, effected change legally and socially.

In 2000 at Comdex, I remember Barlow saying that he had no love for the record companies - as a member of the Grateful Dead he had never received a royalty statement that didn't say he owed the company money. This was during the height of the war on MP3s when other artists were claiming they were being robbed at gunpoint or something.

Here's a link to his "A Declaration of the Independence of Cyberspace" from 1996, published 22 years ago tomorrow:

https://www.eff.org/cyberspace-independence

I always loved these bits:

"Cyberspace consists of transactions, relationships, and thought itself, arrayed like a standing wave in the web of our communications."

And:

"Your increasingly obsolete information industries would perpetuate themselves by proposing laws, in America and elsewhere, that claim to own speech itself throughout the world. These laws would declare ideas to be another industrial product, no more noble than pig iron. In our world, whatever the human mind may create can be reproduced and distributed infinitely at no cost. The global conveyance of thought no longer requires your factories to accomplish."

RIP.
Tesla announces biggest quarterly loss
At the key-value level, CockroachDB starts off with a single, empty range (a set of sorted, contiguous data from your cluster). As you put data in, this single range eventually reaches a threshold size (64MB by default). When that happens, the data splits into two ranges, each again covering a contiguous segment of the entire key-value space. This process continues indefinitely; as new data flows in, existing ranges continue to split into new ranges, aiming to keep a relatively small and consistent range size. Each range is replicated 3-way (by default) as well, and is backed by a single Raft instance.

When your cluster spans multiple nodes (physical machines, virtual machines, or containers), newly split ranges (or more specifically, replicas of these ranges) are automatically rebalanced to nodes with more capacity. Writes addressed to a range are handled by the Raft leader for that range (which can hop around its various replicas as needed). Writes to different ranges (non-overlapping key spaces by definition) are processed independently, and very well may be processed across multiple machines.

A long time ago, I discovered that a nearby neighbor had a beautiful Mercedes limo from the 50's in his garage. I asked him about it, and he said he had restored it. I asked him how he dealt with acquiring parts that were no longer available.

He replied: "Oh, I made them."

Me: "What...."

So he showed me his full sized basement, which was a fully equipped machine shop. He'd built working steam locomotives that were several feet long, and other mechanical models, all working, all from scratch.

I was amazed. I asked him what the Mercedes was worth, and he replied, and I remarked that it couldn't be worth all his labor he put into machine work. He agreed, and said it was his hobby and evidently made him happy.

These days, of course, you can just make a drawing of what you need and send it to one of those online machine shops.
Promenet, Inc | NYC Onsite work | $50-60k (Junior Engineer)

Is anyone looking for an IT / Security job?

I came from more of a background in software development and found my way into networking. I found huge differences between them. I think they involves two very different mindsets.

Networking is great for people who are very interested in learning how to operate things. They want to get to know how to use things in the world to their advantage and find ways to make them do useful things in concert.

A programmer has to think more about how to get new, undiscovered or previously unimplemented behavior out of a system and do so reliably.

Network engineers need to do that at a large scale as a small aspect - like when a network goes completely down and no one knows why. You have to discover how things are supposed to work, why they're not working, and how to get them to work again - that's support. They also have to be able to design at a large scale and understand pre-built connection templates (i.e. protocols) and follow them. And they need to be responsible for hundreds of customers access to information, utilities, and the business.

We look for engineers with college degrees in sciences and technology. Promenet has 20 years of experience, with focuses in security, networking, systems, consulting, infrastructure managed services, and other high-level IT services. Named CRN Pioneer 250 for MSP 5 years running. Servicing 85% of New York private schools, and many businesses in legal, finance, insurance, and more.

I guess the point is that you can get away with such sloppy code as long as it is a solo project of a relatively small size.

I am not sure at which point it becomes too big and new features and bugs are just impossible to handle.

It might have been the right choice for Telegram though. Their app feels snappy, so the 'only' big downside is that now it looks like they are going to have to thrown away this entire code base and replace it with the one from Telegram X (a third party client they bought)
