I agree, and if i were in your shoes I would want the same.

We used to have user deletes turned off for this very reason. People were deleting accounts and had no idea it was permanent and irreversible (even though the user is warned as such when they do it). So we turned it off and required users to request deletion from us just so we can press the point that once this is done there is no coming back.

However many users complained as they felt this violated their right to delete their user without moderator intervention, and they had a point. So we re-enabled it.

It is kind of a loose-loose situation for people like yourself as it is unrecoverable should you change your mind. That is one reason I suggest the whole hashed-email approach as a way for users to recover deleted accounts. But thats not how things are coded up at the moment.

@faydin

I'll do my best but as hans points out if email address data is wiped it may be a security issue too, im not sure if its even possible yet regardless. I will let you know.

At the very least you can open an account with a new username correct?

@hansw@mastodon.social @Gargron

@hansw@mastodon.social

I dont think the user wants or intends for all his data to be retained, if it was I'd agree that is an issue. I think he just wants his username back and a fresh account.

@Gargron @faydin

@hansw@mastodon.social

I dont know if this is actually how it is handled, but this is what I would do if i was coding mastodon to address both these concerns...

Upon the deletion of an account all data including email is wiped. Though the username remains reserved. But the email is replaced with a one-way crytographic hash of the email. So the email cant be recovered directly. Then if someone wants to register the same username they can if and only if their email, once hashed, matches the hash on file.

@Gargron @faydin

@hansw@mastodon.social

I agree, I would have to reconfirm they have the same email and I do not know if that information is even retained (I do not see that or any info about the user after a delete in the interface).

As far as I can tell all data is deleted, at least the data I can see as an admin. I dont know about the physical database.

With that said if all the data is deleted, including the username, then you'd be correct in the security issue and my inability to verify this is the same user, which is a valid concern.

@Gargron @faydin

@Gargron Hi gargron, hope your well.

A user of mine who deleted an account asked me to undelete it as they want to come back and have the same username.

When I looked it up on the internet it seems tootctl can technically do it but people warned it could corrupt the database.

Do you know the safest and easiest way to do this, if it is doable at all?

Imagine being so upset over a drawing that you ask people to DDoS instances over it...

Help! From anyone interested in English, Physics, Math, or Science.

I have written a rather massive article in the hopes of teaching people with mid-level knowledge in electronics about the idea of Duals in mathematics, how that applies to circuits and the various types of circuit duals that exist

I also include a great deal of detail in the end about one very obscure and rarely studied circuit dual called the magnetic circuit dual, it is a circuit, like a magnetic circuit, but instead of current being the flow of electrons, it is the flow of a magnetic field through wires made of iron instead of copper.

I even touch on briefly how one can extract energy from permanent magnets and other details most people arent very familiar with.

The problem is the article is massive and I really could use some eyes on it. Whether its just to try to help me catch english mistakes, or if your not that experienced perhaps tell me the parts that are confusing, as I would like this to be accessible to people who may not be scientists and only know entry level electronics or science. any feedback from anyone at any level would be highly appreciated.

Keep in mind I couldn't find many good sources laying out the equations for magnetic circuits very clearly so I had to derive a lot of the equations myself, though the concept is well established as fact and many peer-reviewed papers have been written on it. But bear in mind there may be minor errors in my math as well, so that too needs some criticism, though the math should be fairly close to correct.

Anyway any input from anyone would be much appreciated.

The draft of the article can be found on the beta site for my blog, here is a direct link:

Similarly if you find any mistakes you can message me here, or you can leave a merge request on the repo for the article, here is the direct link to the markdown file in the source for my blog:

It is much prefered that if you have specific edits like english or math you do it as a pull request as it can be a huge pain for me to hunt down the specific part of the text you are referring to if you point out mistakes as replies here. However if your unwilling to do a merge request please still ping me here as I'd rather know than to just let it go unnoticed.

Anyone who helps I will add a thank you with your name and a link to your own site at the bottom of the article if you wish, this might help draw some traffic to your own site.

I have been writing a blog article that is getting so big its a small text book at this point. Easily the biggest and more detailed blog article on a subject I have ever wrote.

The topic is Duals of Electrical circuits.

It takes me half the paper to even get to electronics, I start by trying to describe what a dual is in general terms, give simple mathematical examples, then go onto duals of systems of equations where I finally tie it into electrical circuits.

At that point I dive into a series of examples of different types of duals for electrical circuits, and then finally end with describing a magnetic circuit as a dual for an electric circuit, where the power sources become magnets, the copper wires are replaced with iron ones, electrical current is replaced with magnetic current (which is a propagating magnetic field), and then I explain each magnetic dual for each discrete component like capacitors, inductors, resistors, and transformers. Needless to say this thing gets really deep really fast.

If your interested in seeing the final result keep an eye out on my blog, should be released any day now.

@pthenq1 That is the name "Interactive Brokers"

@pthenq1 Yes, I use interactive brokers as my broker which provides an API to automate the process.

@Demosthenes too early to give a difinitive answer yet. It has only fully went up a few days ago in its current form and hasnt built out a full portfolio yet (most of the money is sitting as cash as it it is waiting for the right time to buy). So as of yet ill refrain from claiming any success or failure.

I have it playing with about a million dollars in terms of the total account value, but only 5% of the value of the account is existing as equity (stocks) so far. so any gains and losses are very small compared to what it will be once there is a completed portfolio at play.

As an Algorithmic Day Trader I feel kinda like I am playing one of those idle games where all you have to do to level up is sign on one a day and hit a few buttons.

@bonifartius Thats actually a conversation me and the team has discussed many times for things that might go beyond just OpenCL in the future and lead to all sorts of cool tech.

@bonifartius its definately a lot nicer than Cuda C or opencl..

Odd part is writing the project didnt prevent me from having to touch C.. the project actually looks at the java bytecode, and reverse engineers it into opencl at runtime and then compiles it... You think writing OpenCL is a pain in the ass, try writing a program that writes it for you AND reverse engineers bytecode at the same time :)

@bonifartius Only thing i find annoying about it is that it is in Java, which is a great language just not very fun. But as the main developer I realized that Java is really better suited for this solution than most other languages anyway.

Yay, this week I spoke to official devs on the Ubuntu and Debian project and it seems my Aparapi Library will be in both mainline Debian and Ubuntu package managers soon!
