Project Euler Forum

Solving problems can be quite addictive and when a mass of "easy" problems lie in-front of you the temptation is to solve the next, solve the next, and so on, until you can't solve any more. Sorry if you've already done this, but there is a mass of learning that can be found in the threads of the pr...

Sorry for the very slow replies to these requests. I've added GDScript, Elm, and PureScript. Alas! Visual BASIC is still just BASIC when it comes to solving Project Euler problems and the fundamental paradigm in which it is defined. The Visual element does not add anything different in this respect ...

Sorry for taking so long to check back. That actually did the trick. No matter. I'm grateful that you did get back and let me know that it's working for you again. It is strange that you never experienced the same problem elsewhere, but it does make me slightly suspect of what that extension is doi...

@Nacnud: Can I ask... are you able to sign-out? Signing out uses the same token principle as answer submissions and modifying details on your account page, except the hashed token is sent via the URL rather than posting through the HTML form. If you are able to sign-out, then the issue is definitely...

@Nacnud: Thank you for the very detailed feedback. It'd be good to know what that torrent scanner was doing that would cause the issue. I keep revisiting the code and testing it and I'm unable to reproduce the issue on my local machine in Chrome (or Firefox). In complete desperation, the only other ...

I really appreciate you taking the time to try thing out, but sadly I'm not getting any closer. I imagine it's also impossible for you to sign out using the Sign Out link in the menu bar too? Those errors you're seeing should only happen if the one-time token is not being validated. It is common pra...

Good spot, pjt33. That information (the answer) is not available now from where the problem data is retrieved, so, as you suggested, I've removed that line from the first post. Thank you for pointing it out.

Nevertheless, I suppose you would be interested in getting to the bottom of this error. Absolutely, and you certainly should not have to use a different browser. What is confounding me is that when I use the latest version of Chrome, I don't see the error. I can leave the page inactive for twenty m...

Thanks for getting back. This is growing into a greater mystery. I use Firefox myself, but I test in other browsers and I'm unable to replicate the problem using the same version of Chrome you gave. It is common practice with modern sites to have each page involving a submission generating a hashed ...

Hi Jevoux, and welcome. This should not happen at all. Did this happen once or has it happened more than once? The answer submission page is using the exact same system that allows you to modify your account details, so if the answer submission is not working, then I imagine you cannot change any of...

That's very useful feedback. Thank you.

You should not have received a 30 second warning if the page had expired. I've modified the script and that shouldn't happen again.

Yes, it is quite intentional. Most users will rarely see the CAPTCHA now, but it will appear for a period of time if the system detects unusual patterns.

@nida78: It means a lot to the team when members, like you, recognise how much we value the problems that we have created and what can be gained by first solving the problem for yourself. It is disappointing that a small number of people have chosen to deliberately and thoughtlessly spoil many of th...

Thanks for reporting it. They are both unrelated issues. The pinning/unpinning problem has now been fixed. The accessibility issue to this forum: Open or Save dialogue appearing, is still going on. I have been made aware of it twice in the past two days and I'm waiting for our hosts to get back on t...

I've just tested it in Firefox and Chrome and it accepted the correct answer in both browsers without any issues. If it might spoil something sharing it here and you think you know why it was happening for you, then feel free to send me a PM.

Not a problem. I just glad you managed to sort it for your own peace of mind.

I'm not sure about why Chrome is doing that. I've noticed it and Firefox doing it with me on different sites and it doesn't seem to be consistent. Perhaps someone reading your post might be able to offer some insights?

We don't delete accounts, so you must have registered with a different username. I've checked other usernames with 4406 in them and there are a few, but the only one to have solved more than one problem has solved 15 problems. I also checked a DB archive from some time ago and there is no user calle...

Accounts are entirely anonymous. You did not create an emergency account recovery key, so technically there is no way to retrieve your account.

I've sent you a PM.

The statement was still true: In England the currency is made up of..., but you're absolutely right. It is the currency of all four countries within the UK. I've changed the wording to reflect that. Thanks for pointing it.

@philiplu: Nice idea. I finally got around to implementing it. And thanks for the reminder, @youth4ever. I've added two related awards: Difficulty Explorer : Solve at least one problem at ten different difficulty levels Conquering Difficulties Solve at least one problem at all of the difficulty levels
