Could a desktop application disclose location even if a VPN is used?

When using a proper VPN to access a remote server, the server should not be able to resolve your country of origin using your IP address because the IP provided in the request will be the one of the proxy.

Now let’s talk about a desktop application able to run system commands: even if you use a proxy to hide your origin country, could the malicious application perform a traceroute and provide the output to the remote server, allowing it to resolve your origin country?

Traceroute was the first example coming to my mind. Any other tool/technique proving the point could be used to answer the question (except locales about languages/keyboards/etc…)

Regular Expression with at least one a, even number of b

I’ve been working on some regular expression questions, and came across one that I cannot figure out. Working on the language over $ \{a, b\}$ , the text asks for a regular expression for the language of all words having at least one a and an even number of b’s, using only | and * (maybe $ \varepsilon$ too). My idea so far has been something like $ (a^*ba^*b)^*a^*a(a^*ba^*b)^*a^*$ , but this doesn’t match cases like bab, bbbab, or baaab.

Why rounding odd font sizes to even?

Today I started implementing a design that had some copy text with font size 17px. My fellow web developer told me that we should round that to 18px. He thought that the text may look better. He was not sure of it. He said that he at his former job was told to round all odd font sizes up to even.

So my question is: do text with even font size look better than odd? Or what is the reason to round odd font sizes as given by design to even in the css?

Google says my URL is blocked by robots.txt — I don’t even have one!

I just discovered our image system domain is not being crawled by Google for a long time. The reason is that all the URLs seem to be blocked by robots.txt — but I don’t even have one.

Disclaimer: Due to some config testing, I now have a generic allow-everything robots file at the website root. I didn’t have one prior to this hour.

We run an image resizing system at a subdomain of our website. I’m getting a very weird behaviour as Search Console claims to be blocked by robots.txt, when in fact I don’t even have one in the first place.

All URLs at this subdomain give me this result when live testing them:

url unknown to google

url supposedly blocked by robots

Trying to debug the issue, I created a robots.txt at the root:

valid robots

The robots file is even already visible at search results:

robots indexed

The response headers also seem to be ok:

What should I do?

jQuery script not working even with document.ready

I’m trying to add this code to my project, the idea is when you click any post, it takes the information from the post and paste it in the popup container.

It works good when I run it from the DevTools, but when I add it to the footer from the WordPress dashboard, it doesn’t work.

The script is:

jQuery('.caja-noticia').on('click', function(){   var nombre = jQuery(this).find('.titulo-noticia').text();   var texto = jQuery(this).find('.texto-noticia').text();   var descarga = jQuery(this).find('.link-noticia').text();   var video = jQuery(this).find('iframe').attr('src');   jQuery('.videoPopup').find('iframe').attr('src',video);   jQuery('.tituloPopup').text(nombre);   jQuery('.bajadaPopup').text(texto);   jQuery('.downloadPopup').attr('href',descarga); }); 


Please if anyone knows how to fix it!

Proof with induction even number of letter

I have to proof that in a word $ w$ the number of the letter d is always even.

Let $ L \subsetneq \Sigma^*$ be a language over the alphabet $ \Sigma = \{a,b,c,d\}$ such that a word $ w$ is in $ L$ if and only if it is $ a$ or $ b$ or of the form $ w = ducvd$ where $ u$ and $ v$ are word of $ L$ .


$ dacad$ , $ ddacbdcad$ , $ dddbcbdcdbcbddcad$

I know there are three cases:

  1. $ |w| = 0$ the number of the letter d is zero and even
  2. $ |w| = 1$ and $ w = a$ or $ w = b$ same as number 1
  3. $ |w| = 5$ and $ w = ducvd$ the number of letter d is even

    I know how induction works, but I don’t know to write the base, hypothesis and step. I think it works with the length of $ w$ . Does somebody have a hint?

Haunted Heroes Pact Wizard may cause a favored spell combo to be even more broken?

I’ve been looking at the Pact Wizard archetype from Haunted Heroes Handbook and noticed a feature they pick up at 10th level that states that when metamagic feats are applied to spells learned via patron or curse, the spells are treated with a spell of one level lower with a minimum level equal to the spell’s original level).

Here’s where the problem comes in. A few patrons give Time Stop as their bonus patron spell at level 18. The spell already specifies 1d4+1 rounds for how long the spell lasts. 2 to 5 rounds is pretty crazy already. The metamagic feat that could make this spell completely broken is Extend Spell. +1 to the spell’s level, and with the aforementioned class feature, 4 to 10 rounds could get that kind of spell banned from a game table.

It goes from bad to worse when Delayed Blast Fireball comes into play. Lots of players like spamming Grease to keep opponents at bay and make them easier to hit. When you have 4 to 10 rounds to charge up that fire bomb, your GM could very well ban you from using Extend Spell in that manner.

So to elaborate on the question: does the feature even work that way for Time Stop? Or does the extend only apply to the base +1 to make a +2 and then you roll? For the sake of balance, I hope it’s the latter.
