I wanted to create a table of contents from the post's heading tags automatically without having to change the headings like adding an id or anchor. I started to look at existing solutions and came across this custom function on Stackoverflow by sjaak-wish function generateIndex($html) { preg_match_all('/<h([1-6])*[^>]*>(.*?)</h[1-6]>/',$html,$matches); $index = "<ul>"; $prev = 2; foreach ($matches[0] as $i => $match){ $curr = ...

I'm struggling to understand a behavior I can't explain in a sample network. Basically I want to be able to switch some of my servers by redirecting to a different server (so that I can point my applications to some database server for example and then switch the database connections to another server without changing the applications). I'm probably going to use something like rinetd for that, but I'm curious why some iptables rules are not working as I would expect. The sample network had 3 ser...

Typically I'm using MikroTik embeded routers, they're basing on Linux so their firewall settings feel pretty much 1:1 the same as iptables, just commands are a bit different but mechanics the same. Some more advance MTK firewall functionality with raw iptables can be achieved using -m extensions - like connection states or comments for example. I can't find disable option in raw iptables. Is there any iptables extension that allows to temporarily disable iptables rules? By temporarily I mean dis...

On my iPhone, there is an app for Google Inbox, where I can swipe messages left or right to archive them or snooze them. Is there a way to get the web version to do the same thing on a touchscreen computer?

Since I have upgraded Windows 7 Pro to Windows 10 Pro, I notice that Windows would appear unstable immediately after unlocking. It doesn't happen right after a very recent restart, however as time passes by (I normally put it to sleep every evening and leave it running but locked during the day), it get progressively worse. At first, nothing out of ordinary happens - unlock the computer and everything is just the way you left it. Next day, after a night of sleeping, things start to flicker just ...

I have a Samsung S7 for which I bought a 200GB microSD card. I formatted it as adoptable storage (using an adb shell workaround because Samsung has actually disabled the Marshmallow feature by default). Now, I can store all manner of things on it, including about 17GB of music which I manually copied over. However, I want to use DoubleTwist Sync as I have lots of iTunes playlists that don't get copied over when manually copying files. I installed both the DoubleTwist PC app as well as the Androi...

PEiD states that if I choose to unpack the Delphi file that it will execute the file, obviously I don't want t...
