    So tape doesn’t make sense for the typical person, unless you don’t have to buy the equipment and store i.

    But, if you’re even a small company it becomes cheaper to use tape.

    Companies don’t like deleting data. Ever. In fact some industries have laws that say they can’t delete data.

    For example, the company I work in is small, but old. Our accounting department alone requires complex automated processes to do things each day that require data to be backed up.

    From the beginning of time. I shit you not. There is no compression even.

    And at the drop of a hat, the IT dept needs to be able to implement a backup from any time in the past. Although this almost never happens outside of the current pay cycle, they need to have the option available.

    The best way they have to facilitate this (I hate it - like I said they’re old) is to simply write everything multiple times a night. And it’s everything since we started using digital storage. Yes, it’s overkill and makes no sense, but that’s the way it is for us. And that’s the way it is for a lot of companies.

    So, when we’re talking about that amount of data, and tape having a storage cost advantage of 4:1 over disk, it more than pays for all the overhead for enterprise level backups.






  • Watch a Video or read something because it really is an invaluable tool. But here’s a crash course:

    Debuggers, or IDEs, let you step through your code in slo-mo so you can see what is happening.

    1. Set a breakpoint - Click to the left of a line of code so a red dot appears. Run your program, and the IDE will execute to that line, then pause.
    2. Look at variables’ values - While the execution is paused you can hover over variables before that line to see their value.
    3. Step through the code - See what happens next in slo-mo.
      • Use “Step Into” to enter into a function and see what that code does.
      • Use “Step Over” to not go into a function and continue in the current spot after the function has done its business.
      • Use “Step Out” to exit a function and pick up the execution after it has run. Use this when you’re in too deep and the code stops making sense.
    4. See whats in the heap - The heap will list all the functions that you’re currently inside of. You can jump to any of those points by clicking them.
    5. Set a watch - Keep a variable in the watch so you can see what its value is at all times.
    6. Set a condition on the breakpoint - If the breakpoint is inside a big loop, you can right-click on the red dot to create a conditional breakpoint, so you write something like x===3 and it will only pause when x is 3.

    There are many other things an IDE can do to help you, so def look into it more if you want to save yourself a lot of insanity. But this is a good starting point.

    If you’re developing for the web use F12 to open web tools, and when an error happens, click the file/line number to see that point in the Sources tab, and you can debug there.


  • Many years ago - many jobs ago, we got a new CEO, and she wanted to make a big splash, so she started firing people. And this is a public, non-profit job, so most people were working in less than stellar conditions simply because they were passionate about public service.

    I was two days away from putting in my 2 weeks’ notice because I had landed another job, but they fired me and gave me two months’ severage. So instead of having to work another 2 weeks, I didn’t have to go another day. I said “Sorry it didn’t work out.” and held my smile till I got out the door.


  • I just saw this tik-tok that proposed that when Carmen hit the asteroid, it sent the asteroid on a new trajectory.

    And that was the asteroid that started the war between humanity and the bugs - that the military spun it into a story to get humanity invested in the war.

    Now, it’s been forever since I’ve seen the movie, but I vaguely remember the war already going on by the time they were in the academy, so I don’t think this could possibly be true, but I love fan theories like this.
