    1. A common misconception is that the risk of overfitting increases with the number of parameters in the model. In reality, a single parameter suffices to fit most datasets

      For almost a year now I have been playing D&D, loving every moment we get together and have a session. Because of life and stuff it's been a once a month meet up and the current campaign is coming to an end.

      For the better part of all that time I've sat staring at an un-painted mini, I finally took the next step and got a stater kit of paints and went at it. I wish I had done this sooner! So far they are rough as hell but honestly it's such an enjoyable little hobby. I plan on expanding my paints out to more technical washes and shades and with that buying any mini that looks fun to paint.

      I know a few folks play table top games. How many of you paint as well?

      Currently there are 2 confirmed dead and 4 injured, 3 of who are in critical condition. The shooter is in custody and police are currently sweeping the buildings.

      I can see the helicopters from my dorm.

      Some news articles:

      Update: The campus is still on lockdown while the rest of the buildings are cleared. A candlelight vigil has been planned for May 1 (tomorrow) at 6 PM.

      Update 2: Today was the last day of classes, with exams starting Thursday. All exams before next Sunday will be canceled (not sure if they'll be rescheduled yet).

      Update 3: As of 5:20 AM, the lockdown has been lifted and campus is all clear. The names of the injured have been released.

      The shooter has been charged with:

      • 4 counts of attempted first degree murder

      • 4 counts of assault with a deadly weapon inflicting serious injury

      • 1 count of discharge of a firearm on education property

      • 1 count of possession of a gun on educational property

      • 2 counts of murder (they did not specify which degree)

      All of these are felony charges.

      It should be noted that the shooter was arrested before he even had the chance to leave the classroom. That was an extremely fast police response.

      Edit 4: Due to exams being cancelled through Sunday, all exams are now optional. Looks like I might only have to worry about 1 final now.

    4. What is, in your opinion, missing on Tildes?

      Pretty much the title. What do you think is missing on tildes? What is something that you'd like to see on tildes that is currently lacking? It could be discussion wise, a feature, or anything...

    5. Markdown preview is now available when writing topics/comments/etc.

      Continuing to work my way through (long overdue) merging of open-source contributions, today we've got another much-requested one that was implemented by @wirelyre: a preview function for markdown.

      Anywhere that you're writing markdown now (comments, topics, messages, user bio), there will be two "tabs" above the text field for "Edit" and "Preview". You can flip back and forth between them to see what the result of your markdown will be while you're writing, which should make it a lot easier to work on some of the tricky formatting like tables.

      Like so many other features, there are still a few little weird interface oddities with it, but I wanted to get it live on the site and will probably do a few more minor tweaks to it today. Let me know if you notice anything particularly strange or broken with it.

      And thanks again, @wirelyre!
