Recently I rebuilt my personal mail server (and Mailman list server) on a new version of Ubuntu. Everything went well and the Mailman list worked fine, except that all of the CGI-BIN scripts would download in the browser, rather than executing. I spent a lot of time troubleshooting this issue, making various changes to my Mailman configuration, all to no avail. Eventually, I gave up and just let it sit...mail was working, so it wasn't an emergency. However, this weekend I decided I needed the interface working, so I dove back into troubleshooting the problem and looking for answers. I again made several changes to the configuration, tweaking ScriptAlias and whatnot, again to no avail. Then I stumbled upon...

I recently installed Fail2Ban on my personal mail/web host as the number of "bad actors" has climbed a lot in recent years and I no longer felt comfortable just allowing them to pummel my server. I'm writing up another blog post shortly on everything I did and how it all works; however, I had one issue that kept cropping up: Running fail2ban-client status recidive returned the following: Status for the jail: recidive |- Filter | |- Currently failed: 158 | |- Total failed: 741 | `- File list: /var/log/fail2ban.log `- Actions |- Currently banned: 8 |- Total banned: 8 `- Banned IP list: 185.127.19.155 203.87.129.135 80.82.77.203 94.102....

It's spring here in Silicon Valley and that means it's time for the Apple World Wide Developers Conference (WWDC). This year did not disappoint with Apple making not 1, not 2, but 6 major announcements: tvOS, now with Amazon Prime Video watchOS 4, Siri and Toy Story watch faces Mac macOS High Sierra (no it wasn't a joke) iMac speed bumps MacBook / MacBook Pro speed bumps New iMac Pro iPad Pro 10.5" (and updated 12") iOS 11 HomePod (Siri-powered Speaker Assistant) These are some great announcements from Apple, but what I'm most excited about are the announcements that were behind the announcements.

I recently decided to run Kali Linux on my MacBook. I originally thought I'd just build it into a Virtual Machine (using Parallels), but was concerned that I might not have the control over the hardware that I'd need in order to make Kali effective as a learning environment. So, I set about working on a dual-boot scenario. Needless to say, I failed miserably when I opted to have Kali install Grub and it overwrote my primary Boot Manager on the Mac and rendered the system unbootable (and eventually unrecoverable). Thank goodness for good backups... WARNING: Do not proceed with any of these steps unless you have the ability to restore a bare-metal backup. Everything I'm doing has the potential...

I recently listened to Triangulation episode #278 with Tim Wu, author of The Attention Merchants (which I'm currently reading). Tim, and Leo, both stated in the podcast that getting people to pay for content is hard, which is why advertising supported content is so prevalent. Here's some of the content I willingly pay to consume: Apple Music ($14.99 / month) - Ad Free* Apple Match ($29.99 / year) - Ad Free AT&T U-verse (just the television portion, $90/month) DirecTV Now ($35/month) Audible Membership ($16/month) - Ad Free* iTunes Movies (we own over 100 titles, including Top Gun) Washington Post New York Times MacLife Consumer Reports Popular Mechanics Simple Habit (Meditation) AllTrails (Hiking Trail Maps) Hulu...
