There was an openssl update recently that caused people who were using alpine to not be able to send mail. When they tried to send, they got this message:
It’s rare, but every so often I take a real vacation. By this I mean, I take off at least a week from work, go someplace and just relax. In my case, that means riding my bike around and reading. This time, I spent just over a week in New York City. I went for the Five Boro Bike Tour and stayed to go to a friend’s reading of his play. During my trip, I ended up biking over 130 miles and read six books. I could have done more of both. It was one of the best vacations I’ve ever taken.
I got this error after I updated a website from rails3 to rails4. I spent a few days going over character sets and collations in MariaDB. It turns out that all I needed to do was to use the mysql2 gem instead of the mysql gem. I am writing this so I hopefully will remember when I do this again.
I’ve used ruby lambdas a few times, but I have to admit that I never really understood them. However, I’ve now come across a case where I have to figure them out. Here’s what I’ve found:
I put up a new website that wouldn’t allow me to login and kept giving me an error that said something like undefined method `save_without_session_maintenance’. I double-checked all my controllers and models against another site that was working fine and they all matched up. I didn’t find any bug reports for the version of Authlogic that I was using. The solution was to just deploy the app again. After that, I was able to login successfully. Weird.
We’ve been using a linux computer running samba and openldap as our primary domain controller for a windows domain for years. I absolutely love the fact that I don’t have to deal with windows and their crazy licensing. More importantly, this setup makes it easy for me to create accounts to give people access to everything in our shop. This includes windows accounts, linux accounts and website accounts.
I updated a website and changed to using svg files for our header. On our test setup, we were running RHEL7, which had a newer version of httpd than what’ on our production server, which is running RHEL5. I had to add the following to our httpd.conf file to tell it to specifically serve svg files.
I’m running a server that I recently upgraded to Centos 7. For a few months, it wouldn’t send mail and today I finally decided to do something about it. I was getting an error AUTH warning: no mechanisms. After messing around for a while, I saw this in /etc/mail/access:
I wanted to completely reformat and reinstall Yosemite on an old iMac. To do this, I needed to make something I could boot from. I got an 8gb usb flash drive and used Disk Utility to reformat it to a Mac filesystem that I called Yosemite. This disk was then mounted at /Volumes/Yosemite. I then went to the App Store and downloaded Yosemite, but cancelled the installation. This left the installer in /Applications/Install OS X Yosemite.app. Then, to make the bootable drive, I ran the following command:
About a week and a half ago, I pulled a muscle in my back. I don’t know exactly what I did, but I do remember that I was putting on a sock. I don’t remember doing anything odd, but I do remember the sharp pain. I thought it might be something bad, but I proceeded through the day as usual. I had this same injury (though much worse) about 15 years ago, if not more. At that point, it hurt so badly that I had a hard time standing up. Now, I’m pretty much ok if I keep my back bent a little, but it hurts quite a bit when trying to straighten it. This leads to the odd situation where riding my bike feels really good, but going for a walk can be painful.
Went for a nice bike ride this morning because it’s lovely out. Decided to ride to the bank to deposit a check and then take a ride along the lakefront. Did about 13 miles and felt pretty good. I just noticed on my Cyclemeter app that it tells me how many miles I biked overall last year. It’s close but I know that I don’t always remember to turn it on and I only got the app in April. So it’s probably a bit low. Anyway it says I rode 1131 miles last year. So far this year, I’ve ridden 102 miles. That’s pretty good. I didn’t think that I already rode that much this year. I think I now have a goal for the year. I need to do more than 1131 miles.
I’m not sure how I didn’t notice this before, but my deployment on an app was suddenly taking much longer that it had in the past. While I was watching it run, I noticed that when bundle install was running, it was saying installing each gem. I don’t know why I didn’t notice this before. I looked on my server and noticed that each release was about 177mb in size and the vendor/bundle directory was 173mb in size. I was reading the Bundler website when I saw this bit:
I upgraded a new app to use Rails 4.2 and bootstrap and I thought things were fine. However, when I went to the page today, css wasn’t working. It just never created the css files. Turns out that I needed to add the ‘sprockets-rails’ gem to my Gemfile because the asset pipeline is no longer a feature of rails 4. Once I ran bundle and commit this change to the repo, I could deploy and things worked fine.
I had been feeling pretty good about my Rails skills and had been able to create and deploy a number of simple applications. Since simple applications are just about all I’m going to write, I was ok with things. But I was hanging on to earlier versions of things and it was starting to bug me. One big one was the capistrano gem. I knew there were big changes between version 2 and 3, and I had a pretty good setup using version 2. However, I know that things constantly change so I decided to dive in and start using capistrano version 3, 3.4.0 to be exact.
This is the true joy of life, the being used up for a purpose recognized by yourself as a mighty one; being a force of nature instead of a feverish, selfish little clod of ailments and grievances, complaining that the world will not devote itself to making you happy.
I don’t know if it’s because I’m getting older or if we had a particularly snowy winter, but I cannot wait for spring to come. Today makes me happy because spring training starts and I can watch a game on tv and see the outdoors not covered in snow. Something that makes me even happier is that today signups open for 30 Days of Biking. This is a group that asks people to pledge to ride their bike every day in April. That’s it. The idea is that if you ride every day at the start of biking season, you’ll be more inclined to think to use the bike for small errands and things during the rest of the summer. It’s brilliant in its simplicity. It doesn’t cost a thing. The idea is just to get you out biking. And as an added bonus, they’ll donate a bike to a kid in need for every 30 riders who sign up. I did it last year with my sister and a friend and it was fun. On the day that we spent 15 hours in the car on the way back from Boston, I did have to borrow my nephew’s bike at 10:30pm to ride to the corner, but I’m happy to say that I rode every day. And it’s a great reason to get together a group and go for a group ride. So I just pledged again this morning and am looking forward to it. I’ve already ridden a bit this winter, but spring riding is so much more fun. So if anyone else wants to pledge, I say go for it! And if you’re looking for someone to go for a ride with in April (or quite frankly anytime), let me know. I’m in!
I suddenly realized how to change a boolean with a button in a much easier way that the post I did yesterday. All I did was make a form with one hidden field (the boolean that I want to change) and just show the submit button.
There’s a much easier way to do this, which I show in this post.
I have a website that I’ve been using to track timesheets for a number of people. It’s one of the first websites I wrote in rails, written about four years ago. The only person who really uses it is me, but a few other people also login to view the information. Anyway, the site was written in rails 3.2.11 and now the latest version is 4.2. I’ve decided that since I know a bit more rails now (I wouldn’t say I’m a good programmer), I’d rewrite the program. It’s not that elaborate, but it does work really well for me.
I’m very grateful to someone for posting all the episodes of The Secret Life of Machines online. I LOVED this show when it was first on. A while back I actually looked to buy a dvd of the shows and couldn’t find it. This makes me so happy!
At work, we have a bunch of computers running linux and hosting disks that are shared using NFS. Of late, many people have been switching to Macs as their primary computer. Usually, they then just ssh into one of the linux machines and work as before. However, now I think they’d like to be able to stay on their Mac and still access the files in linux. Macs are unix-based, so mounting NFS drives isn’t that much of a problem. However, the default user ID and group ID used on the Mac does not match up with our uids and gids in linux. The default (first) user on a mac, is give UserId = 501 and GroupID = 20. This group id corresponds to the group named staff. I wanted to change these ids so they match up with the ids we use in linux. Then, when the user creates a file on an NFS drive, they’ll have the correct owner and group. How to do this? The dscl command on the mac is the one to use.
We had a bit of a storm here yesterday.
One thing I have learned is that you can’t have too many clamps. I basically had enough to work on one board at a time, which means I’d have to wait for one board to dry before doing another one. Since I’m hoping to eventually build something in my lifetime, that was too slow. So I went to the store and bought another eight clamps. I seem to need 7-8 clamps per board. Now I can work on two at a time. Pictured below are the boards that I’d like to use for the sides of the bookcase I want to build. One is basically done and the other needs some more lathe. I’m out of what I’ve already sanded, so it will have to wait until I prep more boards.
I thought I should try to fix the holes in the one board I made the other day. My idea was to mix up a bunch of glue and sawdust. Then try to fill and cover all the holes with this mixture. Here’s how the board looked after I filled them all in. I wasn’t too careful about making it smooth because I knew that I’d have to run it through the planer again to smooth it.
Here are all the boards I’ve made. The first is at the top, second in the middle and the last one at the bottom.
