Today I released version 2.0 of the List Authors WordPress widget. The underlying code has in fact existed for quite some time in the form of a patch submitted to WordPress to enhance the abilities of the wp_list_authors template tag. My hope was that the patch would make it into version 3.0 of WP after which I could update my widget to use it. That never happened so I have instead added a custom version of the wp_list_authors function to List Authors plugin.
After several months of tweaking and re-tweaking my patch in response to comments from various WP devs, I was confident that the patch was production-ready. The feature request has been open for over a year with a working patch for six months–at this point, I doubt it will ever be released. Maybe there are legitimate performance concerns with the patch (there aren’t any problems I’m aware of), or maybe the features are just too low in priority. The patch was my attempt at contributing back to an open-source project. After this experience, I have to say I’m a bit disappointed in the whole process. Maybe I’ll try my hand at it again, but it will be with a project other than WordPress.
In the meantime, I hope those using my List Authors widget enjoy the new features of version 2.0.
My plan to create a PHP/MySQL implementation of my PhotoNotes script was completed sooner than expected thanks to the requests and encouragement I’ve received on the project page. This was the perfect opportunity for me to teach myself some AJAX: creating, updating, and deleting notes all happens without a page reload.
Better error handling is something I will work on in a future release. Right now, the user will not see any errors occurring from the PHP script. This is an area that needs to mature for AJAX in general. I skipped through a couple AJAX books at the book store and one didn’t even have the word “error” or “exception” in the table of contents!
p>It has been an exciting and hectic month to say the least. Talisha and I had our 3 year anniversary dinner on February 3 at La Belle Vie. I’ve known for some time that she is the perfect girl for me–Talisha truly understands me, has a great sense of humor (because it’s like mine) ;), is a loving and caring person, and is in every way gorgeous to boot. My proposal to her was long overdue but I wanted to make sure it was special and memorable! In my head, this meant a romantic moment during a trip somewhere exotic but, with our vacations being few and far between of late, I had to make do. On our anniversary night at a fancy restaurant, however, “make do” is the wrong term to use.
I did my best to not act nervous during dinner. There was no doubt that I was popping the question that night because I had planned ahead of time to have the waiter bring out the engagement ring with the dessert. When the moment came, I was a little too eager to drop down on my knee–Tally hadn’t even had time to notice the ring on the dessert plate! I did achieve my goal of completely surprising her, however.
Now, the fun of wedding planning begins. What’s the date, budget, where, who to invite, what food and beverages, what kind of invites, etc, etc, etc? It’s so overwhelming that I’m almost avoiding thinking about it until I finish planning our road trip (more to come on that) and begin my job at St. Thomas in a couple of weeks.
That’s right, after almost four years at Cargill I am moving on. It has truly been an awesome and valuable experience at my current company and I am sorry to be leaving. I will especially miss my coworkers but hope to stay in touch with them. A few weeks ago, I interviewed with the University of St. Thomas for a web developer position. Those who know me will also know that web development is a passion of mine that I’ve had at least since high school. Although I have kept current through side projects like developing a WordPress plugin, the range of web technologies that I could learn Tutuapp APK about and work with has been limited for the last couple of years. When I was offered the UST position, I couldn’t pass up the opportunity to get back into the field. Another huge consideration was the generous tuition remission for myself and Talisha because getting back into school is very important to both of us. My final day at Cargill is next Friday and I will start my new job the following Monday.
My next coding side-project is another WordPress plugin. After posting some photos of my breadboard, I decided it would be nice to have a way to add notes to those photos. The current solution is Mbedr which I’m not happy with because it requires that the photos be hosted on Flickr and makes a call to Mbedr’s web server.
Take a look at the PhotoNotes project page to see my progress so far. It’s not yet saving any changes to the database but having some working display code means that I’m half way there.
As can be seen by some of the comments left on the site, a couple of frequently requested features cannot be added to the List Authors widget because they are not supported by the underlying wp_list_authors template tag. The WordPress code for wp_list_authors needs to be changed to enable these new features.
Feature 1: Allow an upper limit to the number of authors listed. Some WordPress sites have hundreds or even thousands of contributors. wp_list_authors currently would list all of them and, worse, execute an SQL statement for each author. The proposed fix could be a non-negative integer option named “count_limit.”
Feature 2: Allow sorting of the author list. This could be an option named “sort_by” with the values “name” and “post_count.”
Today I submitted a patch to WordPress Trac including both of the above features. It also changes the code to use a JOIN statement to get the author post count instead of running an SQL statement for every author. This was a necessity to prevent inconsistencies when applying the LIMIT and ORDER BY. One of the core developers is reviewing it now and, if I’m lucky, the change will be included in the next major release (version 3.0). If that happens, you can be sure I will be updating the List Authors widget to make use of the new options.
A less frequent request but one I’ve seen is for an “exclude” option with the ability to filter out certain categories of authors. There is a separate ticket for this and I might consider submitting a patch for this next.
I actually started this a couple of months back, but now that I have something working to the point where I’m pretty excited about it, I’m ready to share my pet project. Back in college, one of my favorite classes was my small electronics class. Learning about half-adders and resistors was okay but the really fun part was using embedded programming to interface a micro-controller to the outside world. Ever since then, I’ve wanted to build some sort of embedded project of my own. I finally motivated myself to build something I’ve always wanted–an alarm clock that works the way I want it to.
Here are the features of my ideal alarm clock:
Accurate to within a minute per month. Even better would be to synchronize to some time source.
Shows date, time and day of the week (so after a rough night, I know for sure if it’s a workday or not =D )
Easily visible during the day and at night.
Time adjustment allows adding or subtracting hours and minutes. I hate missing the correct minute on my current alarm clock and having to hit the set button 59 more times.
Alarm can be enabled/disabled according to the day of the week. Do I need an alarm on weekends? No. Am I so lazy that I don’t want to turn the alarm on and off every weekend? Yes.
Here are the items needed for breadboarding. This will be slightly different than the final bill of materials for the finished clock due to the breadboard power supply.
Note on LCD display: I purchased my display off of Ebay for $5 and it works great. If you decide to use SparkFun’s display, keep in mind that it requires a resistor in series when you supply power to the backlight. The resistor is not included in my schematic because my display has the resistor built in.
The notes on the image should give you an idea of what the components look like and what they are for. You will need to study the schematic to hook everything up correctly. If you are feeling lost at this point, read through the first two SparkFun tutorials then stop back. They will walk you through setting up the breadboard’s power supply and loading code onto an ATmega168.
If you’ve gotten this far, you’re probably interested in the code behind the alarm clock. It is available here. Keep in mind this is not a finished product yet so there are still some features missing. The RTC (real time clock) code is fairly solid though.
I already have a PCB layout ready in Eagle which I’m going to send out to get printed. I’m really looking forward to migrating from the breadboard to the finished product. I’ll make sure to post the result!
I finally got around to recycling some of the old electronics sitting in my closet by bringing them to the Hennepin County recycling center. I thought I was going to cry when they threw (literally, I’ve never seen a desktop computer fly so far) my old computer to the back of the huge container of TVs, stereos, and monitors. It was utterly worthless but I had a lot of memories attached to that aluminum box–namely LAN parties and college dorm life.
It gave me a lot of grief with 3 blown mobos and 1 dead powersupply over its lifespan. It was built during the height of the “modding” craze if you remember that. I made sure my box was rocking with a side window complete with a custom fan grill and blue cathode lights. No one could top my built-in car cigarette lighter, proudly installed in the spare 5.5″ bay. This is the one piece I kept. Maybe someday it will see new life in a desktop of mine.
Goodbye computer. If I had space in my closet Tutuapp APK, you wouldn’t be shredded and melted for scrap metal.
On Thursday night Tally and I dropped Natalie off at a friend’s and headed over to the Taste of Minnesota. As far as I can remember, it’s my first time there. I always imagined there were fun and interesting foods to try there. I was a little disappointed to find, after finding parking, a long walk, waiting in line for food tickets and a wristband, and waiting in line for food that all they had to offer was Grainbelt Premium, corndogs, and other fried fare. I don’t think any of it except for the giant freezies cost less than $5.
The music almost made up for this all–I enjoyed Chevelle back in college and Tally was also excited about Staind. I got there as the band had already started but was in time to hear “The Red” so I was happy.
We woke up early to drive out to Annandale for my family reunion which is held over 4th of July weekend. As always, it was a good to see the extended family. Someone had the idea to have a canoe war this year. I’m proud to say my cousin Erik and my canoe was one of the few to still be afloat after everything was said and done. Some at the reunion were meeting Natalie for the first time and everyone loved holding her. Perry and a few others witnessed her crawl for the first time down a small hill by the lake. She has been Tutuapp APK scooting along for a week but this was the first time she did it on hand and knees.
