This screenshot is of our database app that has consumed, devoured and assimilated the past six months of our time at SATV. By the middle of January we will throw out our three-ring binder with printed calendar pages and it will all go on a workstation (backed up regularly, mind).
There’s just one thing: It’s too small! Our workstations are all Dell Optiplex 960’s with the 19” integrated LCD option; they look great and are otherwise very readable.
But why is the default font Segoe UI at 8 points?! There are multitudes of form boxes on computers around the world doing what this machine is doing, across all industries and verticals.
All of them use Segoe UI. 8 points.
All of them.
This particular app, which I’ve redacted to save the embarrassment, has many of these form entries. They all use at most a third of the available screen space. (Note the tiny record paging control at the bottom. That is 6 pt if anything.)
This app, like many others, is built on Access 2003. I spent a lot of time on Access 2007 writing SQL queries to import our old equipment Excel spreadsheet into this app. At least that UI let me up the font size in Design View so I wouldn’t have to look at tiny SQL statements.
In this runtime, albeit an Access 2003 runtime, there’s no obvious provision. The only potential solution will come when that workstation and all of our Vista machines, will be upgraded to Seven in a few months; Windows 7 has a screen magnifier, much nicer than previous versions and more like the excellent magnifier in Mac OS X. That’s what I’ll have to use when I’m on that app.
Raymond Chen happened to mention accessibility in one of his recent posts, where a commenter suggested that accessibility was an altruistic endeavor and could be outsourced. Raymond says:
Sure, why not. Just like in real life, you can hire someone to do your programming taxes for you. If you would rather hire another company to come in and add accessibility support to your application, then more power to you.
Yes, accessibility is one of those altruistic things, but so too is not consuming 100% of the CPU all the time, or being usable at high DPI or color schemes different from the Windows default. Sure, you can write your program so it doesn’t work at high DPI, and requires the user to use the Windows default color scheme, and consumes 100% of the CPU all the time, but each time you do this, you alienate another percentage of your audience. (Not supporting accessibility will cost you a pretty large audience, because governmental agencies usually have accessibility as one of their requirements.)
The comment thread is worth reading; commenters touch on all the points I’ve made before, including broken high DPI in Windows 7 and the amazing insensitivity of the Linux community towards its disabled users.
SATV recently got a device that will make our network a bit more reliable. Over the past several years, we’ve seen hardware monitors (like the environmental monitors made by IT Watchdogs that I wrote about before) and remote reboot/remote power devices drop dramatically in price. Devices that were once only in high-end data centers are now available to small shops and small budgets.
This is a Server Technologies CW-8H. It’s around $350. It has 8 outlets, a digital ammeter, and the most important part: An Ethernet connection.
Each of the 8 outlets can be individually controlled from a web interface, Telnet, SSH or SNMP agent. The photo doesn’t show this very well, but each outlet has an LED to indicate power status.
I asked for this device to solve a problem: As more and more Ethernet-connected devices come out, a number of them have taken shortcuts in their management interfaces. Some devices—hello, SMC 8014 cable modem!—are known to get flaky while in use.
Unfortunately, some of these same devices—hello, SMC 8014, again!—either don’t have a reboot button on their Web interface, or else the same bugs that affect their operation keep them from being accessed remotely at all.
I and SATV still have painful memories of the time during a blizzard when our main network switch (an SMC model we’ll never use again) had a power failure, as did the rest of the building. When power came back up, the switch kind of came back.
It put us off the air.
I came in a day later, after the storm had passed, thinking the worst (power surge killing every NIC in the building…)
I power cycled the SMC switch. It came back up completely.
I was livid!
Fast forward a few years later to this fall. It’s Halloween season and we have a very popular parade that kicks off the season and is streamed online for the many Salem expatriates and Halloween celebrants.
During setup, I tested the video stream from one of our Macs to Ustream.tv. It worked all morning.
At a critical time in early afternoon, when my producer is trying to nail down our timeline, the stream stops working. Panic.
I’m thinking Comcast blocked the port, as the problem was presenting itself.
Log into the modem. Do tests. Find everything’s OK past the cable modem.
But remember I said there was no reboot button? I power-cycled the modem; with the ac adapter/brick in this and most devices it is a pain.
Tested the stream. It worked.
That poor cable modem is handling all of our NAT until I find a “real” firewall. At some point it must have decided to screw up its NAT table.
That’s why we have this $350 power strip, in case our board of directors is reading this.
It works, as you can see in these photos with my work light, a 46W fluorescent from Home Depot.
The PDU monitors its power usage.
This won’t solve all our problems; I could still have to come in if the cable modem locks up. But it will be useful for this, and the other devices that need power-cycling, such as our PBX and our fax modem.
My only complaint so far is that, like too many management devices that use email, there is no test available on the management web page to configure email. I’m pretty sure that although I configured email on the device, it is not getting to Exchange. That’s a common problem with SBS 2008 and needs a custom SMTP connector to fix, which I will remember to get to before I put the PDU in service.
If you’re a small shop, look into Server Technology. They have devices as small as 2 outlets with the same functionality for about $220.
