When I hit the play/pause button the keyboard, a completely different song starts playing while the one I wanted to stop pauses. I kept hitting the button and listening to them alternate back and forth. Very odd behavior until I figured it out.
Apparently both my normal MP3 player software and Amazon Cloud Player (ACP) are aware of the play/pause button on my keyboard which I use to start or stop the music. Probably I was playing my normal MP3 player and hit pause, which paused it and started ACP.
Amazon had a $5 album sale, so I bought a few. They push their Cloud Player software as the method to download the MP3 files to my computer. I’ve given up trying to fight it.
But maybe that was mistake.
Amazon really wants me to use their software for my player. But I really do not want to use it. I only ever have it running when it launches to download songs. I usually immediately close it after that.
Maybe this is why I do not work in sales. Maybe this is why I should never go into management.
Bragging about a potential customer selecting my product or service over another seems like a really stupid thing to do. The potential customer announcing the selection of something over another is okay to me. The provider smacks of arrogance. You were the least worst option. The fewest number of people hated your software. That is not something to brag about to everyone. It sounds bad to open say the product was the least worst and plenty of users hate it, so it gets couched in terms that make it sound like the customer will work with the providers to improve it. Everyone should understand nothing is going to really improve. This is just empty platitudes so screwed people feel not so bad about it.
Maybe I need to stop following some corporate lackeys on social media so this kind of thing stops annoying me. Oh, wait, we do it too.
This Linux tool is my new best friend. We get thousands of XML files from our clients for loading user, class, and enrollment information. Some of these clients customize our software or write their own software for generating the XML.
This means we frequently get oddities in the files which cause problems. Thankfully I am not the person who has to verify these files are good. I just get to answer the questions that person has about why a particular file failed to load.
The CE/Vista import process will stop if its validator finds invalid XML. Unfortunately, the error “An exception occurred while obtaining error messages. See webct.log” doesn’t sound like invalid XML.
Usage is pretty simple:
xmllint –valid /path/to/file.xml | head
If the file is valid, then the whole file is in the output.
If there are warnings, then they precede the whole file.
If there are errors, then only the errors are displayed.
I use head here because our files can be up to 15MB, so this prevents the whole file from going on the screen for the first two situations.
I discovered this in researching how to handle the first situation below. It came up again today. So this has been useful to catch errors in the client supplied files where the file failed to load.
1: parser error : XML declaration allowed only at the start of the document ï»¿ <?xml version=”1.0″ encoding=”UTF-8″?>
That may be because he is using them wrong. I liked photography as a kid, but I didn’t know any photographers. Flickr happened to come into my life just after I bought my first digital camera. My participation in photography exploded. Not because I had a way to post my photos but because I had a way to find other local photographers for mutual encouragement. Even better was forming local groups to encourage people to meet. The value of Flickr is developing the community.
Similarly, I got into Twitter because my community, peers at other universities running the same software as myself, were seeking help there. Any place with answers to the problems we face, which is where people with the answers are watching, is where we go. Twitter was the place to get the attention of the right people not a forum like phpBB. (There are already lots of email lists.) My other community, people using the software I run are also on Twitter. I’ve resolved issues for many clients by finding their public complaints and offering solutions. When my focus changed away from using Twitter for the community is when I stopped liking Twitter.
Personally, I have yet to find much sense of community in the phpBB, Google Wave, and Ning. So I find it strange these are the exemplars of community applications. They seem fractured so one finds dozens of groups to covering the same interest. Sometimes this is because some moderator upset a portion of the community with draconian behavior causing people to form an alternative community. Bad blood exists for a while. Other times people set up a new community unaware others exist.
An effective way to explain something is to use a metaphor. This can be especially effective by picking an metaphorical object or behavior with which the audience is already familiar.
The one I see most often is comparing computers to a car. This morning I saw this on an email list describing a person’s experience migrating to Vista 8 from Vista 3.
It is like I have traded in a familiar (though frustrating) car for one that has the lights, wipers, and radio in new locations.
Also this morning, Vista 8 was compared to a malfunctioning pen forced on faculty who would rather use a better pen. Nevermind all pens are not used exactly the same. (Fountain vs rollerball) Some require more maintenance and care than others.
A coworker always says Free Open Source Software like Sakai or Moodle are free as in free puppies not free beer. Nevermind proprietary bought systems like Blackboard are bought as in bought puppies.
I noticed one the nodes in a development cluster was down. So I started it again. The second start failed, so I ended up looking at logs to figure out why. The error in the WebCTServer.000000000.log said:
weblogic.diagnostics.lifecycle.DiagnosticComponentLifecycleException: weblogic.store.PersistentStoreException: java.io.IOException: [Store:280036]Missing the file store file “WLS_DIAGNOSTICS000001.DAT” in the directory “$VISTAHOME/./servers/$NODENAME/data/store/diagnostics”
So I looked to see if the file was there. It wasn’t.
I tried touching a file at the right location and starting it. Another failed start with a new error:
There was an error while reading from the log file.
So I tried copying to WLS_DIAGNOSTICS000002.DAT to WLS_DIAGNOSTICS000001.DAT and starting again. This got me a successful startup. Examination of the WLS files revealed the the 0 and 1 files have updated time stamps while the 2 file hasn’t changed since the first occurance of the error.
That suggests to me Weblogic is unaware of the 2 file and only aware of the 0 and 1 files. Weird.
At least I tricked the software into running again.
Some interesting discussion about these files.
Apparently I could have just renamed the files. CONFIRMED
The files capture JDBC diagnostic data. Maybe I need to look at the JDBC pool settings. DONE (See comment below)
Apparently these files grow and add a new file when it reaches 2GB. Sounds to me like we should purge these files like we do logs. CONFIRMED
There was a bug in a similar version causing these to be on by default.
Back around 2001, the CIO received complaints about performance for the web server. So, I went log trolling to see what the web server was doing. A single IP dominated the HTTP requests. This one IP passed various last names into the email directory. Some quick research revealed Apache could block requests from that IP. That calmed things down enough for me to identify the owner of the IP. The CIO then bullied the ISP to provide contact information for the company involved.
Previous little adventures like this landed me a permanent job, so I jumped at similar challenges.
Well, a few years later, it happened again. This time my boss had made me develop a script for the dissemination of the anti-virus software package to home users. Basically, it used email authentication for verification if someone could get the download link. So, I applied the same technique to the email directory. Well, this upset some people who legitimately needed email addresses. So the human workers would provide email addresses to people with a legitimate need.
I’m glad since I’ve left, VSU no longer looks up email addresses for people. (I thought some of the requests questionable.) Also, my little email authentication script was before LDAP was available to the university. I think the new solution much better.
One the more vocal complainers about my having stopped non-VSU access to the email directory was my current employer. We apparently list email addresses for employees freely. Which makes me wonder how much spam we get is due to the brothers described at the beginning of this story? Or other email harvesters? Just hitting the send button potentially exposes the email address.
From 2001 to 2006, Microsoft Outlook was the email client I used for work (and on my home computer to access work stuff). Back then, Exchange was not available, so a number of the features were more hacks than reality. However, it worked pretty well.
When I changed jobs, Netscape and Thunderbird were the pre-installed clients. I opted for Thunderbird. It worked pretty well for me. Calendaring was in MeetingMaker. Everything worked pretty well.
Recently work shifted to Exchange, so going back to Outlook made sense. Maybe because I have so much experience, the transition was not as bad as it might have been. Still… These are gotchas which have annoyed me lately:
Editable subject usability: The emails from our client issue tracking system put the description where its hidden. I was really pissed that I could not edit the subject until I figured out unlike most software which changes the shading to show it is now editable, Outlook just lets me edit at any time. Also, editing the subject after it is used by something else like a task results in the change in the email but not the task. (The main reason I want to change them is so it appears correctly in the task list. ) Copying to a second email results in the same problem. Apparently I have to either create a new task and copy-n-paste the subject I want or forward the email to myself.
Spacebar moves to next message instead of next new message: I really like the Thunderbird method of skipping to the next unread message when I hit the spacebar at the end of the current message. It even will find the next unread message in another folder. Outlook just advances to the next message.
Boolean is more than OR: I had this fantastic Thunderbird filter which looked for user@ AND domain.tld. Outlook only honors OR. We have 15 admin nodes and databases which send up reports. Alerts and tickets come from a different source and unaffected by this.
Search ignores special characters: I thought in the past I had sent email to firstname.lastname@example.org. However, the message bounced, so I searched my email for part of the address “abc-defghi” as its not in the address book. I got results which match “abc” not “abc-defghi”. So it ignored the hyphen and everything after. FAIL!
Send email as plain text or paste a plain text: Yes, I know lots of people have HTML capable clients. I hate Outlook puts my replies in a sickly blue font. When I copy and paste from the elsewhere in the message, it changes the font. So then I have to go and do formatting to have a presentable email. I just want to type and send. I don’t care about fonts, colors, etc. If I did, then I would create a web page. … (Added 2009-JUN-03)
