The Curious Case of Sharepoint and file uploading

Its been a frazzling sort of morning… We’ve been trying to migrate some of the Schools finance information from a shared folder space tied down with access rights… As its become more complicated to sort out who has access to what, the user rights list has gotten mixed up over time… So I had the bright idea to move it to a Sharepoint area… Me and my big ideas.

We’ve been playing with the Webdav connection and thought that it was going to be a simple process of file copying from one area to another… One of those two minute jobs that took much much longer to resolve than you thought… You know the ones.

The problems began when we compared the files in the original folder to those that were in the new folder… It was out by over 90 files but there had been no error reported back. Tried copying the files and folders again using a sync tool with a report and got a number of “Access Denied” or “<file> to large to copy” messages. It was only when we tried uploading the file manually to Sharepoint that the penny finally dropped

The file name is invalid or the file is empty. A file name cannot contain any of the following characters: \ / : * ? ” < > | # { } % ~ &

OK, so now we have the root cause of the problem, invalid characters in filenames and folders…. But how many of them do we have… Thats when we found that Windows Search is a pain in the arse… trying various incarnations of “&” or “*&*” just yields a result of all files and it was only after finding a random entry in a forum post that we got the answer that must be preserved across time; To find any of the invalid characters listed above, put the following in the search bar:

file:”&”

and you will find all the file with & in the title… Found 11 of those. But when we looked up + we found 90+ items… Passed that one back to the office to fix.

Misadventures in Computing – Outputting a Mic on a PC directly to some speakers

This is a repost of an article I posted on the School of Computing Science and Digital Media.

Over the summer, we went through an upgrade of one of the IT labs… The carpet was looking a bit shabby after some rain last year and we were going to have more students that we could hold in our foundation year lab. The lab was fitted with connectivity through from the big lab so sound and vision could be played throughout.

We have already had problems with the connectivity; the new projectors and connections were fitted first so they could make as much mess as they wanted during the install. Unfortunately when the carpet fitters came in they pulled down the shelves that held the amplifier and disconnected all the cabling. Since putting it all back together, it’s never been totally right.

So, here we are on day one of a New Semester and the lecturers running the First Year lab come through and tell us that there isn’t any sound from the Microphone going through to the second lab… A call to the company that installed the system gives us a date of Friday for the Engineer so we need a workaround NOW!

My suggestion is to hook up a USB condenser mic we have and play the sound through the PC. OF course, by default your going to need some sort of App to play the sound… But through the glories of the Internet one of the sys admin support team came across this nugget on superuser.com (specifically this post)

1) Right click on the speaker icon in your system tray (bottom right of your screen). Go to recording devices.

2) Locate your microphone in the list. I am assuming it is not disabled as you mentioned examples of it working previously. Right click, go to properties.

3) Switch to the “Listen” tab, check off “Listen to this device”. While Listen is checked, your microphone will be audible through your speakers.

Tested it and it works… now we have a workaround to get us through the rest of the week.While Listen is checked, your microphone will be audible through your speakers, and in a more advanced facet, through stereo mix. So if you wanted to record your Mic and Stereo Mix, this is how you would do it, but at the expense of being able to still hear your mic (it throws most people off, like myself).

Cooler Master Cosmos II Unboxing – Extreme PC Building

Take a read about Daniels review of his new Cooler Master Cosmos II case.

What he hasn’t mentioned us how he came about getting this case; He won it in a competition that was run by Cooler Master themselves… But I already get ahead of myself. First we need to rewind about a month….

Daniel is our local expert on video production in the School of Computing at RGU and we were having a discussion about some new HP workstations we were speccing up for Video editing. I casually asked Daniel what he had at home and was a little shocked (and deeply disappointed) to find that all he had stay home was an ageing laptop.

He was shamed by my disappointment I think because the next I hear is that he is speccing his own new über-workstation. As part of this he entered a competition for the case for his world dominating machine… And he won, with this text.

And the winner of the Cosmos 2 is: Daniel Doolan!

As reason why Daniel deserves to win a Cooler Master Cosmos 2 he gave:

“I am looking to build my first PC from scratch and am looking for a case that will allow for future expansion.
I lecture in Computer Science at University and our Computer Systems Manager was horrified to hear that I had been running a laptop at home for the past few years.

He was expecting that I would have been running a really over the top extremely overclocked machine.
So this is a chance to build a machine for myself that will hopefully live up to the expectations of what our Computer System Manager would expect from me (he always comes to me when we go shopping for new equipment for the School from renderfarms and 3d motion tracking systems to high-end video cameras).

I lecture quite a bit in the area of Multimedia, and really do need to put together a beefy machine to handle audio/video/ 3d rendering allowing me to work easier from home.

Another thing I do quite a number of times each year is to go around to schools and give workshops on topics such as computer networking, games programming and building a PC.
At present the lecture slides I have for this are fairly old, and deal with just a very bog standard system.

By building my own high end machine I can use some photographs / videos in my presentation to illustrate just what can be created.

From reading the specifications I believe this case is one of the best available and provides more than enough room for future expansion.”

Glad to have been of help Daniel

Dr. Daniel C. Doolan News & Photos

Cooler Master Cosmos II Ultra Tower Case Unboxing. If you are building an extreme gaming case then this is certainly one to consider, providing you with 13 HD bays, support for more or less every type of motherboard, graphics cards up to 15.5 inches in length. It also allows for the installation of a 360mm rad on top and a 240mm rad at the bottom (with the removal of 6 hard disk bays) to create a nice watercooling loop to cater for all your CPU & GPU needs.

The big question is what components would you put into a case like this, in particular what type of system would you install for cooling – would you go Air or Water? If you go for water cooling would you go for an integrated system like the Corsair H100 or go with a set of rads something like those from hwlabs (you…

Stanford and Berkley free online courses running for another session.

Back in Autumn 2011, Stanford university announced that it was going to provide some of its course material online for free (Read my original post here). Evidently this was successful because they are doing it again in January/February 2012.

Relevant Computer Science and Entrepreneurship courses running are:

Lean LaunchpadTechnology Entrepreneurship

CS 101Machine LearningSoftware as a Service

Human-Computer InteractionNatural Language Processing

Game Theory, Probabilistic Graphical ModelsCryptography

Design and Analysis of Algorithms IComputer Security

As previously, the courses are going to be primarily video based. There is no direct access to the tutor but there is a Q&A forum in which students rank questions and answers with the top ranked of those followed up with during a lecture. All student work is assessed using an online evaluation tool that will evaluate the progress of the student during the students time on the module. Quizzes and exams will also be administered electronically.

Stanford University modules to run for free this Autumn 2011

— Update —

This must have been a successful experiment because Standford and Berkley are at it again in 2012… Read about it here

–End —

This Autumn, and running through from October to December, Stanford University is running a distributed learning experiment and allowing worldwide, online participation of three of it’s modules and it is totally free. Of course, you are not a Stanford student and you won’t get a certificate for your endeavours. However You will receive a statement of accomplishment from the instructors which will include information on how well you did and how your performance compared to other online students.

The course is going to be primarily video based and work is ongoing currently to provide text transcripts to make them more accessible. You will not have direct access to the tutor on this course; questions can be submitted but only the top ranked of those will be followed up during a lecture. Instead, students will be using an online evaluation tool that will evaluate the progress of the student during the students time on the module. Quizzes and exams will also be administered electronically.

The three courses available are:

An introduction to aaArtificial Intelligence
Introduction to Databases
Introduction to Machine Learning

You can register your interest to apply by email currently with further details being released later in the summer.

Highlights from SXSW 2011

Earlier this year in March SXSW took place. For those not in the know SXSW stands for South by South West and is a set of three festivals that takes place in Austin, Texas in the US. The three conferences concentrate on Music, Film and Interactive. In the interactive portion many web startups and technical experts come together in a very creative environment. Last year the one big big thing that came from South By South West Interactive was checkin services like Gowalla and Foursquare which have gone on to be massively popular in social networking terms…

This year, from what I read and listened about, these are the things that were hot and may be ideas for student projects or social networking tools for learning:

Game overlays on Real Life…. “Gmaification” as it has been termed. The biggest company at the forefront of this is SCVNGR (scvngr.com). SCVNGR (taking the current trend of dropping vowels in words) adds hotspots and clues on maps to create virtual scavenger hunts which lead to badges (virtual) or perhaps prizes (free burger for getting to the end etc etc). Playing SCVNGR is free but it costs to set up.

Group Messaging…. This has been a bubbling topic anyway but SXSW seems to have kicked it off big time… Group messaging apps such a beluga or Group messenger bring groups together across multiple platforms and different messaging styles. Both the apps I mentioned have web front ends, desktop apps, iPhone and android apps and also allow text messaging input as well. Group owners (or pod owners in Belugas case) set the membership and conversations are read and replied to within that specific group… As flexible as twitter but you are not broadcasting to the entire world.

The topic of Web 3.0 is starting to rear it’s head… Coined again by Good ole Tim Berners Lee. The last time I saw him at TED he was angling towards a data driven web and it looks that this has further refined itself to what he called ‘sensor-driving collective intelligence’ where things like phones and cameras and other data gathering devices will become even more the conduit to the information we absorb from the Internet. I guess this is kind of live in a small way from the Japan Tsunami and nuclear plant disaster where radiation counters have been set up with their output going on to the web so people can view radiation levels in particular areas.
