An interesting opinion post in the NY Times describes the research on early education and how it can affect IQ [1]. Among other things children from poor families who are adopted into upper middle-class families tend to end up with higher IQ scores. The article notes that half the population in 1917 would be regarded […]

Appropriate Talks about Porn

There is currently some discussion about a talk which used pornographic imagery and jokes to illustrate points about Ruby programming [1]. A similar event happened in 2006 here is the description of the event from the author – which includes an unreserved apology [2].

It seems to me that the current discussion focusing on what […]

The Main Security Problem

All security problems are to some degree people problems. Code may be buggy, but it was written by people who could have been better trained, had more time to spend on code review, etc. When there are multiple programs, OSs, libraries, etc to choose from then choosing a suitable combination of software is a matter […]

Dom0 Memory Allocation and X

I’ve previously written about memory squeeze problems in a Xen Dom0 when large amounts of memory were assigned to DomUs [1]. In summary the Dom0 would have problems if started with default options and the majority of the RAM was later assigned to DomUs, but if the memory of the Dom0 was limited by the […]

CPL

I’ve just bught an NVidia video card from Computers and Parts Land (CPL) [1].

I asked for a PCIe*8 card but was assured that a PCIe*16 card would work. However when I got it home I discovered that it would not fit, the size difference was obvious enough that I didn’t even need to unwrap […]

Too Stupid to be a Judge

Bruce Schneier has written about the foolish actions of Justice Antonin Scalia [1]. Antonin made some comments opposing the need for greater privacy protection, most people could get away with doing that, but when a Supreme Court Justice does so it gets some attention. In response to this Fordham University law professor Joel Reidenberg assigned […]

Redundancy in Network Infrastructure

It’s generally accepted that certain things need redundancy. RAID is generally regarded as essential for every server except for the corner case of compute clusters where a few nodes can go offline without affecting the results (EG the Google servers). Having redundant network cables with some sort of failover system between big switches is regarded […]

Email Passwords

I was doing some routine sysadmin work for a client when I had to read mail in the system administration mailbox. This mailbox is used for cron job email, communication with ISPs that run servers for the company, and other important things. I noticed that the account was subscribed to some mailing lists related to […]

Creating a Double-Ended Bun

The people who made the above magazine advert gave it two top-halves to the burger bun. But I think that there is actually a demand for such buns, and that it is possible to make them!

Traditional buns have a flat bottom where they rest on a baking tray. One solution to this problem […]

Links April 2009

P. W. Singer gave an interesting TED talk about the use of robots in war [1]. He briefly covered some of the ethical and social issues related to robot soldiers as well as showing many pictures of existing robots.

Since November 2007 there has been a request for Google Gears to support “Iceweasel” (the Debian […]
