Local Uncertainty Maximum

Posted By Tim Bray

Welcome to the end of the year. As I look forward into 2012, I foresee, uh... almost nothing. In fact I cant recall a time when the uncertainty was so pervasive. Here is a small compendium of prognosticational impotence. Asia Every year that China goes on just going on astounds me. Even if everything went just right, the law of big numbers is making it harder to sustain 10% annual economic growth; and the political bargain in recent years has been that the middle class should shut up in the face of brutal oppression and pervasive corruption, in exchange for the growth-driven flow of prosperity.

Tying Up Phone Lines as a Cyberattack Tactic

There's a service that can be hired to tie up target phone lines indefinitely.

Hacking Marconi's Wireless in 1903

Posted By Bruce Schneier

A great story: Yet before the demonstration could begin, the apparatus in the lecture theatre began to tap out a message. At first, it spelled out just one word repeated over and over. Then it changed into a facetious poem accusing Marconi of "diddling the public". Their demonstration had been hacked -- and this was more than 100 years before...

The Dumbest Idea In The World: Maximizing Shareholder Value

Posted By Tom Limoncelli

For a long time I've had some serious issues with CEOs putting such a focus on the stock price instead of customer satisfaction. I've usually figured that I was an outsider, too ignorant of how economics or how business works to know any better. In fact, there was a time (about 5 years ago) that I was seriously considering going for an MBA so I could understand this all better. However I realized that what I really wanted to do was wait for various principles to be explained (like, "focus on shareholder value") and bring up my all my counter-examples. That's not a good reason to get an MBA.

Parsley and the dead VoIP ATA

Posted By Greg Lehey

Things always fail at the most inappropriate time. Round midday I started work on the turkey stuffing, and couldn't find the parsley. Tried to call Yvonne, who was at the Yeardley's, and the phone started ringing immediately. Normally there's a one or two second delay while the VoIP network does its thing. Despite other failings, Telstra provides an apparently immediate connection. So clearly I was being connected via Telstra. Why? Closer investigation showed a very hot, non-responsive ATA. Power cycling didn't help: it was dead. Not the end of the world: I have two of them from the days when I worked (homephone.lemis.com and officephoqne.lemis.com).

Type-System Criteria

Posted By Tim Bray

Starting some time around 2005, under the influence of Perl, Python, Erlang, and Ruby, I became convinced that application programs should be written in dynamically-typed languages. You get it built faster, theres less code to maintain, and the bugs are no worse. Ive felt negative not just about statically-typed tools in general, but about the Java programming language in particular. Living in the Android world has forced me to think about this more. The Old Argument Its remarkable that, fifty or so years after Software Engineering joined the mainstream, we have so little consensus on these issues. There are many people, including some here at Google, who think that doing large-scale software engineering without recourse to static typing is unprofessional, verging on malpractice.

Super Wi-Fi is better than just "super"

Posted By Tom Limoncelli

[This is still at 'first draft' quality, but I thought I'd post it sooner rather than later. Please ignore the typos for now.] I recently twittered my delight that the FCC approval of "super Wi-Fi" is going to be regarded as a historic moment five years from now. I mean it. Here's why: In geek terms: This gives permission to treat the airwaves like Ethernet networking, not like Teleco networking. More modern and more flexible. In non-geek terms, this decision by the FCC makes it easier to innovate. It makes it safe and easy to try new things With the possibility of experimentation comes new applications and ideas.

DxO conversions: preliminary verdict

Posted By Greg Lehey

I processed all the photos above with DxO Optics "Pro" and the realistic profile for the Single-shot HDR. It's a good compromise. In some cases, I think it would have been better without, but it reminds me of the first film I took in an Asahi Pentax “Spotmatic”, over 45 years ago. I didn't even need to print the negatives; compared to the results I got with my SV (despite exposure meter), everything just looked so evenly exposed that I was convinced. These results were similar. Went to some lengths to compare them in more detail, including writing another script to generate web pages, but it's clear that I need to do more than that.

Coming to terms with DxO

I returned Chris Yeardley's laptop to her yesterday, as promised. But that wasn't the best of ideas: now I have purchased DxO Optics "Pro" and don't have any machine to run it on, and that on the day of the month where I have the most photos to process. Over to Chris' place to borrow another machine, this one running Microsoft Windows XP. Setting up was amazingly easy compared to Windows 7, and I was going to praise it for ease of use until I discovered that this was a machine I had already borrowed and configured 8 months ago and been through similar pain then.

Stopping SOPA

Posted By Tom Limoncelli

The problem with companies that used to support SOPA but have turned around, is that they supported it in the first place. The problem with stopping SOPA is that the people behind it are committed to bringing it back in another form, some day, some how. The problem with SOPA is that many of the bad things in SOPA are things that the U.S. government has been doing lately either unofficially or through "cooperation" with companies. The defeat of SOPA will not be the end of the general problem.

Hard disk docking station

Posted By Greg Lehey

Notification slip in the letter box today: a package had arrived for me. I've been waiting for a rotator for my camera, so went in to the post office to pick it up. And of course it was the other package, the eSATA docking station that I ordered at the same time. Sure, I want that too, but it wasn't nearly as important. Unpacked the device and discovered it wasn't exactly what was advertised. Yes, it has two disk slots, but one's for PATA and the other's for eSATA: The instruction booklet proved to be only to describe how to use the supplied software (for Microsoft only, of course) and the on-device firmware for hardware cloning, copying a disk in an unspecified direction.

Electric collars: useless

Posted By Greg Lehey

Nemo's electric collar was dried out today, and it works again. Went out for a walk to try it out. Not a revelation. The range seems to be about 10 metres when you're lucky, and you can't rely on it to work further away than 3 metresless than the length of the leash. Nemo noticed the vibrator when it was set higher than about 30%, and looked at us with interest. Certainly nothing to stop him in his tracks. If the shock works at all, he did a good job of ignoring it. There are two issues here, of course: is this particular device a good example of its kind, and does an electric collar make any sense for dog training?

Fixing RSS markup

Posted By Greg Lehey

Callum Gibson still wasn't happy with my copout in serving the RSS of my diary. It seems that there were two issues: relative URLs (a problem I've had to deal with again and again) and the onmouseover functionality. If I solved the first issue, I could at least display the before image, though experiments showed that onmouseover still broke the rendition in newsfox. Ended up writing a function to do the switch in HTML and just show the former image in RSS. I suppose Callum's happy now.

More photo comparisons

Posted By Greg Lehey

Spent much of the day playing around with methods to compare software, and finally came up with a set of pages showing comparisons between the four corners and the centres of photos processed in two different ways. It was a lot of work, and it's not perfect, but it shows a surprising number of things. Firstly, the DxO HDR function makes so little difference that it's barely recognizable. I spent about 10 minutes trying to work out why my mouseover function no longer worked, until I realized that the images were effectively identical (though with careful examination minor differences were apparent). The following discussion uses features that are not available in RSS.

Nemo does another runner

Yvonne returned from the morning walk this morning without Nemo: he had done another runner into the lagoon, and returned later with proof that there's still water in the lagoon. Clearly he hasn't learnt from his experience in the Wimmera last month. Time to put the electric collar into actionif he will pay attention to it. Tried it out, and it wouldn't register with the remote control: it was full of water. That's a clever construction. Took the collar apart to dry it out; hopefully it will still work when it's dry again.

New Years Resolutions and Time Management

Posted By Tom Limoncelli

One part of "The Cycle" is that you should keep a list of long-term projects and review it every few months. There are two specific times you should always review it: around budget time (this is where you record those great projects that are so big they'll require funding), and around New Years (the list usually inspires good New Years Resolutions). The list has a couple "secret" functions. First, when your main todo list is growing out of control, it can be very useful to move some of the more audacious goals onto this list. Secondly, sometimes an idea is taking up brain-space and you just need to write it somewhere.

Playing with DxO Optics "Pro"

Posted By Greg Lehey

Spent some time this morning considering how to compare the results of DxO Optics "Pro" with other image processing methods. Came up with a relatively mechanical system where I take two trees with files with the same name and generate 5 crops from each: top left, top right, centre, bottom left and bottom right. Then I created a web page with each image, using the established technique of mouseover image switch to show a direct comparison of each image. The first attempt was simply a single line per image (old and new), so it's not immediately clear what part of the original image it represents.

DxO Optics "Pro" 7: first impression

Posted By Greg Lehey

So finally I got Microsoft to the point where I could install DxO Optics Pro, another 200 MB of package. It downloaded relatively quickly, and once again I was left scratching my head as to how to use it. But it's user friendlier now: it now allows you to select files instead of projects, like all other programs in the Microsoft space by clicking on silly icons. For the test I had chosen the photos I had taken on 10 December 2011, all 371 of them. And of course it had to display icons for all of them, which took about 5 minutes.

DxO Labs have come out with a new version of their DxO Optics Pro package, which I tried some months ago, and which I had ultimately found too slow for serious use. The new version, they claim, is up to four times faster (a remarkable speed). But, again, it only runs on Microsoft and Apple, and the Apple version always lags the Microsoft version. So tried once again to borrow the computer that Chris Yeardley lent me last time. Surprise: I already have it, and I'm running my Internet gateway on it. But this is just for a testI must really get the 64 bit version of FreeBSD running on dereel so that I can run Microsoft in a VirtualBox with sufficient memoryso she offered to lend me her main laptop, with 4 GB memory, until the end of the week.

The Influence of the Ecstasy of Influence

Posted By Benjamin Mako Hill

Back in 2007, Harpers Magazine published The Ecstasy of Influence: a beautiful article by Jonathan Lethem on reuse in art and literature. Like Lewis Hyde in The Gift (quite like Hyde, as readers discover) Lethem blurs the line between plagiarism, remix, and influence and points to his subject at the center of artistic production. Lethem's gimmick, which most readers only discover at the end, is that the article is constructed entirely out of "reused" (i.e., plagiarized) quotations and paraphrases. A couple months ago, I suggested to my friend Andrés Monroy-Hernández a very similar project: a literature review on academic work on remixing and remixing communities constructed entirely of text lifted from existing research.

Computers or technology?

Posted By Greg Lehey

I have divided my diary entries into 10 different categories, regarding various things I do. Many blog systems have an order of magnitude more, but I think 10 are enough; in general it makes more sense for people to display all and skip stuff that doesn't interest them. But the titles of these categories awake certain expectations: the term computer increasingly leaves out large areas of digital technology. I also have photography and multimedia, and frequently the topics overlap. That's OK, since I can choose as many topics as I like, but maybe the tag computer is misleading for many topics.

We've been considering a remote controlled electric collar for Nemo for some time. The idea is to give the dog a mild electric shock if it is disobedient. Traditional dog trainers are, of course, horrified about the idea of giving the dog an electric shock, and it took us some time to accept the idea. From a purely training point of view, of course, most trainers accept that animals must be punished for disobedience, though rewards for good behaviour are much better. But in general punishment requires the proximity of the animal. Horse trainers can sing a song about that one.

Chasing the reception problems

Posted By Greg Lehey

Once again TV reception is terrible, at least on some channels. Over the months I've eliminated a number of causes, including poor cablesI thinkand cross-talk between the tuners. And more and more it seems to relate to specific channels and specific times of the day. But at the moment it seems to be happening all the time on some channels. At the very least, I need to find a way to monitor what's going on. One starting point is the program femon that I looked at a few months ago. It's like tzap, but it works when MythTV is running. The output is a little hard to interpret, but I can change thatif I could find the sources.

Expanding the Cloud  Introducing the AWS South America (Sao Paulo) Region

Posted By Werner Vogels

Today, Amazon Web Services is expanding its worldwide coverage with the launch of a new AWS Region in Sao Paulo, Brazil. This new Region has been highly requested by companies worldwide, and it provides low-latency access to AWS services for those who target customers in South America. South America is one of the fastest growing economic regions in the world. In particular, South American IT-oriented companies are seeing very rapid growth. Case in point: over the past 10 years IT has risen to become 7% of the GDP in Brazil. With the launch of the South America (Sao Paolo) Region, AWS now provides companies large and small with infrastructure that allows them to get to market faster while reducing their costs which enables them to focus on delivering value, instead of wasting time on non-differentiating tasks.

Hyder: Transactional Indexed Record Manager for Shared Flash Storage

Posted By James Hamilton

If you work in the database world, you already know Phil Bernstein. Hes the author of Principles of Transaction Processing and has a long track record as a successful and prolific database researcher.  Past readers of this blog may remember Phils guest blog posting on Google Megastore. Over the past few years, Phil has been working on an innovative NoSQL system based upon flash storage. I like the work because it pushes the limit of what can be done on a single server with transaction rates approaching 400,000, leverages the characteristics of flash storage in a thought provoking way, and employs interesting techniques such as log-only storage.

Apps are the New Users

Posted By Diomidis D. Spinellis

Some facilities provided by mature multi-user operating systems appear arcane today. Administrators of computers running Mac OS X or Linux can see users logged-in from remote terminals, they can specify limits on the disk space one can use, and they can run accounting statistics to see how much CPU time or disk I/O a user has consumed over a month. These operating systems also offer facilities to group users together, to specify various protection levels for each user's files, and to prescribe which commands a user can run.

Most of us have migrated our friends and loved ones to some Apple configuration or another; pain at both ends thus minimized. But times have changed.

Electromagnetic radiation causes cancer!

Posted By Greg Lehey

Probably the main objection that Wendy McClelland has to wireless communications is that they cause cancer. Nothing we can say can prove otherwise. One of the problems, of course, is that electromagnetic radiation, in sufficient dosage, really does cause cancer. How much? As I've noted previously, the presentation of the data doesn't make it easy to compare. I established that the maximum radiation from the NBN tower would be about 41 ¼W/m². But what's the level of solar radiation? Discovered a new word, Insolation, along with some typical values: about 1 kW/m² in bright sunshine. There are more specific pages at Aussie RV products, which shows an average of 5.1 kWh/m² per day in Melbourne, and the Bureau of Meteorology, which shows a map of Victoria showing a current insolation of about 33 MJ/m² per day.

Wide Scream

Posted By Benjamin Mako Hill

https://upload.wikimedia.org/wikipedia/commons/d/de/Aspect-ratio-4x3.svg https://upload.wikimedia.org/wikipedia/commons/f/f8/Aspect-ratio-16x9.svg It seems that nearly all computer monitors have now switched from a 4:3 aspect ratio popular several years ago to a "wide screen" 16:10 and now mostly to an even wider 16:9. But screen sizes are usually measured by their diagonal length and those sizes have not changed. For example, before I had my Thinkpad X201, I had a X60 and a X35. They are similar laptops in the same product line with 12.1" screens. But 12.1" describes the size along the diagonal and the aspect ratio switched from 4:3 to 16:10 between the X60 and the X201. As the screen stretched out but maintained the same diagonal length, the area shrunk: from 453 square centimeters to 425.

Make an assumption as to the average number of apps a new Android gets loaded up with, and multiply that by fifteen million to estimate how many of the billion downloads are to new devices.

Posted By Greg Lehey

More work on the middle of the eastern garden today. Planted a number of bulbs, I think Hippeastrum, in what was once bed number 2, and set to to remove the remaining strawberry plants, which proved to be carrying a significant number of worm-eaten fruit. I must have collected 50 plants of various sizes, and there are still a number to be done. Sent out a message on Freecycle, which their software showed (almost) correctly in the preview window and then wrapped unappetizingly in the final post.

Strange weather for summer

Posted By Greg Lehey

Since writing my weather station software, now a couple of years ago, I've been continually monitoring the results for errors. So this one caught my eye today: On checking, though, it's correct. The highest temperature of the last 5 days was 23.9°, at 0:53 on 30 November 2011. I'm continually amazed how variable the day's temperatures are.

Bits as a Service

Posted By Tim Bray

It is true, if inconvenient, that information wants to be free. Which fortunately doesnt mean were done with Art or Journalism or the other services embodied in bits. Stewart Brand He coined the phrase in 1984; the original is On the one hand information wants to be expensive, because it's so valuable. The right information in the right place just changes your life. On the other hand, information wants to be free, because the cost of getting it out is getting lower and lower all the time. I disagree with the first half: Information qua information, as in facts, wants to be free not expensive; things like the best route from here to the airport, the closing price of Google shares, and election results.

Supporting Software Inspections and Reviews

Posted By Robert V. Binder

In every software project where I’ve used some form of review process (formal inspections, walkthroughs, or reviews), the gain has always justified the pain.  Invariably, some developers really dislike this process, leading to tantrums reminiscent of Orange Country Choppers. But every time … Continue reading →

A new view of the origins of Unix

Posted By Greg Lehey

Warren Toomey has written an article entitled The strange birth and long life of Unix. It's good reading, and it gave me an insight that I didn't have before. I know Warren has researched this stuff carefully, and even apart from that it also has a ring of authenticity about it. An excellent addition to the collection of Unix history.

More TV recoding errors

Posted By Greg Lehey

I've been following the TV reception problems for some months now. I'm gradually coming to the conclusion that there are several issues, few of which are related to my hardware (which is what I originally thought). In particular, there are some recurrent programmes that consistently fail, while others record well. Many recordings are fine most of the way, and then suddenly fail catastrophically, and it seems to be at least somewhat related to date and time. All this points to some kind of interference. At some point I'll move the information to a database and do some analysis. But things aren't that simple.

USB and eSATA: more pain

Posted By Greg Lehey

Started a routine backup of my photos today. I back up to an external disk, which should be connected by eSATA, but I've had trouble with that: hot plug doesn't seem to work The disks also have USB interfaces (of course), but I've had trouble with that too. So until I sort out the eSATA hot plug issues, I've been backing up to a system where I don't care so much if the system crashes. Currently that's Yvonne's system, lagoon. But today things didn't work as expected: Dec  2 11:19:16 lagoon kernel: da0 at umass-sim0 bus 0 scbus0 target 0 lun 0 Dec  2 11:19:16 lagoon kernel: da0: <ST2000DL 003-9VT166 > Fixed Direct Access SCSI-2 device Dec  2 11:19:16 lagoon kernel: da0: 40.000MB/s transfers Dec  2 11:19:16 lagoon kernel: da0: 1907729MB (3907029168 512 byte sectors: 255H 63S/T 243201C) Dec  2 11:19:16 ...

I Received an Honorary Doctorate

Last weekend, I received an honorary PhD from the University of Westminster, in London. I have had mixed feelings about this since I was asked early this year. The best piece of advice I've read is: "It's a great honor, but it is an honor, not a degree."...

Walls as Security Theater

Posted By Bruce Schneier

Interesting essay on walls and their effects: Walls, then, are built not for security, but for a sense of security. The distinction is important, as those who commission them know very well. What a wall satisfies is not so much a material need as a mental one. Walls protect people not from barbarians, but from anxieties and fears, which can...

The lunatic fringe wakes up

Posted By Greg Lehey

It would have been too much to expect that the new NBN tower would get erected without a fuss. Wendy McClelland is up on her hind legs again, and has distributed another set of fliers (though not to me) warning of the microwave radiation tower, and again naming the owners of the property. It's very low on content, even less so than earlier ones; apart from the facts (the NBN will be giving information sessions), the only statement of any relevance is: ...and have connections to it by pulsing microwave radiation out at the people which radiates us all.

Four Scifis

Posted By Tim Bray

The electric-book-reading setup on the home front is in reasonably good order. The family shares an Amazon account and a Kobo account, and both those vendors are generous in the number of different reading devices you can have authorized at once. Lauren and I both use Android tablets of one size or another to read, and have few complaints. Also, were reading lots of books, so I should start reviewing a few. Just because this is a batch review doesnt mean that Ill always do that. Cops vs. Fabbers First, Rule 34, by Charles Stross. Stross is prolific; some of his books make me smile, others I dont begin to get.

The Second Draft of History

Posted By Tim Bray

The first, they say, is written by journalists. Then theres The 9/11 Wars, by Jason Burke, which dives deep on the conflicts launched back on That Day ten years ago and takes the story right up into 2011. I think its probably essential reading for anyone fascinated by these sad sequences, especially those who might want to have public opinions. Large parts will be unsurprising to anyone who followed the first draft closely; few of these stories remain secret. Furthermore, Burke doesnt do grand unifications; the strength of the book is in the attention to detail and a determined refusal to bypass the particular.

Full-Disk Encryption Works

According to researchers, full-disk encryption is hampering police forensics. The authors of the report suggest there are some things law enforcement can do, but they all must happen prior to a drive being buttoned up by encryption. Specifically, they say that law enforcement should stop turning computers off to bring them to another location for study, doing so only causes...

After a long and hard year, Liars and Outliers is done.
