Death of a fridge
Eight days shy of nine years ago, I got lucky when my new fridge I had purchased arrived hours after the previous unit died.

Fedora Linux on Lenovo T16 gen2 Intel
My 14” Lenovo T490 laptop broke, so I bought a 16” T16 Intel gen2 to replace it. I chose Intel instead of AMD at least because it was required for the highest resolution screen, and I think it mattered for memory configuration as well.

Deploying Mastodon on CentOS 9 and derivatives with podman

Deploying Mastodon on CentOS 9 and derivatives
I recently found myself setting up a Mastodon server. Elon Musk threatening to buy Twitter reminded me how fragile it is to live in walled gardens controlled by others. I know something of what it takes to run large-scale applications in the cloud. It’s my job. (Senior Director of Engineering, Platform, at Pendo.) I have some clue what it costs, and I’m not upset at being presented advertisements in Twitter. I even like being recommended content that I didn’t know that I wanted to find!

Delicata
About a year ago, my father introduced me to delicata squash. So tasty, and so easy to prepare! There are lots of recipes, but just to show how easy this is, here’s mine:

Dangerous Pumpkin Chiffon Pie
Part of my family heritage appears to be to risk illness on some special holidays. Chiffon is made with never-cooked egg whites, so there’s a real risk of salmonella from this pumpkin chiffon pie. But my grandmother made it, and I make it almost every year in her memory. My version uses less sugar, more pumpkin, and a bit more spice than hers, but it’s still the tradition.

Why I Quit Advocating Python
The Python 3 transition changed my perception of Python. My early experience of Python was good. Learning how to write good tests in Python made my Python code better. But the transition to Python 3 lost me as a Python advocate.

New Decade, New Treadmill
In January 2011, I started using a treadmill desk. Early on, I stopped using it for a year or so (I wasn’t keeping track exactly) but about eight years ago I started a habit of walking at about 3.5 miles per hour for about an hour every weekday morning. This past thursday morning, the 9th, the breaker tripped while I was walking. I reset it and tried again, and the instant I started the treadmill, it tripped again.

Cheap people go to the state fair
Two of the kids and I went to the state fair this morning. We got there before some things opened, and we visited mostly crafts and greenhouses, and ate some food. We skipped the midway. We left around noon and beat the worst of the rush to leave.

Return of the accidental digital archivist
One of my children asked a couple days ago about doing cryptic crosswords again, which led me to discover that Ron Sweet (Kegler)’s excellent crosswords were no longer available online. He had a site (though not at the URL I remembered) that said they were coming back soon. So I sent him an email asking how soon.

Making thermal isolating blocks for a kinematic mount
The Digital Dentist (Mark Rehorst)’s UMMD posts convinced me that I want a kinematic mount on my corexy printer I’m rebuilding from the skeleton of the piece of junk tronxy x5s I bought early last year. He recently blogged about some of the changes he as made, which included more stable thermal isolating mounting blocks.

Incomplete information
When I was young, my family had a subscription to Consumer Reports, and I grew up expecting it to be trustworthy. But I became an expert in a few things and discovered that on those topics, they were often uninformed and frequently misleading. A few years after I was married, my wife and I dropped our subscription because I no longer trusted them. Also, we had subscribed with a unique name, and as a result we got the impression that that they sold their subscriber list to anyone with a wooden nickel. The vast majority of our junk mail for the next fifteen years or more was addressed to the name that we had provided only to CR. This further eroded remaining trust in their intentions.

Putting the magic smoke back in
Last weekend, I was preparing my electric tractor for a new season of mowing, when I inadvertently touched the charging leads to the wrong battery tabs. The batteries for my tractor are from a totalled Chevy Volt, and they can source a lot of current. It’s what makes them so great for running an electric lawn mower!

How I Import into Discourse

The accidental digital archivist
I had other things I planned to do at the beginning of this year. Google had gone out of their way to push Google+ as a place for communities to come together, and communities in fact coalesced.

Saving more information from the Gpluscalypse
At the request of the group owners, I have archived the K40 G+ community content so that it’s not lost in the great bit bucket in the sky on April Fools’ Fools’ day. This community is continuing at makerforums.info and it would be nice to move from static files into importing all ~6GB into Discourse. Any Ruby devs out there willing to take some time to help me figure that out? I spent all of ten minutes reading the tutorial which doesn’t yet qualify me as an expert. ;)

When googling the error message fails

I’ve been doing some work on my home basement workshop...
I’ve been doing some work on my home basement workshop, and I bought a real¹ hammer drill for poured concrete. (Cheaper than renting!) For this project, I also have to drive some nails into wood at very inconvenient angles. (Retrofit can be harder than new construction.) I finally realized that I could put an impact socket in the hammer drill, set the drill to hammer-only mode (intended for chisels), and drive nails into wood.

Sony Xperia XZ2 Compact deal
My Xperia XZ2 compact is a good phone. Small enough to reach across, just barely enough bezel that holding the phone doesn’t inadvertently register as a touch at the edges, way more battery life than I need, Sony actually provides updates. Given the opportunity to do-over, I would buy it again.

Molten salt reactor progress
I’m so happy to see newer, safer nuclear power happening. I live near a nuclear power plant and am glad that I have a nuclear-powered car, but molten salt reactors are designed to be safe (no so-called “china syndrome”) and although this article doesn’t mention it, at least some of the designs use thorium salts, which do not generate weapons-grade materials as waste byproducts.

TLBleed leaks keys; careful with hyperthreads!
I followed +LWN.net’s link to lore.kernel.org this morning, and clicked on the first link I saw, with a fairly innocuous title. It seemed a slightly odd post for LKML, because disabling hyperthreading isn’t a new question; there have long been recognized workloads for which that’s a good idea. But that’s not really what it’s about.

Tronxy X5S becomes a frankenprinter
I’m slowly building a rather different printer on top of the skeleton of my Tronxy X5S. Previously I replaced the Z mechanism with a single motor and continuous belt driving synchronized single-start 2mm lead threaded rod, and milled alignment jigs to mount linear rail to the top of the Y axis and front of the X axis extrusion. Today I finished milling a set of gantry mounting plates out of 1/4” (6.35mm) aluminum plate to attach the X gantry extrusion to the Y linear trucks.

Crypto-Christians In Tech
I have very rarely been “dissed” to my face for being openly Christian. I’ve certainly been present to listen to others complain about various classes or factions of Christians (“those fundamentalists…”) but in my admittedly limited experience, honestly, the rudely anti-religious or anti-christian are not more prevalent than the occasional thoughtless or selfish Christian. I have not yet visited anywhere that really experiences religious persecution!

Can I use bare linear rail for extruder?
As I collect parts to upgrade my printer, I am struck that the 450mm long MR12 linear rail I bought seems stiff. It’s not clear that I should bolt it to a length of 2020 extrusion, if all it is holding up is a few hundred grams of extruder and an MGN H carriage. Does anyone have experience building a corexy printer using linear rail itself for X, without the added inertia of bolting it to something else like 2020 extrusion?

Howard Precision off cuts
A lot of the off cuts in their random bin are bigger than pieces in eBay stock assortments I’ve seen. $1.75/pound plus shipping is a pretty good price for hobbyist stock! They are clearly oriented towards professionals, so they don’t even take credit cards or quote shipping online, but it looks from my quote that they round up the weights on the web inventory so that there won’t be a nasty surprise in the quote.

Manual MESH_BED_LEVELING with Marlin 1.1.8
[Edit: solved] Manual MESH_BED_LEVELING with Marlin 1.1.8 does not appear to work at all for me. I have tried with both M420 S1 and M420 S1 Z5 in start code. I’ve tried printing from SD and from pronterface. In pronterface, I definitely see the printer reporting the rather non-flat bed configuration I have stored in EEPROM as well as that bed leveling is on and (for Z5) the fade height of 5, and I don’t see any errors printed, but I see no adjustments actually happening when I try to print, and I’m still grinding filament instead of printing at the high points of the bed…

TI calculators in education
I hate the TI calculator virtual monopoly in education. We got a Casio graphing calculator for our daughter. During a test, it started throwing errors. Confirmed not user error not only by the teacher but also by my wife, a math PhD. Even a hard reset didn’t clear it. The only thing that made it go away was clearing all device memory. Google search auto-completed the error, so it’s relatively common. No firmware updates appear to be available from Casio.

Replicape: Run cooling fan only when necessary?
Is it possible to configure one of the four replicape fan drivers to run whenever steppers are turned on? I have an 80mm 12V 2W fan I’d like to use to cool the replicape when the steppers are on (because I want to exceed 0.5A), but it would be nice to turn the fan off when the steppers aren’t being driven. (If that’s in the configuration docs, my apologies for missing it.)

Replicape fan voltage
I am pleased to see that Replicape sends 12V to fans and sensors. My 24V nozzle heater cartridges haven’t arrived yet. I see that (M303 PID tuning) has a P1 parameter for pre-calibration for high power heaters. I’m hoping that protects me from burning out the 12V 40W heater cartridge while I wait for the 24V cartridge to arrive. (Trying to avoid having to use two power supplies when I install the replicape on the Tronxy X5S.)

I tried FreeCAD last night, following up to a thread from the OP. It’s clearly very powerful and if I spent lots of time learning what to expect I could work very quickly in it. I’m moderately experienced in OpenSCAD, and of course FreeCAD is very different; that’s basically the point. Since I’m new to FreeCAD, my early impressions might be completely wrong. But I thought I’d share them.

Volunteer president
Huh. The new Amtrak president is a volunteer — unpaid. I love airplanes and don’t despise commercial air travel but I would totally travel by train sometimes if they could fix the scheduling nightmare where freight trains taking a month to go coast to coast still have priority over passenger traffic, and would sell connected tickets. Right now if you want to buy travel through a hub it’s two separate tickets and if they are late and cause you to miss the next train on your itinerary, so sad for you buy a new ticket. Getting stuck in DC because the train was its typical 10 hours late from NC to DC isn’t workable. Basically you have to schedule at least an overnight with a liberal cancellation policy in DC to make that work.

Last few hours for the $399 price for this open source, open hardware programmable power supply: The pre-order price after the campaign will jump from $399 to $450. The final retail price will be at least $499, possibly higher.

H24005 power supply will be made!
The H24005 passed its initial funding goal. When it hit its first stretch goal and got an encoder knob it resolved one of my biggest usability concerns. When it hit its second stretch goal the isolated USB and ethernet ports addressed my other major concern. It’s only -42- 41 full kits away from the third stretch goal of adding a low power, high resolution, low noise mode.

Fridge temperature data: Handling heat
Last night, at about a quarter past ten, we took home-made stock out of the pot, barely less than boiling, and put it in the fridge. This morning, I was curious what putting about 4 quarts of very hot liquid in the fridge did to temperatures in the fridge, so I graphed the last 12 hours of temperature sensor data.

Looking for low VGS MOSFETs
Hey lazyweb, I’m looking for N-MOSFETs that will switch 20V or more (VDS) with a VGS 3.3V or lower, so that I can use Real Computers for my intranet of things. I found a reference to PMV16XNR with RDSon under 0.04 ohms at 1.8V VGS and $0.16/unit in 100s. It’s available only in SOT23 though.

Value of comprehensive test coverage
My first experiment with achieving 100% line coverage caught two bugs in the last three lines covered. They were both trivial bugs in error handling. They happened because I had roughed out some ideas early in development about error handling, but did not have anything driving me to recognize when development had invalidated early assumptions—until I thought about how to test those error cases.

NC Quick Pass bad service terms
A few times per year, one or the other of our family vehicles travels on our local toll road, and I get a ~$5 bill in the mail. Each time, I think about spending the money on transponders for the cars, and each time I read the Terms and Conditions of a transponder account and am reminded how inequitable they are. Among the absurdities presented is that as a transponder owner, I would be responsible to monitor my account on the web site to see whether my balance has fallen to a level that requires replenishment, with no responsibility on the toll operator to inform me, though they can charge me for failing to notice independently and replenish. That’s crazy stupid.

Digital infrastructure security boondoggle
Obama wants to secure our digital infrastructure to the tune of $19B? How about we start by not trying to force back doors into software and infrastructure, for a grand total of $0 budget requirement, and continue by discontinuing the archaic, ridiculous, and utterly meaningless registration system for “exporting” encryption that encourages companies to avoid encryption to reduce product cost, for an additional savings over our current spend. Maybe that would both help make funds available to improve the digital security of our physical infrastructure, and make it more likely that the software used to manage our physical infrastructure is strong “out of the gate”.

New Fridge: Data
The new fridge has shorter, smaller temperature cycles than the old dead GE fridge. Measured temperatures in the fridge are still substantially higher than the setpoint of 36⁰F (2⁰C); measured temperatures in the freezer substantially higher than the setpoint of 0⁰F (-18⁰C). And the manual contains no instructions on changing the setpoints. It says where the buttons are (duh, those are obvious) but not how to use them, and the installers said that once set, the setting could not be changed for 24 hours (nothing in the manual about that).

MIG Home Repair
A MIG welder was not the right tool for the job, and I’ve never tried welds quite like this before. It’s not perfectly straight; the attached pulley wobbles about 2mm or so at the outside. I thought I had to grind down the bead on the outside to fit, and it turns out I needn’t have done so and may have weakened it a bit doing so. But it’s probably stronger than when we bought it, and it works, even though the weld is ugly.
-
Short Warranty Rationale
The broken crank from my +ProForm elliptical trainer. Terrible welding. Only a tiny bit of the welding was actually a through weld. Mostly cold welds rusted through. This is definitely a manufacturing defect. No wonder ProForm (ICON) offers only a 90 day warranty. Paying over $110 for a replacement for this piece of junk part is clearly not a winning idea.
-
ProForm service fail
After less than 5 months in service, our ProForm elliptical trainer died. The crank was clearly flawed, and it broke while my wife was exercising. The 90-day warranty was two months out of date. ProForm wants over $110 for a replacement crank (probably costs them about $2). Not that I can get the crank off the crank arm to replace it, since the screw heads are stripped. So even if I wanted to throw good money after bad, it would be a challenge.

CentOS 7.1 update disabled NFS

I’m guessing NetworkMangler isn’t very well tested for BOOTPROTO=static but I am a little surprised that it would make this basic a mistake. (And here I was actively trying not to be a Luddite.) Now that I’ve fixed or worked around those two issues, I’m curious to find out what else is broken.

Bad Schlage latch design
The outside latch on my front door doesn’t work to open the door. It’s not a security issue since the problem is that it doesn’t open. This may be a feature since it teaches the kids to ring and to answer the doorbell. However, it annoys my wife.

Trust, but verify
I have an old recycled server (about six years old) that I pressed into emergency service due to a hardware failure a few weeks ago. But it’s loud. So I got some replacement quiet fans for it. Much cheaper (and, I hope, more environmentally friendly) than buying a new system. But there’s no standard for wiring for fans, and the datasheets don’t all agree.

NASA to Launch Satellites into Powerful Magnetic Explosions
Headline looks over the top, but really it isn’t. What we don’t know about magnetic reconnection may kill us; at least in much of the developed world where we depend on the power grid functioning for our basic food infrastructure. This is essential research that may save civilization from catastrophe some day in the not too distant future. It also might help clear the way for successfully using nuclear fusion to generate clean power, which might end up an essential part of protecting our planet for future generations. Unlike populating Mars, this is truly important work NASA is doing.

Superfish adware and DMCA?
Aren’t SSL certificates (especially system-wide certificates) used as a “technological measure that effectively controls access” to rights-protected works? I’m curious why #Superfish wouldn’t be violating #DMCA Section 1201(a)(3)(A) by decrypting encrypted works “without the authority of the copyright owner” since I don’t see that there’s anything preventing it from doing so for works covered under the DMCA. Does one or more of the exemptions apply here? The DMCA is such a twisty maze…

Joule Thief
Made a “Joule Thief” with my son this morning. Able (barely) to light a 3V white LED from a very depleted AA cell with 0.66V remaining. He insisted on using a relatively fresh D cell. Since that is pulling about 50mA now and will pull less as the battery wears out, and Duracell’s datasheet indicates 50 hour life at 250mA constant current, I figure he has at least 250 hours of illumination available. Since it has only a momentary pushbutton switch, I have my doubts that he’ll have the patience to use up even the one battery—at least unless he replaces the switch.

Dual palindromes
My almost fifteen-year-old car today simultaneously turned over 150051 miles on the odometer and 299.2 miles on the trip odometer.

I remember noticing several before hitting 100000 miles though.

Generating an ICC file for my monitor

I would hope there’s a program I can invoke, but it’s clearly not any of the programs in colorhug-client since I tried those. Any enlightenment? Thanks!

If it looks good, I’ll do two more strips for the other shelves and then wire them all into the controller, attached to the extra 12V power supply I installed in the under-cabinet fixture I converted from halogen to LED. The reason for the dimmer is that I just want to add a pleasant glow in the cabinets, not make them very bright.

Learning KiCad
Learning KiCad has been interesting. Some things have been easy to learn after running through the tutorial. Others have taken some searching. Finding the right component is hard (like finding vertical electrolytic capacitors); the libraries are inconsistent and hard to browse. Figuring out how to place mechanical holes (NPTH—non-plated through hole) for “panelized” boards that snap apart took several google searches, and that was after I found a python script to run to panelize a design. The graphics handling is so 1980s, in that it draws garbage and expects you to regularly manually refresh to get rid of visual garbage on the display.

Intel Edison pricing fail
I’m confused by Intel Edison. The cheapest way to get started doing anything involving interfacing it with the real world, as far as I can tell, is a $65 SOM plus a $24 breakout. About $90 for a single unit. The benefit over BeagleBone Black ($55) is wifi and bluetooth included in the Edison SOM. The BBB has more I/Os and two “bare” 200MHz PRUs; the Edison has one 100MHz PRU running an unspecified RTOS. BBB has been (despite its process speed and I/O advantages) a distant second-place in the market to the mostly-inferior (except in video performance) Raspberry Pi which is slightly less expensive. (I know, limited availability hasn’t helped BBB…)

Mitigating monopoly
Concerned about the monopolistic potential of the TWC-Comcast proposed merger? I’m making a wild guess that checking your address and signing up for updates for Google fiber is a practical step you can take towards mitigating its effect on you, and maybe towards pushing towards more widespread rollout of internet connectivity with reasonable throughput…

Who Should Store NSA Surveillance Data

Test-drove my electric lawn tractor
Drove my newly-converted-to-electric lawn tractor up and down the street today to limber the new belts and test how much power it drew running without the mower deck installed. As little as 35A downhill, as much as 85A uphill. The belts are apparently a little tight and so it doesn’t want to come to a complete stop, which is disconcerting. I hope that gets better with time. Neighborhood teens with a high school assignment to build something using renewable power this coming semester enjoyed looking at it. ☺

KitKat ART runtime works
Last night I finally got around to trying the #ART runtime on my GPE S4 running #kitkat . So far, I have found only one application that breaks.

KitKat update on GPE S4
After the upgrade to #KitKat on my GPE S4, PowerAmp can still play the music on my microSD card (/storage/extSdCard/Music) and the magnetometer in the phone works more or less correctly for the first time since I bought the phone, so Google Sky Map is usable without switching to manual mode, and compass apps work. (Yes, I “recalibrated” previously, over and over, to no avail.)

I’m wondering why this shows up as a single drive and not two drives.

Done right, this would be a great device for a Linux system. Done wrong, it would be a stupid device for any system. The mention of having to unlock the device with a special “USB key” makes me fear that it’s done wrong. Anyone know?

Baneheia, Kristiansand Album
Baneheia is a large park on an outcropping of rock over Kristiansand. Kim suggested we visit, and I’m glad I listened. In the late 1800s, General Joseph Frantz Oscar Wergeland sent his garrison soldiers out to beautify “that disgusting heath” by planting (eventually) over 150,000 trees and otherwise turning it into a park with reservoirs for Kristiansand. There were walking paths, but we also wandered off the paths through the ever-present blueberry scrub.
-
Kristiansand: Vest-Adger museums
Vest-Adger is a set of museums; this one is an open-air museum roughly 2km east-northeast of Kristiansand. They have one city section and two rural town sections (one more rural than the other). Some of the houses (when we were there, mostly in the city section) are open. Inside, there were lots of themed historical displays, including early telegraphy and telephony with old equipment and examples of undersea cable from different eras, history of shipbuilding and the shipping business (in a house previously occupied by a ship captain), and a typical general store which had cobalt blue paint that naturally contained arsenic and functioned as an insecticide—useful in stores and kitchens generally before the advent of widespread refrigeration.
-
Kristiansand Album
Our last port of call on the cruise was Kristiansand. The cruise line substituted Kristiansand for Olden after we booked the tickets, and I initially felt disappointed. Now I wouldn’t have wanted to miss Kristiansand, though I’d also like to see Olden some day…

Sunsets at sea

Bergen
Our second-to-last stop was Bergen. We visited Troldhaugen (Grieg’s summer home) in the morning, then after lunch near the fishmarket took the funicular up to Mt. Floyen, then back down to visit the Hanseatic Museum and walk through Bryggen generally.

Geiranger: Westerås farm to Løsta viewpoint
In Geiranger, Kim and I hiked up a trail to Westerås farm, then up to Løsta viewpoint 550 meters above the fjord. OsmAnd with Norway maps loaded was useful finding the trails since google maps couldn’t be bothered to help with that part.
-
Geiranger Fjord
I got up at 3:30 AM to take pictures in Geiranger Fjord after sleeping poorly, and my only two regrets are not waking up at 2:30 or 3:00, and not wearing warmer clothing, as the chill wind was howling through the windows I opened on the pool deck. (The upper deck was closed due to the high winds.) The winds were so strong that most of the multi–shot panoramas I attempted failed because the camera was being buffeted by the wind.

Geiranger: Westerås farm lunch
Lunch at Westerås farm: 400 NOK ($80). The porridge was rommegrot; Kim had entirely forgotten eating it as a child, but memories flooded back as she ate it, so it was worth the price. Also, after hiking 550 meters up and 350 meters back down, we were hungry for lunch.

Tromsø's cathedral and not-Tromsø's not-cathedral
Tromsø’s “Arctic Cathedral” (not a cathedral, and across the bridge in Tromsdalen) and Tromsø Cathedral. Both beautiful places that I can’t effectively convey in photographs and where I wish we could have spent more time.
-
Tromsø album
On the cruise, our next stop was Tromsø. We walked around the city center, took the cable car up to Fjellstua, visited the “Arctic Cathedral” and Tromsø Cathedral, bought some gifts back in the city center, then walked through Tromsø University (the northernmost university in the world) and down to the Tromsø Botanical Gardens.

Ålesund album
Our first Norwegian port on our cruise was Ålesund. We didn’t get to see everything we wanted to (for example, we didn’t get to Ålesunds Museum) but we did climb Aksla to Fjellstua viewpoint, buy a prepaid SIM for my phone, and go see Sunnmøre Museum (I’ll post another album with those pictures).

A war the Pentagon doesn't want
Robert H. Scales, a retired Army major general, writes: Perhaps the United States has become too used to fighting third-rate armies. As the Israelis learned in 1973, the Syrians are tough and mean-spirited killers with nothing to lose… Dwight Eisenhower … resisted liberal democrats who wanted to aid the newly formed nation of South Vietnam. We all know what happened after his successor ignored Eisenhower’s advice.

John Kerry's Lie
If any country on earth struck American bunkers, airfields, or artillery batteries, virtually every last American would understand that as an act of war… I guess Neville Chamberlain’s Britain needn’t have declared classical war against the Nazis, just “degraded their capacities,” like the Japanese did to us at Pearl Harbor, where they didn’t put “boots on the ground.”

Chromebook auto-update downside
The dark side of auto update… I have a 500MB date plan because I typically use between 100MB and 200MB of data per month. About a month ago, I tethered my chromebook for a few minutes to check a few web pages, and it quietly downloaded a 150MB update. Coupled with a little extra data usage from posting pictures on a short trip to NYC, I ran out of data for the first time ever. Then this month, while visiting family away from WiFi, my Google phone downloaded it’s own (you guessed it) ~150MB update to Android 4.3. Combined with (again) posting a few pictures, the same thing happened again. Next month is LinuxCon/Plumbers. Do I need to give in and increase my data plan?

I installed Windows 7 in order to try out DxO Optics Pro. I’m impressed by DxO Optics Pro so far. Windows 7, on the other hand, has so far: trashed a USB hard drive so thoroughly that even testdisk couldn’t find any contents, required reboots to install essential updates about three times per day (most of the time I’m using Optics Pro, Windows is complaining that I’m behind already, minutes after installing the previous batch of “important” updates), required at least two reboots (maybe three?) in a row for one set of updates, and is generally reminding me why I don’t use Windows by preference. What a mess.

Any other recommendations for art photo printing, either national or local to the Raleigh area?

I don’t see that any of them offer UV barrier film on foam mounted prints, but I haven’t researched far enough yet to be sure.

In-camera GPS
I have a +Sony SLT-A55V camera. The “V” means that it has a built-in GPS, which I am finding surprisingly helpful.

Given the option to go back in time and “do it over”, I’d make the same choice. A few minor gripes, though…

Surprised by git fetch
+Git keeps surprising me. Sometimes this is good. Sometimes I’m less convinced. For example, I have some bare repositories that I want to keep up to date with upstream versions, against which I’m running some reporting scripts. Of course, since they are bare repositories, I can’t “git pull”; I have to “git fetch”. But it is much less obvious that “git fetch”, while it will fetch changes to existing refs, by default will not also pull in new upstream refs unless I “git fetch origin +refs/heads/:refs/heads/” because when you clone into a bare repository, it doesn’t set up the “fetch” configuration for the remote. Could someone tell me why it is obvious that cloning into a bare repository should set up the origin remote including its URL but leave off the default fetch specification that you would otherwise get?

(As before, this isn’t just about pilots, as this is merely what has been done to many others now happening to pilots as well.) When officers charged with law enforcement act in bad faith, they create disrespect for the law, destroying the rule of law worse than most criminals.

The Feed Reader Reviews: Newsblur

Trying the ARM chromebook
I decided to try out the arm chromebook. It’s inexpensive and light and has reasonable battery life. With Crouton, I can have a reasonably complete Linux install running on it without too much trouble. Keyboard isn’t great but is usable so far. I’ll see how I feel in a month or so.

Annals of the Security State: the Airplane Stories Continue
James Fallows has been posting stories recently about how the DHS has been intimidating law-abiding private pilots. He has also said: `To be clear, I am not saying that the pilot population is being singled out for stop-and-frisk treatment. I am saying that this is another window into what the open-ended War on Terror and War on Drugs have wrought.´

Newsblur usability update
Update on #newsblur after using it for a while: The UI still isn’t as polished as #reader but it has improved, and the Android app went from essentially unusable to definitely usable. In both the web UI and Android app, the main problem is that it doesn’t prefetch in the background, so each time you come to the end of a batch of fetched stories, it’s a long (often 3-5 second) wait for the next batch. That’s getting in the way of it really supporting my need for spinning through lots of news fast; I can’t average a couple stories per second when I have to wait 3-5 seconds every ten stories.

Google Photos automatic enhancement

G+ keyboard navigation fail
My gripe about the new G+ layout is that the “Home” key doesn’t go back to the top. Since I still have my j and k keys to go through the stream in the same order that the vertical layout had, so far I’m finding the new layout a workable solution for the #whitespace problem.

Patent abuse is not a new problem
Alan Cox
“That it is the opinion of this House that the time has arrived when the interests of trade and commerce, and the progress of the arts and sciences in this country, would be promoted by the abolition of patents on inventions”
From the debate in the UK parliament in 1869, where they were worried about the inexorable rise of patents - there being 250 in 1825 but now 2292 in 1867….
Its a fascinating read. The same problems we have today (on a vast scale) were present then and beng complained about - including the fact it had been meant to help manufacturers but was now hindering trade
And boy does this still sound familiar
“There was an army of mechanics and chemists on one side, and the other, and they were examined before a jury who knew nothing of chemistry and mechanics and before a judge who might be even in a worse position, because he might think he understood it when he did not”
“The bias of the courts being from the beginning in favour of patentees”

Trying out T-Mobile
I decided to give the new T-Mobile plans a try, since my wife and I each use less than 200MB/month of data, and so we will easily fit in the 500MB/month base plan, even if we use the included hotspot data feature a bit. The T-Mobile folks are clearly still getting used to the new world order. I dropped by the local store yesterday to ask some questions (since the web site was giving many 404’s last weekend) and figured that today it would be a quick trip to pick up a pair of SIMs and test things out. Ended up taking over an hour, none of which was waiting for other customers.

Grammar, a Victim in the Office
My compositional bête noire is not, generally speaking, the grammatical gaffe (although there are a few to which I occasionally fall prey), but rather a tendency to prolix, convoluted prose, full of indefensibly subordinate clauses. I am overly fond of using semicolons to separate independent but logically-connected sentences; although this construction is generally grammatically defensible, it requires excessive work from my readers (if, indeed, after the first few sentences, I have any left). -

Plumbum: Shell Combinators and More
Interesting use of operator overloading to reproduce bits of shell syntax in python. I haven’t tried playing with it yet.

SOPA and PIPA analogy
Oskar Austegard
“Assume there’s a corner store in your neighborhood that rents movies. But the movie industry believes that some or even all of the videos in that store are unauthorized copies, so that they’re not being paid when people watch their movies. What should be done?
“SOPA/PIPA don’t aim at the people trying to get to the store. SOPA/ PIPA don’t penalize or regulate the store itself. SOPA and PIPA penalize us if we don’t block the people trying to get to the store.
“The solution under the proposed bills is to make it as difficult as possible to find or interact with the store. Maps showing the location of the store must be changed to hide it(1). The road to the store must be blocked off so that it’s difficult to physically get to there(2). Directory services must unlist the store’s phone number and address(3). Credit card companies(4) would have to cease providing services to the store. Local newspapers would no longer be allowed to place ads for the video store(5). And to make sure it all happens, any person or organization who doesn’t do this is subject to penalties(6). Even publishing a newsletter that tells people where the store is would be prohibited by this legislation(7).
“This is what SOPA and PIPA would impose in the online world. It’s very different than targeting the owner of the video store directly. The obligations to made websites hard to find apply to all citizens and businesses. Each one of us is subject to punishment and fines if we don’t fulfill these prohibitions. And, because SOPA/PIPA create a new regulatory structure, we become subject to punishment without the due process protections citizens normally enjoy.”

She inscribed several finished copies as gifts for family members, so next we need to find appropriate envelopes and take a trip to the post office.

Calling a service technician to change a lightbulb is idiotic and would cost a significant portion of replacing the entire unit.

Finally signed up with LibraryThing
Finally signed up with LibraryThing.com a few days ago. My USB barcode scanner arrived today, which sped up the cataloging process a bit. I’ve seen complaints from folks that their scanners “don’t work”; I have to wonder if they are scanning the UPC code on books where the UPC doesn’t encode the ISBN; for years, the ISBN barcode printed on the inside front cover.

Trick or Treat
An hour and a half to cover one block trick-or-treating with three kids. We walked on road and driveways instead of lawns which made it a much longer walk than many of our fellow trick-or-treaters. And then I let the kids eat only one piece of candy each before bed! So it actually counted as exercise…

Careless recruiters
I’m always amazed that many recruiters don’t seem to proofread their emails. I’m looking at one now that’s missing critical words and phrases, and has sentences that just don’t parse. I don’t notice any spelling errors, unless you count not including words at all as the ultimate spelling error, but it doesn’t leave a great impression.

An Ode to Dennis Ritchie
This article gets a few trivial points wrong (for example, missing C# being a close derivative of Java) but I think it does a good job of explaining for a more general audience why many of us cared so deeply when we heard of Dennis Ritchie’s passing.

Motorola indecision
I just discovered that I can’t use the microsd slot in my wifi Xoom, even though the kernel supports it and it was advertised to me as containing a microsd slot that would support up to 32GB microsd cards, because Motorola can’t decide where in the filesystem to mount it. Words fail me. (Well, no, actually, they don’t; “false advertising claims” and “bait and switch” come to mind.)

The Saga Of the Microwave Turntable
Months ago, my eldest daughter accidentally broke the glass turntable tray in our microwave oven. I quickly googled the part and determined that it was almost $80, plus shipping and handling; I showed her the price, and inverted a dinner plate in the microwave to hold food up at the right level, though the food no longer rotated. I meant to order a new one quickly, but somehow there was always too much else to do.

New Treaddesker
In December, Steelcase loaned rPath a “Walkstation” for a week. This is a basic treadmill with a desk attached that has motorized height adjustment. Unfortunately, it is very expensive ($4200 is the lowest I’ve seen), maxes out at 2 miles per hour, has a small tread area, has no incline capability, and the retractable console for controlling the treadmill has sharp edges. It beeps loudly whenever you press a button, and the treadmill isn’t the quietest I’ve heard.

OpenOffice.org E-Publishing

So far, he has listed the book on lulu.com in hardcover, softcover, and PDF download formats. Recently, he decided that he wanted to offer it in various e-book formats as well.

Why I Bought Samsung Galaxy Phones
Briefly:
- Started to play with the Galaxy S (GT-I9000) phone Harald Welte reports that Samsung is going a good job of living up to its GPL requirements for its Linux-based Android phones, including the Galaxy S series.
- GPL violation reports in HTC G2 Android phone Harald Welte discusses a long string of GPL violation issues on HTC's part, including their willful and acknowledged flouting of the GPL.
- HTC Willfully Violates the GPL in T-Mobile's New G2 Android Phone Steve Schultze quotes HTC directly admitting that they do not follow the GPL, pretending that withholding source code is acceptable under the GPL.

The Linux Programming Interface: Preview

Math, Amtrak Style
I had a page open to check the progress of an Amtrak train, so that I could know when to pick up a passenger. Not a lot of info was available. As of 8:30PM, it just said “on time” for 9:00PM (though the timetable said 9:13PM instead of 9:00PM, just to keep things interesting).

Archos 7 Home Tablet: First Impressions
In part because my children are perhaps not quite so careful with CDs as I am, I ripped all my CDs (at least, all that will still read!) to flac, ogg, and mp3 files. The second half of the project was to get a media player that could play all those files – preferably over the network from my main server so that I don’t have to copy files onto an SD card every time I get a new CD and rip it.

Pleasant Surprises, Part 2
I not so recently mentioned that I was pleased with work that Jet City Devices did to my wife’s smartphone. What I didn’t know at the time was that while the screen was no longer cracked, the touch sensor was not working correctly; it was only occasionally registering touch on some parts of the screen, at best.

Pleasant Surprises
My wife found her smartphone screen cracked recently. AT&T told her to suck it up and buy a new phone, and the local independent shop couldn’t fix her phone. I had a great deal of trepidation about sending the phone off to some random place I googled, but in the end sent it off to Jet City Devices in Seattle.

Review: The Graveyard Book
A Christmas gift some years ago of The Dream Hunters introduced me to Neil Gaiman’s work. As an amateur of folk tales, I was entranced and delighted by the beauty and craft of The Dream Hunters, and then started reading earlier works in the Sandman series; my introduction to the graphic novel. Neverwhere and Stardust next captured my attention, followed quickly by most of the rest of Gaiman’s books.

Scary Halloween: A Public Service Announcement
My wife and I had everything planned for Halloween; I would take the girls trick-or-treating and she would hold down the fort. My first hint that the evening might take an unexpected turn was when she called to mention that she smelled something funny, and she thought that this time it probably was natural gas, not a stale dishrag like last time. I was skeptical, until she called me a few hours later to say that the smell was a lot stronger in the (gas) furnace room, that the kids were buckled into the car, and that I was going to be coming home to deal with this while she and the kids went to supper.

Ken VanDine and I flew up to the Detroit area yesterday to give a talk last night at the Michigan!/usr/group. As you can probably tell from the UUCP-inspired name of the group, it has been around for a while – at 21 years old, it’s old enough to drink!

Adventures in LVM2
I’ve been an old-school die-hard gimme-those-old-time-primary-partitions kind of geek for a long time now. Even extended partitions bother me, especially when partial drive failure makes otherwise unaffected partitions disappear. So while the flexibility that LVM provides was enticing, I was frankly a little uncomfortable putting LVM on my system, especially after a hard drive crash.

Moving to Mercurial
Before we ever announced Conary, we tried converting from CVS to Subversion. We were not happy; the conversion wasn’t great, but much worse was the corruption in the db back end (I know there’s a filesystem back end now); we decided that we could live with CVS at that point, and that it just wasn’t worth the trouble to change. I understand that Subversion has improved since then, but one of the things we decided was that if we were going to change, we really wanted to move to something that allowed disconnected operation (for those cross-continental plane flights…).
