Sorry, I should have added that I have it building both libraries using files that were compiled using fpic. It seems to work fine, but I noticed that one of my executables is 1.5% bigger and another is 3.3% bigger when they are linked with the static library built from files that were compiled with fpic.

On the flip side, having had to maintain over a few hundred libraries and tools across multiple flavors of unix and Linux I came to appreciate consistency. Autotools had its flaws, but it was nice for the builds to share conventions. As other build systems came into play it became inconvenient as a maintainer to have to figure out how each one did its magic and how to get it to do something beyond defaults (send in specific paths, install locations, etc...). But the maintainers aren't the only users - there's something to be said for ease of configuration. Autotools isn't awful but I'm sure there's something cleaner. Even so, I remember what a breath of fresh air it was when X11 moved from xmkmf to autoconf - I sure don't miss IMAKEFILEs. > > > Now I can make more complicated build scripts, including shell calls to > > dpkg for dependency management.

The name of the tool was 'tup'. The main disaster of his idea is that he can establish the build correctness without loading the entire dependency graph into the memory, just by checking the file stamps. It sort of works if you just build only one binary out of of a bunch of files, but if you produce multiple binaries that share an object file, then it breaks down. Also the tool has built-in knowledge that all object files are produced by the build and it saves you from having to write the 'clean' rule. Wonderful. What about vendor-supplied object files? Yes, not libraries, object files... they do exist. His tool will blissfully delete them. The main thrust of his article and presentation was "look how fast my tool is on this edge case." No mention of correctness at all. Make has some syntax warts, but then everything that survives for thirty years is bound to have some. What it gives it the staying power is that it is an rule-driven expert system configured through a functional programming language. The rule driven expert system simply says that 'if you need X and have Y, this is how you get X from Y.' Of course, wrapped in the temporal dependency (if you have the rule mentioned above and Y is newer than X, rebuild X). The functional programming language aspect is visible in the immutability of the variable assignments with respect to execution of the rules. Yes, you can append to CFLAGS, but once you start executing the rules, the CFLAGS (global) is immutable. Second, it is visible in the way data is processed for targets. Here is a snippet from one of my standard makefiles: SOURCES=$(wildcard *.c) OBJECTS=$(SOURCES:.c=.o) DEPS=$(SOURCES:.c=.d) ... clean: @$(RM) $(OBJECTS) $(TARGETS) $(DEPS) ... You don't go iterating over C files, to count them. Or go looping over each C file replacing the extension one by one. Make was the original DSL (domain specific language). That topic is 'hot' again.

Free Geek Twin Cities' purpose is threefold, 1. to reuse electronics(computer specifically), 2. to reduce e-waste by responsibly recycling electronics(not computers specifically) that cannot be reasonably reused and 3. to work to bridge the digital divide and increase computer literacy. as part of 3. FGTC will donate workstations to organizations that work to increase digital literacy(admittedly a very broad scope). It is true that FGTC does not directly donate computers to individuals, the nominal cost FGTC charges at the thrift store goes to cover the operating costs of the organization. Computers need power to run, buildings need heating/cooling, internet access is needed to install and update and OS and none of this is cheap. and yes, I volunteer at Free Geek Twin Cities.

I was thinking I'd build one of the libs and remove the object files and then rebuild them. I added a subdirectory and it looks like that will work. Before I did that I looked at autoconf and automake again. I think there's kind of an impedance mismatch for what I'm working on and those tools. Most of the code I'm working on is in the back tier which users don't have to build. The library and two executables that users are expected to build are all in one directory. (I'm not sure I'll export the new directory I added for the shared library since I'm not sure if anyone besides me wants that.) So I think my need for something like autoconf is small. Probably what I should do is port the makefile to Solaris or another platform and include that new makefile in the distribution. -- Brian Wood Ebenezer Enterprises - so far G-d has helped us. http://webEbenezer.net (651) 251-9384 -------------- next part -------------- An HTML attachment was scrubbed...

Spinrite is payware, but it does work for finding bad blocks on the underlying disk. http://www.grc.com/sr/spinrite.htm The site is a bit dated, but the tool is good. Only downside I've found is that if you have a bad spot on your disk, the tool can spend a *very* long time trying to recover data from it even if you know for a fact there's no data there you want to recover (such as in the case of a disk you don't have any data on you care about). There's no way to tell it to just mark certain sectors bad and not try to recover data from them. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com From mbmiller+l at gmail.com Thu Apr 4 14:52:31 2013 From: mbmiller+l at gmail.com (Mike Miller) Date: Thu, 4 Apr 2013 14:52:31 -0500 (CDT) Subject: [tclug-list] environment In-Reply-To: References: Message-ID: On Wed, 3 Apr 2013, Gerry wrote: > strings /proc/$$/environ That's interesting, but what is it doing differently from printenv?

If both blocks were readable ( *i.e.* were read from the disk, without the disk indicating any sort of error condition), but there was a mis-compare, then the data from the highest-numbered disk is copied to the other disk.

So the variable $ is the PID for the current (bash) shell as in... echo $$ ps aux | grep -w $$ So /proc/$$ is a directory with info related to the current bash shell and the file environ in that directory holds the environment strings. They seem to be delimited by null (NUL) characters. So this shows the environment strings: tr '\0' '\n' < /proc/$$/environ The strings command provides exactly the same output and it is easier to type.

You can do a read test with dd if=/dev/sda of=/dev/zero and see if that fails.

I tried to use it to recover data from a SATA drive and it blew up with a divide by zero. Tech support for spinrite just told me that it works best on IDE drives.

This will be a whole day (9:00am to 5:00pm) dedicated to working with and learning about the Raspberry Pi ! This will be hands-on, so bring your Raspberry Pi and follow along with your own Raspberry Pi! Here is the agenda so far: There will be an intro "class" in the morning (9:30 to 11:30). With step-by-step to get you started. Followed by a Q & A time. So bring your Raspberry Pi and learn the basics in the morning. For Lunch, I will order pizza for all who would like to go in on buying some pizza. You are also welcome to bring your own lunch or go somewhere else. In the afternoon I hope to have different session on Raspberry Pi topics: XBMC on the Raspberry Pi Raspberry Pi Programming GPIO in C and more hopefully... That is the plan so far! If you plan on going please sign up on the wiki. *** If you or, if you know someone, that has worked with Raspberry Pi and would be willing to present (or help) at the meeting please contact Me (Brian Dolan-Goecke) from http://www.goecke-dolan.com/Brian/sendmeail.php I am hoping to fine someone with experience driving motors and see some other interesting things that people have done with the Raspberry Pi. Thanks I hope to see you there! ==>brian. Be sure to order and get your Raspberry Pi today! You can get a "Maker Shed" kit at MicroCenter http://www.microcenter.com/product/402492/Raspberry_Pi_Starter_Kit (They had 2 in stock when I check earlier today. Be sure to select the Minnesota store in the drop down list in the middle of the page header at the top.) Here is more info about the "Maker Shed" kit http://www.makershed.com/Raspberry_Pi_Starter_Kit_Includes_Raspberry_Pi_p/msrpik.htm You can order from adafruit (they seem to have them in stock when I checked today) http://adafruit.com/category/105 They also have several additional accessories, and project for the Raspberry Pi. Jack Ungerleider mentioned you can get a Raspberry Pi here also http://www.mcmelectronics.com/ I am sure there are many more places on the internet if you look *** If you don't know what the Raspberry Pi is see these links http://en.wikipedia.org/wiki/Raspberry_Pi http://www.raspberrypi.org/ From susan.dawn.stewart at gmail.com Sun Apr 7 19:21:48 2013 From: susan.dawn.stewart at gmail.com (Susan) Date: Sun, 7 Apr 2013 19:21:48 -0500 Subject: [tclug-list] RPi Workshop Message-ID: <51AE1AE9-1166-46B4-B5F4-DF7E5B628E7E@gmail.com> Hello! A friend of mine & I decided yesterday we're going to attend the April 27th workshop. I still need to hop over to the wiki to sign up. Quick question: Without purchasing an entire "kit," what's the minimum necessities for getting rolling? I'm thinking: HMDI monitor & cable USB mouse USB keyboard 4GB SD card power supply & ??? Please add to my list of absolute minimum "essentials" & please let me know if any psu, with the correct specs, of course, will do... Adafruit sells a psu which they bill as "Linux compatible," or something like that, but I can't imagine that's much more than marketing hype. Forgive me if these questions have already been addressed, I've had a lot going on as of late & have been barely scanning daily emails. Truthfully, for now much of the chatter on this list is over my head - but that's EXACTLY why I want to play around w/the RPi. My friend is a windows-centric DBA @his work, but has some Linux experience. He hasn't done anything w/hardware for years. So I guess I'll be taking the lead on the hardware & he'll take the lead on the software. Feel free to tell me to go back & read the archives! Thanks in advance!

Check your current monitor (or even TV) for the kinds of inputs it has and use either the S-Video or HDMI or DVI (via HDMI-to-DVI cable [1]) . You don't really need the display - once you set up the networking you can connect it to the home router and connect over ssh. Plus by not using the display you'll have more memory available for the OS and applications. Make sure you get the fastest card you can afford, maybe even an industrial SD-card (that has SLC and not MLC, thus better endurance). > Please add to my list of absolute minimum "essentials" & please > let me know if any psu, with the correct specs, of course, will > do...

It needs to be at least 700 mA (http://elinux.org/RPi_Hardware) or you will have strange crashes. I've been using one with 1A power cable and its been solid. A class 10 SD card will give you a quicker boot time and r/w performance. I hear a powered USB Hub is great if you need more than two ports or you keyboard or mouse are drawing too much power. (Probably crash if it's power related as previously.) Not necessary, but I love the cheaper little plastic cases from adafruit. Also love the Wi-Fi USB adapter, but not necessary unless you are doing some Wi-Fi projects.

After getting fed up with puppet, I'm seriously considering moving to Ansible. I've spent a couple hours the last few days poking at it, and it's been a *much* more pleasant experience than I've had with puppet. Second, any post-Minnebar thoughts? The most enjoyable (and useful) session I attended was the monitoring session. Among other projects, this session introduced me to Sensu[2], a new-ish monitoring framework. I've been using Nagios for years, and it holds a dear place in my heart. In my current gig, though, our environment has a very high rate of change. Servers get started and destroyed programmatically, sometimes on a minute-by-minute basis. This makes using legacy monitoring products like Nagios very painful. Sensu uses a subscription-based model where clients register themselves with the server and "subscribe" to different roles. Based on that role's configuration, the server starts checking services on the client. I haven't started playing with Sensu yet, but I will likely be doing so in the next few days, as I don't want to invest any more time in my Nagios setup if I'm going to be deprecating it soon. Anyway, that's all for now - I'm looking forward to hearing from (hopefully) some of you!

Ansible seems to fit the bill in many ways for our project - it's python-based, and we're all python devs, so that works well. Additionally, it operates over "vanilla" ssh, and doesn't require any client-side code other than a python interpreter, which is very nice for keeping things clean and simple. > They also said if you're not using one of these tools you're doing it > wrong :) > If by "one of these", they meant a configuration management system, I'd agree with that. > Let me know if you want I can put you in touch with the guys who were > giving the talk. > Bryan had his contact info on one of his slides, so I'm all set.

Used these for RAID0 drives and forensic processing at a previous job. They either worked or they didn't out of the box, and the failure rate was extremely low. Granted you're paying more for 10k RPM, but if you need performance it's worth it- may not be feasible in your situation. For a large, cheap storage solution at my current gig, we went with a large group of 3 TB WD Blue drives and have been happy. IMO something about the Green Intelligent RPM statement (likely 52ish RPM on these) drives make me a little nervous on the performance end. If you're not worried to max performance, maybe this won't be an issue.

Yes, do-release-upgrade. That's a good one to know. I usually just choose it from the update manager window, but I am using X. So here's a question -- to upgrade to the latest version, must one upgrade to each intermediate version in between? For example, I have a machine with Ubuntu 10.10... $ cat /etc/issue Ubuntu 10.10 \n \l ...(in case anyone forgot how to tell the release version), and if I want to upgrade to 13.04 in a few weeks, do I have to go through 11.04, 11.10, 12.04 and 12.10 first?

That should work without issue especially if you let it remove the packages that are no longer supported at the end but I don't think I'd trust that process if it was a machine I was depending on. For what it's worth I just did some 'do-system-upgrade' upgrades from 12.10 to 13.04 without any issues, but I keep pretty clean systems (no installs from source, etc....) so I rarely have problems.

You can upgrade directly from one LTS to the next LTS (eg. 10.04 to 12.04), but can only go from a non-LTS to the next release. So, from 10.10 to 13.04, your upgrade path would indeed by the full list of 10.10, 11.04, 11.10, 12.04, 12.10, 13.04. If you were on 10.04 instead you could go 10.04, 12.04, 12.10, 13.04. HOWEVER, I *believe* the current versions of the upgrade tools (both CLI and GUI) have been improved to have some kind of multi-step capability, such that doing this becomes slightly less awkward for the user (although still very time-consuming). I don't recall what it actually does, but I seem to remember something changing. This is definitely a time when having a local APT mirror comes in handy. :) - Tony -------------- next part -------------- An HTML attachment was scrubbed...

They have been ignoring our pleas since beta Win 8 to have IE 10 in Win 8 respect global font anti-aliasing (it never has- they say this was intentional for the tablet market and they won't fix it). IMO the market shifts and ebbs and flows, however tablets will not fully replace desktop computing any time in the near future. Canonical is like Microsoft, I'll give you that. The whole we don't give a lot of weight to what our end users want because we think we know the market and what is best for them is definitely at play for both. I think it took a few major media outlets and compiled statistical complaints before MS even considered putting the start menu you back as a registry item. For those stuck with Win 8- I recommend Classic Shell (open source). I'm darn near Win 7 UI with it. All that said, I hope they do put in a registry switch for the classic Start menu. I still use Windows for work and occasionally at home- sometimes there is just no way around that. -- Jeremy MountainJohnson Jeremy.MountainJohnson at gmail.com On Mon, Apr 22, 2013 at 1:06 PM, Jason Hsu wrote: > http://www.forbes.com/sites/davidthier/2013/04/22/microsoft-reportedly-reintroducing-start-button-with-windows-8-1/?partner=yahootix > > It looks like Microsoft will be bringing the Start button back to Windows.

I think any development teaim will ignore a complaint they disagree with. Isn't that the issue? Microsoft is strategic. People say they are losing market share because of dropping the Start button, so they are adding it in the next version. Is Ubuntu losing market share because of Unity? Maybe, but not so much that they will act to fix it.

Raspberry Pi Day will be a whole day (9:00am to 5:00pm) dedicated to working with and learning about the Raspberry Pi ! This will be hands-on, so bring your Raspberry Pi and follow along with your own Raspberry Pi! Here is the agenda so far: 9:00 - 11:30 - Starting with your Pi (by Brian Dolan-Goecke) Step-by-Step to get you started with your Raspberry Pi. What you need to know to get set up, to start loading and working with the basics with your Raspberry Pi. 11:30 - 1:00 - Lunch For Lunch, we will order pizza for all who would like to go in on buying some pizza. ( You are also welcome to bring your own lunch or go somewhere else.) Afternoon sessions: 1:00 - 2:45 Blink'n Lights (by ) Using several things on the breadboard (RGB LED control, temperature and humidity sensing, light sensing, reading a switch), plus it could be added to on the fly as well, if there are any interesting ideas. (It would be useful to have a Adafruit Pi Cobbler Breakout Kit, http://www.adafruit.com/products/914 ) Or 1:00 - 2:45 ???? Hope to add another session ???? 3:00 - 4:45 XBMC on the Raspberry Pi (by Brian Dolan-Goecke) Load and working with XBMC. Or 3:00 - 4:45 GPIO with C How to use C to program and use the GPIO pins on the Raspberry Pi. 4:45 - 5:00 Raspberry Pie! Raspberry Pie, the kind you eat! *** If you plan on going please sign up on the wiki. http://www.penguinsunbound.com/Meetings/20130427_-_Pi_Day *** *** If you or, if you know someone, that has worked with Raspberry Pi and would be willing to present (or help) at the meeting please contact Me (Brian Dolan-Goecke) from http://www.goecke-dolan.com/Brian/sendmeail.php *** Thanks I hope to see you there! ==>brian.

I was playing with 8 bit Atmel-AVR microcontrollers, assembly language, freepascal on linux, and the RS232 port. There was one or two suggestions. Then the Raspberry-Pi showed up about 10 steps more advanced with bells and whistles, using linux. Now I'm playing with crummy timers (when used below 1 msec) and the wonderful XForms windowing library on linux. They (XForms) have a nice stripchart demo, and could be a great display signal-analyzer, but linux on a big motherboard has a timing mind of its own. I'm still looking for cheap, slave, real time terminal proto-boards to control from a $100 p4 linux box. I don't know if the Raspberry Pi can run open-DOS? But maybe I should instead consider hooking a Raspberry-Pi to a wheelchair so I can zone out watching 1960s TV shows and summon help at a nursing home. Lots of fun seeing new people enjoy this great new hobby kit. A real winner.

I also wanted to help but was unsure of what to say. I don't really know what this is about... "I am a noob I was wondering about listening in on command lines and stuff." ...but it sounds intriguing. So a longer message explaining what you're trying to do would probably work for you. I don't know if the question is about snooping on another user's shell, or about the bash history, or something else.

Finding files that have been > modified and sent to folders on a certain date in time. Do you know the date, or the folders? Find does not take an argument specifying the date (such as 4/1/2013), but it takes a 'how long ago' argument expressed in hours or minutes (mtime/mmin). Now, we need to find out how many minutes ago was "4/1/2013 18:05" . For this we use 'date': date -d "4/1/2013 18:05" +%s This invocation returns how many seconds passed between 1/1/1970 and the desired date. To find out how many seconds ago it was, you subtract that date from today's date: echo \( `date +%s` - `date -d "4/1/2013 18:05" +%s` \) \/ 60 | bc When I just ran that command, I got back 35013. Given that 24 days * 24 hours * 60 minutes = 34560, the number seems to be in the ballpark ;) Now, we can plug that number in the call to find: find /path/to/top/directory -mtime -35013 > The 'find' > command is very powerful I believe. I would enjoy a workshop and to > listen and be able to talk with others 'such as yourself'. The best chance would be to go to the Penguins Unbound meetings and ask if somebody can explain or show some commands to you. Second best is to ask questions on the mailing list. Most people are friendly and helpful but to help them help you, please read: http://www.catb.org/esr/faqs/smart-questions.html (Thank you for the aside, but it will be a while until I'm back in Minnesota.) > I am sorry > to not send my message clearly I have no formal education.

So if you haven't got your Raspberry Pi yet, make your way out to MicroCenter NOW and get one! (These kits are $124, but they come with all you will need to get started along with quite a bit of extra stuff, including some of the parts needed for the Blink-n-Light) **** Raspberry Pi's @MicroCenter **** "Raspberry Pi Day" at Penguins Unbound Meeting APRIL 27th 2013! Raspberry Pi Day will be a whole day (9:00am to 5:00pm) dedicated to working with and learning about the Raspberry Pi ! This will be hands-on, so bring your Raspberry Pi and follow along with your own Raspberry Pi! Here is the agenda so far: 9:00 - 11:30 - Starting with your Pi (by Brian Dolan-Goecke) Step-by-Step to get you started with your Raspberry Pi. What you need to know to get set up, to start loading and working with the basics with your Raspberry Pi. 11:30 - 1:00 - Lunch For Lunch, we will order pizza for all who would like to go in on buying some pizza. ( You are also welcome to bring your own lunch or go somewhere else.) Afternoon sessions: 1:00 - 2:45 Blink'n Lights (by ) Using several things on the breadboard (RGB LED control, temperature and humidity sensing, light sensing, reading a switch), plus it could be added to on the fly as well, if there are any interesting ideas. (It would be useful to have a Adafruit Pi Cobbler Breakout Kit, http://www.adafruit.com/products/914 ) Or 1:00 - 2:45 ???? Hope to add another session ???? 3:00 - 4:45 XBMC on the Raspberry Pi (by Brian Dolan-Goecke) Load and working with XBMC. (if there is enough interest I will talk about this.) Or 3:00 - 4:45 GPIO with C How to use C to program and use the GPIO pins on the Raspberry Pi. 4:45 - 5:00 Raspberry Pie! Raspberry Pie, the kind you eat! *** If you plan on going please sign up on the wiki. http://www.penguinsunbound.com/Meetings/20130427_-_Pi_Day *** *** If you or, if you know someone, that has worked with Raspberry Pi and would be willing to present (or help) at the meeting please contact Me (Brian Dolan-Goecke) from http://www.goecke-dolan.com/Brian/sendmeail.php *** Thanks I hope to see you there! ==>brian. Be sure to order and get your Raspberry Pi today! (*** it is probably too late to order one, but I understand MicroCenter has the kits mentioned below ****) You can get a "Maker Shed" kit at MicroCenter http://www.microcenter.com/product/402492/Raspberry_Pi_Starter_Kit (They were out of stock when I check earlier today. Be sure to select the Minnesota store in the drop down list in the middle of the page header at the top.) Here is more info about the "Maker Shed" kit http://www.makershed.com/Raspberry_Pi_Starter_Kit_Includes_Raspberry_Pi_p/msrpik.htm You can order from adafruit (they seem to have them in stock when I checked today) http://adafruit.com/category/105 They also have several additional accessories, and project for the Raspberry Pi. They had several in stock on April 22nd with 3day shipping! Jack Ungerleider mentioned you can get a Raspberry Pi here also http://www.mcmelectronics.com/ I am sure there are many more places on the internet if you look *** If you don't know what the Raspberry Pi is see these links http://en.wikipedia.org/wiki/Raspberry_Pi http://www.raspberrypi.org/ From susan.dawn.stewart at gmail.com Fri Apr 26 20:05:28 2013 From: susan.dawn.stewart at gmail.com (Susan Stewart Davis) Date: Fri, 26 Apr 2013 20:05:28 -0500 Subject: [tclug-list] Raspberry Pi Day Message-ID: We got our RPi today, Adafruit's Starter Kit. My 14yo son had the case assembled in under 10min! Unfortunately, my 13yo daughter is in a STEM program at the SMM's Kitty Andersen Youth Science Center which is requiring parents to attend a meeting from 10AM - 1PM tomorrow. She told me this Thursday evening! Yep! So my son opted to go to Lowertown's Art Crawl & we'll see about attending the RPi workshop in Mpls next month. I may try to stop in towards the end of the day, closer to 2pm. I checked out 3 RPi books from Metro State U which I intended to bring.

In-Reply-To: References: Message-ID: The RPi workshop was totally worthwhile, even tho I only got to go for the last 2.5 hours, so I missed all the presentations. :( I arrived behind the eight-ball @2:30, without even a distro loaded on my SDcard, Brian took care of that for me in short order to get me up & running - thank you! & another guy walked me through the setup. (Ugh - I'm really bad w/names & faces, so please forgive me & please reintroduce yourself to me again at the next meeting!) I got Atari games & Libra office installed on the Raspbian desktop, talked about projects - was told my streaming Netflix gamelan would be a no-go :-( Also shared the library books I brought & ate homemade raspberry pie baked Brian's wife. Mmmmmm! Saturday I also showed my RPi to a very interested Staff Member for the SMM's Kitty Anderson Youth Science Center, while there for a parent's meeting prior to my arrival @TIES. I'll have to get to work on my RPi skills because I volunteered to be a parent volunteer when they add the RPi to their Arduinos in the Student Lab. :-) & let me not to forget to mention, I got a one-on-one demo of the GPIO interface by setting up lights on a breadboard (no soldering required if you purchase Adafruit's Starter Kit.) Again, I'm bad w/names/faces :( So please know I appreciate it everything & forgive me for not shouting out thank yous by name!
