Mother of all xterms?

Hey, all -- I've gotten quite used to gnome-terminal and konsole, and 
they both work, but I admit I have a little bit of iterm2 (for the Mac) 
envy -- e.g., being able to search back through the log to a specific 
timestamp.  Handy, that.  So, my question, really, is "is there a really 
cool terminal program out there with lots of bells and whistles?"  It'd 
be fun to kick the tires on something new.

Thanks,

-Ken

How can I detect whether an /etc/rc.d/init.d script is being run at boot time versus by hand?

I'm trying to figure out whether to force the removal of an almost certainly stale pid file or not in the service start case.

While I presume that the start up sequence normally handles this by clearing /var/run before lighting off the init scripts for the level, I have a need to have my pid file in an unusual place (needs to be written and deleted by a non-root process).

I'd like start at boot to be automatic, and if shutdown was clean, it will be.  But if the system crashes (or someone hits the reset button, etc.) there will be a stale pid file come boot time.

I'd like to automatically delete any stale pid file at boot time, but start later should fail claiming that there's an existing process.

So, can I count on parent pid, or maybe process group id, to identify the at boot time case?  Or would that be unwise?

Bill

Re: gps recommendations?

One feature that I was not able to get working on the Android version of 
Google Maps is route manipulation by moving the lines like you can on 
the web version. The advantages of a commercial GPS system, like TomTom 
is the screen size. Also, your maps are all preloaded. In a smartphone, 
your maps are loaded via your data connection, but there is a way to 
preload your maps before going into an area where you may not have wifi. 
It depends on your cache size. Also look at mapdroyd. I once compared 
Google Maps nav with Lexus nav, and I preferred the Google Maps route.

gps recommendations?

My GPS is dying. I'm looking for a replacement, but I want a
particular..."mindset" is probably a better word than "feature".

On a recent long-distance car trip, I found the GPS making opaque
decisions. For instance, it has a route. I take an unplanned exit for
gas and when I get back on, and the GPS has "recalculating"'d several
times, the route is different. Why? I'm exactly where I was before and
the destination is the same. No clue and no way to find out. 

Similarly, I often find that "fastest" and "shortest" are not the only
optimization strategies I could wish for. How about "any route using/not
using road X" or "no tolls, except for this one because it saves 4
hours"? Or "no 'highways' but also don't take me down all these back
country, one-lane roads".

Basically, I find that when I use the GPS, it's the brains and I'm just
the car operator. I want to be the brains and the operator and have the
GPS be navigator. I decide a route (or the backbone of one) and it keeps
me on it.

Does this exist? I know "waypoints" is a thing, but I'm not talking
about visiting landmarks. I'm talking about entering in (most of) my
route and having the GPS handle the details.

Letter from a Microsoft pusher


I received a letter today from a computer recycler which proudly puts 
Windows on their machines and then gives them to people who can't 
afford to buy Windows. Their words are quoted (since I don't know how 
to highlight in ascii):

"Microsoft donates Windows licenses to organizations such as ours, 
millions each year."

Yes, I'm sure they do. The better to get their malware into the hands 
of the unaware.

"When you are poor and want to get a job employers want people that 
know Word, Excel, PowerPoint, Outlook, Visio, Project, SharePoint, 
Dynamics and hundreds of other standard business programs offered by 
Microsoft."

Translating skills from one Office suite to another, such as 
OpenOffice to Microsoft Office, is not different from translating 
between different versions of Microsoft office. However, on the rest 
of these applications, I agree. Somehow, I doubt that they're getting 
free licenses for all of them. The same objection to the expensive 
upgrade treadmill exists for these applications as well.

"We tried to offer Linux systems with open office for $25 a system 
when we started, never had one person ever look at one - we can't 
even give them away - I tried to."

No, they tried to sell them, not give them away.

Even allowing that they dropped the $25 pricetag, it's a fact that 
people think that Windows is Free. The comparison in their minds is 
not the $200 Windows license vs. $0 for Linux/LibreOffice, it's 
between $0 with the Microsoft label and $0 without it. The choice is 
obvious. I have written about this before:

http://anarchic-order.blogspot.com/2011/03/windows-is-not-free.html

And it is the "poor" who are least able to afford not getting 
hacked/cracked upgrades "from a friend" when their "free" Windows 
runs out.

"They want Windows or Apple and Apple has no interest in poor people. 
If you have kids they want to play games - not Linux games, good 
games that their friends are playing online."

Three gross assumptions here:

1) Microsoft cares about people who cannot afford their software
2) Linux games are not good
3) Online games don't run on Linux

2 and 3 are sadly somewhat true, yet rapidly declining. I have to 
wonder what these "poor" people are doing paying for first-run games 
and online game time. Maybe they're getting hacked/cracked versions 
of them?

1, however, is absurd. Microsoft Corporation wants people to buy their 
product. By giving this one away just like the drug dealer, they 
perpetuate the illusion that there is nothing else.

"I think there are lots of zealots running around that think they have 
the only solution for mankind when in fact there are many."

Zealots also push Microsoft crapware.

"You seem to have twisted 'the value of genuine' - all that means is 
LEGAL not cracked or virus ridden."

This copy is all nice and legal, sure. What about the upgrade that 
the "poor" will soon have to buy? Will that also be all legal and not 
cracked or virus ridden? No. Only the first one is free.

Giving people Windows and Microsoft crapware is not doing them any 
favors.

Boston Linux Meeting Wednesday, May 15, 2013 - BeagleBone Black and Open Source Computing

When:May 15, 2013 7PM (6:30PM for Q&A)
Topic: BeagleBone Black and Open Source Computing
Moderators:
Kurt Keville, Thaumaturgical Engineer, MIT Institute for Soldier 
Nanotechnologies - kkeville alum mit edu

Brian DeLacey, www.LinuxInTheLivingRoom.com, b delacey / gmail com

Location: MIT Building E51, Room 315

Summary:

A look at Texas Instrument's newest low-cost ARM platform

Abstract:

The BeagleBone Black was introduced on April 23rd at the DESIGN West 
conference. This next generation, credit-card-sized, open-everything 
microcomputer sells for $45 and offers broad, capable support for Linux 
Distributions and Android. This is a defining moment for Open Source 
Computing.

The May 15th meeting will take a hands-on, hacker-friendly look at the 
new BeagleBone Black. We'll step through board-level operations from 
boot-up to shutdown, from launching Linux to blinking LEDs. Chip by 
chip, Texas Instruments is ushering in a new generation for Open Source 
Computing.

Is BeagleBone Black a capable desktop or energy efficient server? Will 
you run ngstrm, Ubuntu, Android or something else? Will it be used in 
educational, personal, or commercial settings? We'll tour through 
software and hardware ideas for Infotainment, Thing-ware, and Maker 
applications.

Join Brian and Kurt (some call them the caped crusaders of the embedded 
world) as they look back on industry developments since BLU's PandaBoard 
meeting of 2010 and lock in on the promising potential for the brand new 
BeagleBone Black.

Nashua MerriLUG meeting today <at> 7pm

Join us today for MerriLUG in Nashua!

This month's topic: juju http://juju.ubuntu.com

Who: 
Peter

When:
Today at 7pm

Where:
Makeit Labs
29 Crown Street,

Makeit Labs is actually located on the backside of the building at 29 Crown St. and can be a bit tricky to find. To get there, you will need to pass the place the GPS says they are at by at least 200 yards. Take a right onto the tree lined dirt road after Greenerd Press. The dirt road turns right to the train yard and Makeit Labs parking lot.

Failed ubuntu do-release-upgrade work around?

I'm trying, without much success, to dist-upgrade a machine from 10.04LTS to 12.04.2LTS.  The installer seems to timeout because the host (or my network) is not responding.  What is puzzling, is that I can wget the file from the repository.  The download seems to take > 3 minutes to start, (no wget activity) but then the connection is good for a while, stalls, but eventually picks up and completes.  When the connection is active, I seem to have reasonable BW, otherwise I have 8B/sec or 0B/sec download.  It is probably our network $WORK, but I have yet to have anyone be able to help me.

Since I have the file in question, where can I stuff this file, so that the installer sees it, and doesn't have to go to the slow repo to get it again.  I think the dist-upgrade saves stuff in /var/log/dist-upgrade

In main.log the last entries are:

2013-05-03 10:31:40,603 ERROR IOError in cache.commit(): 'Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/t/texlive-extra/texlive-fonts-extra_2009-10ubuntu1_all.deb Connection failed
'. Retrying (currentTry: 2)
2013-05-03 10:31:40,603 ERROR giving up on fetching after maximum retries

Does anyone know where the files are saved for a dist-upgrade that hasn't finished?
