[SOLVED ]makepkg asking for pacman-color binary

After upgrading pacman to 4.1 I'm getting this error every time I run makepkg:
/usr/bin/makepkg -s -i
==> ERROR: Cannot find the pacman-color binary required for dependency operations.
Even if I try to use --nocolor:
/usr/bin/makepkg --nocolor -s -i
==> ERROR: Cannot find the pacman-color binary required for dependency operations.
I've tried enabling and disabling color options in both makepkg.conf and pacman.conf, and the error is still there.
Any clue on what could be going on and how to solve it?
Thank you in advance

echo $PACMAN
pacman-color
I guess I've forgotten to edit some file that I changed when using pacman-color-testing from the AUR.
EDIT: Indeed, I forgot to edit my .zprofile that used to export PACMAN as pacman-color. Solved now
Thank you, Allan

[solved] Perl script for pacman updates in Conky

Hi
I've been using this script in Perl Conky to check on updates. It works well.
It's not mine - I got it here;
http://bbs.archlinux.org/viewtopic.php?id=57291
#!/usr/bin/perl
## script by Xyne
## http://bbs.archlinux.org/viewtopic.php?id=57291
use strict;
use warnings;
my $n = (`pacman -Qu | wc -l`);
chomp ($n);
if ($n == 0)
print "System up to date"
elsif($n == 1)
print "1 new package"
else
print "$n new packages (inc. IgnorePkg) "
I have some packages listed in IgnorePkg in pacman.conf - is there a way to exclude them from the packages counted in $n?
I thought something like this would help but I don't see how to take only part of a line from IgnorePkg
http://www.perlfect.com/articles/perlfile.shtml
Thanks for any help
EDIT I added a --ignore clause to the pacman query. Seems to have worked. Sorry to waste your time.

Speed limit on wrt54gs

Hi all.
I have 2 PCs connected to the net via my wrt54gs router, one through a cabale and the other one wirelessly. Is there any way to set the speed limit for the wirless or both PCs? Like make it 50/50 all the time.
Thanks.
Regards.

If you didn't prioritize any device, the router should already work that way. The wired connection is always going to be faster because it's wired.
The box said windows xp or better... So I installed Linux!

Temporarily Increase Customer credit limit for va01

Hi,
My requirement is we want increase credit limit for customers for 1 or 2 days in temporarily basic or va01 order release purpose .
I maintained customer wise temporary credit & valid from and to dates in a z-table. How to solve this problem without using credit management FD32.
regards,
moon.

Your requirement to increase Credit LImit of Customer for 1 - 2 days based on a Z-Table is not possible in SAP Standard. Also you dont want to use FD32.
Now in OVA8, Under Checks you have three Boxes for User 1, 2, & 3. There are the Enchancement Points give by SAP for you to implement your Z-Requirment in Credit Management.
You Requirement will have to be mapped in a Z-Development, speak to your ABAPer & he can write a code in User Exit which will refer your Z-Table & do the needful.
Hope this helps,
Thanks,

Size limit for how much video can be included in an AIR file?

I'm making an AIR app to play a video locally. It is on a PC with no internet connection, so the video (fv4) is included with the air install file. Is there a size limit for how much video can be included in an AIR file? I seem to get the "...file is damaged..." error when I include a video over 200mb. I use Flash CS4 to create and AIR is v 1.53.

I'm authoring in CS4 on a MAC with the latest OS and 4GB ram. It plays fine on the Mac. On a WIN7 PC with all updates and 4GB ram I get the errors if the air file that contains a video file over 200mb. I heard that AIR 2 should solve the issue and that it is just a PC issue.. Maybe... I have not tried using ADT to package the file.

A browser with download speed limit?

It sounds weird but on Linux I can't find a browser that allows to set a download speed limit.
I found an extension for Firefox but it works only on Windows.
I know the existence of download managers like d4x, wget, jdownloader, etc... but some downloads can only be done by browser.
I know trickle too but if I want to change the speed limit I have to 'restart' the command (interrupting the current download).
Then I didn't find an extension for Chromium.

I was able to implement [global] throttling with wondershaper. You will need to modprobe sch_cbq if you use the CBQ script (not sure about the HTB one). I use the CBQ version.

Is there a size limit for uploading files?

is there a size limit for uploading files?

You have max 20GB storage.
Upload anything you want up to that limit - be it one file or many.
The only limit after that is the speed of your internet connection since extremely large files can take hours to upload.

Speed limit

Hi!
My turn to ask a question. I read some- and everywhere the Athlon XP has a MHz limit of 2500. It seems to be so, but is it? I tried on my own to find an answer, and below is a result of that, but...
Why I don't ask AMD?! Before asking well-paid and intelligent people, I thought I should try the forum.
Speed limit
Athlon XP and Sempron reached a speed limit
The main difference between the socket A processor nowadays seems to be in the architecture of the cache memories. The speed does not pass 2500 MHz. Why is that?
The first Athlons came in 1999. Their advantages compared to their competitor are/were the number of pipelines and calculation units:
- Three decoders for translating the complex but fundamental CISC-instructions into RISC-instructions. The processor has no problem working with the short and simple RISC-instructions.
- Athlon can have 72 instructions simultaneously, (Pentium III 40, and the earlier K6 only 24).
- Very competent FPU:s, three of them, and as FPU is better at calculating decimal numbers than the main ALU, it makes Athlons good at 3D graphics – where there are lots of that kind of mathematics when producing polygons.
In the beginning Athlons had external Level 2 cache. The cache sat on a slot beside the processor, and the architecture was called slot 1. With XP this changed, both Level 1 and Level 2 cache were built into the processor, and we got the socket A kind. Athlon XP was also built with thinner lines connecting the transistors, and got the ability to handle new instructions, got a better data pre-fetch technology, and an overheating protection.
So what’s the problem? Speed it up!
Well, one bottleneck lies between the processor and the RAM memory, the Front Side Bus (FSB). The processor is much faster than the RAM and process data as they come by. To keep the processor busy mainly Intel invented a sort of pipeline, or ladder. The processor is working on every step.
Data is sent from hardware, like sound data or network data over the PCI-bus, graphics data over the AGP-bus, hard-disk data over the IDE (PCI-/SATA) bus, etc. The data comes in ones and zeroes in little packages, which make up complex instructions. For the processor to be able to efficiently perform the instructions they need to be sized down to simpler instructions, from CISC to RISC. (CISC codes is such a fundamental part of the PC history they must remain.) The sizing down is done in the very beginning of each pipeline. In later steps of the pipeline, the instructions are interpreted further and performed.
Early processors needed one clock-cycle per step in the pipeline, but Athlons can manage 2,5 steps, as can for example Pentium 4. With the pipelines, as said, Athlon XP can do 72 instructions at the same time. Pentium 4 however has longer pipelines – with 20 steps – and can process 126 instructions. But the efficiency of a Pentium 4 is lower, which is why Athlons are quicker at the same MHz. Apple’s (Motorola’s) G4 processor is yet more efficient.
Athlon XP has 10 steps in each pipeline for the “main” ALU processor and 15 for the FPU. The reason why there are not more pipelines is that the processor is not kept busy with the slower RAM, and a lot of clock-cycles would be wasted. What is more, there will be too many erroneous instructions, when the processor has to start over, filling the pipelines with correct instructions.
RAM is slower
This was not the case in the beginning. All ran at the same speed, say 20 MHz: Processor, FSB, RAM-memory, PCI-bus etc. By separating the PCI-bus, which had hardware connected that couldn’t work at higher frequencies, things could start moving.
In 1989 came a Pentium with clock doubling. To compensate for the not ‘doubled RAM, L1 cache was invented. But processors kept getting faster. Next thing to be pushed forward was the FSB, which for socket A boards now is increased to 200 MHz x 2 (DDR). Intel increased it even further, but as the efficiency rate isn’t increasing at the same rats, Intel has backed down from the megahertz spiral, and has followed AMD in other ways of thinking.
So is this the simple basic calculation?
Athlon XP:s can do 2,5 instruction per clock-cycle in 10 steps per pipeline x the number of pipelines. The number of pipelines is limited by the number of instructions sent and their quality, 72 instructions at the same time. Can this be the reason for 2500 MHz limit?

Ok, reality check people...
Sharp, nice explanation, but you are wrong.
the x86 instruction set (including those nice MUL, ADD and other instructions) is a CISC instruction set.
The difference? A MUL takes 12 cycles, a DIV 40 or something...
RISC was a new computing architecture. Each instruction is simpler to allow higher execution frequency.
The efficiency of a computer is judge by the work done. W= IPC x Freq
Frequency is the well known number that we can find on our beloved processors. IPC is the instructions per clock. Why is the athlon more efficient than a P4 at the same frequency? higher IPC.
How do the chip manufacturer choose those factors?
Well, the problem is that the instruction set is FIXED. x86 (or i386), the instruction set, has been defined years ago as CISC and to maintain compatibility, you have to keep it. They then included internal decoders to change those instructions to streams of RISC instructions, each simpler. Those are the ones really implemented.
How does that influence the speed of the processor? Each instruction is executed by a unit (integer unit, floating point, MMX...), the more that unit has to do for that imstruction, the more time it takes (and the more transistor). This has 2 problems:
- one is that it will limit the overall speed as the more complex the unit, the less speedy.
- The second is that it ties down the unit. If you do a div in 40+ clocks, your integer unit is tied during this time.
The answer to this problem? Pipelines.
Pipelines are splitting the tasks in simpler tasks and executing each as independant as possible.
Example: laundry. You need washer and dryer. However, some of your clothes cannot go to the dryer.
Now, you have 2 loads. If you have a combined unit that takes 1.5h for wash + dry, it will take 3h total.
If you have a washer (.5h) and a dryer (1h), you load the first load (.5h) then transfer it to the dryer (1h). While the drier works, you load the next washer (0.5h). If you need it to perform also the drier, total time is 2.5h instead of 3h. If you dont need it, it is even faster 1.5h.
This is the way intel followed. Prescott has a 25+ pipeline. The problem comes from branches. If you misspredict your branch, you have to flush the pipe.
All that to say that with its manufacturing and its architecture, AMD could not release a AXP even close to 2.5GHz. Can you overclock a good unit over that limit? Sure. Intel did not release a 4GHz and yet you can overclock some P4 up to 5GHz (with appropriate cooling).
Oh, and the technology used is 90nm or 0.09um. Athlon XP is not even that small, it was still on 130nm.
This is the smallest critical dimention (smallest trace. Usually smallest transistor width).

FTP speed limit

Hi there,
Trying to figure out why my upload speed is so slow using FTP. I'm working on a 10/10 link full duplex and my speed tests are pretty good overall. My question is why my upload speed using FTP with my browser/explorer is around 150Kbps while the same
file on the same host using FileZilla goes aroung 900Kbps ?! While testing, I disable my AV just to be sure.
Did some research and found a buffer/speed limit on ftp command (ftp.exe /?). Could that be the explanation or am I missing something ?
Thank you

Just to clarify, some questions please:
Are you on a network?
By "Upload", you mean uploading a file over the internet, not within a LAN or WAN, right?
When you say the same file goes 900 kbps using FileZilla, you mean upload, not download, correct?
Also, what kind of internet connection do you have?
One possibility, based on what you've mentioned, is that the server you're uploading to has a maximum speed per connection. This is fairly common. Apps like FileZilla typically use multiple connections to increase download speeds; I haven't used
one in awhile but it's possible they can do this for uploads as well. So if the server you're uploading to has a speed limit of 150 kbps per connection, you'll never be able to get higher speeds unless you use a multithreaded client (like FileZilla).

Speed limit pb

Hello fellows!
I was asked to build a program that calculates the Fine when you exceed the speed limit.
When you exceed 120miles/h the fine is 100$ plus 10$ for every additional mile/h.
I wrote a code,but something is wrong with it. When you drive at the legal speed which is less than 120miles/h it still gives a fine of 100$.
import javax.swing.JOptionPane;
public class radar
     public static void main(String args[])
          String si,so="";
          int s,q,f;
          si=JOptionPane.showInputDialog("Enter the speed");
          s=Integer.parseInt(si);
               q=s-120;
          if ( q>0 )
               f=100+10*q;
               so+="The speeding fine is"+" "+f+"$";
               JOptionPane.showMessageDialog(null,so);
          if ( q<=0 )
               so+="You are in the legal speed.There is no fine to pay";
               JOptionPane.showMessageDialog(null,so);
          System.exit(0);
}This is the first time i'm using the (if) condition. So please tell me if there is something wrong with it.

perhaps you forgot to add { } to your if statements, otherwise only the first statement is conditional regardless of your indentation.

Custom dowload manager for pacman in chroot env

Hello
As this is the place for pacman in general I post here. Feel free to move that thread if you feel it would have a more suitable place.
I'm willing to install Arch on my computer from the live disk of another distro (Tails, based on Debian). I follow these guidelines but an issue is risen because of Tor wich makes resolving DNS less straightforward. Thus I've tried to use the option XferCommand in /etc/pacman.conf in the following way:
XferCommand = /usr/bin/curl --socks5-hostname 127.0.0.1:9050 -C - -f %u > %o
but I just get errors.
# pacman -S arch-install-scripts
warning: database file for 'core' does not exist
warning: database file for 'extra' does not exist
warning: database file for 'community' does not exist
error: target not found: arch-install-scripts
# pacman -Syu
warning: database file for 'core' does not exist
warning: database file for 'extra' does not exist

sh: /usr/bin/curl: No such file or directory
error: failed to update community (error invoking external downloader)

Would you have any idea to solve this problem? Of course I've checked that /usr/bin contains curl with this line:
XferCommand = ls /usr/bin && /usr/bin/curl --socks5-hostname 127.0.0.1:9050 -C - -f %u > %o
but it seems to be very contradictory:

Max limit for bulk insert.

Hi friends,
We have 100 Million records in a table on production database. We are planning to move the data to test environment for performance tuning of the databse and queries.
We have created a DB Link between these DB's to transfer the data between the database.
We are planning to move the data in the following fashion:
insert into tab1(.....)
select * from tab1@prod_db_link;
do we have any limit for bulk insert?

> We are planning to move the data to test environment for performance tuning of the databse and
queries.
Flawed premise. What makes you think that the test environment will match the production with a 100% degree of accuracy!? - as that is what you need in order to
a) identify the performance bottlenecks
b) solve these
You are very much mistaken if you think you can identify actual performance issues happening on prod by mucking about on a test environment that just happens to have the same data volume.
Even data volume alone is meaningless as a copy of the data is logical - any potential issues with pctfree and pctused will not be reflected. Any potential hot spots on disk will not be reflected. The copy will not have the same number of segments and extents. Etc. Etc.
And this is just the data.. never mind numerous other issues ranging from actual hardware and operating system to Oracle instance configuration and production load and processing.

Line limit for JTextArea - Urgent

Hi All,
I would like to have 80 character limit for each line displayed in JTextArea. The linewrap along with wordwrap have been enabled for JTextArea but that solves a part of the problem. The no. of characters that can be entered per line depends on the width of the component and the font size. For this component there is no upper limit for the total no. charaters that can be entered. Basically, it supports text editing feature(cut, copy, paste). One way it could have been done by fixing the width of component so that it could accomodate only 80 characters, but again the factors like screen resolution, font's advance width keeps changing. I tried with overriding insertString() of PlainDocument class, but didn't know how to wrap the characters after 80 position to next line if text is inserted in the middle of a line. At the same time the whole text needs a reformatiing. Same behavior is desirable while doing cut/paste operations.
A hint or sample code will be highly appreciated as it has been a long time I am looking to solve this problem.
Thanks
Ritwick.

You are correct it is not easy to override the default behaviour of the JTextArea. So my suggestion is to use a monospaced font. The code would then be:
JTextArea.textArea = new JTextArea( "some text", 10, 80 );
textArea.setFont( new Font("monospaced", Font.PLAIN, 12) );
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
JScrollPane scrollPane = new JScrollPane( textArea );
scrollPane.setVerticalScrollBarPolicy( JScrollPane.VERTICAL_SCROLLBAR_ALWAYS );If using a monospaced font is not possible, then please explain why wrapping at exactly 80 characters is so important, maybe there is a different approach to take.

Ovi Maps 3.04 - Speed limit warner settings

Hi,
Can someone explain how to correctly set the options for the Speed Limit Warner on Ovi Maps 3.04? I'm kind of confused here...
Also, I would like to know how these options differ from the Safety Spot Warner option?
Thanks in advance!

Firstly select imperial or metric, then decide what speed over the limit you wish to activate the warning. Mine is set at 2mph up to 50mph and 3mph over 50mph. In drive mode the speed indicator (bottom left) shows green, but when exceeding 32mph in a 30mph area turns red and emits a warning. Subsequently in a 60mph limit, exceeding 63mph produces a warning. The map software detects the road speed limits, and this is an excellent safety feature. In respect of police safety cameras and mobile speeding units the general concensus is that a tolerance of 10% + 2mph is used to counter inaccurate speedometers. Also note that the speed displayed by the map is by GPS (more accurate than a speedometer). Hope this helps!
