  • Plot smooth line with PyPlot

    - by Paul
    I've got the following simple script that plots a graph: import matplotlib.pyplot as plt import numpy as np T = np.array([6, 7, 8, 9, 10, 11, 12]) power = np.array([1.53E+03, 5.92E+02, 2.04E+02, 7.24E+01, 2.72E+01, 1.10E+01, 4.70E+00]) plt.plot(T,power) plt.show() As it is now, the line goes straight from point to point which looks ok, but could be better in my opinion. What I want is to smooth the line between the points. In Gnuplot I would have plotted with smooth cplines. Is there an easy way to do this in PyPlot? I've found some tutorials, but they all seem rather complex.

  • using egrep to find missing @ in log

    - by jols
    I am using the following command to find log entries that are the result of a log in to the email server: egrep '_login[^ ]' /var/log/exim_mainlog That works fine to find entries that contain content like this: P=esmtpa A=courier_login:[email protected] S=1573 id=f1cd08396,... But what I need to do is to change my grep statement, so that it finds single word logins that do not use the @ sign, like so: P=esmtpa A=courier_login:name S=1573 id=f1cd08396,... Where the log in before was "[email protected]", but in the second log entry, the log in used was only "name". Is this possible using grep or egrep, perhaps in some kind of a compound statement? Thanks much.

  • Got a contract to hire offer

    - by user23838
    I just got a contract to hire position with a local company. They are paying 28/hour. I just graduated from college. They said they will take me in full-time after 6 months. Should I ask for more money? I wanted somewhere between 60-70k. But this offer has no benefits, no paid holidays. They said they hired couple of entry level people for the same amount of money. So, they want to keep the rate the same. Should I negotiate with the recruiter harder? Thanks

  • EVOLUTION: No such Calendar

    - by Dennis
    I am using a google calendar with evolution for quite a while now. I was never having any troubles. Just recently, I suppose just after an update, whenever I want to create a new event in evolution (for the just mentioned google calendar) I get the err message "No such calendar". When I dismiss changes an re-open evolution the entry has been added anyway. This is somewhat annoying. I googled, but haven't found anything yet which suggests that it not problem many people have!? Looking for help, maybe someone here knows an answer! I appreciate any suggestion! Cheers, Dennis

  • Using TortoiseHg to push to an authenticated git repository

    - by Nathan Palmer
    I'm trying to push a changeset from a local Mercurial repository created with TortoiseHg to a remote Git repository. I have hg-git installed and configured and it will pull just fine. But when I run the push it gives me this Command hg push git+ssh://git@dummyrepo:username/repo.git Result pushing to git+ssh://git@dummyrepo:username/repo.git importing Hg objects into Git creating and sending data abort: the remote end hung up unexpectedly There are several things I've done to get to this point. But I'm hoping to resolve this last thing because I find TortoiseHg to be much easier to work with than any of the Git tools out there (for windows.) Installed TortoiseHg Pulled down the hg-git from http://bitbucket.org/durin42/hg-git/ Configured mercurial.ini to point to the hg-git library Pulled down dulwich source from git://git.samba.org/jelmer/dulwich.git Compiled dulwich and put it into library.zip for TortoiseHg Configured TortoiseHg to use TortoisePlink.exe for ssh Added my private key to Pageant Any ideas what I could be missing?

  • BDE, Delphi, ODBC, SQL Native Client & Dead lock

    - by EspenS
    Hi. We have some Delphi code that uses the BDE to Access SQL Server 2008 through the SQL Server Native Client ODBC driver (2005 version). Our issue is that we're experiencing some deadlock issues in a loop doing inserts to multiple tables. The whole loop is done within a [TDatabase].StartTransaction. Looking at the SQL Server Profiler we clearly see that at one point during the loop the SPID (Session ID?) change, and then we naturally end up with a deadlock. (Both SPID doing inserts to the same table) It seems like the BDE at some point does a second connection to the DB... (Although I would love to skip the BDE, it's currently not possible. ) Anyone with experiences to share?

  • Jupiter seems to break multimonitor setup

    - by Philippe
    If Jupiter is in the startup my multimonitor setup will fail. Instead of two separate desktops the monitors will be mirrored, one over the other with the smaller notebook-desktop in the larger screen: After each new log-in I have to reset the Display settings in the "System Settings..." dialogue to two not mirrored screens, the changes don't seem to be saved. Given the the entry from xsession-errors /usr/lib/jupiter/scripts/resolutions: line 42: /var/jupiter/available_resolutions_LVDS: Permission denied I assumed that it's coming from Jupiter. Infact, if Jupiter is removed as startup application the desktop settings are fine. Any idea how to solve that issue?

  • Problems creating a debdiff

    - by Chris Wilson
    I'm following this guide to create a debdiff for a package I'm patching. Everything goes fine until step number 8 and I attempt to create the debdiff after committing the changes. The package in question is Zim, pulled form Launchpad using bzr branch lp:zim and according to this guide I should execute the following command to create the debdiff: debdiff zim_0.49.dsc zim_0.49ubuntu1.dsc > zim_0.49ubuntu1.debdiff however, when I actually try to execute this command, I get the following error: debdiff: fatal error at line 314: Can't read file: zim_0.49.dsc Upon inspection of the directory in which the files created from debuild -S (step 6) are deposited, I find zim_0.49ubuntu1_source.changes zim_0.49ubuntu1.dsc zim_0.49ubuntu1.tar.gz zim_0.49ubuntu1_source.build but no sign of zim_0.49.dsc. I could probably create one by debuilding the package as soon as I check out the code, before starting work, but that would add an extraneous entry in the changelog. Is there a step missing from the guide that creates zim_0.49.dsc or is the file itself missing from the source?

  • Is there such a thing as too much experience?

    - by sunpech
    For modern software developers in today's world, is there such a thing as having too much experience with a certain technology or programming language? To a recruiter, interviewer, or company hiring-- could there often be cases where a particular candidate has so much experience in a certain area or technology where it works against the candidate to being hired? I'm not talking about cases where a senior developer is applying for an entry-level developer position, and has a lot of experience in that sense. Nor am I talking about cases where a candidate is outright lying (e.g. 20+ years experience with Ruby on Rails). I've overheard this in conversations between hiring managers/developers during happy hours, yet I'm not quite sure I fully understand what they mean.

  • Using a "local" S3 emulation layer as a replacement for HDFS?

    - by user183394
    I have been testing out the most recent Cloudera CDH4 hadoop-conf-pseudo (i.e. MRv2 or YARN) on a notebook, which has 4 cores, 8GB RAM, an Intel X25MG2 SSD, and runs a S3 emulation layer my colleagues and I wrote in C++. The OS is Ubuntu 12.04LTS 64bit. So far so good. Looking at Setting up hadoop to use S3 as a replacement for HDFS, I would like to do it on my notebook. Nevertheless, I can't find where I can change the jets3t.properties for setting the end point to localhost. I downloaded the hadoop-2.0.1-alpha.tar.gz and searched the source without finding out a clue. There is a similar Q on SO Using s3 as fs.default.name or HDFS?, but I want to use our own lightweight and fast S3 emulation layer, instead of AWS S3, for our experiments. I would appreciate a hint as to how I can change the end point to a different hostname. Regards, --Zack

  • Where does the URL parameter "?chocaid=397" come from?

    - by unor
    In Google Webmaster Tools, I noticed that my front page was indexed two times: example.com/ example.com/?chocaid=397 I know that I could fix this with the use of link type canonical, but I wonder: Where does this parameter come from? There are various sites that have pages indexed with this very parameter/value: https://duckduckgo.com/?q=chocaid%3D397. I looked for similarities between these sites. but couldn't find a conclusive one: It's often the front page, but not in every case. Some are NSFW, but not all. When one domains' URL has this parameter, often other subdomains of the same domain have it, too. Examples Wikipedia entry Microsoft Codeplex

  • Storing website hierarchy in Sql Server 2008

    - by Mika Kolari
    I want to store website page hierarchy in a table. What I would like to achieve is efficiently 1) resolve (last valid) item by path (e.g. "/blogs/programming/tags/asp.net,sql-server", "/blogs/programming/hello-world" ) 2) get ancestor items for breadcrump 3) edit an item without updating the whole tree of children, grand children etc. Because of the 3rd point I thought the table could be like ITEM id type slug title parentId 1 area blogs Blogs 2 blog programming Programming blog 1 3 tagsearch tags 2 4 post hello-world Hello World! 2 Could I use Sql Server's hierarchyid type somehow (especially point 1, "/blogs/programming/tags" is the last valid item)? Tree depth would usually be around 3-4. What would be the best way to achieve all this?

  • UIAlertView crashing on undocumented method

    - by morticae
    Our app has been crashing with a frequency of roughly 1 in 1,500 launches due to a bug that is proving elusive. The relevant portion of the stack trace is included. It's being fired as a callback so I have no reference for where it's occurring in my own code. It looks like what's going on is there is a UIViewAnimationState object that is calling UIAlertView's private method (_popoutAnimationDidStop:finished:). Only problem is, it appears the UIAlertView has been dealloced by this point. I don't do anything weird with alert views. I throw them up, and I wait for user input. They are all shown before being released. Anyone encountered this? At this point, I'm leaning toward it being an Apple bug. Thread 0 Crashed: 0 libobjc.A.dylib 0x3138cec0 objc_msgSend + 24 1 UIKit 0x326258c4 -[UIAlertView(Private) _popoutAnimationDidStop:finished:] 2 UIKit 0x324fad70 -[UIViewAnimationState sendDelegateAnimationDidStop:finished:] 3 UIKit 0x324fac08 -[UIViewAnimationState animationDidStop:finished:] 4 QuartzCore 0x311db05c run_animation_cal lbacks

  • Adding AllowPartiallyTrustedCallersAttribute To Paypal ASP.NET SDK

    - by snwr
    Currently, I cannot use Paypal Pro on my host (GoDaddy) because it requires Full trust level. After digging in Google, it seems a workaround is possible by adding AllowPartiallyTrustedCallersAttribute to the Paypal assembly. I have seen code samples that use AllowPartiallyTrustedCallersAttribute in their AssemblyInfo.cs file, however, I've yet to run into a code example that also happens to be using PayPal. My question is where should the AllowPartiallyTrustedCallersAttribute be added in my project if my objective is to make the PayPal assembly work? I have tried adding it to my AssemblyInfo.cs for the project that contains the entire website, but I have not been successful. At this point, any insight or shot in the dark would be greatly appreciated. Even if someone could point me in the general direction of some documentation I would be grateful.

  • Gradient a Parallelogram

    - by nuclearpenguin
    I'm working in JavaScript drawing on a canvas, and have four coordinates to draw a parallelogram, called A, B, C, and D starting from the top-left, top-right, bottom-left, and bottom right, respectively. An example of some coordinates might be: A: (3, 3) B: (4, 3) C: (1, 0) D: (2, 0) I can draw the parallelogram just fine, but I would like to fill it in with a gradient. I want the gradient to fill in from left to right, but matching the angle of the shape. The library I use (CAKE) requires a start and stop coordinate for the gradient. My stop and start would be somewhere half way between A and C, and end somewhere half way between B and D. Of course, it is not simply EXACTLY half way because the angles at A, B, C, and D are not right angles. So given this information (the coordinates), how to I find the point on the line A - C to start, and the point on the line B - D to stop? Remember, I'm doing this in JavaScript, so I have some good Math tools at my disposal for calculation.

  • How to fill certain application design learning "gaps"?

    - by e4rthdog
    In life it doesnt matter if you do one thing for 15 years. You will end up waking one day and asking stuff that are equal to "how do i walk?" :) My specific question is that as a new entrant to C# and OOP i am stepping into many little "details" that need to be addressed. Written a lot of code in VB.NET / cobol / simple php e.t.c surely does not help much into the OOP world... So , even after reading entry level books for C# and watching some videos i recently found out about the "factory model design" for applications. I would appreciate if any of you guys recomment some reading on application design architecture for further reading...

  • Caching of toolbar names in ArcMap

    - by Marko Apfel
    For little GUI-changes in own ArcMap-customizations normally it is enough to start the application and look that every entry is visible. Especially for refactoring of an own toolbar it was still enough to verify that the toolbar is already shown in the choice-list. But this is a fallacy: the entries there comes from a cache. You could verify this by dumping informations in the toolbar constructor. The constructor is only called if the toolbar is activated! Otherwise you see the toolbar name, but this name comes out of a cache. The cache is stored in the registry under: HKCU\Software\ESRI\ArcMap\Settings\CommandBarNameCache

  • Google maps nearest points avoiding rivers / by itinerary

    - by Karl Lacroix
    Here is the deal : I need to find the closest points from a point with a radius. For example, I need to get all the points in a 15 km radius. Thats easy with Google Maps Radius and all the examples on the web ;) The problem is that from my office, a point is under the 15km radius, but it's on the other side of a river, so the car itinerary is about 30 km (using a bridge)! Is there a simple solution to exclude those points or to calculate by intineraries ? I supposed that I'll need to calculate all itineraries with returned points? DirectionsRequest API? Thanks! :)

  • Creating an installer with WPF forms, packaged files and custom setup actions in C#

    - by RodH257
    I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

  • History of open source software

    - by Victor Sorokin
    I've been always interested, out of the pure self-amusement, in the history of open software used today: who were the people which started it and what were the reasons to start what were design decisions at the start how software evolved over the time Specifically, I'm interested in following software: GCC X Linux kernel Java Of course, there is plenty of information in Internet to google for, but I thought it would be nice to have list of interesting resources at this site. I hope some of visitors of this site have similar interest and can share a link or two they found particularly amusing/interesting. To make this entry more question-like, here's straight question: what are the most interesting/amusing links about history of open source software?
