• "Untrusted packages could compromise your system's security." appears while trying to install anything

  - by maria

  Hi I've freshly installed Ubuntu 10.4 on a new computer. I'm trying to install on it application I need (my old computer is broken and I have to send it to the service). I've managed to install texlive and than I can't install anything else. All software I want to have is what I have succesfuly installed on my old computer (with the same version of Ubuntu), so I don't understand, why terminal says (sorry, the terminal talks half English, half Polish, but I hope it's enough): maria@marysia-ubuntu:~$ sudo aptitude install emacs Czytanie list pakietów... Gotowe Budowanie drzewa zaleznosci Odczyt informacji o stanie... Gotowe Reading extended state information Initializing package states... Gotowe The following NEW packages will be installed: emacs emacs23{a} emacs23-bin-common{a} emacs23-common{a} emacsen-common{a} 0 packages upgraded, 5 newly installed, 0 to remove and 0 not upgraded. Need to get 23,9MB of archives. After unpacking 73,8MB will be used. Do you want to continue? [Y/n/?] Y WARNING: untrusted versions of the following packages will be installed! Untrusted packages could compromise your system's security. You should only proceed with the installation if you are certain that this is what you want to do. emacs emacs23-bin-common emacsen-common emacs23-common emacs23 Do you want to ignore this warning and proceed anyway? To continue, enter "Yes"; to abort, enter "No" I was trying to install other editors as well, with the same result. As I decided that I might be sure that I know the package I want to install is secure, finaly I've entered "Yes". The installation ended succesfuly, but editor don't understand any .tex file (.tex files are for sure fine): this is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian) restricted \write18 enabled. entering extended mode (./Szarfi.tex ! Undefined control sequence. l.2 \documentclass {book} ? What's more, I've realised that in Synaptic Manager there is no package which would be marked as supported by Canonical... Any tips? Thanks in advance

• If you had to teach professional development to students that just graduated school, what would be the topics?

  - by user2567

  The idea is to give them more chances to be efficient in a professional environment. Most students are good with theory, most of them are smart, but they have to learn how to solve common technical problems. They will be better programmers as they practice, but maybe we can help them with some introduction training. Which topics you would select for a two weeks full time training? It's an open question, I don't want to suggest things that will reduce the answers to a particular field.

• Attending my first software conference - any tips before I go? [closed]

  - by Paul Weber

  My nice employer allowed me to visit a software conference in June (International PHP Conference, for those who care). Wanting to make the most of it, I would ask the more experienced conference goers in here to give me some tips on what I could do to maximize my learning experience on the conference, and to reduce beginner mistakes. Sorry that this question is a little ambiguous, but I think it's best to keep it a little bit more open, so I can get a wide range of Ideas, and it will be of more use to further people seeking for an answer.

• Which card readers support HID (Human Interface Device) and emulate keyboard input? [closed]

  - by Level1Coder

  I'm looking for a card reader to interface with an inhouse webapp and need it to emulate keyboard input to type the card data (serial number) into a web form. A simple usage scenario would be where I open notepad, have notepad focused as front most, swipe the card, and the card reader can type out the card data into notepad as plain text. As long as this works, the card data can work with any web form. Which card readers supports this kind of keyboard emulation mode?

• How to drag widgets from monitor to monitor in kubuntu?

  - by Mien

  I have Kubuntu 12.04 on my Dell Inspiron. I use an extern monitor as my default one, and my laptop monitor as my second monitor. I can place widgets on the extern (default) screen, but when I drag them to the laptop (second) screen, they disappear. I can put widgets on the second screen, if I open the widget screen on that screen, but I can't drag them to my first monitor. How can I switch between monitors for the widgets?

• Way(s) of browsing the filesystem that are more flexible

  I have two related questions, both probably (but not necessarily preferentially) accepting the same answer : When browsing or exploring the filesystem in a GUI, I want to be able to right click on the empty space between the files, choose a menu item and say 'open terminal in this folder,' optionally as root Do the converse when using the terminal, optionally as root I use Universe with kubuntu but have Debian Lenny running with gnome installed separately, so anything on kde or gnome would work

• Software Architecture Analysis Method (SAAM)

  Software Architecture Analysis Method (SAAM) is a methodology used to determine how specific application quality attributes were achieved and how possible changes in the future will affect quality attributes based on hypothetical cases studies. Common quality attributes that can be utilized by this methodology include modifiability, robustness, portability, and extensibility. Quality Attribute: Application Modifiability The Modifiability quality attribute refers to how easy it changing the system in the future will be. This to me is a very open-ended attribute because a business could decide to transform a Point of Sale (POS) system in to a Lead Tracking system overnight. (Yes, this did actually happen to me) In order for SAAM to be properly applied for checking this attribute specific hypothetical case studies need to be created and review for the modifiability attribute due to the fact that various scenarios would return various results based on the amount of changes. In the case of the POS change out a payment gateway or adding an additional payment would have scored very high in comparison to changing the system over to a lead management system. I personally would evaluate this quality attribute based on the S.O.I.L.D Principles of software design. I have found from my experience the use of S.O.I.L.D in software design allows for the adoption of changes within a system. Quality Attribute: Application Robustness The Robustness quality attribute refers to how an application handles the unexpected. The unexpected can be defined but is not limited to anything not anticipated in the originating design of the system. For example: Bad Data, Limited to no network connectivity, invalid permissions, or any unexpected application exceptions. I would personally evaluate this quality attribute based on how the system handled the exceptions. Robustness Considerations Did the system stop or did it handle the unexpected error? Did the system log the unexpected error for future debugging? What message did the user receive about the error? Quality Attribute: Application Portability The Portability quality attribute refers to the ease of porting an application to run in a new operating system or device. For example, It is much easier to alter an ASP.net website to be accessible by a PC, Mac, IPhone, Android Phone, Mini PC, or Table in comparison to desktop application written in VB.net because a lot more work would be involved to get the desktop app to the point where it would be viable to port the application over to the various environments and devices. I would personally evaluate this quality attribute based on each new environment for which the hypothetical case study identifies. I would pay particular attention to the following items. Portability Considerations Hardware Dependencies Operating System Dependencies Data Source Dependencies Network Dependencies and Availabilities  Quality Attribute: Application Extensibility The Extensibility quality attribute refers to the ease of adding new features to an existing application without impacting existing functionality. I would personally evaluate this quality attribute based on each new environment for the following Extensibility  Considerations Hard coded Variables versus Configurable variables Application Documentation (External Documents and Codebase Documentation.) The use of Solid Design Principles

• Should I continue to pursue programming based on my experience?

  - by El Be

  The reason I ask this question is because I am not sure my troubles come from a lack of confidence, or something much deeper like lack of passion. I'm hoping experienced programmers and developers can help identify the cause of my troubles. To be brief my undergraduate major was in Computer Science, but in a small school and I had the highest gpa in my year in computer science. The first time I ever programmed was once in the 5th grade (using logo) and when I was a freshman in college. I enjoyed programming when I was in school. Then I did an internships where I was expected to produce image processing software and program microchips. I was unsuccessful and produced little results and I hated the job, because I had to figure out everything for myself, did not have any help, and there was a lot of pressure to produce results. Although I tried I could not figure out what to do and was stuck all the time and made me dislike the job. When the internship ended I went to a PhD program for computer science at a prestigious computer science school. I had a very hard time with the course, met people who have been programming since they were 6 and made plenty of applications in their spare time (which I never did, although I tried). I even met many sophomores who understood more than I did. The combination of this and other things have made me feel that programming is not for me, but sometimes I consider a career in programming. I still consider programming as a career because of the career potential (not only just because of money). Based on my experience do you believe my confidence has just been shaken and I should continue to prepare for a programming career, or do you see a lack of passion and it would make it tough to continue programming. thank you for reading and for your advice Thank you for everyone's advice so far! Also: I dropped out of the ph.D program for computer science and switched to a master's in computer graphics. Its more applied, but I still find it hard to be motivated (due to either lack of confidence or passion), but since programming is such a big field I am looking for that niche area that I feel good programming in.

• Gerrit code review, or Github's fork and pull model?

  - by user1366476

  I am starting a software project that will be team AND community developed. I was previously sold on gerrit, but now github's fork and pull request model seem to almost provide more tools, ways to visualize commits, and ease of use. For someone who has at least a little experience with both, what are the pros/cons of each, and which would be better for a team based project which wants to leave open the possibility for community development?

• Scanning the Error Log with PowerShell

  - by AllenMWhite

  One of the most important things you can do as a DBA is to keep tabs on the errors reported in the error log, but there's a lot of information there and sometimes it's hard to find the 'good stuff'. You can open the errorlog file directly in a text editor and search for errors but that gets tedious, and string searches generally return just the lines with the error message numbers, and in the error log the real information you want is in the line after that. PowerShell 2.0 introduced a new cmdlet...(read more)
