• PackageForTheWeb "should not be executed directly"

  - by Sergei Ousynin

  When trying to install package (specifically, chipset drivers for Nexcom PEAK-series computer, but I guess it doesn't really matters) I get "PackageForTheWeb Error" saing "This program is used internally by PackageFromTheWeb. It should not be executed directly." I get this error on both Windows 2000 (where it should be installed) and Windows 7. The original driver CD was lost long time ago, so the package was downloaded from the Nexcom website, found no info about installer prerequisites there. What should I install (or anything else) to install this package? UPD: I found a solution - unpacked the package and executed setup.exe that was inside. But I'm pretty sure it's not an action supposed by vendor, so answers are still welcome.

• Password not working for sudo ("Authentication failure")

  - by Souta

  Before I mention anything further, DO NOT give me a response saying that terminal won't show password input. I'm AWARE of that. I'm typing my user password in (not a capslock issue), and for some reason it still says 'Authentication Failure'. Is there some other password (one I'm not aware of) I'm supposed to be using other than my user password? I've had this ubuntu before, on another hard drive and I didn't have this problem. (And it was the same ubuntu, ubuntu 12.04 LTS) ai@AiNekoYokai:~$ groups ai adm cdrom sudo dip plugdev lpadmin sambashare ai@AiNekoYokai:~$ lsb_release -rd Description: Ubuntu 12.04 LTS Release: 12.04 ai@AiNekoYokai:~$ pkexec cat /etc/sudoers # # This file MUST be edited with the 'visudo' command as root. # # Please consider adding local content in /etc/sudoers.d/ instead of # directly modifying this file. # # See the man page for details on how to write a sudoers file. # Defaults env_reset Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification root ALL=(ALL:ALL) ALL # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL # See sudoers(5) for more information on "#include" directives: #includedir /etc/sudoers.d I can log in with my password, but it's not accepted as valid for authentication <-- That is pretty much my issue. (Although, I haven't gone into recovery mode.) I've ran: ai@AiNekoYokai:~$ ls /etc/sudoers.d README And also reinstalled sudo with: pkexec apt-get update pkexec apt-get --purge --reinstall install sudo pkexec usermod -a -G admin $USER <- Says admin does not exist su $USER <- worked for me, however, my password still does not do much (in sense of not working for other things) I changed my password with pkexec passwd $USER. I was able to change it no problem. gksudo xclock was something I was able to get into, no problem. (Clock showed) ai@AiNekoYokai:~$ gksudo xclock

• Calculation of Milestones/Task list

  - by sugar

  My project manager assigned me a task to estimate the development time for an iPad application. Lets assume that I gave estimation of 15 working days. He thought that the number of days where too many and client needed the changes to the application urgently (as in most of cases). So, he told me: "I am going to assign two developer including you and as per my understandings and experience it won't take more than seven working days." Clarifications I was given the task of estimating development time for an individual. How could I be sure that 2 developers are going to finish it within 7 days? (I am new to team & I hardly know the others abilities) Questions Why do most of project managers / team leaders have understandings like: If one developer requires N days, Then two developers would require N/2 days, Do they think something like developer = s/w production machines? Should a team member (developer, not team lead or any higher post) estimate other developers work? I didn't deny anything in the meeting and didn't said, but what should be the appropriate answer to convince them that N/2 formula that they follow is not correct?

• Second Monitor "Input Not Supported"

  - by Drew

  I have two identical monitors (new Acer s211hl) with a native resolution of 1920x1080. When enabling dual monitor support in Windows 7, the primary monitor works as expected, but the second monitor says, "Input not Supported" and fails to display anything. If I change the resolution of the second monitor to 1440x900, it works as expected. Likewise, if I set it to 1920x1080 with a refresh rate of 30hz, the monitor displays video. However, neither of these are solutions, because the output looks very blurry, and the content is stretched. I am using the following hardware: Monitors: Acer s211hl Motherboard: Asus F1A75M-Pro CPU/GPU: AMD A8-3850 with integrated Radeon HD 6550D graphics I suspect that there is probably an issue with the integrated graphics or motherboard not being able to output to two 1920x1080 monitors, but I am hoping for official confirmation.

• Fullscreen Photo/Video Slideshow App?

  - by Michael Stum

  I have a folder that contains a lot of subfolders which include photos and/or videos. Is there any free application that would display them in a random slideshow? It's something I want to run on a PC mounted on a wall. I point it to that folder and it starts displaying it, with some random/nice transitions. No need for anything more fancy, except maybe Previous/Next controls. Edit: Just a quick clarification. Those pictures change all the time, and there are many of them. It's supposed to be in a store to display product pictures, so it's not like someone is actively watching the whole show. Currently, there are around 150,000 pictures or videos.

• Did C++11 address concerns passing std lib objects between dynamic/shared library boundaries? (ie dlls and so)?

  - by Doug T.

  One of my major complaints about C++ is how hard in practice it is to pass std library objects outside of dynamic library (ie dll/so) boundaries. The std library is often header-only. Which is great for doing some awesome optimizations. However, for dll's, they are often built with different compiler settings that may impact the internal structure/code of a std library containers. For example, in MSVC one dll may build with iterator debugging on while another builds with it off. These two dlls may run into issues passing std containers around. If I expose std::string in my interface, I can't guarantee the code the client is using for std::string is an exact match of my library's std::string. This leads to hard to debug problems, headaches, etc. You either rigidly control the compiler settings in your organization to prevent these issues or you use a simpler C interface that won't have these problems. Or specify to your clients the expected compiler settings they should use (which sucks if another library specifies other compiler settings). My question is whether or not C++11 tried to do anything to solve these issues?

• How can I define custom keyboard mappings to resize, move, and manage windows?

  - by fumon

  I just returned to ubuntu (13.04) after a year using OS X exclusively. I love the improvements that have come to ubuntu and unity, and I'm glad to be back. There's just one thing, though... Slate is a simple OS X tool that allows users to quickly create powerful keyboard macros and really take advantage of their screen space. I have to say I was spoiled by it. Even on a tiny laptop, my workflow was never interrupted by changing workspaces or leaving the keyboard to adjust a window, because perfect adjustment was a keystroke or two away. For example: bind h:ctrl;alt;cmd resize -10% +0 # this increases the window's left width by 10% bind h:shift;alt nudge -10% +0 # this moves the window left by 10% You make a big config file, and like vim, tmux, and everything else, it just becomes muscle memory. I can't seem to find a way to achieve anything close to this in linux or ubuntu. I've tried to make do with compiz window settings and the built-in stuff Ubuntu offers, but it's not even in the same realm. Although to be fair, this level of tuning isn't something most people care about. Thanks, guys. :) Any feedback would be appreciated.

• How can I connect to some old Sun servers?

  - by hellsgate

  We have some old Sun servers (V125, V210, V240, T2000 amongst others) sitting unused and I've been asked to find out if there is anything useful on them before they get wiped and disposed of. However, I've been unable to connect to any of the servers. I tried connecting the servers to a router using the Net Management, Serial Management and standard Ethernet ports. When doing this, I ran 'nmap -sP' from my Linux desktop before and after connecting a server so I could compare the two outputs and hopefully work out what IP address had been assigned to the server, but it didn't appear to have received one. Unfortunately only one of the servers has a VGA output. I was able to access this machine as we still have the login details stored in KeePass, but I've no idea at the moment on how I should go about connecting to any of the others. Any suggestions?

• Google calendar sync has stopped working

  - by Andrew Heath

  I set up Google Calendar to sync with Lightning in Thunderbird. It has worked well for the last few weeks. It has now suddenly stopped working. I have checked the CalDAV addresses and they are all still ok. I do not know if my recent addition of syncing my new Android phone with the Google Calendar has anything to do with it, or just a coincidence. When Thunderbird tries to sync, it asks for the username and password. I enter these for the Google Calendar, and end up in a continuous circle.

• Is it possible to kill a RAS connection which won't disconnect.

  - by sgmoore

  I have a Windows 2003 Server which has a number or RAS Connections to some of our customers. Occasionally the connections go into a mode where there are connected, but not working. Disconnecting and reconnecting solves the problem. However sometimes you can not disconnect as I get the following error message It is not possible to disconnect at this time. The connection is currently busy with a connect or disconnect operation. There are no visible connection dialog boxes when this message occurs and I usually end up having to restart the server which obviously affects all the other users. I know that if you have a service that is stuck 'stopping' you can just kill it. Is there anything similar that you can do to reset a ras connection?

• How much information can you mine out of a name?

  - by Finglas Fjorn

  While not directly related to programming, I figured that the programmers on here would be just as curious as I was about this question. Feel free to close the question if it does not meet with the guidelines. A name: first, possibly a middle, and surname. I'm curious about how much information you can mine out of a name, using publicly available datasets. I know that you can get the following with anywhere between a low-high probability (depending on the input) using US census data: 1) Gender. 2) Race. Facebook for instance, used exactly that to find out, with a decent level of accuracy, the racial distribution of users of their site (https://www.facebook.com/note.php?note_id=205925658858). What else can be mined? I'm not looking for anything specific, this is a very open-ended question to assuage my curiousity. My examples are US specific, so we'll assume that the name is the name of someone located in the US; but, if someone knows of publicly available datasets for other countries, I'm more than open to them too. I hope this is an interesting question!

• "Countersigning" a CA with openssl

  - by Tom O'Connor

  I'm pretty used to creating the PKI used for x509 authentication for whatever reason, SSL Client Verification being the main reason for doing it. I've just started to dabble with OpenVPN (Which I suppose is doing the same things as Apache would do with the Certificate Authority (CA) certificate) We've got a whole bunch of subdomains, and applicances which currently all present their own self-signed certificates. We're tired of having to accept exceptions in Chrome, and we think it must look pretty rough for our clients having our address bar come up red. For that, I'm comfortable to buy a SSL Wildcard CN=*.mycompany.com. That's no problem. What I don't seem to be able to find out is: Can we have our Internal CA root signed as a child of our wildcard certificate, so that installing that cert into guest devices/browsers/whatever doesn't present anything about an untrusted root? Also, on a bit of a side point, why does the addition of a wildcard double the cost of certificate purchase?

• Should I buy this particular MacMini?

  - by sil3nt

  Hello there, I'm not certain if this is the forum I should post this in but here goes anyway. So, I'm honestly clueless when it comes to mac's and I've never owned one before, in fact I still don't own anything with "i" in front of it (not a pc fan, but just low on cash you see:) and I was wondering if these specs are adequate? it's a MacMini G4 1.42Ghz, 1GB ram, 80Gb HDD, 32mb gfx The reason I'm looking for a mac is to start out in some iphone development, and I want a system that wont hang. would this particular system be suitable?. I just need it to be usable and not lag.

• Can't change read only folder in windows 7

  - by James Drinkard

  I'm trying to run a Spring MVC 2.5 tutorial and when I run the ant script for a deploy, I get this error: deploy: [copy] Copying 2 files to C:\apache-tomcat-7.0.8\webapps\c:\projects\workspace\springapp BUILD FAILED C:\projects\workspace\springapp\build.xml:46: Failed to copy C:\projects\workspace\springapp\war\WEB-INF\web.xml to C:\apache-tomcat-7.0.8\webapps\c:\projects\workspace\springapp\WEB-INF\web.xml due to failed to create the parent directory for C:\apache-tomcat-7.0.8\webapps\c:\projects\workspace\springapp\WEB-INF\web.xml After reviewing the directory: springapp I saw the properties as read-only. No problem I thought as I'm logging in as administrator. However, changing the uac settings, going to a command prompt as admin and then trying to change the properties of the folder with attrib, making me the owner of the folder, changing the security settings etc... did nothing. I can't seem to change this folder to anything. So my question is, how do I change the settings on that folder so ANT can make changes to that folder?

• Block (or only allow certian) incoming IP addresses on Verizon FIOS Actiontec Router

  - by jmlumpkin

  I opened a few ports to the outside of my home network so I can get into a few of my machines from outside. When checking some logs, I noticed that I was getting scanned on some ports from various other countries. I already moved my port forward to a non-standard port. I would like to be able to block specific IP's (or even subnets) from my Verizon FIOS router. There is a little bit of documentation online, but I can't find anything specific on how to do this. To start, I just want to block a specific IP. But if it is not to hard, I would also like to know how to possibly block a range of IPs. And with the inverse of this - is there a way to allow only certain IPs or range?

• Copy-paste stops working on Windows 7

  - by earlyadopter

  Copy-paste functionality stops working after about an hour after each reboot on a Windows 7 64-bit system. Running Google Chrome (with gmail and few other tabs open like Calendar, Reader), MS Outlook (which I don't think has anything to do with the problem — I saw it when outlook was off as well), iTunes (9.1.1.12 if it matters). Would appreciate hints where and what for to look in a registry, and ideas for possible fix. That is not an Internet Explorer problem (I don't even run it) — it happens in all applications. Neither Ctrl-C/Ctrl-V nor context menu right-click Copy-Paste (actually, nothing happens on Copy, so there is nothing in a clipboard to Paste) are working. Drag-and-Drop (where supported) continues working though.

• Why does deleting from the command line take significantly less time than from a GUI?

  - by Jordan Plahn

  So this is probably the dumbest question you'll read today, but it's something I just wondered about as I was deleting a dozen or so images from my computer. With a quick rm -rf command on the directory's contents, all the images were gone in a snap. When I drag the same dozen or so images to a trash can/recycle ban, it takes sometimes 10 seconds or more. Now I'm sure some of it comes from the overhead of the GUI and such, and some of it may be the fact that the file still "exists" in some form if it's put into the recycle bin, but is there anything else that accounts for such a huge time disparity? Are "rm" and "delete" just such fundamentally different commands so I'm trying to compare apples and oranges? Enlighten me, please!

• How can we implement network search for Windows AND OS X clients?

  - by michielvoo

  We have a network with Windows 7 and OS X (10.5 and 10.6) computers. Our servers run on Windows Server 2003 (1 Small Business Server, 2 Standard). We need to be able to search through about 15.000 - 30.000 documents in our archives. The best solution would be if users can search directly from the Windows menu (on Windows 7) or the Spotlight menu (on OS X 10.5 and 10.6). Also good would be if users can search directly from the search bar in their browsers, or by first visiting a site with the search form. In case the users search through the browser, it's important they they are able to open a file in the search results just by clicking on it. I have tested Microsoft Search Server Express, but it doesn't meet the requirements (no OS X support, results in the browser can't be opened by clicking in anything but Internet Explorer). I have looked at Spotlight server, but that only supports OS X. Thanks!

• Mozilla Persona to the login rescue?

  - by Matt Watson

  A lot of website now allow us to login or create accounts via OAuth or OpenID. We can use our Facebook, Twitter, Google, Windows Live account and others. The problem with a lot of these is we have to have allow the websites to then have access to our account and profile data that they shouldn't really have. Below is a Twitter authorization screen for example when signing in via Technorati. Now Technorati can follow new people, update my profile and post tweets? All I wanted to do was login to Technorati.com to comment on a post!Mozilla has just released their new solution for this called Persona. First thought is oh great another solution! But they are actually providing something a little different and better. It is based on an email address and isn't linked to anything like our personal social networks or their information. Persona only exists to help with logging in to websites. No loose strings attached.Persona is based on a new standard called BrowserID and you can read more about it here:How BrowserID Works.  The goal is to integrate BrowserID in to the browser at a deeper level so no password entry is required at all. You can tell your web browser to just auto sign in for you. I am really hoping this takes off and will look at implementing it in current projects! I would recommend researching it and lets hope it or something like it becomes a wide spread reality in the future.

• Crossplatform "jail" for an application

  - by Alexander

  We currently have a variety of systems (Linux, Solarix, *BSD, HP-UX ...) on which we are not allowed to install anything into / (but I have root access. That's strange, I know). But we'd like to run Puppet on all of them. So, the obvious idea is to install Puppet with all prebuilt dependencies into some isolated tree, something like "jail", which will allow to use dependences from some prefix and to access the host system. The big advatanges would be uniform deployment and updates. One solution that came to my mind is to deploy Gentoo Prefix, and install Puppet there with package manager. However, this requires a lot of extra space and some manual patching for each system. Maybe there are some more elegant and simple solutions?

• What is the best resource or method for learning more about servers and networking?

  - by kaleidomedallion

  I can get around a server to some degree, but everything I have learned has been as I have needed to learn it. Every once in a while I will learn about some new command that will revolutionize how I think about systems and networking, and realize how I could have been using it this whole time if only I had known about it. Anything to bring someone from novice to some kind of fluency? Do I just need to earn the battle scars bit by bit over the course of years? (I mean of course I do but what can I do to help it be not quite so painful?) For instance, I am still fuzzy on all of networking. Any help would be greatly appreciated.

• Snow Leopard, PHP, and MySQL

  - by Peter

  I have just installed Snow Leopard and now my PHP/MySQL program ends in a "Segmentation fault". I have been searching the web for a solution, I realize that there are some issues with SL/PHP/MySQL, but I have not found anything that works yet. I downloaded the binary MySQL package mysql-5.1.42-osx10.6-x86_64. I have updated the php.ini file as suggested at various posts. When I run PHP and connect to the MySQL server the behavior is a bit random. In many cases it works fine to connect and read data. In my specific case the PHP program constructs a LOAD DATA LOCAL INFILE ... statement to load data from a text file. It should do several such queries after each other in a loop. It works one time but the halts in a "Segmentation fault". The program worked fine in Leopard, but not now. My versions are: OS 10.6.2, PHP 5.3.0, MySQL 5.1.42

• Installing then Running VMware or VirtualBox causes my Windows 7 PC to not boot up after shutting down?

  At my work I am provided with a Windows 7 PC but I am a programmer and Windows gives me problems for doing some types of development so I want to have a virtual Ubuntu Linux machine that I can use for some things. However, I have tried with both VirtualBox and VMware and I am able to install the latest Ubuntu and run it but then when I try to restart / start the computer after it was shut down, I am unable to boot into Windows normally and end up having to go into Safe mode and then use the system restore to get my system back up and working. I am puzzled by this and would appreciate if anyone has any idea why it would be doing this, I have searched on this but can't find anything. Thanks for any advice

• Is a Hostname A Entry necessary?

  - by Citizen

  When I log into WHM, I get this message: The server was unable to lookup an an A entry for its hostname (server226.taxi.com). This is generally because the entry was never added. However this could also be the result of your nameserver(s) being down. If you would like to attempt to automatically add the entry, click here. If I click "here" it does nothing and I still get the message. I'm not hosting websites for other people, just internal projects on our server. Does not having an A Hostname Record affect SEO or anything like that or is this just a convenience when setting up nameservers or something like that?
