• How to deal with fellow programmer who likes to delegate task with lack any support from boss [closed]

  - by Rudy

  I have a problem with my fellow programmer. We are currently working together in a small project that need to be shipped every 2 weeks. She has a tendency to ask for help for every issues that she is facing. Whether it's a compile error, algorithm problem or even sync/merge issue that caused by herself. She does not even bother to check Google or try to find out by herself. I can be asked to help her for 5-10 times a day. Everyday her husband keeps calling (4-6 times a day), and most of the code that has been delivered by her are actually incorrect. Today she framed me for sending the wrong delivery product. She went home after lunch on the delivery day without telling PM and other team member on that day and her code she commited does not work at all. It's not even tested. I have no choice to roll back her code and cleaning her code just for sake to able to run the product. I have warned her about her defective codes for almost 3 iterations. She said when she was not around I should be able to test her module for her. I snapped and yelled that I am not her slave and directly reported to my boss. However, my boss is not a person that can manage and care about software quality. What is the most important thing to my boss is delivery of product, whether it tested or not. He can even asked us to deliver something that not even tested by QA to the client, on the next day. Most of our suggestion is not followed by him. He even asked me to apologize to her because I snapped. I am tired of the whole situation. This kind of thing keeps repeated. I do have saving to be able to survive for 6 months and the idea of resigning is keep haunting. There is nothing else that can be learned in my current job and I had been in a better environment than this. What should I do with the situation?

• High-Powered Sites for low Cost

  - by HighAltitudeCoder

  Ahh, I am experiencing the intimidation of my very first post - visible by the whole world. Ok, here goes.   This first post is nothing exceptional.  It is simply a recommendation based (fittingly, I suppose) upon the job search you may be gearing up for.  I find myself in this very situation right now.  And, I will take my own recommendation after posting this entry. Job-Seekers: To the left you will notice two links under "Recommended Learning".  I have found these links to be invaluable when it comes to re-tooling, re-familiarizing, or otherwise resharping my skills when looking for that next job. Often, you will find job-postings with the text, usually posted after a laborious list of qualifications indicating the company's desire to hire candidates who know what they are doing: "...Looking for a candidate who can hit the ground running...".  The interesting thing about this post to me is I've encountered many individuals who, after speaking and working with them for some time, I've realized are perfectly capable of hitting the ground running - and FAST.  But what if they speed off in the wrong direction? The next time you spearhead a major task in your job, ask yourself: Am I headed in the wrong direction?  There are many ways to do this.  In fact, I've found in this new field there are more tempting ways to steer your project in the wrong direction than there are good ones.  I don't want to suggest that every one of my posts will fall into the "right direction" category, however I do think a healthy dose of introspection of the pros and cons will always be beneficial before you set off. That said, allow me to expound on the previously mentioned links. These web sites are invaluable.  They demonstrate the capabilities of existing as well as new and upcoming tools available in several IDE's.  I've viewed many tutorials in LearnVisualStudio.NET, and only one or two so far in TrainingSpot, however I've been delighted in their simplicity and straightforward approach to proper usage of the particular tool or concept being discussed.  They have not (so far in my experience) demonstrated ways in which to use the tools that become cumbersome, impractical, or error-prone. Each website has step-by-step videos that can be paused, replayed, and most importantly, they are done in real time.  As the author is typing, the viewer gets to experience the coding experience from a first-person perspective, including syntax errors, unexpected behaviors, IDE setup idiosyncracies, everything.  A subtle value I've gained from these videos is that a certain degree of confusion and introspection is normal when working with new tools and exploring new paths.  They (as well as your own experience) are not to be feared, but enjoyed.  I highly recommend them. Good work, guys!

• How to be successfull at BDD Specifications Workshops?

  - by sigo

  Today we tried to introduce BDD in our software development process by having a specification workshop. For this workshop we had 2 developers, 1 tester and 1 business analyst. The workshop lasted 1h30 and by the end of it we managed to figure out some BDD scenarios for our new feature. We tried to focus on finding the scenarios that we could miss, and the difficult ones. At the end of the workshop some people were actually unhappy with the workshop. One developer felt he wasted his time as he was used to be given out the scenarios directly by the business analyst and review them with her. The business analyst didn't feel confident with our scenario coverage (Had a feeling that we could have missed out other important stuff) but more importantly felt that this workshop was also a waste of time as she could have figured out all these scenarios by herself and in a shorter period of time. So my question is how that kind of workshop can actually work. In the theory, given you have a new feature to develop, you put the tree 'amigos' (dev/tester/ba) in the same room so that they can collaborate together on writing the differents requirements for the new feature using examples. I can see all the benefits from that. Specially in term of knowledge sharing and common product/end goal/done vision. But in practice, we still think it is more cost effective to first have a BA to work on his own on the examples and only then to have the scenarios to be reviewed/reworked by the 3 'amigos'. By having the BA to work on his own, we actually feel more confident that we are less going to miss out stuff + we still get to review the scenarios afterward to double check. We don't think than simple brainstorming/deliberate discovery is actually enought to seriously cover all the requirement for a feature. The business analyst is actually the best person for that kind of stuff. The thing we just do is to review what she wrote and see if then we have a common understanding (which could then lead to rewrite some of her scenarios or add new ones she could have missed). This workshop lasted 1h30, and by the end of it, we didn't feel confident enought about wha we did...sure we could have spent more time on it but honestly most people get exhausted after 1h30 of brainstorming. So how can you get that to work effectively in practice ?

• LibGDX - Textures rendering at wrong position

  - by ACluelessGuy

  Update 2: Let me further explain my problem since I think that i didn't make it clear enough: The Y-coordinates on the bottom of my screen should be 0. Instead it is the height of my screen. That means the "higher" i touch/click the screen the less my y-coordinate gets. Above that the origin is not inside my screen, atleast not the 0 y-coordinate. Original post: I'm currently developing a tower defence game for fun by using LibGDX. There are places on my map where the player is or is not allowed to put towers on. So I created different ArrayLists holding rectangles representing a tile on my map. (towerPositions) for(int i = 0; i < map.getLayers().getCount(); i++) { curLay = (TiledMapTileLayer) map.getLayers().get(i); //For all Cells of current Layer for(int k = 0; k < curLay.getWidth(); k++) { for(int j = 0; j < curLay.getHeight(); j++) { curCell = curLay.getCell(k, j); //If there is a actual cell if(curCell != null) { tileWidth = curLay.getTileWidth(); tileHeight = curLay.getTileHeight(); xTileKoord = tileWidth*k; yTileKoord = tileHeight*j; switch(curLay.getName()) { //If layer named "TowersAllowed" picked case "TowersAllowed": towerPositions.add(new Rectangle(xTileKoord, yTileKoord, tileWidth, tileHeight)); // ... AND SO ON If the player clicks on a "allowed" field later on he has the opportunity to build a tower of his coice via a menu. Now here is the problem: The towers render, but they render at wrong position. (They appear really random on the map, no certain pattern for me) for(Rectangle curRect : towerPositions) { if(curRect.contains(xCoord, yCoord)) { //Using a certain tower in this example (left the menu out if(gameControl.createTower("towerXY")) { //RenderObject is just a class holding the Texture and x/y coordinates renderList.add(new RenderObject(new Texture(Gdx.files.internal("TowerXY.png")), curRect.x, curRect.y)); } } } Later on i render it: game.batch.begin(); for(int i = 0; i < renderList.size() ; i++) { game.batch.draw(renderList.get(i).myTexture, renderList.get(i).x, renderList.get(i).y); } game.batch.end(); regards

• What is hiberfil.sys and How Do I Delete It?

  - by The Geek

  You’re no doubt reading this article because there’s a gigantic hiberfil.sys file sitting in the root of your drive, and you want to get rid of it to free up some space… but you can’t! Luckily, you actually can delete it, and today we’ll show you how. The more memory you have in your PC, the bigger the file will be. So What is hiberfil.sys Anyway? Windows has two power management modes that you can choose from: one is Sleep Mode, which keeps the PC running in a low power state so you can almost instantly get back to what you were working on. The other is Hibernate mode, which completely writes the memory out to the hard drive, and then powers the PC down entirely, so you can even take the battery out, put it back in, start back up, and be right back where you were. Hibernate mode uses the hiberfil.sys file to store the the current state (memory) of the PC, and since it’s managed by Windows, you can’t delete the file. So if you never use it, and want to disable Hibernate mode, keep reading. Personally I stick with Sleep Mode the vast majority of the time, but I do use Hibernate quite often. Disable Hibernate (and Delete hiberfil.sys) in Windows 7 or Vista You’ll need to open an administrator mode command prompt by right-clicking on the command prompt in the start menu, and then choosing Run as Administrator. Once you’re there, type in the following command: powercfg -h off You should immediately notice that the Hibernate option is gone from the Shut down menu. You’ll also notice that the file is magically gone! For more about dealing with Hibernate like setting how long it takes to head into Hibernate mode, you can check out our article on How to Manage Hibernate Mode in Windows 7. Disabling Hibernate Mode in Windows XP It’s a lot easier in Windows XP to get rid of Hibernate mode… in fact, we’ve already covered it before, but we’ll cover it again. Just head into Control Panel –> Power Options, and then find the Hibernate tab. Uncheck the box, reboot your PC, and then you can delete the hiberfil.sys file.

• Is it reasonable to insist on reproducing every defect before diagnosing and fixing it?

  - by amphibient

  I work for a software product company. We have large enterprise customers who implement our product and we provide support to them. For example, if there is a defect, we provide patches, etc. In other words, It is a fairly typical setup. Recently, a ticket was issued and assigned to me regarding an exception that a customer found in a log file and that has to do with concurrent database access in a clustered implementation of our product. So the specific configuration of this customer may well be critical in the occurrence of this bug. All we got from the customer was their log file. The approach I proposed to my team was to attempt to reproduce the bug in a similar configuration setup as that of the customer and get a comparable log. However, they disagree with my approach saying that I should not need to reproduce the bug (as that is overly time-consuming and will require simulating a server cluster on VMs) and that I should simply "follow the code" to see where the thread- and/or transaction-unsafe code is and put the change working off of a simple local development, which is not a cluster implementation like the environment from which the occurrence of the bug originates. To me, working out of an abstract blueprint (program code) rather than a concrete, tangible, visible manifestation (runtime reproduction) seems like a difficult working environment (for a person of normal cognitive abilities and attention span), so I wanted to ask a general question: Is it reasonable to insist on reproducing every defect and debug it before diagnosing and fixing it? Or: If I am a senior developer, should I be able to read (multithreaded) code and create a mental picture of what it does in all use case scenarios rather than require to run the application, test different use case scenarios hands on, and step through the code line by line? Or am I a poor developer for demanding that kind of work environment? Is debugging for sissies? In my opinion, any fix submitted in response to an incident ticket should be tested in an environment simulated to be as close to the original environment as possible. How else can you know that it will really remedy the issue? It is like releasing a new model of a vehicle without crash testing it with a dummy to demonstrate that the air bags indeed work. Last but not least, if you agree with me: How should I talk with my team to convince them that my approach is reasonable, conservative and more bulletproof?

• Are there software options (preferabbly .NET) for doing distance and speed analysis of footballers moving on video?

  - by Anonymous Type

  Editing Question for Clarity Thanks for feedback so far, very insightful. I'm not sure how far along this part of the software community is, and what if any libraries exist for me to leverage from. Heres what I'm trying to do. Problem: Take an existing video of a game of rugby league. The Rugby League field is 100 metres long, 70 metres wide, and has white line markings every 10 metres running along the width of the field, as well as along the sidelines. Each side has 13 players on the field. Players on each team have identical jerseys that normally constrast strongly against background colours (green/brown field colour) and the referee's colour (usually yellow) and the designated water runner (orange). All players have a unique number in thick white lettering on their backs for identification. Video is taken with a high definition camera. Currently only one camera is used (2D) and existing video does not contain a foreground object of fixed spatial dimensions (as suggested in one answer for comparision measurements, however I could add this to future filming sessions if it is worthwhile). The player's do not run in a straight line 50% of the time but will go sideways on on a diagonal to the play the ball. The distance measured always starts from the spot of the previous "tackle", which ends where the player stops forward movement. It is not always possible to determine the players number from the video (facing other direction, sunlight, others standing in the way of the camera). But this isn't important as the software could allow for manual inputting of unknown "runs" at a later point after analysis. Determine the distance between two points (i.e. where the player started his "run" and where he finished it). I'm guessing that this would be quite doable if I manually marked the start and end point in the video. But how would I use landmarks in the background to determine the distance (assuming the person taking the video has kept it from jerking around). Question: Do software packages or libraries exist that are specialised enough to assist with writing analysis software to determine a sports persons distance travelled based on video taken of the performance?

• Tiling Problem Solutions for Various Size "Dominoes"

  - by user67081

  I've got an interesting tiling problem, I have a large square image (size 128k so 131072 squares) with dimensons 256x512... I want to fill this image with certain grain types (a 1x1 tile, a 1x2 strip, a 2x1 strip, and 2x2 square) and have no overlap, no holes, and no extension past the image boundary. Given some probability for each of these grain types, a list of the number required to be placed is generated for each. Obviously an iterative/brute force method doesn't work well here if we just randomly place the pieces, instead a certain algorithm is required. 1) all 2x2 square grains are randomly placed until exhaustion. 2) 1x2 and 2x1 grains are randomly placed alternatively until exhaustion 3) the remaining 1x1 tiles are placed to fill in all holes. It turns out this algorithm works pretty well for some cases and has no problem filling the entire image, however as you might guess, increasing the probability (and thus number) of 1x2 and 2x1 grains eventually causes the placement to stall (since there are too many holes created by the strips and not all them can be placed). My approach to this solution has been as follows: 1) Create a mini-image of size 8x8 or 16x16. 2) Fill this image randomly and following the algorithm specified above so that the desired probability of the entire image is realized in the mini-image. 3) Create N of these mini-images and then randomly successively place them in the large image. Unfortunately there are some downfalls to this simplification. 1) given the small size of the mini-images, nailing an exact probability for the entire image is not possible. Example if I want p(2x1)=P(1x2)=0.4, the mini image may only give 0.41 as the closes probability. 2) The mini-images create a pseudo boundary where no overlaps occur which isn't really descriptive of the model this is being used for. 3) There is only a fixed number of mini-images so i'm not sure how random this really is. I'm really just looking to brainstorm about possible solutions to this. My main concern is really to nail down closer probabilities, now one might suggest I just increase the mini-image size. Well I have, and it turns out that in certain cases(p(1x2)=p(2x1)=0.5) the mini-image 16x16 isn't even iteratively solvable.. So it's pretty obvious how difficult it is to randomly solve this for anything greater than 8x8 sizes.. So I'd love to hear some ideas. Thanks

• Did I choose proper career path? [closed]

  - by Liston Catch

  I am a C# Junior. My company has it's own enterprise documents-flow system written, my job along with 10 other programmers is to write modules/add-ons for it. I am totally bored of this job, I dont like Microsoft's technologies stack (dont hate me here, just subjective), but it's plain boring, enterprise is boring (subjective again, everyone's tastes differ), days on this work last long and I am tired of it. In short - I dont like my job. In my spare time I am doing PHP-development and I totally like it. I am also doing web-design, so I am LAMP-kind of guy who loves his Ubuntu and does design aswell. I know that most programmers don't do design themselves, so some person is either all about design or all about coding, but I enjoy both and do both. I often get interesting sites orders, I love to make whole websites with all the design, I love the feeling of site completeness, I enjoy talking with customers. I like that PHP is simple and skill cap is lower than one of java, meaning I can become expert in it after some years. But C# (and J2EE also) pay more, and I am doing really good in C#. But I dont like it. I can go for J2EE, platform itself seems more fun to me rather than .NET, but EE development is still boring to me. But it seems higher payed, easier to find job (since PHP is too common for its easiness. But if you are expert in something it doesnt matter, right? Just a higher skillcap.) Question: I want to go on with freelance. I want to have an opportunity to start my own startup in web. Actually I have a browser-game already written by myself, it earns me around 500$ per month which I am really proud of since I am 21 only and still noob in coding. I want to find part-time PHP job. 3 days per week so I can get some stable income, I can work in team and learn from them, social factor matters aswell as ensurance and diversity. I also want my total income (freelance + part-time job + own startup maybe)to be not too much less than one I have working in EE development sector. Maximum of 25% lower, but not more. Is it all possible if I stick with web-development (LAMP + HTML/CSS/JS/Jquery/AJAX)? Or is it easier to reach my goals with EE development?

• Looking for an algorithm to connect dots - shortest route

  - by e4ch

  I have written a program to solve a special puzzle, but now I'm kind of stuck at the following problem: I have about 3200 points/nodes/dots. Each of these points is connected to a few other points (usually 2-5, theoretical limit is 1-26). I have exactly one starting point and about 30 exit points (probably all of the exit points are connected to each other). Many of these 3200 points are probably not connected to neither start nor end point in any way, like a separate net, but all points are connected to at least one other point. I need to find the shortest number of hops to go from entry to exit. There is no distance between the points (unlike the road or train routing problem), just the number of hops counts. I need to find all solutions with the shortest number of hops, and not just one solution, but all. And potentially also solutions with one more hop etc. I expect to have a solution with about 30-50 hops to go from start to exit. I already tried: 1) randomly trying possibilities and just starting over when the count was bigger than a previous solution. I got first solution with 3500 hops, then it got down to about 97 after some minutes, but looking at the solutions I saw problems like unnecessary loops and stuff, so I tried to optimize a bit (like not going back where it came from etc.). More optimizations are possible, but this random thing doesn't find all best solutions or takes too long. 2) Recursively run through all ways from start (chess-problem-like) and breaking the try when it reached a previous point. This was looping at about a length of 120 nodes, so it tries chains that are (probably) by far too long. If we calculate 4 possibilities and 120 nodes, we're reaching 1.7E72 possibilities, which is not possible to calculate through. This is called Depth-first search (DFS) as I found out in the meantime. Maybe I should try Breadth-first search by adding some queue? The connections between the points are actually moves you can make in the game and the points are how the game looks like after you made the move. What would be the algorithm to use for this problem? I'm using C#.NET, but the language shouldn't matter.

• How to set up an rsync backup to Ubuntu securely?

  - by ws_e_c421

  I have been following various other tutorials and blog posts on setting up a Ubuntu machine as a backup "server" (I'll call it a server, but it's just running Ubuntu desktop) that I push new files to with rsync. Right now, I am able to connect to the server from my laptop using rsync and ssh with an RSA key that I created and no password prompt when my laptop is connected to my home router that the server is also connected to. I would like to be able to send files from my laptop when I am away from home. Some of the tutorials I have looked at had some brief suggestions about security, but they didn't focus on them. What do I need to do to let my laptop with send files to the server without making it too easy for someone else to hack into the server? Here is what I have done so far: Ran ssh-keygen and ssh-copy-id to create a key pair for my laptop and server. Created a script on the server to write its public ip address to a file, encrypt the file, and upload to an ftp server I have access to (I know I could sign up for a free dynamic DNS account for this part, but since I have the ftp account and don't really need to make the ip publicly accessible I thought this might be better). Here are the things I have seen suggested: Port forwarding: I know I need to assign the server a fixed ip address on the router and then tell the router to forward a port or ports to it. Should I just use port 22 or choose a random port and use that? Turn on the firewall (ufw). Will this do anything, or will my router already block everything except the port I want? Run fail2ban. Are all of those things worth doing? Should I do anything else? Could I set up the server to allow connections with the RSA key only (and not with a password), or will fail2ban provide enough protection against malicious connection attempts? Is it possible to limit the kinds of connections the server allows (e.g. only ssh)? I hope this isn't too many questions. I am pretty new to Ubuntu (but use the shell and bash scripts on OSX). I don't need to have the absolute most secure set up. I'd like something that is reasonably secure without being so complicated that it could easily break in a way that would be hard for me to fix.

• Is it unusual for a small company (15 developers) not to use managed source/version control?

  - by LordScree

  It's not really a technical question, but there are several other questions here about source control and best practice. The company I work for (which will remain anonymous) uses a network share to host its source code and released code. It's the responsibility of the developer or manager to manually move source code to the correct folder depending on whether it's been released and what version it is and stuff. We have various spreadsheets dotted around where we record file names and versions and what's changed, and some teams also put details of different versions at the top of each file. Each team (2-3 teams) seems to do this differently within the company. As you can imagine, it's an organised mess - organised, because the "right people" know where their stuff is, but a mess because it's all different and it relies on people remembering what to do at any one time. One good thing is that everything is backed up on a nightly basis and kept indefinitely, so if mistakes are made, snapshots can be recovered. I've been trying to push for some kind of managed source control for a while, but I can't seem to get enough support for it within the company. My main arguments are: We're currently vulnerable; at any point someone could forget to do one of the many release actions we have to do, which could mean whole versions are not stored correctly. It could take hours or even days to piece a version back together if necessary We're developing new features along with bug fixes, and often have to delay the release of one or the other because some work has not been completed yet. We also have to force customers to take versions that include new features even if they just want a bug fix, because there's only really one version we're all working on We're experiencing problems with Visual Studio because multiple developers are using the same projects at the same time (not the same files, but it's still causing problems) There are only 15 developers, but we all do stuff differently; wouldn't it be better to have a standard company-wide approach we all have to follow? My questions are: Is it normal for a group of this size not to have source control? I have so far been given only vague reasons for not having source control - what reasons would you suggest could be valid for not implementing source control, given the information above? Are there any more reasons for source control that I could add to my arsenal? I'm asking mainly to get a feel for why I have had so much resistance, so please answer honestly. I'll give the answer to the person I believe has taken the most balanced approach and has answered all three questions. Thanks in advance

• Developing a cloud based app

  - by user134897

  I am a company owner that has developed a cloud based app. My code writer has told me how good he is more than once, well, better stated, he did a good job telling me he was better than everyone else in my rather small community. In the last 18 months I have spent nearly 160,000.00 dollars trying to get this company to the "making money" stage. I am now nearly broke, sitting on the edge of a brilliant marketing plan to launch a much needed cloud based app. We did launch our app last year (late 2013), and the feedback was amazing from the users. One user that signed up to use the free app stated that we needed to call him the moment our company goes public because he wants to be the first to buy stock. Now, here's my problem. We did not originally set out to develop a freemium app, we just sort of ended up there by the natural progression of the app. So, now I have an app that really needs to be scrapped and re-built. Although I do feel my code writer has displayed some brilliance in what he has done, he was extremely weak on graphics and every time we speak he tells me there is a newer better way to code that he is trying to learn. So, here's the million dollar question. Ho do I find code writers that already know the newest, best ways to write code? Or maybe better asked, what is the newest best code writing technique? Second, is it even possible to find code writers that are good at graphics? In short, I am nearly broke and need to start over, but I do not know where to find people qualified to write it good the first time around and display good graphic skills. I am trying to build a team of writers instead of just one person. Maybe 3 good at code and two good at graphics, but I am clueless as to what criteria I should use to determine if I am building the right team members. Please help, I am sure you can tell I am fairly lost by my continued rambling.

• TortoiseSVN hangs in Windows Server 2012 Azure VM

  - by ZaijiaN

  Following @shanselman's article on remoting into an Azure VM for development, I spun up my own VS 2013 VM, and that image runs on WS 2012. Once I was able to remote in, I started installing all my dev tools, including Tortoise SVN 1.8.3 64bit. Things went south once I started attempting to check out code from my personal svn server. It would hang and freeze often, although sometimes it would work - I was able to partially check out projects, but I would get frequent connection time out errors. My personal svn server (VisualSVN 2.7.2) runs at home on a windows 7 machine, and I have a dyndns url pointing to it. I have also configured my router to passthrough all 443 traffic to the appropriate port on the server. I self-signed a cert and made sure it was imported into the VM cert store under trusted root authorities. I have no problems connecting to my svn server from 4-5 other computers & locations. From the Azure VM, in both IE and Chrome, I can access the repository web browser with no issues. There are no outbound firewall restrictions. I have installed other SVN add-ons for Visual Studio (AnkhSVN, VisualSVN) and attempted to connect with my svn server, with largely the same results - random and persistent connection issues (hangs/timeouts). I spun up a completely fresh WS 2008 Azure VM, and installed TortoiseSVN, and had the same results. So I'm at a loss as to what the problem is and how to fix it. Web searches on tortoisesvn and windows server issues doesn't yield any current or relevant information. At this point, i'm guessing that maybe some setting or configuration that MS Azure VM images is the culprit - although I should probably attempt to spin up my own local WS VM to rule out that it's a window server issue. Any thoughts? I hope I'm just missing something really obvious!

• Problem with XLSX file on Office 2003 with Compatibility Pack

  - by MadBoy

  I've this machine which has Office 2003 installed with Compatibility Pack. User received one file which she has to work with in XLSX format (file has to stay in that format so options to save it as XLS can be skipped). When she opens the file from Desktop or any other location it gives an error like "Cannot find the file in following location" and in the background it starts Converting XLSX file to XLS. In the end Excel is opened up with some random file name X000008.xls (Read Only) which is just 1 to 1 conversion of the XLSX document. However if I go directly to Excel and use File / Open and try to open the XLSX file no error or conversion is done. The file is writable and can be saved in XLSX format. The file name is simple like This_file something.XLSX, I've even tried to remove all spaces but it gave no better results. Anyone has any recommendations? So far I have done: 1. Uninstalled Compatibility Pack and installed it again. Tried opening it without any other updates and the error still pops out. In progress: I am now running all possible updates of office (like 5 of them) which i suppos won't fix anything (as they were applied when I've uninstalled compatibility pack). Next in run will be (not yet done) installing Windows XP SP3. What other things I can do?

• Event ID: 861 - The Windows Firewall has detected an application listening for incoming traffic

  - by Chris Marisic

  Firstly, my machines aren't compromised any person suggesting such will be DV'd. The security logs on some of my networks client machines (all Windows Xp Sp3) get filled with these useless error messages. Security Failure Audit Detailed Tracking Event ID: 861 User: NT AUTHORITY\NETWORK SERVICE The Windows Firewall has detected an application listening for incoming traffic. Name: - Path: C:\WINDOWS\system32\svchost.exe Process identifier: 976 User account: NETWORK SERVICE User domain: NT AUTHORITY Service: Yes RPC server: No IP version: IPv4 IP protocol: UDP Port number: 55035 Allowed: No User notified: No It's always on various random ports of UDP so setting up a port exception isn't really an option. It's always from svchost or lsass both of which are running services from DLLs. One of the most offending processes seems to the be DnsCache. I have in my global policy under AT < Network < Network Connection < Widnows Firewall < Domain Profile (I haven't changed any standard profile options do both need configured? To allow remote administration and desktop exceptions and have a custom program exception list that has %SystemRoot%\system32\svchost.exe:*:enabled:svchost (Windows won't allow you to add this exception on a local machine but it let me have it on here in the global policy it just doesn't seem to do anything) %SystemRoot%\system32\lsass.exe:*enabled:lsass (I think this one ended all of my LSASS messages) %SystemRoot%\system32\dnsrslvr.dll:*:enabled:dnscache (I tried adding the dll itself to the exception list, this didn't seem to do anything) Is there really any other options left other than disabling the Windows Firewall entirely, disabling auditing entirely or just changing the event viewer to just auto overwrite when needed? I'd much rather fix the problem and get rid of these entries ever being created instead of just trying to cover up the problem.

• Commvault Oracle RMAN Restore to new host

  - by Glenn Stauffer

  We use Commvault Simpana 8 and I have a situation where I have backups of an Oracle database on tape that were taken from Host A. Host A suffered a disk failure (lost its raid configuration) and the sys admins are trying to restore it; in the meantime, I'd working to bring the database back up on another host - Host B. I'm running into problems and am trying to sort out the parameters that need to be passed to the Commvault media agent to get this to work. Unfortunately, I do not have access to Commvault support and the backup person is unavailable. Any one have a clue? The backups are there and the media agent reported a successful write when they ran last night. This is what fails: RMAN run { allocate channel t1 device type sbt_tape parms='SBT_LIBRARY=/usr/local/galaxy/Base/libobk.so,BLKSIZE=262144, ENV=(CvClientName=dbsrv2,CvInstanceName=Instance001, CVOraRacDBName=BBDB, CVOraRACDBClientName=BBDB)'; restore spfile to pfile '/tmp/bbdb.ora' from autobackup; }2 3 4 allocated channel: t1 channel t1: sid=34 devtype=SBT_TAPE channel t1: CommVault Systems for Oracle: Version 7.0.0(Build76) Starting restore at 09-MAY-10 channel t1: looking for autobackup on day: 20100509 channel t1: autobackup found: c-3941155360-20100509-01 released channel: t1 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of restore command at 05/09/2010 18:01:35 ORA-19870: error reading backup piece c-3941155360-20100509-01 ORA-19507: failed to retrieve sequential file, handle="c-3941155360-20100509-01", parms="" ORA-27029: skgfrtrv: sbtrestore returned error ORA-19511: Error received from media manager layer, error text: sbtrestore: Job[0] thread[26316]: InitializeCLRestore() failed.

• Can't access SQL Server 2008 from workstations, but can from server

  - by Kev

  We have an app that can use mssql2k or 2k8. We've been using 2k but I decided to try 2k8 to compare. I installed in on our win2k3 server alongside mssql2k. In the ODBC applet on the server, I was able to set up access to 2k8, and it passes the test at the end successfully, whether I tell it to use Windows Authentication or an sql login. The latter is how the app always accessed mssql2k. The app works fine from the server, but when I try it on a workstation (winxpsp3), I get a window titled, "Microsoft SQL Server Login" that says: Connection failed: SQLState: '01000' SQL Server Error: 53 [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()). Connection failed: SQLState: '08001' SQL Server ERror: 17 [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. Then I get the ODBC login dialog, which I can't get to login correctly (I just keep getting the same error above), even copying and pasting a password after resetting it on the server, and whether "trusted" is checked or not. "Options" is disabled. The server was straight SERVERNAME for mssql2k, but for mssql2k8 it's called SERVERNAME\mssql2008. That works on the server, why not on the workstation? (Which I'm logged in as the same person on, BTW.)

• Telnet does not give a response

  - by floorish

  Some wireless access points are acting a little weird, so I want to reboot them every couple of hours. Luckily there exists a security flaw which lets me login as root through telnet when using port 1111 (without username and password). Now I want to use that to let my QNAP NAS execute the reboot command through telnet every now and then. The problem is however that that telnet version doesn't give any response if I connect to the AP. The telnet I use on OSX works just fine but the one on the NAS not. BusyBox v1.01 (2012.06.14-18:35+0000) multi-call binary Usage: telnet [-a] [-l USER] HOST [PORT] When I execute telnet <HOST> 1111 nothing happens. I can send the escape character ^] which gives me the following options: Console escape. Commands are: l go to line mode c go to character mode z suspend telnet e exit telnet The only way to get some commands executed is by suspending telnet with z followed by some random command which isn't recognized. Then the prompt shows this: # telnet 192.168.1.5 1111 ^] Console escape. Commands are: l go to line mode c go to character mode z suspend telnet e exit telnet z continuing... asdf Illegal command. 00> After that I am able to communicate with the AP, but when I exit the telnet session and try the same again, the AP refuses to connect at all and it must be manually rebooted (looks like the telnet session isn't shut down properly on the AP). So the question is what commands should I execute in order to communicate with the AP using the Busybox telnet version of the QNAP? (No, can't use ssh unfortunately)

• Apache is reponding a blank white page

  - by Bruno Araujo

  I have the following situation: A site hosted in apache 2.4, with ssl, that works like a charm for a while now, but out of no where, without modifications to the site, apache started serving random blank pages.

• Active RDP session over VPN getting disconnected

  - by Wandering Penguin

  I am having seemingly random disconnects of active RDP sessions (I am actively typing or otherwise interacting with the desktop) when connected over the VPN connection. The attempted to reconnect 1/20 pops up and proceeds all the way through 20 then drops. Once the session drops I can open a new session and connect again. This started happening about a week ago, The VPN connection is an IPSec VPN connection from a SonicWall NSA 2400. The NIC drivers are up to date. The VPN client is up to date. The firmware on the SonicWall is up to date (both regular and the early-release versions work the same). I have attempted to connect over three ISPs all with the same behavior. Two different workstations were used to test the VPN connection. The same behavior occurs when connecting to a domain workstation or server. If I am within the firewall I can connect to the same workstations and servers with the disconnect. The VPN connection has "enable fragmented packet handling" and "ignore DF (don't fragment) bit" set. Is there something I am missing in where I am looking for the problem?

• Debian Apache2 and SSL

  - by Topher Fangio

  Hello all, I recently took over a server that is using Apache2 with SSL. I have setup a new server to which I am migrating all of the old websites so that we can more easily scale (it's a cloud server) and so that I can set everything up correctly (or at least with some sort of convention). I have read quite a few articles on setting up Apache2 and SSL with virtual hosts, but I'm a bit confused because all of the examples show three files and I only seem to have two. To compound the problem, they are all named differently (do the file extensions actually make a difference?). The examples show something to this effect: <VirtualHost X.X.X.X:443> ServerAlias something.mydomain.com ServerAdmin [email protected] DocumentRoot /var/www/project/client/site SSLEngine on SSLCertificateFile /etc/ssl/certs/mydomain-cert.pem SSLCertificateKeyFile /etc/ssl/private/mydomain-key.pem SSLCertificateChainFile /etc/ssl/certs/mydomain-ca.crt </VirtualHost> However, the files I have are: _.mydomain.com.crt gd_bundle.crt It is a wildcard certificate that we purchased through GoDaddy I believe. I believe that the first file is the actual certificate file and the gd_bundle.crt is the chain file, but that leaves me without a key file. There is also a random mydomain.csr file lying around on the old server, but it wasn't one of the files bundled with the download from GoDaddy, so I'm not really sure as to what it is. Any help in figuring out what I need to do would be greatly appreciated. I am software developer, so I know my way around computers, but I have only dabbled in server setup/maintenance. Much Thanks!
