  • Windows 7 -Can't get access to shared folder from one computer to another.

    - by Carbonara
    I have 2 windows 7 computers and i'm trying to share a folder (that I want password protection on) outside of the homegroup. Both computers are part of the same workgroup and I have the same user account/password combination on both computers plus I have password protected sharing turned on in the network and sharing centre along with file and printer sharing turned on. On computer 1 I have right clicked and selected that I want the folder shared. When I navigate via the network on computer 2 to computer 1 the shared folder shows up on computer 2 but double clicking on it to open it gives me an alert saying I don't have permission to access it, no option to type in the user name and password (according to the help files I shouldn't even need to type the password in if both computers have the same username/password anyway but would need it if I'm logged in as a different user). It's just a blanket denial of access.

  • How to handle environment-specific application configuration organization-wide?

    - by Stuart Lange
    Problem Your organization has many separate applications, some of which interact with each other (to form "systems"). You need to deploy these applications to separate environments to facilitate staged testing (for example, DEV, QA, UAT, PROD). A given application needs to be configured slightly differently in each environment (each environment has a separate database, for example). You want this re-configuration to be handled by some sort of automated mechanism so that your release managers don't have to manually configure each application every time it is deployed to a different environment. Desired Features I would like to design an organization-wide configuration solution with the following properties (ideally): Supports "one click" deployments (only the environment needs to be specified, and no manual re-configuration during/after deployment should be necessary). There should be a single "system of record" where a shared environment-dependent property is specified (such as a database connection string that is shared by many applications). Supports re-configuration of deployed applications (in the event that an environment-specific property needs to change), ideally without requiring a re-deployment of the application. Allows an application to be run on the same machine, but in different environments (run a PROD instance and a DEV instance simultaneously). Possible Solutions I see two basic directions in which a solution could go: Make all applications "environment aware". You would pass the environment name (DEV, QA, etc) at the command line to the app, and then the app is "smart" enough to figure out the environment-specific configuration values at run-time. The app could fetch the values from flat files deployed along with the app, or from a central configuration service. Applications are not "smart" as they are in #1, and simply fetch configuration by property name from config files deployed with the app. The values of these properties are injected into the config files at deploy-time by the install program/script. That install script takes the environment name and fetches all relevant configuration values from a central configuration service. Question How would/have you achieved a configuration solution that solves these problems and supports these desired features? Am I on target with the two possible solutions? Do you have a preference between those solutions? Also, please feel free to tell me that I'm thinking about the problem all wrong. Any feedback would be greatly appreciated.

  • Why does my computer crash when I minimise the last window?

    - by TRiG
    I am runnung Ubuntu 12.04 LTS. If I have a few windows open (say four to six, not a large amount), and minimise all by pressing Ctrl+Super+D, they all minimise immediately with no problems. However, if I minimise them one at a time, by clicking the minimise button with my mouse, the last one often hangs. Usually it will appear as a ghost on the screen for a while, semi-minimised (in other words, shrunk toward the Unity launcher bar, half-size or smaller, and semi-transparent). Usually it will eventually clear; sometimes the computer just freezes and I have to restart it. It doesn’t seem to matter what the window actually is. Just now, I had to restart my computer with Skype* semi-minimised. I’ve seen it freeze before with the Terminal semi-minimised (and the Terminal wasn’t even doing anything at the time). The only pattern is that it’s always the last window minimised which freezes, and that minimising all windows together using the keyboard shortcut works fine. What on earth is going on, and how can I stop it? * I hate Skype, but I need it for work.

  • Can the customer be a SCRUM Product Owner in a project?

    - by Morten
    I just had a discussion with a colleague about the Product Owner role: In a project where a customer organization has brought in a sofware developing organization (supplier), can the role of Product Owner be successfully held by the customer organization, or should it always be held by the supplier? I always imagined, that the PO was the supplier organizations guy. The guy that ensured that the customer is happy, and continously fed with new and high-businessvalue functionality, but still an integral part of the developer organization. However, maybe I have viewed the PO role too much like the waterfall project manager. My colleague made me think: If the customer organization is mature and proffessional enough, why not let a person from their camp prioritize the backlog?? That would put the PO role much closer to the business, thus being (in theory) better to assess the business value of backlog items. To me, that is an intriguing thought. But what are the implication of such a setup??? I look forward to your input.

  • Is it more valuable to double major in Computer Science/Software Engineering or get an undergraduate CS degree with a Masters in SE?

    - by Austin Hyde
    A friend and I (both in college) are currently in a debate over which is better, in terms of employment opportunities, experience, and education: a Bachelors degree in both Computer Science and Software Engineering, or a Bachelors in Computer Science with a Masters in Software Engineering. My point of view is that I would rather go to school for 4-4.5 years to learn both sides of the field, and be out working on real projects gaining real experience, by going the double major route. His point of view is that it would look better to potential employers if he had a Bachelors in CS and Masters in SE. That way, when he's finally done after 4 years of CS and 2-4 of SE (depending on where he goes), he can pretty much have his choosing of what he wants to do. We are both in agreement on the distinction between the two degrees: CS is "traditional" and about the theory of algorithms, data structures, and programming, where SE is the study of the design of software and the implementation of CS theory. So, what's your stance on this debate? Have you gone one route or another? And most importantly, why?

  • Computer Science graduate. Master or full-time job? [closed]

    - by Alex
    Possible Duplicate: Is a Master's worth it? I have just gotten my Bachelor's Degree in Computer Science and I have to make choice. Whether to continue with my full-time job I just got or put the job slightly in the background and concentrate on getting a Master's degree. I am currently working as an embedded C developer in a small company. The cool thing is that, because the team is quite small, my engineering ideas really play a part in the final product. Not to mention that I get to work on very different areas of embedded programming: device drivers and development of a Real Time OS. I am very enthusiastic about my job and what I do. On the other hand, in my country there isn't really a master's degree that focuses on embedded development so my gain from getting this degree will mainly in the field of general computer science knowledge. That being said, is it worth giving up all my spare time which I now use to study different areas of embedded devices and work mainly to get a degree rather than pure knowledge and experience in the field I want to work in?

  • Which method should I use to give the perception the computer is thinking in programming?

    - by Roy
    I want to create a simple game like tic tac toe where the human user is playing against the computer. The computer function takes a couple of milliseconds to run but I would like to make the computer take 5 seconds to make a move. Which method should I use? 1) Create two memory threads. One for the computer and one for the human user. When the computer is taking 5 seconds to imitate thinking, the human user thread is paused for 5 seconds. 2) Disable input devices for 5 seconds using timer or dispatchertimer 3) Any better methods you can think of Thanks!

  • How to unit test internals (organization) of a data structure?

    - by Herms
    I've started working on a little ruby project that will have sample implementations of a number of different data structures and algorithms. Right now it's just for me to refresh on stuff I haven't done for a while, but I'm hoping to have it set up kind of like Ruby Koans, with a bunch of unit tests written for the data structures but the implementations empty (with full implementations in another branch). It could then be used as a nice learning tool or code kata. However, I'm having trouble coming up with a good way to write the tests. I can't just test the public behavior as that won't necessarily tell me about the implementation, and that's kind of important here. For example, the public interfaces of a normal BST and a Red-Black tree would be the same, but the RB Tree has very specific data organization requirements. How would I test that?

  • Organization moving from ASP.NET to WebLogic Portal - training recommendations?

    - by frankadelic
    My organization previously used ASP.NET for web projects. They are now migrating to WebLogic Portal/JEE for all future web projects. My experience as a Lead Developer / Architect is totally with .NET projects. I want to get ramped up on WebLogic/JEE, so I can contribute to future projects. Any training/certification suggestions for WebLogic/JEE, in a 6-month time frame? Assume that I will need to fund my own training, and I am working full time. So, money and time are limited.

  • What is the best answer to give for, "Why do you want to change from your present organization?"

    - by Techmaddy
    At present I am into a very good organization. I am planning to shift because I am not happy with the work that I am getting now. I want to work under a different Manager, but my Manager and team is more dependent on me. I tried so many times, but couldn't change my team. So, I started planning to switch my company. Everyone is asking the same question, "Why do you want to change?". Should I say the truth? I told this in 2 places, but did not see a good response from them. Or is there a better answer that I can give?

  • Can a user be a member of multiple Organization Units (OU) in Active Directory ?

    - by Stormshadow
    Can a user be a member of multiple Organization Units (OU) in Active Directory ? Also, is there a standard format mentioned by Microsoft on how an OU should be created and what its attributes are ? I found this in Wikipedia "However, Organizational Units are just an abstraction for the administrator, and do not function as true containers; the underlying domain operates as if objects were all created in a simple flat-file structure, without any OUs. It is not possible for example to create two user accounts with an identical username in two separate OUs, such as "fred.staff-ou.domain" and "fred.student-ou.domain"."

  • Expectations + Rewards = Innovation

    - by D'Arcy Lussier
    “Innovation” is a heavy word. We regard those that embrace it as “Innovators”. We describe organizations as being “Innovative”. We hold those associated with the word in high regard, even though its dictionary definition is very simple: Introducing something new. What our culture has done is wrapped Innovation in white robes and a gold crown. Innovation is rarely just introducing something new. Innovations and innovators are typically associated with other terms: groundbreaking, genius, industry-changing, creative, leading. Being a true innovator and creating innovations are a big deal, and something companies try to strive for…or at least say they strive for. There’s huge value in being recognized as an innovator in an industry, since the idea is that innovation equates to increased profitability. IBM ran an ad a few years back that showed what their view of innovation is: “The point of innovation is to make actual money.” If the money aspect makes you feel uneasy, consider it another way: the point of innovation is to <insert payoff here>. Companies that innovate will be more successful. Non-profits that innovate can better serve their target clients. Governments that innovate can better provide services to their citizens. True innovation is not easy to come by though. As with anything in business, how well an organization will innovate is reliant on the employees it retains, the expectations placed on those employees, and the rewards available to them. In a previous blog post I talked about one formula: Right Employees + Happy Employees = Productive Employees I want to introduce a new one, that builds upon the previous one: Expectations + Rewards = Innovation  The level of innovation your organization will realize is directly associated with the expectations you place on your staff and the rewards you make available to them. Expectations We may feel uncomfortable with the idea of placing expectations on our staff, mainly because expectation has somewhat of a negative or cold connotation to it: “I expect you to act this way or else!” The problem is in the or-else part…we focus on the negative aspects of failing to meet expectations instead of looking at the positive side. “I expect you to act this way because it will produce <insert benefit here>”. Expectations should not be set to punish but instead be set to ensure quality. At a recent conference I spoke with some Microsoft employees who told me that you have five years from starting with the company to reach a “Senior” level. If you don’t, then you’re let go. The expectation Microsoft placed on their staff is that they should be working towards improving themselves, taking more responsibility, and thus ensure that there is a constant level of quality in the workforce. Rewards Let me be clear: a paycheck is not a reward. A paycheck is simply the employer’s responsibility in the employee/employer relationship. A paycheck will never be the key motivator to drive innovation. Offering employees something over and above their required compensation can spur them to greater performance and achievement. Working in the food service industry, this tactic was used again and again: whoever has the highest sales over lunch will receive a free lunch/gift certificate/entry into a draw/etc. There was something to strive for, to try beyond the baseline of what our serving jobs were. It was through this that innovative sales techniques would be tried and honed, with key servers being top sellers time and time again. At a code camp I spoke at, I was amazed to see that all the employees from one company receive $100 Visa gift cards as a thank you for taking time to speak. Again, offering something over and above that can give that extra push for employees. Rewards work. But what about the fairness angle? In the restaurant example I gave, there were servers that would never win the competition. They just weren’t good enough at selling and never seemed to get better. So should those that did work at performing better and produce more sales for the restaurant not get rewarded because those who weren’t working at performing better might get upset? Of course not! Organizations succeed because of their top performers and those that strive to join their ranks. The Expectation/Reward Graph While the Expectations + Rewards = Innovation formula may seem like a simple mathematics formula, there’s much more going under the hood. In fact there are three different outcomes that could occur based on what you put in as values for Expectations and Rewards. Consider the graph below and the descriptions that follow: Disgruntled – High Expectation, Low Reward I worked at a company where the mantra was “Company First, Because We Pay You”. Even today I still hear stories of how this sentiment continues to be perpetuated: They provide you a paycheck and a means to live, therefore you should always put them as your top priority. Of course, this is a huge imbalance in the expectation/reward equation. Why would anyone willingly meet high expectations of availability, workload, deadlines, etc. when there is no reward other than a paycheck to show for it? Remember: paychecks are not rewards! Instead, you see employees be disgruntled which not only affects the level of production but also the level of quality within an organization. It also means that you see higher turnover. Complacent – Low Expectation, Low Reward Complacency is a systemic problem that typically exists throughout all levels of an organization. With no real expectations or rewards, nobody needs to excel. In fact, those that do try to innovate, improve, or introduce new things into the organization might be shunned or pushed out by the rest of the staff who are just doing things the same way they’ve always done it. The bigger issue for the organization with low/low values is that at best they’ll never grow beyond their current size (and may shrink actually), and at worst will cease to exist. Entitled – Low Expectation, High Reward It’s one thing to say you have the best people and reward them as such, but its another thing to actually have the best people and reward them as such. Organizations with Entitled employees are the former: their organization provides them with all types of comforts, benefits, and perks. But there’s no requirement before the rewards are dolled out, and there’s no short-list of who receives the rewards. Everyone in the company is treated the same and is given equal share of the spoils. Entitlement is actually almost identical with Complacency with one notable difference: just try to introduce higher expectations into an entitled organization! Entitled employees have been spoiled for so long that they can’t fathom having rewards taken from them, or having to achieve specific levels of performance before attaining them. Those running the organization also buy in to the Entitled sentiment, feeling that they must persist the same level of comforts to appease their staff…even though the quality of the employee pool may be suspect. Innovative – High Expectation, High Reward Finally we have the Innovative organization which places high expectations but also provides high rewards. This organization gets it: if you truly want the best employees you need to apply equal doses of pressure and praise. Realize that I’m not suggesting crazy overtime or un-realistic working conditions. I do not agree with the “Glengary-Glenross” method of encouragement. But as anyone who follows sports can tell you, the teams that win are the ones where the coaches push their players to be their best; to achieve new levels of performance that they didn’t know they could receive. And the result for the players is more money, fame, and opportunity. It’s in this environment that organizations can focus on innovation – true innovation that builds the business and allows everyone involved to truly benefit. In Closing Organizations love to use the word “Innovation” and its derivatives, but very few actually do innovate. For many, the term has just become another marketing buzzword to lump in with all the other business terms that get overused. But for those organizations that truly get the value of innovation, they will be the ones surging forward while other companies simply fade into the background. And they will be the organizations that expect more from their employees, and give them their just rewards.

    I'm interested in getting into the gaming industry, but i'm unsure as to whether which degree would help me the most. I also do not have any prior programming knowledge(apart from some basic html). So, do you guys have any opinion on which degree i should pick? please don't mention anything about game development or games programming degrees. You may also compare the 2 degrees with Computer Science degree.

  • Why do camera's aspect ratio look good on computer but not on Android devices?

    - by Pooya Fayyaz
    I'm developing a game for Android devices and I have a script that solves the aspect-ratio problem for computer screens but not for my intended target platform. It looks perfect on computer, even when re-sizing the game screen, but not when running my game in landscape mode on mobile phones. This is my script using UnityEngine; using System.Collections; using System.Collections.Generic; public class reso : MonoBehaviour { void Update() { // set the desired aspect ratio (the values in this example are // hard-coded for 16:9, but you could make them into public // variables instead so you can set them at design time) float targetaspect = 16.0f / 9.0f; // determine the game window's current aspect ratio float windowaspect = (float)Screen.width / (float)Screen.height; // current viewport height should be scaled by this amount float scaleheight = windowaspect / targetaspect; // obtain camera component so we can modify its viewport Camera camera = GetComponent<Camera>(); // if scaled height is less than current height, add letterbox if (scaleheight < 1.0f && Screen.width <= 490 ) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } else // add pillarbox { float scalewidth = 1.0f / scaleheight; Rect rect = camera.rect; rect.width = scalewidth; rect.height = 1.0f; rect.x = (1.0f - scalewidth) / 2.0f; rect.y = 0; camera.rect = rect; } } } I figured that my problem occurs in this part of the script: if (scaleheight < 1.0f) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } Its look like this on my mobile phone (portrait): and on landscape mode:

  • Is it wrong to tell mobile users to view a site on their computer?

    - by betamax
    I am creating a web application that doesn't work correctly on mobile. I don't want to make it work on mobile because I would rather mobile users have a fully integrated experience and not have to use the web version. This mobile version will be released at a later date based on reaction to the initial web-based version. So, my question is: Is it wrong to not allow mobile users to use the site and instead show them some sort of splash screen telling them to come back to the site on a computer?

  • I'm graduating with a Computer Science degree but I don't feel like I know how to program.

    - by wp123
    I'm graduating with a Computer Science degree but I see websites like Stack Overflow and search engines like Google and don't know where I'd even begin to write something like that. During one summer I did have the opportunity to work as a iPhone developer, but I felt like I was mostly gluing together libraries that other people had written with little understanding of the mechanics happening beneath the hood. I'm trying to improve my knowledge by studying algorithms, but it is a long and painful process. I find algorithms difficult and at the rate I am learning a decade will have passed before I will master the material in the book. Given my current situation, I've spent a month looking for work but my skills (C, Python, Objective-C) are relatively shallow and are not so desirable in the local market, where C#, Java, and web development are much higher in demand. That is not to say that C and Python opportunities do not exist but they tend to demand 3+ years of experience I do not have. My GPA is OK (3.0) but it's not high enough to apply to the large companies like IBM or return for graduate studies. Basically I'm graduating with a Computer Science degree but I don't feel like I've learned how to program. I thought that joining a company and programming full-time would give me a chance to develop my skills and learn from those more experienced than myself, but I'm struggling to find work and am starting to get really frustrated. I am going to cast my net wider and look beyond the city I've grown up in, but what have other people in similar situation tried to do? I've worked hard but don't have the confidence to go out on my own and write my own app. (That is, become an indie developer in the iPhone app market.) If nothing turns up I will need to consider upgrading and learning more popular skills or try something marginally related like IT, but given all the effort I've put in that feels like copping out. EDIT: Thank you for all the advice. I think I was premature because of unrealistic expectations but the comments have given me a dose of reality. I will persevere and continue to code. I have a project in mind, although well beyond my current capabilities it will challenge me to hone my craft and prove my worth to myself (and potential employers). Had I known there was a career overflow I would have posted there instead. Thanks again!

  • Do I have to do anything for file ACLs to work both before and after I reformat a computer?

    - by Zian Choy
    Let's say that I have a computer running Windows Vista with 2 users: Alice and Bob. Alice is the admin and Bob is a normal user. They each have files in their respective My Documents folders and Bob is not allowed to view Alice's files and Alice has to jump through a UAC elevation to view Bob's. If Alice copies all the files on the computer to an external NTFS-formatted hard drive with the following 2 commands: robocopy "E:\Bob's Files" "C:\Users\Bob\My Documents" /MIR robocopy "E:\Alice's Files" "C:\Users\Alice\My Documents" /MIR And then reformats the hard drive, installs a fresh copy of Windows, and creates 2 users named Alice and Bob on the computer, then will everything in the first paragraph be true after Alice copies the files back onto the internal hard drive? Assume that when the files are copied back over, she logs in as Bob and then copies Bob's files and likewise with her own files. Possibly relevant: Alice and Bob also have passwords on their user accounts and they create new passwords after the computer is reformatted. The main post has been tweaked slightly to make the question clearer. Answers that predate April 2011 are referring to an earlier version of this post.

  • File sharing for small, distributed, non-technical, non-profit organization?

    - by mnmldave
    Problem: I've started volunteering for a small non-profit with fewer than five non-technical Windows users who need to share 20-30GB of files (Office documents, images, PDFs, etc.) amongst themselves online. Background: The users are accustomed to a Windows network share on a machine that backed up their data locally. An on-site "disaster" has forced them to work from their homes for awhile and to re-evaluate their file sharing needs (office was located in an old building with obvious electrical issues, etc.). Access to time from volunteers with IT experience seems to be difficult. Demonstrably minimizing energy consumption is a nice-to-have. I'm currently considering Jungle Disk (a Desktop account shared amongst the handful of employees since their TOS and my inquiries to their helpdesk seem to indicate this is permissible). It appears easy-to-use, inexpensive, secure, has backup functionality, and can scale to accomodate more data when needed. I've not used it myself though (have only used Dropbox for personal use) and systems isn't my area of expertise, so am worried I might be jumping on a bandwagon. That said, any suggestions, thoughts or similar experiences would be really appreciated.

  • NAT ports - how do they work?

    - by Davidoper
    I have the following network schema: Computer A: three nics: NIC 1 (eth0): dhcp, public internet NIC 2 (eth1): static 192.168.1.1, gateway for Computer B NIC 3 (eth2): static 192.168.2.1, gateway for Computer C Computer B: static 192.168.1.2, using gateway 192.168.1.1 (NIC 2). Computer C: static 192.168.2.2, using gateway 192.168.2.1 (NIC 3). So I applied this to get NAT working: iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE Every computer can connect to the internet now. I have been applying rules to the main computer (Computer A), like dropping connections to some ports, e.g ssh: iptables -A INPUT -p tcp --dport 22 -j DROP But for instance, now I would like only allow connections for ports 20,21,22,53 and 80 in Computer C, and ignore the outside traffic if it's not related to those ports. The allowed connections should be FROM Computer C to outside, but not from outside to Computer C (I mean - Computer C is not hosting any HTTP or SSH, but it is going to use them as a client). I guess this sould be done like this: iptables -A OUTPUT -i eth2 -o eth0 -p tcp --dport 21 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A INPUT -i eth2 -o eth0 -p tcp --sport 21 -m state --state ESTABLISHED -j ACCEPT The last rule (dropping any other traffic different from those) is at the end of the configuration, so -A should be working correctly. The thing is... it is not working. If I put the last rule like this: iptables -A FORWARD -i eth2 -o eth0 -j DROP It just drops everything and, for instance, port 21 (previously opened as you can see above) is not either working. Can you tell me what could I have done wrong? I have been struggling with this problem for some time and I am unable to solve it. Thanks!
