  • Clicking on clues and other objects in a 2D cluedo like game

    - by Anearion
    I'm a java/android programmer, but I don't have any experience in game programming, I'm already reading proper books, like "Pro Android Games", but my concerns are more about the ideas behind game programming than the techniques themselves. I'm working on a 2D game, something like Cluedo to let you understand the genre. I would like to know how should I act with the "scenes", for example, a room with a desk, TV, windows and a lamp. I need to make some items tappable and others not. Is it common to use one image (invisible to the user) with every different item a different color, then call the getColor() method on the image? Or use one image as background, and separate images for all the items? If the latter, how can I set the positioning? and should I use imageView or imageButton? I'm sorry if those are really low quality questions, but as "outsider" ( I'm 23 and still finishing my university ) it's pretty hard learn alone.

  • What Counts for A DBA - Logic

    - by drsql
    "There are 10 kinds of people in the world. Those who will always wonder why there are only two items in my list and those who will figured it out the first time they saw this very old joke."  Those readers who will give up immediately and get frustrated with me for not explaining it to them are not likely going to be great technical professionals of any sort, much less a programmer or administrator who will be constantly dealing with the common failures that make up a DBA's day.  Many of these people will stare at this like a dog staring at a traffic signal and still have no more idea of how to decipher the riddle. Without explanation they will give up, call the joke "stupid" and, feeling quite superior, walk away indignantly to their job likely flipping patties of meat-by-product. As a data professional or any programmer who has strayed  to this very data-oriented blog, you would, if you are worth your weight in air, either have recognized immediately what was going on, or felt a bit ignorant.  Your friends are chuckling over the joke, but why is it funny? Unfortunately you left your smartphone at home on the dresser because you were up late last night programming and were running late to work (again), so you will either have to fake a laugh or figure it out.  Digging through the joke, you figure out that the word "two" is the most important part, since initially the joke mentioned 10. Hmm, why did they spell out two, but not ten? Maybe 10 could be interpreted a different way?  As a DBA, this sort of logic comes into play every day, and sometimes it doesn't involve nerdy riddles or Star Wars folklore.  When you turn on your computer and get the dreaded blue screen of death, you don't immediately cry to the help desk and sit on your thumbs and whine about not being able to work. Do that and your co-workers will question your nerd-hood; I know I certainly would. You figure out the problem, and when you have it narrowed down, you call the help desk and tell them what the problem is, usually having to explain that yes, you did in fact try to reboot before calling.  Of course, sometimes humility does come in to play when you reach the end of your abilities, but the ‘end of abilities’ is not something any of us recognize readily. It is handy to have the ability to use logic to solve uncommon problems: It becomes especially useful when you are trying to solve a data-related problem such as a query performance issue, and the way that you approach things will tell your coworkers a great deal about your abilities.  The novice is likely to immediately take the approach of  trying to add more indexes or blaming the hardware. As you become more and more experienced, it becomes increasingly obvious that performance issues are a very complex topic. A query may be slow for a myriad of reasons, from concurrency issues, a poor query plan because of a parameter value (like parameter sniffing,) poor coding standards, or just because it is a complex query that is going to be slow sometimes. Some queries that you will deal with may have twenty joins and hundreds of search criteria, and it can take a lot of thought to determine what is going on.  You can usually figure out the problem to almost any query by using basic knowledge of how joins and queries work, together with the help of such things as the query plan, profiler or monitoring tools.  It is not unlikely that it can take a full day’s work to understand some queries, breaking them down into smaller queries to find a very tiny problem. Not every time will you actually find the problem, and it is part of the process to occasionally admit that the problem is random, and everything works fine now.  Sometimes, it is necessary to realize that a problem is outside of your current knowledge, and admit temporary defeat: You can, at least, narrow down the source of the problem by looking logically at all of the possible solutions. By doing this, you can satisfy your curiosity and learn more about what the actual problem was. For example, in the joke, had you never been exposed to the concept of binary numbers, there is no way you could have known that binary - 10 = decimal - 2, but you could have logically come to the conclusion that 10 must not mean ten in the context of the joke, and at that point you are that much closer to getting the joke and at least won't feel so ignorant.

  • How to simulate a USB plug?

    - by Nicolas Delvaux
    I have an app that implements some automations when an USB key is plugged. While developing, I have to test it in a specific environment (derivative from Debian Squeeze). The app subscribe to HAL events via DBUS. The problem is: my desk is on the third floor while my test machines are in the basement. I would really like to have a way to simulate a USB plug. usbip does not work on Ubuntu. I can't manage to use the g_mass_storage module on Ubuntu (I lack the dummy_hcd module) and in Debian. Maybe it is possible to simulate a dbus call? My work station is on Ubuntu 12.04.

  • Does a person's day-to-day neatness (outside of programming) relate to quality and organization in programming?

    - by jiceo
    Before anyone jumps into any conclusion, I had a discussion with a friend (who's not a programmer at all) about the relationship between a person's neatness habit and the degree of neatness generally shown in works by the same person. This led me to think about this situation: Let's imagine you knew a programmer whose house was very messy. This person's lifestyle is messy by nature. On his desk there are books, papers, STUFF, piled everywhere including on the floor, mixed with dirty clothing, with no obvious organization at all. If you asked him to find a book he hasn't touched for at least a week from the cluster of chaos, he would take at least an hour to do so. How likely is it that he will produce very clean, consistent, and organized code that other people can use? Are there CS legends that are/were notoriously messy in day-to-day habits?

  • How much time do you need in between large projects?

    - by Mattio
    You've launched a large project at work, something that's been in progress and taken up large chunks of your life for more than 6 months. The post-launch triage is over. Tech support isn't calling you every hour because they don't know how to troubleshoot an issue. Your hours drop from 60+/wk to whatever is normal in your organization (which is hopefully less than 60+!). How much time do you (or your team) need before the next large project begins? I was asked this question at work and I think the ideal minimum is two weeks -- one week to clear your desk and inbox + one week to clear your head and remember what it's like to have a life outside of work. I'd frankly acknowledge that just being asked this question is a huge boon to work/life balance. But I do think it's possible to go too long in between.

    - by Toscano
    In upgrading 12.04 to 12.10 via system upgrade when the system rebooted all I got was my desk-top without any command icons. Now all my files are locked into 12.10 and no way to retrieve them. I finally reinstalled 12.04 in a new partition but I don't have the knowledge on how to access 12.10 from it. Being a newbie with Linux I feel like I have all thumbs. I'd like to correct 12.10 but have to idea on what the problem is or how to access it. HELP!!!

  • What is the best keyboard/mouse for ergonomics or to prevent wrist pain?

    - by Steve Duitsman
    I have had pain in my wrists in the past, and as someone who types all day, I was wondering what are some keyboards or mice that have helped for this sort of pain. Update: Many answers have recommended examining chairs/desks for ergonomics. As someone who isn't able to work from home and therefore doesn't have a lot of control over this; is ordering my own chair/desk (whether my employer or I purchase it) a solution that's really realistic?

  • Highlight overlapping text in JQuery

    - by Jasie
    I've got this plain HTML: "Many things are in my room: a bed, a desk, and a computer." And these phrases: "things are" "are in my room" "room: a bed" In JQuery, is there some way to loop through the phrase list, and highlight the phrases as they appear in the text, and have the overlap delineated by color, or border, etc? I know there are simple highlighters but that won't do the trick. Maybe something with overlaying opacities? Thanks!
