• Alternative software to Freedom and/or Anti-Social?

  - by mummey

  Freedom: http://macfreedom.com/ Anti-Social: http://anti-social.cc/ Simply put: Where can I find a alternative software to either-or/both these apps? Note: Part of the appeal of these apps is allowing the user to explicitly make it extra difficult to re-enable these services. Unplugging the network cable might seem to achieve the same results from an glance, but the added difficulty in re-enabling those services is what makes these apps valuable.

• Is implementing an interface defined in a subpackage an anti-pattern?

  - by Michael Kjörling

  Let's say I have the following: package me.my.pkg; public interface Something { /* ... couple of methods go here ... */ } and: package me.my; import me.my.pkg.Something; public class SomeClass implements Something { /* ... implementation of Something goes here ... */ /* ... some more method implementations go here too ... */ } That is, the class implementing an interface lives closer to the package hierarchy root than does the interface it implements but they both belong in the same package hierarchy. The reason for this in the particular case I have in mind is that there is a previously-existing package that groups functionality which the Something interface logically belongs to, and the logical (as in both "the one you'd expect" and "the one where it needs to go given the current architecture") implementation class exists previously and lives one level "up" from the logical placement of the interface. The implementing class does not logically belong anywhere under me.my.pkg. In my particular case, the class in question implements several interfaces, but that feels like it doesn't make any (or at least no significant) difference here. I can't decide if this is an acceptable pattern or not. Is it or is it not, and why?

• How can I safely close this window and forever avoid seeing similar pop-ups from Mackeeper Zeobit's malware and spyware?

  - by Michael Prescott

  The attached image shows a window that just popped up and the only button available is the OK button. I could Force quit Safari, but I've got several sites open right now and don't want to try and find my place again. Besides, I've seen similar hacks in the past and I'd like to learn how to handle them in a way better than just a brute force-quit. I've never heard of MacKeeper or Zeobit, so I opened Firefox and did a few searches while Safari is obviously still stuck, waiting for me to click the sneaky OK button in the dialog window. Anyhow, at least the first few pages of most search results contain lots of blabbering from questionable witnesses about how MacKeeper saved them from some malware or spyware. However, any company that is hacking the browser to maliciously install their product is itself the criminal and not providing a true security application. So, there are three questions here: How can I close this window? Can I do something to Safari to avoid these hacks in the future? (Just curious) Is MacKeeper or Zeobit somehow loading the search results so that no information about their application being malware or spyware is listed (I can't be the only person in the world that is offended by their tactics, even though it appears I am)?

• Question about malware-sites: How can I be in danger?

  - by juanmaflyer

  Hi people!! My english is horrible but i will do the best to be as accurate as posible. I have been reading here (in superuser) some questions about the necessity of antivirus software in Windows and some doubts arise. As far as i know (and imagine) virus software can only be harmful if I download any type of infected executable file and then I RUN IT. I mean that if i have the infected executable in my desktop but i leave it there for years without clicking it, I won't be in danger... My question is: How can i be in danger browsing the so called "malware pages or sites"??. If i am just browsing an "infected site" how could I be affected by a virus. In any moment the browser is asking me for the permission to download "something", so how could it be?? Although i don't give permission to the browser to download 'something' is data being downloaded to my computer?? Its some kind of cookie? I will ask in another way... What is the level of riskiness if i get inffected in a malware site compared with the level of an executable virus?? Thanks a lot!

• What are the most common SQL anti-patterns?

  - by le dorfier

  All of us who work with relational databases have learned (or are learning) that SQL is different. Eliciting the desired results, and doing so efficiently, involves a tedious process partly characterized by learning unfamiliar paradigms, and finding out that some of our most familiar programming patterns don't work here. What are the most common antipatterns you've seen (or your self committed), whether generic or product-specific, whether in SQL statements directly, or in the ways applications build and apply them?

• What are the most commonly used anti-patterns?

  - by Esteban Araya

  I'm just wondering what are some of the classic mistakes we all make. I think before working on writing good code, you must learn to recognize bad code... especially when it's YOUR code!

• Risking the exception anti-pattern.. with some modifications

  - by Sridhar Iyer

  Lets say that I have a library which runs 24x7 on certain machines. Even if the code is rock solid, a hardware fault can sooner or later trigger an exception. I would like to have some sort of failsafe in position for events like this. One approach would be to write wrapper functions that encapsulate each api a: returnCode=DEFAULT; try { returnCode=libraryAPI1(); } catch(...) { returnCode=BAD; } return returnCode; The caller of the library then restarts the whole thread, reinitializes the module if the returnCode is bad. Things CAN go horribly wrong. E.g. if the try block(or libraryAPI1()) had: func1(); char *x=malloc(1000); func2(); if func2() throws an exception, x will never be freed. On a similar vein, file corruption is a possible outcome. Could you please tell me what other things can possibly go wrong in this scenario?

• nVidia Settings: Overriding anti-aliasing causes delay

  - by Kalle Elmér

  I'm using Google Sketchup on ubuntu 12.04 with Wine 1.4. It works flawlessly out of the box, but anti-aliasing is causing some problems. I can override anti-aliasing settings using the nVidia X Server Settings utility, which results in a great-looking image. However, the view doesn't seem to update properly. It's a bit hard to explain, but if I do something (e.g. zooming) the changes won't appear in the view until I take another action. in other words, there seems to be a delay of one "action". Take this example. The mouse wheel is moved one notch to zoom in one step. Nothing happens. An object is selected by clicking. The new zoom is rendered but the selection box doesn't appear. An empty area is clicked. The selection box appears. Is there something that I can do to solve the problem? Could I force the GPU to redraw that view with a certain interval, or is there some other solution? I really like anti-aliasing, but it's hard to use when drawing stuff.

• Worthless Anti-Spam (What can we learn)

  - by smehaffie

  I recently can across a site that had a “anti-spam” field at the bottom of the entry from.  The first issue I had with it was that at 1280X800 you could not read the value you were suppose to enter (see below).  You tell me, should you enter div, dlv, piv, or plv. But even worse than not being readable at high resolutions is the fact that the programmer who coded it really did not understand what this was used for.  An anti-spam (aka: catpcha) entry field should not be able to be read by looking at the HTML DOM object (so entry of value cannot be scripted).  In this case the value is simply a disabled text input filed that has the value you need to type.  So a hacker would simply need to search for text input field named “spam2” and then they could flood the site with spam. 1: <td> 2: <label> 3: <input name="spam1" type="text" class="small" id="spam1" size="6" maxlength="3" /> 4: <input name="spam2" type="text" class="small" id="spam2" value="plv" 5: disabled="disabled" size="6" maxlength="3" /> 6: * <span class="small">- Anti-SPAM key - please enter matching value</span> 7: </label> 8: </td>   There are some things to learn from this example: 1) Always make sure you understand why you are coding a feature/function for any program you write.  Just following the requirements without realizing the “why” will sooner or later come back to bite you.  I think the above example appears to be an example of this. 2) Always check how the screen appears in different resolutions.  In this case it was pretty much unreadable in 1280x800, but you could read it in 800X600 (but most people I know do not have their resolution set that low).  Lucky for me I could “View Source” and get the value I needed to enter.

• Hijack.StartMenu Malwarebytes Anti-Malware is a false positive?

  - by Senseful

  I just ran the Malwarebytes Anti-Malware quick scan for the first time and it found: Registry Data Items Infected: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Start_ShowSearch (Hijack.StartMenu) - Bad: (0) Good: (1) - No action taken. I just wanted to double check (and provide a top Google result for people in the future that might have the same issue) that this was a false positive and can be safely right-click ignored.

• What sites/publications are good for staying current on security and malware trends?

  - by Holocryptic

  In my ever expanding quest for knowledge, I'm at the point where I feel like I need to be more up to date with the current security trends, as well as malware and such that are in the wild. I'd like to be able to say, "I've heard of that and the fix is...." versus, "Oh, yeah, I had that eat up half my network before I contained it...." What sites and publications are good for keeping up with these things?
