  • How dependecy injection increases coupling?

    - by B?????
    Reading wiki page on Dependency injection, the disadvantages section tells this : Dependency injection increases coupling by requiring the user of a subsystem to provide for the needs of that subsystem. with a link to an article against DI. What DI does is that it makes a class use the interface instead of the concrete implementation. That should be decreased coupling, no? So, what am I missing? How is dependency injection increasing coupling between classes?

  • Atheros AR928X wireless connection makes neighbourhood machine drop off line

    - by funicorn
    I have an Acer laptop with Atheros AR928X wireless card installed, supported by ath9k driver in the linux kernel. There are other 5 computers sharing wireless connection via a TPLink 150Mbit/s wireless router. At first I found the network is a little bit slower than it's in Windows7, which I accepted as it should be. However a very strange thing is, each time I connected to the router and downloaded stuff for a while, one of the computers running Windows7 in my local network dropped off from the router. And if I run my laptop under Windows7, everything is fine. What's even stranger is although the network becomes slower, only the certain computer drops and totally freezes in connection with the router. I'm not willing to conclude it's due to the unhealthy connection from my laptop to the router, however we have confirmed this for more than one times and there is no problem with the network when I'm running WIndows7. I'm extremely confused about what's going on. As a Linux user running Ubuntu over 5 years, I am awared that wireless driver in Linux is badly notorious of lack of stability and slow speed. But is it so bad that the unhealthy wireless connection can do damage to another computer in the same local network? I do see a lot of "Tx excessive retries" in iwconfig output. But how exactly does this happen ? Thanks for your help. I guess I have to use this answer box to show the outputs $ sudo iwconfig wlan0 IEEE 802.11bgn ESSID:"TP-LINK111" Mode:Managed Frequency:2.427 GHz Access Point: E0:05:C5:E8:A9:92 Bit Rate=121.5 Mb/s Tx-Power=16 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=47/70 Signal level=-63 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:2 Invalid misc:23 Missed beacon:0 To show what's wrong with the wireless connection, I ran iwconfig again within 3 minutes, during which time I hardly did anything and the network was not much busy than being nearly idle $ sudo iwconfig wlan0 IEEE 802.11bgn ESSID:"TP-LINK111" Mode:Managed Frequency:2.427 GHz Access Point: E0:05:C5:E8:A9:92 Bit Rate=121.5 Mb/s Tx-Power=16 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=48/70 Signal level=-62 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:9 Invalid misc:28 Missed beacon:0 You can see Tx excessive retires and Invalid misc increase very quickly. $ sudo iwlist wlan0 modu wlan0 unknown modulation information. $ sudo iwlist wlan0 channel wlan0 13 channels in total; available frequencies : Channel 01 : 2.412 GHz Channel 02 : 2.417 GHz Channel 03 : 2.422 GHz Channel 04 : 2.427 GHz Channel 05 : 2.432 GHz Channel 06 : 2.437 GHz Channel 07 : 2.442 GHz Channel 08 : 2.447 GHz Channel 09 : 2.452 GHz Channel 10 : 2.457 GHz Channel 11 : 2.462 GHz Channel 12 : 2.467 GHz Channel 13 : 2.472 GHz Current Frequency:2.427 GHz (Channel 4)

  • Can I instruct the browser not to look for a favicon?

    - by Peter Boughton
    I have a website that doesn't have/need a favicon. Is there a way to instruct the browser not to waste a request looking for /favicon.ico ? I don't mean filtering logs, but something client-side, like this: <link rel="shortcut icon" href="about:blank" /> That appears to work, but I'm not in a position to do comprehensive tests, (and search engines are being unhelpful). Can anyone confirm if this is a valid method, or provide a suitable alternative?

    I am looking for an architecture diagram of a computer virus. Does anyone have a link to a good example? Edit Looks like I am getting hammered with downvotes. I agree that there is no single architecture for a virus. But somethings must be included for a program to be a virus.

  • Conventional Parallel Inserts do Exist in Oracle 11

    - by jean-pierre.dijcks
    Had an interesting chat with Greg about said topic and searching showed the following link to discuss this topic in some detail (no reason for me to repeat this). insert /*+ noappend parallel(t1) */ into t1 select /*+ parallel(t2) */ * from t2 generates a load table conventional and does give you a parallel insert without doing a direct path insert. As this is missing from the official documentation it is probably something few people actually know existed, so kudos to Randolf Geist.

  • Tracking based on URL referral?

    - by jeremycollins
    Hi, Users on my site are given unique URL's for me to then track how many people they have referred to my site. ie: http://www.example.com/FQ3DL (FQ3DL being the unique code/url) The first thing I'd like to do is when a user goes to that link, it displays the homepage http://www.example.com/ rather than a 404 error The second thing is, how would I track how many people have visited that URL? Only through Google analytics or is there another way to manage it? Thanks!
