D-Link DIR-615 MAC Address Entered is Invalid

December 23rd, 2010 Alex Posted in hardware, internet Comments Off

I was trying to do a DHCP reservation but D-Link’s DIR-615 wouldn’t accept my phone’s MAC address because it didn’t start with “00″. Although the firmware was fixed since version 3.11NA (download update), here is what I did to work around this problem:

  1. Using Firebug in Firefox, set a break-point at line 420 in file public.js
  2. Edit temp_mac’s array value at position 0 from “fc” to “00″ (“fc” or anything else)
  3. Continue execution of script

What do I look for in a monitor? : hardware

November 1st, 2010 Alex Posted in electronics, hardware Comments Off

From my experience, anything over 1000:1 for contrast ratio is marketing speak. over 1000:1 is great. Anything under a 5msGTG is fine for movies. 3msGTG is fine for gaming. This one is 2msGTG. Anything over 250 cd/m2 is great for brightness. This monitor has a 400 cd/m2. Resolution is perfect. 1900×1080 allows you to watch 1080p movies with no problem. Viewing angle is actually where you want to start to be for multiple people watching. a 170H allows for people to be as much as 85 degrees off the center, but you still can not see it from the sides, nor from too low or standing up looking down on it with the 160V. For a model this large, the dot pitch is ok, but if you are <3ft in front of it, you would look for something closer to a .260. this measures the distance from one red pixel to another red pixel.The one thing I look for that this does not have is the LED backlighting. It seems to be hard to get monitors this large with it and at least 1900×1080, but it is possible.The other things you have to have is HDCP support if you ever want to legally watch a HD movie on it, and a comprehensive warranty. Bear in mind that for some companies, a few dead pixels are enough to trigger a warranty, while some require quite a lot.The final thing to bear in mind is what you are going to be using the monitor for. For gaming and movies, a TN twisted nematic panel is ideal because of the low response times. If you are using it for spreadsheet and database work, you are looking for a VA vertical alignment panel. These include MVA multi-domain and PVA patterned, which may also come in higher-contrast AMVA advanced MVA and S-PVA super PVA versions. All these VA types reduce eyestrain.If you do professional photo editing or video editing, a monitor with an in-plane switching IPS panel is what you want. These monitors have the best LCD color accuracy plus wide viewing angles. Super-IPS S-IPS, premium-IPS P-IPS and horizontal-IPS H-IPS are the best-quality IPS panels. Eventually, we will have OLED displays that will rival the LCD for size and price, but this is where we are now.I generally try to stick with Samsung, LG, BenQ, Dell, Some HP monitors, Apple, and Viewsonic. I did have a 27.5 Hanns·G I got for real cheap, but I prefer my 2x 23″ LG W2486L s.The Hanns·G HZ281HPB was a pretty good monitor, but I like multiple monitors for the way I work better than one large monitor. It was less than $350, and it is less than $300 now. ViewSonic also makes the VA2702w for less than the Hanns·G, and their warranty is generally better, as is their customer service, however, dealing with Newegg, you should not have to deal with either, because if it is not DOA, it should be fine.

    My Computer

    January 14th, 2007 Alex Posted in hardware Comments Off

    My Computer

    • Motherboard: Asus M2N4
      • Supports AMD socket AM2 (Athlon 64 FX / Athlon 64 X2 / Athlon 64 / Sempron
      • SLI Support (Takes advantage of the increased bandwidth of the PCI Express bus architecture and allows two video cards to efficiently work together to deliver nearly 2X performance!)
      • SATA RAID 0, RAID 1, RAID 0+1, RAID 5
    • Video Card: NVidia Quadro FX1400 PCI-E 128MB (SLI compatible)
    • CPU: AMD X2 4200+ (Retail version to get AMD’s approved fan and heatsink to get a longer warranty)
    • Case: Antec P180
    • Power Supply: ANTEC TP3-650 (650 Watts SLI compatible)
    • SATA Harddrive: Western Digital Raptor 74GB with 16MB buffer size (Very fast harddrive but a little noisy)
    • RAM: 2 GB RAM PC2-4200 DDR2 (Max 8GB)
    • Monitor: JW-199DPB 19″ Hanns-G LCD
    • Printer: All-In-One HP PSC1410 which is fully Linux compatible.

    The motherboard doesn’t come with Firewire (IEEE 1394) interface but the case has a front firewire port which would be useful if I ever add a PCI firewire adapter

    Possible upgrades:

    • More RAM
    • Second identical video card and use SLI (or a better card)
    • Another Raptor harddrive to use RAID capabilities
    • upgrade processor
