  • 2016: What tech does your xtal ball show you buying/upgrading-to ?
    E Edwin Smith

    Now that my significant other has a nice new laptop with the latest high-speed WiFi I plan to upgrade the WiFi in the house and add ipV6 capability at the same time. Eventually AT&T will deploy ipV6 locally. Someday they might add fiber to the home if Google doesn't beat them to it.

    I had a KIM-1 with 4 KB memory. No disk, no tape. Just a hex keypad and a 6 X 7 segment display. After an hour of hand keying in the program you could play Hunt the Wumpus!

    What you need is a pair of Linksys WRT54GL's and DD-WRT firmware. I'm doing similar from the back of my apartment to the front as both a range extender and a bridge. Works great but it's not 'N'. Edwin

  • Backup/Sync tool suggestions?
    E Edwin Smith

    Yes. WHS is cool though I haven't a lot of experience with it. I run a consulting business so I use the same practices I recommend to my clients. I store nothing of any importance on any PC or laptop. Everything is on the server. This way if a laptop is lost/stolen there is little if any data of value to the "new owner" :-) or loss to me other than the hardware itself. All of the redundancy is in the server and it's backups. I'm not at all suggesting that my way is best for all but it makes it simpler for my clients to maintain control of their data which is VERY important for Doctors, Lawyers and accountants. (HIPAA & Sarbanes/Oxley) But I agree that for a family with many PC/Laptops that WHS is a good option. The unfortunate thing is I don't market to non-businesses. I do have an old server in the closet that I plan to put WHS on and try selling at the next yard sale. Edwin

  • Backup/Sync tool suggestions?
    E Edwin Smith

    I use Small Business Server myself. I have a double redundant RAID and I backup weekly to a pair of SATA drives in a plug in cage. You could always use Xcopy with a scheduled job to backup new or modified files to a networked PC on your LAN. The Schedule could be as often as you feel comfortable.

  • The Warm Glow of the Computer
    E Edwin Smith

    At my job I did some very limited assembly coding on an IBM-360. in later jobs I worked with Microdata and PDP mini's. I played my first "Adventure game on a Microdata mini with 16KB of core memory. One of the hardware engineers at still another job gave me a KIM-1. It was a 6502 based SBC with a hex keypad and a 6 digit 7 segment LED display. I spent hours keying in "Hunt the Wumpus" on it. I soon became a hardware designer myself and I did some coding for 2901 state engines. Later I made my own state engines with PLD's. What fun! Later a group of us guys formed a small company to design and manufacture an interface to connect 10 MB 14 inch hard disk drives to TRS-80's, Apple II's and S-100 computers. This was just before disk technology evolved into the sealed IDE hard disk drives which made our product obsolete. Now I'm doing this. Edwin

  • Programming's Foul Language
    E Edwin Smith

    Since I barely knew Dartmouth Basic when I started designing state machines for hardware controllers i didn't know there was anything like "goto" or "gosub". In all of the microcontrollers I've ever coded all we had were JMP, CALL, and sometimes SKIP for controlling program flow. Goto and Gosub were all higher level code which had to be interpreted or compiled into code the CPU could understand. I've also made state machines with NO ALU at all and one in particular out of PLD's that had NO compiler at all. I had to design the program flow by burning fuses in the PLD. No memory, no eproms, no disks, no keyboard and no display. Also, mine is bigger than yours. :-) Edwin

That a framework can be accused simultaneously of being too complex and too dumbed down shows that it truly is a damned-if-you-do-damned-if-you-don't kind of situation for MS.

    IMHO the problem with dumbing it down is that it makes it much more difficult to figure out when something doesn't work like you want. I.E. it's hard to figure out why it won't start if you can't get the hood up. Edwin

    Others recommend Expression Blend as a solution but AFAIK it is not a free option.

    I am a Microsoft Action Pack Subscriber. By taking a simple open-book exam I was able to get the Microsoft Expression Suite along with VS2K8 Std at no additional cost. Unfortunately I haven't had much use for it yet but I thought I would pass along the (almost) free option. The Action Pack costs me $299/yr and gets me about 8 times more Microsoft software than I can use. (No. I am not a shill for Microsoft.) Edwin

  • Book covering basic physics/electronics relevant to computer science?
    E Edwin Smith

    I would beg to differ! An FET (the T means transistor) is essentially a triode and functions much the same as a vacuum tube triode although at a much lower voltage. the only difference between an NPN transistor and a vacuum tube triode is that the transistor requires a positive (+) to turn it on and a vacuum tube triode (and an FET) requires a negative (-) bias to turn it off. Otherwise both an NPN transistor and a vacuum tube triode are exactly analogous. The emitter is analogous to the cathode, the base is analogous to the grid and the collector is analogous to the plate. With an FET the source is analogous to the cathode (although there are both N-channel and P-channel FETs which have the opposite polarities) the gate is analogous to the grid and the drain is analogous to the plate. All of the mentioned devices have three connections which function in almost exactly the same way and intrinsically do so at the quantum level. Besides, intrinsically, triode means three electrodes. Both transistors and vacuum tubes have both Newtonian and quantum characteristics. However for the most part we use the smooth curves of the "real" world to describe their characteristics while any transfer of energy happens in distinct quanta. Both transistor and vacuum tube noise are quantum phenomena but they are usually expressed as DB in the analog world and mostly irrelevant in the digital world. All energy converted in a resistor can be expressed in the simple formula E=IR where E is volts, I is Amperes, and R is Ohms. Algebraically it is a linear function but at the quantum level Schrodinger's cat has the final say. You might just as well have said that everything is intrinsically quantum mechanical which adds nothing to the conversation. Diodes were discovered before quantum mechanics was even a theory and so were electricity and x-rays. There was great controversy as to whether light was composed of particles or waves because it has the characteristics of both. To learn basic electronics and Newtonian physics does not at all require any knowledge of quantum mechanics at all. I learned about donors and holes in semiconductors and electrons, neutrons, and protons in my electronics class and also noise but it really wasn't necessary to know to do design work with either transistors or vacuum tubes. In fact it was many years later that I even heard about quantum mechanics. It is commendable that somebody is curious enough to want to know electronics and physics. In fact a basic grounding in Physics should be ma

  • Debug code won't die gracefully.
    E Edwin Smith

    I have a database app which runs OK so far except for when I close the form by clicking the X the myprogram.exe process is left still running. Subsequent debug runs fail to start because the myprogram.exe file is still open and can't be updated by the debugger. Even if I quit VS2005 completely the myprogram.exe process is still running and has to be killed manually in Task Manager. This program utilizes a Pervasive v.9 ODBC driver to an existing database on a server. I used the Querry builder and drag/drop to build the form which uses a DataGridView control and several label controls to display the rest of the row that is selected in the DataGridView control. Is there something I should be doing to properly close everything down in re: the ODBC driver? Thanks Edwin

  • How do I Index into a grid view while typing string?
    E Edwin Smith

    Hi: This is my first time posting to this board and I'm relatively new to programming with Visual Studio 2005 but I'm not new to programming in general. I have a database app which uses a DataGridView control with 4 columns displayed. This is constructed with drag and drop from Data Sources and works well. I would like to provide a textBox control that indexes into the "Name" column of the Grid View as a string is typed in the box. I.E. if I type a "V" the grid goes to the first name which starts with V then as I type the rest of the name it goes to the first name that starts with the letters in the textbox. The user can continue typing until he types the entire name or sees the name he wants and selects it with the mouse. Is there a control to do this? Thanks Edwin
