  huh

So if I give away another authors work, it's piracy.

But if a large corporation gives away another authors work, it's a free promotional placement deal.

Freaking amazing what you can do with a good lawyer ain't it?

They basically got raped in an alley and then received a bill for their attacker's services.

Keep in mind that when you RAID, you're not addressing at sector or filesystem cluster sizes anymore - you're addressing RAID block sizes. So a 1-byte change change to a file on RAID-5 can end up pretttty expensive - multiple drives as well as large blocks per drive.


...sssSo, a 1 bite (file change) write automatically requires/results in (assuming 3 drives) a complete rewrite of both of the corresponding blocks? That does sound a bit pricey. But it does explain why the block size selection is so critically dependent on intended usage during setup.


But I guess you'd have a smart administrator that tries to match FS cluster size, RAID block size and, in the case of SSDs, erase-block sizes to something reasonable.

Hm... Any chance you could give an example on the first part before I commit to a yes or no on that??  cheesy

The price, performance, reliability trinity will be keeping SSDs out of my range for a while yet. I just can't justify paying top dollar for cutting edge performance that might grenade if ya look at it funny. Pretty much the same reason I never got into overclocking heavily.

It shouldn't be too hard to get the localized info from Local Machine. T-Clock does it for certain parts of the custom format string. I can send you that section of the code if it'll help.

[FYI - I am moving my PHP/MySQL self-teaching initiative to the "Programming School" board.]

I'm no expert, but I have slapped together a ton of PHP/MySQL stuff ... Let me know if you get stuck.

yeah but how often are you going to ever want to change that value -- personally i dont know why everyone wouldnt stick to 1 yr view.
Wow.  Don't assume that however you use it is how other people want it.

It's a fair question that frequently needs to be addressed (probably more often) in software design; can you do something vs. should you do something.

The button idea I'm not real keen on as I spent an insane amount of time trying to get the window to wrap cleanly around the calendar control in all configurations and OSs. But. If I can hook the window's system menu, It might be cool to have flexibility options there.

I have run into occasions where view switching would have been handy as I do seem to have a rather tenuous grasp of time. 12 month view takes up a lot of screen-estate especially if one just wants a quick what day is next Tuesday answer. I also like the 1 month view as it alleviates the need to remember what month it is (like I said tenuous grasp...).


I'll add further investigation of this to the T-Clock to-do list, but all I can promis is it won't be soon. Currently most of my (scant) free time is going into my Got Space? NANY project. ...Which is also currently stalled due to the level of 9-5 Office projects keeping me on the ragged edge of burnout.

It's not so much the actual read/write is it is the fact that every drive in the array spins up for every read/write - so there's more wear and tear on the drive mechanics rather than the disk platter's surface.

Okay, now we're getting somewhere (i think).


If you saved a file to a single drive, only it would spin up and be written to (along with the housekeeping of finding sufficient free clusters. On a three element RAID-5, three drives would be spun up to accomplish the same thing, plus need to write additional information (i.e. parity) above and beyond that contained in the actual file itself. That's three times the disk activity plus "parity tax" plus three times the heat generated over a single drive save operation.

Hm... three times the disk activity regarding spinning up three drives, ok. But three times the i/o I ain't buying (I'm thinking closer to 1.5). The scenario also assumes the drives weren't already spun up for some reason (do SCSI drives ever spin down?).

Energy consumption/heat issues I can see (kinda) but it makes me wonder how much extra is another HDD actually gonna cost in a year (filed under why I hate accountants Wink) $5?


So when you add in the MTBF for each of the three drives, you have a higher probability of a drive failing all other factors being equal.

Granted statistics isn't my thing ... But if the MTBF for a given drive is 3,000 hours, then for 3 drives it should still be 3,000 hrs. Or is this just the Murphy's Law More moving parts... argument? <-I'll buy that - as it appeals to my cynical side (hehe)).


And most arrays have more than three drives since that's the least cost effective RAID-5 configuration since you always sacrifice one drive to parity even if that drive doesn't exclusively hold the parity data.

Funny, I would consider 3 or a multiple thereof to be the best choice for RAID5. As regardless of how many drives you have you're going to sacrifice 33% of the total storage for parity info. Goes back to the less moving parts is better argument. Use a smaller number of larger drives. *Shrug* Having 3 drives just makes the 33% parity "overhead" more obvious, not higher.


Most times, the drives chosen for arrays are built to a higher quality standard than those normally deployed in PCs - so that may even up the failure occurrence rate up between server and non-server drives despite a higher utilization rate.

I understand where you're going here, but I can't help but think that the design of a Server/Enterprise class drive would sort of have to be predicated on the fact that it would not be getting very much sleep (e.g. spinning down) ... Know what I mean?

if you are looking at things that could be added -- i'd love to see a full year calendar.

1, 3, & 12 month views are available for the calendar via the Miscellaneous tab.

Why would you be running T-Clock elevated??

i ran TClock in the elevated state to see if that solved the problem of the calendar not appearing but it didn't. then i tried after disabling UAC, upon which the calendar appeared. i still don't know what to make of it. any suggestions?

Well... Much as I'd love to say something brilliant ... I'm stumped.

I tried running it elevated here, and nothing worked (calendar, context menu, etc.). Damn Peculiar That Are!

But it shouldn't (ever) require elevated/administrative rights to do anything (it was designed not to). Maybe try double checking the mouse click settings, and/or setting them to a different action so we can see which part of what is failing.

(Long Shot) If you check properties on the clock.exe and tclock.dll files, do either of them show an UnBlock button?
2962  Main Area and Open Discussion / Living Room / Re: Building a home server. Please help, DC! on: August 05, 2011, 10:13:08 AM
^ Um...actually the data chunks and parity info are distributed among all the drives in a RAID-5  array by the controller. There isn't a unique "parity drive" per se AFAIK.  smiley

Okay, I've spent a bit too much time spoon feeding end users and my brain is turning to mush (brightly colored hand puppet stuff...).


Never the less, the parity info is stagged between the drives. So if something is written to the array it will be striped between 2 of the drives, and a third drive will catch the parity info. for any given write operation. Which goes back to my original quandary ... Where is the extra per-disk write that would possibly cause it to prematurely fail?
A gets half
B gets half
C gets parity

All are on separate physical disks. So other than controller traffic (that's a given) I don't see where anything is really getting doubled-up...At the per disk level. The parity section of each disk isn't going to take any more or less of a hit than its corresponding data segments. So it's not like it's being subjected to exhaustive localized rewrites that are going to "burn-a-hole" in it.
2963  Main Area and Open Discussion / Living Room / Re: Building a home server. Please help, DC! on: August 05, 2011, 07:09:15 AM
Raid-5 (and other "big storage" schemes) would be silly on SSD until their storage capability goes massively up. The added writes of raid-5 is a real concern,

Okay, this has been bugging me. What added writes?? RAID5 is striping with parity...So 2 of the drives split the writes and each get half the file. Parity is written to drive 3 which is (in that config) its sole purpose for existing. What's extra? Traffic on the controller?

I'm not arguing the point, just trying to understand it.
2964  Other Software / Developer's Corner / Re: T-Clock 2010 (download) on: August 05, 2011, 06:58:55 AM
Thanks for the program however after looking I cannot figure out how to display the calendar.

i'm having the same problem as darkhelmet. double-clicking does nothing even though i run it on an 'elevated' status. however if i disable UAC, then the calendar appears.

 huh Why would you be running T-Clock elevated??

As long as the Left Button->Double Click action is set to Show Calendar on the Mouse Tab, it should just pop open the (T-Clock) calendar. I never have figured out how to hook the default Win 7 calendar yet - But I do revisit the idea from time to time.

Just keep an eye on the logfile size and do some periodic housekeeping. Because you'll be amazed how quickly some of those logs can grow depending on the level of activity and degree of detail they're collecting.

Large but fixed size circular log is usually the safest balance. Other wise you have an off day and the server shuts down with a can't log X error. Panic ensues... (hehe)

Granted it not quite as glamorous, but audit tracking for various events/access types is built into Windows. And the security logs are searchable and can be filtered to only show what you're after at the moment.

Dave deletes file X. Audit tracking can be configured to show that (and when etc). Then you can simply filter by Dave and quickly see what else they were up to.

I've always felt that a real-time backup, really isn't a backup at all. It's a second copy of what just happened.

Here at the office I have too much data on my workstation to run through the rest of the offices nightly backup. So I use the built-in Win 7 backup to do nightly backups to one on the servers temporary storage RAID volumes. I don't remember if Vista has the newer Win7 style backup options...But it's worth exploring if it does.

I haven't found that the security software I currently use "only serve to slow the machine down (typically to a crawl)."  Not at all.  My computer is delightfully fast and responsive.  And WinPatrol Plus is not on my machine "just to monitor System files."  I use it primarily for a variety of other functions; it happens to also offer the option of protecting the Internet HOSTS and key System files.  Again, I haven't noticed that selecting this option negatively affects the performance of my computer.

Okay, I was being a bit harsh with the broad brush ... But I'm sure you've seen the type of baby-sitter security suite infested machine I was eluding to. I just wasted 6 hours onsite today because of a client's machine that was a few generations past it's prime, that had a full suite of crippleware running at full blast on it. There is never a truly effective way of disabling these silly things ... So you're always stuck with it unless you're willing to eat the time to remove and reinstall it.

Fortunately for the client it was a contract job. Or the bill would have been close to the price of a decent new machine. I got home an hour late, and the job still ain't done. *Joy*...

Microsoft has a good introductory article that gives you what options are available for various levels of "collaborative" use of an Excel workbook. Link here. This is where I point my clients initially when the question comes up. Most are interested in the section that's headed: Allowing multiple users to edit a workbook simultaneously. Scroll down about midway to find it.

Cool ... Just sent that link to a client, Thanks!

This may be a very silly question, but it has to be asked smiley:
if I dont use a password (admin account) is it all a waste of time anyways?

Yes. But if you wish to avoid having to type in a password every time it boots, you can use the old control userpasswords2 trick to set it to auto-login with a default account.

Auto-Login to Windows 7

Just don't forget the password or you may get locked out if you lock the console with Win + L.

Real-time scanners & AV software only serve to slow the machine down (typically to a crawl). And in so doing can only catch what they (have signatures for) know about. Anything new that comes down the pike is a heuristics crap-shoot.

The only truly effective method (outside of common sense), is reduced permissions. Because the bugg will only have as much permission as you do. So if you don't have permission to break the machine... Neither. Does. The. Bugg.

You have an entire application running full time, grinding up CPU cycles, Just to monitor "System Files". System files that would be completely untouchable by a standard user account ... Which requires 0 CPU time.

The only "safe" trade-off for those that persist in doing day-to-day activities with administrative rights, is UAC. But it must be allowed to isolate itself from you, to be able to defend the machine effectively. Other wise if you're both sharing the same desktop/session it ends up being the same ineffectively silly light speed foot race to the kill switch that you have with AV software. Bugg comes in, slits the AV's throat, and sets up shop. I see this cycle repeated again and again.

Lady brought a laptop in today; on it she had a veritable laundry list of security applications, UAC set to the max, and 3 root kits. She lacks the most important common sense layer of security and tends to click on whatever gets her to where she wants to be the quickest...Because she is "Protected". By Elfin Magic I guess... *Sigh* ...Must be where the term Sheeple came from. smiley
