Ticket came in last Saturday, and I'm working on it now. It's an old 2006 iMac (the MA199LL/A) that refuses to boot. Booting in startup manager shows the disk, but from there it hangs on the spinning gear-thing. Booting from DVD doesn't seem to work, and while I can get into singleuser mode, fsck -fy returns an error 0xe0030005 (UNDEFINED). Running fsck -fy returns slightly different errors and I remember reading somewhere that repeatedly running fsck -fy until you get an "all clear" can fix issues. Apart from Singleuser mode I can't boot at all. My knowledge of mac stuff is basically whatever I get from googling random error codes and symptoms. Anyone have any better ideas?

Hard drive was on my list of concerns but I wanted to see if I could boot to a DVD. I have an install DVD in there and holding C while starting up does nothing different. This made me think it was an issue beyond just the hard drive but now that I'm thinking about it it's most likely the hard drive.

We have spare 1TB hard drives lying around. Guess this iMac's getting an upgrade!

Dumb thought: Why is a dead hard drive preventing the Mac from booting from DVD?

Create a bootable drive/USB key with either the latest version of OS X or whatever version was installed on the iMac and then boot from that. The iMac could have a bad DVD drive so booting from an external disk is your best bet. It's way faster than the install DVD and can be loaded up with troubleshooting programs.

Bad DVD drive could explain the behavior beforehand. Is it possible to make a bootable drive using OS X Tiger from a Windows machine?

Based on some quick googling I came across a program called TransMac: http://www.acutesystems.com/scrtm.htm

From the looks of this Super User thread (http://superuser.com/questions/383235/create-a-bootable-usb-drive-from-a-dmg-file-on-windows) you can do it using that program. Assuming the program lets you create a dmg from the install DVD of Tiger that you have or if you can track down a DMG of the latest version of OS X. It looks like it is able to but ymmv

Also this: http://pureinfotech.com/2014/12/05/make-bootable-usb-mac-os-x-windows/

Or get a cheap external DVD drive and try with that

My boss once claimed that W3C sued someone over trying to add code to the HTML standard without their permission or something. This is really bothering me because the statement itself is obviously full of poo poo but I think there's some kind of bizarre half-truth in that statement somewhere that's getting twisted into an outright lie. Did W3C sue anyone over something like this?

W3C publishes recommendations. You can't force anyone to follow a recommendation. W3C also isn't a business, they don't have commercial or political interests as an organization, rather they're formed by employees/volunteers from actual companies and organizations that have an interest in an interoperable and accessible https://www.

The main thing I can think of, your boss might be referring to, would be Microsoft being a member of the W3C and not implementing the HTML 4, XHTML and CSS 2 recommendations according to spec, making IE 4, 5, 5.5 and 6 universally loathed by developers. That's mostly just a question of double standard.

See, that's what I thought. My boss unfortunately has a lot of cargo cult type knowledge where he's tried to figure stuff out on his own based on bits and pieces he's picked up and it's assembled into something that doesn't at all resemble reality.

One time he insisted to me that there are eight governing bodies of the Internet. I asked him to name some, so he googles "governing bodies of the Internet," finds an NPR article in the results, points to it, and says "NPR, that's one."

Well dude, I can show you right now that your system is completely incapable of using more than 4GB of RAM at the moment. No matter what we do, no more than that is used.

Maybe this bit of information led the guy to believe that Server 2003 32-bit supports 64 GB of RAM with PAE on, when in fact the version being used isn't enterprise and therefore doesn't support it.

Oh it is enterprise. But even if PAE is enabled, his system won't use more than 4gb.

The problem is that he's running out of memory. This server is running exchange, plus a small MySQL server, and is the domain controller to boot.

It chugs and halts along. When he tries to add a backup to the mix, the whole house of cards crumbles.

This, of course, means that it's our backup program causing the issue.

He just refuses to believe that the system isn't using the available memory despite me showing him it's only ever using 4gb in like four ways.

Isn't PAE meant to allow you to use more than 4gb? Like, that's the purpose. I don't know really anything about PAE, is it some sort of paging thing where the machine can only access 4 gigabytes of memory at a time?

In practice PAE tends to allow the OS to map various programs' own memory spaces all over a much larger than 4 GB address space, but the programs are still usually bound by 32 bit limits. PAE's primary benefit is making it so that 32 bit machines don't have as much of their RAM address space eaten up by having to map in the video memory etc. So if, for example, exchange is running out RAM due to handling too many things, it's running out of its process address space and thus can't use more than 4 GB of the system's 48 GB of RAM at absolute best, in reality probably a lot less.

On 32 bit Windows Server 2003, you can only use more than 4 GB of RAM at all with enterprise which supports up to 64 GB, but even if they had that if the server's not running a whole bunch of processes it'll never get close to using the 48 GB of RAM installed, unless they were intentionally using a RAM drive to eat up some of it.

Slanderer posted:

The 4gb limit came from a 32 bit architecture limits the memory address space. Processors and chipsets that support PAE have additional address lines, which allows a memory space of 2^36 bytes instead of 2^32. If the OS kernel supports PAE, it will map multiple page tables to the physical memory. I don't believe this changes the limitation on the size of the virtual address space an individual process can use, though, so you either need to use tricks to get a process to use more memory, or just have multiple processes.

PAE is also related to the 3GB barrier, which I vaguely remember but don't have time to refresh my memory on just right now: I think maybe PAE brought the actual memory limit of Windows XP (for instance) from 3gb to 4gb (but no more than that). https://en.wikipedia.org/wiki/3_GB_barrier
Alright, that makes sense. I imagine the kind of software that's being run on a Windows Server 2003 machine with 48gb of ram isn't large address aware to begin with so none of the apps are going above 2gb per app anyway.

I didn't quite phrase it that bluntly, but the whole reason I went in with a "I've got an offer" line was explicitly because I didn't want to burn bridges. I didn't really expect that they would be able or willing to make a legitimate counter-offer (which was a bit of a gamble), but did want to let them know it wasn't anything personal (even though it kind of was).

For the record, this was the same company that when I inquired about the higher cost-of-living expenses and moving costs, was told by the CEO that "if you want to make games you have to be willing to eat ramen for awhile". For the job title, I was making about 40% of the area average.

A whiny customer came in.

When they dropped off their machine last week (an HP all-in-one that came with a wireless mouse and keyboard), I noticed something was odd: the 7 key was missing. The rubber contact and scissor-switch was still present, but the button itself was gone. In addition, the wireless mouse was hosed, the left mouse button working only intermittently. Figuring that this was just the way the machine was, I fixed the issues and called them in to pick it up.

Suddenly the missing key is our fault and now we're irresponsible and they want a replacement. Not having the exact replacement in stock, I offer the closest thing: A like-new solar-powered wireless keyboard that retails for about $90. The only issues with it were some light scratches on the side.

Old lady notices the scratches and goes berzerk, saying that we're trying to rip her off. I explain that it's the closest thing I have in stock right now and that I cannot do anything else. She states that she'll take it, but she won't be happy with it, and that she's upset that she needs to learn an entirely new configuration (read: the delete button is slightly smaller) to use her computer. She's going on about how we betrayed her trust and all this that and the other.

Yeah, I'm writing up a separate disclaimer sheet that people will need to sign. I'm thinking that when we get a computer in, we inspect it first for these issues, then if we find any the customer will need to sign off acknowledging that they exist. It won't cost extra or anything (and if they want it repaired we can certainly do that too) but I'm really annoyed that this lady wants to bitch about recieving $110 in merchandise.
