Huh.  "Collections" are what I wanted when this whole G+ started nearly 4 years ago.  I fear it may be too late for here now, but I hope that Facebook copies it...

Googlers: How limited is Google Takeout?  I was trying to grab individual labels from a GMail account and after three it just says "Oops, something went wrong!"

"Sorry, you are trying to create too many archives. Please try again later. [Help Center]"

The Help Center, like all Google documentation, is absolutely and completely useless -- not even mentioning this case at all.  (Like, seriously, I think all google "Help" links should just result in a pop-up in 96 point type saying "FUCK YOU!" -- that's about how helpful they are.)

That is totally helpful, and not where the [Help Center] link goes to.  Thank you!

Dear LazyPlus,

I upgraded my Mac to Yosemite, and now I can only connect to my Time Capsule once without rebooting.

That is, I can connect to it once (as a file server or backup target), but if I unmount it then I can't connect again until I reboot my Mac.  I get "Connection Failed", and logs say:
12/5/14 5:31:20.125 PM NetAuthSysAgent[510]: DNSAddressResolver:Resolve CFNetServiceResolveWithTimeout failed
12/5/14 5:31:20.125 PM NetAuthSysAgent[510]: ERROR: AFP_GetServerInfo - connect failed 64

Airport Utility is also unable to see it, even though I'm connected to it and the Internet.

Apple software updates seem to be just gigantic piles of fail these days.  Does anyone have a solution for this?

This does seem to be a common problem in web searches, with no actual answers.  Or, rather,  most of the answers are special-case and don't apply (i.e. diasble firewall)

Dear Gmail,
When you take an inexplicably long time to Send a message so I go and start reading other messages I've not yet gotten to, the right thing to do is to asynchronously SEND THE DAMN EMAIL.  It is not, under any circumstance, leave the message in Drafts until I discover it several days later.

I can't even count how many times this has happened to me.  It's infuriating, but then, so is almost all of the GMail web interface.

No Love,
--Me

Jered: I only asked someone about it. But they didn't know what was up. If I had to guess, it was probably a bug that others noticed too. I'm glad it's better now.

This seems like a more technical venue than FB, so I'll try it here.

Does anyone here do anything beyond "may use TLS" in their SMTP infrastructure?  It seems like it would be nice to require encryption, or even (gasp) check certificates, but I don't see that being conducive to actually sending or receiving mail.

+Jered Floyd I think there are 2 answers. One is that not bothering was primarily a historic response and it made sense in it’s context. As said, more of the large email providers are enabling that.

The other is that as +Thomas Bushnell, BSG says, end-to-end encryption is probably a better choice.

Of course, no real harm in having both.

Back over on LiveJournal, +FJ van Wingerde explains why Brendan Eich, a pernicious homophobe, being named CEO of Mozilla is a Big Fucking Deal, and why we shouldn't stand for it.  I really have nothing further to add.

Dear Google+ (and Google in general),

Some day, I pray that you figure out how to fix your horribly broken authorization systems for multiple accounts.  There are security industry experts who know how to do this, you have lots of smart employees, and yet you consistently ignore every best practice in the book.

For example, my company has "gone Google" (and don't even get me started on the various disasters there), so I end up being logged in to both my personal and work Google accounts.  It appears that one of them is the "current account" as far as Google is concerned, although it's not clear on what basis -- it definitely isn't "last used".

When I try to go to G+, much of the time I get "Google+ is not available for your organization ([company domain]). Please contact your administrator to enable this service."  That's it.  No little selector to choose any of the other logged in accounts, just a dead end with no links at all.

When this happens I have to spend several minutes fucking with things before eventually logging out of my work account entirely to try to get to G+.  This usually works.

WTF?  Why is this so hard for you?

No love,

+1 To +Greg S's suggestion of using separate browser profiles for this. I have separate Google work and personal accounts and I am logged into both every day at work and have no problem with it, as long as each is in a separate profile window. (I also work at Google, but in an area far removed from this account stuff.)

Dear LazyPlus:

Another Mac OS Yosemite problem; maybe someone can explain?  I'm finding that I am intermittently not able to connect to my mail server from Firefox or telnet, which a totally unlikely error.  This is easily shown in two simple commands:

[~] jered% host zimbra.convivian.com
zimbra.convivian.com is an alias for hiro.convivian.com.
hiro.convivian.com has address 72.5.31.108

[~] jered% telnet zimbra.convivian.com 80
zimbra.convivian.com: nodename nor servname provided, or not known

WTF, resolver?

Love,
--Me

So, I believe both this and my previous complaint (not connecting reliability to the local Time Capsule) both have something to do with mDNS failures.

I think this because there seem to be mDNS queries around the failing connections, and dtruss is reading files like /etc/.mdns_debug around the same time, so this is all quite circumstantial.

I'm not at all clear on how to debug this further - I've never "set up" mDNS and none of my devices have obvious configuration tweaks around it.  I'll look at some packet traces next, I guess.

Durability problems in Linux LVM2 Snapshots?

I've just started using LVM snapshots on Linux, and am finding that they... aren't.  That is, the data is changing.  For example:

matrix:~# lvcreate -L1G -s -n hiro-backup /dev/matrix/hiro-root
  Logical volume "hiro-backup" created
matrix:~# md5sum -b /dev/mapper/matrix-hiro--backup
aeff90770c48e88e54e7d9c6a8e9a114 */dev/mapper/matrix-hiro--backup
matrix:~# md5sum -b /dev/mapper/matrix-hiro--backup
f1d4a2fb268ebc43f273d00d00f7e666 */dev/mapper/matrix-hiro--backup
matrix:~# md5sum -b /dev/mapper/matrix-hiro--backup
3615adce9adab4285a2f2fffe0ad7b85 */dev/mapper/matrix-hiro--backup
matrix:~# md5sum -b /dev/mapper/matrix-hiro--backup

I'm not overrunning the snapshot journal.

These don't appear to be mis-reads from the disk, in that the data that changes seems plausible revisions like changes to log or state files. (I'm using these snapshots for backups, and I've compared them.)

This is an older kernel: Debian 2.6.26-26lenny2

I'm aware that the snapshot is r/w, but there is no process writing to it.

Am I missing something about how LVM works?

The snapshot isn't overrun, and I've also mounted it read-only in further testing.

The volume is the backing device for a local Xen guest. The VM is running (it's a mail server) but it can't write to TJ snapshot - it's not even mapped to the VM.

Googlers: My company switched to Google Apps for Business, and I'm not going to rant about that again now, but I'm noticing a problem.

Every time our sales people create a calendar invite for anything, it includes a Google Hangouts video call link.  We don't use Google Hangouts for Webexes with customers, because that would be insane.  However, these Google Hangouts links get included on every invite, including ones that include a valid WebEx (well, GlobalMeet, same thing) link and customers get confused.

How do we get Google Calendar to stop trying to force every last bit of the G+Ecosystem onto us?

Hangouts is designed for a specific purpose, telepresence meetings, and it does that well.  It's not set up for the use case that WebEx and GlobalMeet and others serve.  For example, when I join a hangout, I get a video chat.  That's almost never what I want for work.  I want a system where the meeting leader can join ahead of time, set up slides for presentation, have a list of attendees and be able to mute and message them, set up polls if needed, be able to connect audio-only participants via a dial-in number, etc.  Most of those individual things can be done with Hangouts (no dial-in numbers, though, which is critical), but the workflow isn't set up that way.  It's not a product for business.

If you follow the link I sent above, if you have GAfB the individual users have no way to disable auto-hangouts, for their comfort and  safety.  It has to be done at a domain administrator level.

Following up on my previous complaint, this is a great explanation by the author of a bunch of great math videos on why she quit YouTube.

Basically, Google used to engage users by creating great products that people wanted to use.  Now, Google's focus is on tricking people into spending more time on Google sites in an attempt to find what they're looking for.
The choice between having to use Google+ and never commenting on YouTube again is laughably easy for me. I invested so much into my YouTube channel, and they're taking that investment and threatening to throw it away if I don't also start investing in Google+. No thank you Google, ...
