It's annoying to admin. You can't search it. It loses messages. That last part

You answered your own question, but...

Because then we (the ops staff, the guys actually doing the work here?) don't
have to deal with mailman breaking, we don't have to deal with deliverability,
we don't have to deal with a snowflake email service.

Your assumption that open source software is superior for a purpose simply
because the code is available is grossly inaccurate. Especially when it comes
to mailing list software.

Unless you're offering to fix mailman, in which case I look forward to seeing
your fork on github.

Because mailman isn't great and causes problems that are hard to diagnose, 
harder to fix and cause a great deal of complaints from users. These 
aren't specific to our lists and are common complaints from mailman sites.

The entire infra team reviewed the listbox.com option and are satisfied 
with their service, including the ability to pull data back out if we 
should ever need to self-host again.

Quite apart from the core software complaints about mailman, administering 
mail infrastructure takes time. Every day, thousands of messages of spam 
gets pumped into our lists and action is required to clear this out. 
Running quality production mail infrastructure consumes time, resources 
and isn't free. The administration team would prefer to dedicate their 
time to improving core services for getting the job done, not re-inventing 
the wheel just to handle list services.

Running project infrastructure is a thankless job. An extremely thankless 
job. It consumes a lot of time and when things are done properly, the 
result is often invisible to the users.

Re: [illumos-Discuss] Proposed migration off Mailman

I'd like to summarize my two cents on this matter, since I've had to repeatedly look into open-source mailing list management over the years. Mailman is, for most uses, the best thing going for lists. However, the various issues which lie at the very core of the product make me tend to recommend the much-reviled Majordomo in preference, generally. No amount of open-source advocacy (well-intentioned, misguided, or otherwise) is going to make any of the currently-available options as "pure open-source" less sucky. As I hinted above, "fixing" the problems with Mailman will require some fundamental changes which would, effectively, make it a different product. Illumos isn't out to reinvent a wheel that is unrelated to its direction, especially when a solution that solves the problem is being graciously provided. (The same is true of many other open-source projects which end up using less-than-"purely open source" solutions for some of their infrastructure.) If you're willing to fix/fork Mailman, there will surely be MANY very happy users. Illumos may even end up considering your version at some point. However, no one has been able to solve this ongoing problem. So, rather than hope for a miracle, taking the provided option is the only sensible approach. And if you're not aware of its myriad shortcomings, perhaps you should try running some fairly active lists with it for a while. ;) That is likely all I'll say on this matter. --Matt Sent from my HTC Touch Pro2 on the Now Network from Sprint®.

[illumos-Discuss] SSD vs "hybrid" drive - any advice?

I'm looking to upgrade the disk in a high-end laptop (so called
"desktop replacement" type).
I use it for development work, runing OpenIndiana (native) with lots
of ZFS data sets.

These "hybrid" drives look kind of interesting, i.e. for about $100,
one can get:
  Seagate Momentus XT ST95005620AS 500GB 7200 RPM 2.5" SATA 3.0Gb/s
with NCQ Solid State Hybrid Drive
  http://www.newegg.com/Product/Product.aspx?Item=N82E16822148591
And then for about $400 one can get an 250GB SSD, such as:
  Crucial M4 CT256M4SSD2 2.5" 256GB SATA III MLC Internal Solid State
Drive (SSD)
  http://www.newegg.com/Product/Product.aspx?Item=N82E16820148443

Anyone have experience with either one?  (good or bad)

Opinions whether the lower capacity and higher cost of
the SSD is justified in terms of performance for things
like software builds, etc?

Thanks,
Gordon

Gordon,

You'd be better off asking this question on zfs-discuss <at> opensolaris.org,
where most of the ZFS folks still hang out.

IIRC, the last time we talked about experiences with hybrid drives, it
was pretty clear they were doing solely read-caching with the NAND, so
ZFS would derive no benefit from using one as ZIL vs a standard HD.  The
NAND is completely internal to the HD, and thus, there is no way for ZFS
to take specific advantage of it in any form. 

Write speeds of SSDs aren't any faster than that of Hard drives in terms
of throughput; however, they can generally handle an order of magnitude
greater IOPs, even on writes, so compiling should be noticeably faster
(screamingly faster reading, somewhat faster writing, of lots of small
files). In your scenario (compiling), I don't see the hybrid HD's cache
being particularly useful vs a standard HD - you're doing a large number
of reads across a very large number of files, so I would expect that the
hybrid's NAND cache experiences a rather high rate of eviction, which
reduces its utility greatly.  And, there's no write benefit, so
compiling output to the hybrid will be just as slow as a normal HD.

I'd go with the SSD. Generally, the newer SanForce2 or 3-based internal
controllers seem to be a good bet on any SSD, so look around the Net to
see if the particular SSD you're interested in uses a SanForce2/3
integrated chip.

I have a Momentus XT in one of my laptops. It makes a big difference, but 
that's mainly because of the workload on that machine - it runs Windows. I 
wouldn't expect to see the same clear performance improvement on a 
development machine. Basically, if you have a lot of static data that gets 
read regularly, it'll move into the SSD cache. If things aren't static, it 
can't really offer much.

Ideal for making Starcraft 2 fire up quickly, though!

My hybrid sucks.  Bad caching algorithms, I think.  I have the Seagate.

Gordon,

I doubt you will see anything useful from a ZFS view point as you can't setup the flash component as a ZIL.

I use one in my Macbook Pro , but for my use case is see only margin performance improvement. It boots faster great it you spend you day booting boot test's. Common use apps load faster but again I don't spend my day closing and opening my browser or terminal.

For me personally I wouldn't last my money if I were to do it again, for what that's worth.

cheers

alan
