4/4 JVM usually takes care of stack memory fragmentation right? (Sun's
\_ Wrong. You've confused stack & heap.
JVM is mark&sweep with conservative compacting algorithm) What
about compiled code? Let's say I have a C/C++ server running that
keeps doing new+delete, some big, some small. Eventually, there will
be a lot of fragmentation. What happens?
\_ This depends on what your server is doing. Depending on your memory
allocation regime you may consider using a garbage collection
library or implementing your own memory management layer.
\_ C++ by default ends up fragging the heap. In general, assuming
you don't run forever, this isn't too bad a problem. If the
server is doing alloc/free's all the time and runs for a long time
you should consider rolling your own memory allocator. - seidl
\_ Yeah, it's like this: either you care a LOT about memory
performance, or you prefer to have ease of use. If you
want ease of use you just alloc away and don't care. If
you want performance you write your own allocator that
does exactly what you want. In games we use a mixture
of these two things based on how frequently a particular
allocation is going to happen. -blojo

4/5 Let's say I have a big NT server running and I want my UNIX box
to share the files. What do I have to install on my UNIX box?
(kinda like reverse NFS)
\_ samba (both client and server exists)
\_ get your terminology straight. You want the UNIX box to
ACCESS the files, not "share" them.
\_ Well, first: you really _want_ to do it the other direction.
If you can't then: installing samba will get you ftp-like
access to those files. If you want it to appear as a transparent,
mountable filesystem, either run linux (which as an fs module
for this), or use Sharity (Light or otherwise), which let's you
fake samba mounts as NFS mounts: http://www.obdev.at/Products
--dbushong
\_ Sharity (ex-Rumba) or Sharity-light is a UNIX-based SMB client
that'll mount Windows shares as UNIX filesystems. smbclient
is another ftp-like program that comes with Samba, that lets
you play with NT shares. -John

4/3 RAID 3 or RAID 5 for an NFS server supporting a small workgroup?
Files can be large (100's of MB but less than 1 GB) and users will
have the ability to write locally to the RAID (as well as through
NFS). Just to be clear, the machine will support typical user
activities as well as serve the large files. Lots of reading and
writing both small and large files. Benchmarking using iozone
is inconclusive. I am leaning towards RAID 3, though. This is a Solaris
Enterprise-class server. Anyone have any real-world experience
with which yields better performance? Thanks. --dim
\_ Idiot. There are probably hundreds of papers on this, online,
yet you ask onthe motd. Then ignore the BEST advice, which is
to scrap both of them and use 1+0.
RAID3 can be faster, but performs worse in degraded mode,or
something like that.
\_ What class server? It kind of depends, since if you have something
like a 4500 available, you're not going to notice any performance
impact for most things a "small workgroup" will be able to do.
Also, you'll want to know how much i/o your disks (array?
internal? SCSI? Fiber?) can handle at any given time, since if
you're doing a lot of moving stuff around, your bus may choke
before you need to start worrying about RAID performance. Also
maybe play with different stripe sizes. I'd tend to RAID5, just
because I've had too many disks puke on me, and because I
usually don't need to do a lot of writes, assuming you can't do
0+1. -John
\_ Oh yeah, if you run Veritas, version 3 can do 1+0, which is
pretty spiffy. -John
\_ They both suck. Use 0+1, disk is cheap. -tom
\_ tom is right. Unless your RAID 5 is hardware RAID 5
with a serious RAM buffer, your performance will lag.
Test it yourself by making a RAID 5 partition and 0+1
on the same machine, and do some benchmarks. Here's
some numbers to give you a feel:
time mkfile 1024M test
Raid 0+1 Ultra 450 2 X 296 MHz:
0.0u 21.0s 0:52 39% 0+0k 0+0io 0pf+0w
NO Raid, Single disk, Ultra 450 2 X 296 MHz:
0.0u 17.0s 1:28 19% 0+0k 0+0io 0pf+0w
Hardware Raid 5 Ultra 2 2 X 296 MHz:
0.0u 18.0s 1:37 18% 0+0k 0+0io 0pf+0w
Software Raid 5 Sparc 20:
3.0u 158.0s 19:13 13% 0+0k 0+0io 0pf+0w
(One of the twinks out here is using this as a home
directory server for the whole department and
can't figure out why everyone is complaining
that things are slow) -ax
\_ not that I dont agree that sw RAID 5 can be hazardous
to Sysadmin health, but is it appropriate to compare
software RAID 5 on a sparc20 running at what, 150MHz
max, versus dual ultra hardware RAID 5 , stripe/mirror
or simple filesystems? --Jon
\_ Thanks for the ideas, guys. I hadn't thought of
comparing to 1/0 numbers, so I configured that way
also. This is an E450 4x400 MHz running a SUN
StoreEdge RAID (hardware RAID). The disks are 18 GB
Fujitsu's (SUN OEM). RAID 3 beat even RAID 1/0 in
many benchmarks on this system. Even when not, the
differences weren't much. --dim
\_ raid levels have different performance characteristics
for different workloads --jon
\_ 0 - normal
1 - nothing gained from mirroring
2 - does this even exist?
3 - higher handwidth
4 - does this either?
\_ Yes, NetApps use RAID-4, but most other
systems skip straight to RAID-5.
5 - lower average latency

4/5 Discount gas vs. Brand Name gas question. (Original question was deleted
by a careless motd poster).
\_ The big oil refinieries auction their excess supplies and smaller
vendors like RR or Costco buy it at these auctions. This is the
same gas (octane and all) as the big companies. The only thing
that you have to watch out for is that some of these smaller
vendors add more cleaners to thier gas, thus you think that you
are getting more gallons of gas for a cheaper price, but in
reality you are not getting as much gas.
\_ What exactly does "add more cleaners" mean? Are they adding MTBE
or what? Will the cleaners damage the car's engine? Rotten
Robbie's 92 octane around my area is about $1.99. Cheaper than
the crazy $2.15 that I've seen in some Chevrons.
\_ I don't know what the percentage of cleaner to gasoline
is now, but it used to be something like 10/90 at most
brand name stations (shell,chevron,exxon), 15/85 at
BP/Mobil/76, 20/80 at Arco and 30/70 at RR. Don't know
\_ Do you have the source for these numbers?
\_ Yeah, the numbers sound bullshit to me too...
Gasoline in California is very tightly regulated,
and it's very unlikely that you can have 20% more
"cleaner" in it. If what the anon poster meant
\_ but isn't it funny that gas with more detergent
was MTBE (which is not a cleaner at all), then
the limit is 15%. --nevman

might be bs since this guy was a RIDE BIKE!r.
Just as a side note, I don't believe any of this.
I usually get gas at the service station nearest
to my house which happens to be a 76. I used to
get arco all the time for my Corolla since thier
89 octane was much cheaper than the others. I
now need to get 92 octance for my Lincoln and
all of the places around my home (w. sj) are
about $2.05 - $2.07 so it doesn't make much
difference.
about Costco. I don't think that the cleaner damages your
car (my dad says that it damages the fuel injector, but
I haven't seen that in my corolla with ~ 50K miles, YMMV).
You just have to be comforatble getting less gas for your
$s.
\_ but isn't it funny how gas with more detergent
in it essentially is sold as higher class gasoline?
"People think they're buying chivas regal for
their cars" Now with MORON, NEW SUPER
PREMIUM UNLEADED" -tpc
\_ Some car companies will refuse to honor
the warantee if you use a gas of a lower
octane than the recommended. If you
bought a MB,Cad.,Linc.,BMW,Jag. buying
92 instead of 89 octane shouldn't make
a big difference to you monetarily. If
you need to buy cheap gas in order to
save money cause your car cost too much
you should have bought a cheaper/more
affordable car and you should get a CLUE!
\_ Hm. I've been getting a lot of gas recently. How would I
go about auctioning THAT off?
\_ Let me know if you find any buyers. I've plenty.

that you can buy from them. |

\_ Agreed. BS and MS guys are much better coders than PHDs.
Some PHDs are good designers, but some just have thier
head up thier ass since they haven't every had to get
anything to work with a deadline/customer on the phone.
\_ Use 4 spaces (or tabs) to align code properly.
Use carriage returns before and after brackets.
Be consistent with other white-space use (parentheses).
Now even if you do write crappy code, others will be able to
identify the crap quickly.
\_ the use of spaces (instead of tabs) is bad. Recommend using
tabs to indent. 8 is more standard than 4, but yes, 4
looks better.
\_ Use Of Spaces Instead Of Tabs Considered Harmful.
\_ Oh..... how I *DESPISE* how some code editors represent tabs
as 4 spaces in the default setting. Tabs are goddamn 8
spaces.
\_ Why? Because they take more bytes to store? With disk prices
these days is that really a concern? Can any editor not handle
the spaces? Hell, at least everyone sees it formatted the
same. You have a problem with maintainable code?
\_ imagine an environment where people use MS Visual C++,
vi, emacs, notepad, etc. Each one treats tab a certain
\_ notepad always treats tabs as 8 chars,
and god forbid i look up the tab spacing
command in vi
way. Its easy to use across different editors. Also,
emacs, for example, has a special mode which works
very well with tabs. See C-Mode in emacs.
\_ The fact that each one treats tab (sic) a certain
(and different) way is why spaces are better.
\_ Are you arguing for or against tabs?
\_ for tabs
\_ All my editors handle spaces/tabs as whitespace for
indenting/hilighting, etc. Of course, I don't use emacs.
This just seems like a cry not to break your .emacs --
sorry but not all of us use emacs.
\_ I believe if you looked through industry code
most use tabs. And most of those coders were
probably not emacs users.
\_ Uh, I am in industry. And many people I know have
agreed with me on this one. Hence many uses
spaces instead of tabs.
\_ Industry is mostly divided between vi and
emacs, with some companies favoring one
more than the other. At Sun I heard its
mostly vi, while at Cisco (from experience)
its recommended that you use emacs (lots
of homegrown lisp for development).
\_ Just use C-Mode in emacs. It does all the indenting correctly,
and you can easily tell when one of those vi lusers edits your
source files since the indenting will be off.
\_ .emacsrc foo required?
\_ Reading through K&R is worthwhile, but nothing beats writing lots
of code. -dans
\_ "Deep C Secrets: Expert C Programming" is a much more useful book

\_ This is an excellent book and should be required

It also helps your fu!
\_ you can't improve your C coding skill without understanding the
big picture. A thorough understanding of machine architecture

required. Being a good programmer is more than just reading
"Learning C in 21 Days." If you want to be a good programmer,
go to a community college. If you want to be a good computer

Benchmark a java servlet that does jdbc
odbc access using a connection pool
against a perl cgi that needs to open
a db connection every time it is invoked.
Java beats the pants off of perl for
most transactions. Same for LDAP. I

\_ Tcl/Tk is pretty junky compared to Perl. If you need
to use a scripting language use Perl or Bourne Shell.
\_ there really is no point in doing Tcl in my opinion.
Instead you should use python. It's easier to learn,
it's easier to write wrappers for your C code in it,
it runs faster (actually, i don't know about tcl8.0),
and it's got builtin support for OO. -ali
\_ I checked out the python web page and it does seem
pretty nifty. I'll try using it next time instead
of Tcl. Thanks. -emin
\_ Any language that uses white space for scope
is pretty junky. Next they will dictate the
columns that I can use. Fortran anyone?
\_ tcl + python are academia languages and are USELESS
