Historical errata for Using memcached

The creator of LiveJournal, Brad Fitzpatrick, is incorrectly referred to as “Brad Fitzgerald.”

This booklet is very good. I have one request: It seems this PDF is not indexed. I have tried to search it using either skim, spotlight or preview and it finds nothing.

So, please, please, can you index it?

Thanks.

“One way to remove date from memcached is to delete it”

should read

“One way to remove data from memcached is to delete it”

- first paragraph, first sentence -

If you’re code has been written to minimize cache stampedes then this should be a minimal impact.

“You’re” should be “your”, this should “have” minimal impact

@Sidebar “Not ever client supports compression.”
Should be “Not ever[y] client…”

@first sentence on page:
“…you need to be prepared to get handle an error code and respond to it”. To handle is to respond; sentence needs to be reworded.

“The simplest is flusha_all.” should be “The simplest is flush_all.”

“With memcached, the web page check memcached” should be “checks memcached”

In the side bar, the last paragraph reads: “…but you should
now it’s here so you can…”. It should be: “…but you should
know it’s here so you can…”. Summary: instead of “now”, it should be “know”.

Section 4.6 paragraph 2, “If you’re code has been written” should grammatically be be “If your code has been written”.

Line 6 of the script uses “deb01:11211”, but the sidebar implies that “deb01” should be shown as an IP address (like the “192.168.0.80:11211” on line 7).

Brad Fitzpatrick’s name is given as “Brad Fitzgerald”.

Last line on page contains double negative “isn’t not” which should say “is not”.

Brad’s name is Brad Fitzpatrick, not Brad Fitzgerald, as the text reads. See his personal site or Wikipedia article.

because multiple servers for an application will be
storing differen sets of data.

differen->different

In the calendar of events scripts:

my $lockKey = sha512_base64($statement.“:lock” );
my $key = sha512_base64($statement);

If the order were reversed, it could be:
my $key = sha512_base64($statement);
my $lockKey = $key . “:lock”;

Both are still unique, and it saves an sha512 and base64. It does mean the key sizes are different, but the saved computing time could be used for something more fun. :)

The GetCalendarOfEventsDB (–3.pl) needlessly recalculates the key on line 25 when inserting the result of the database lookup into the cache.

“Let’st start with” should be “Let’s start with”

“with the each of the $dataKey” should read “with each $dataKey” or “with every $dataKey”.

cmd_misses -> get_misses

context for #48697: This data is actually derived using cmd_get, get_hits, and cmd_misses.

enable_comprss->enable_compress
Context: enable_comprss only works, however, if the compression threshold has been set

tempest url no longer works, alternate:
shakespeare.mit.edu/tempest/full.html

“differen sets of data” near the end of the first paragraph.

First line under Server Hashing: “retreive” should be “retrieve”.

In the sidebar, “Not ever client” should read “Not every client”.

First paragraph, second line “programing”.

Second paragraph: “memcached limits they key size”
