- 24jul2014 Fixr (permalink):
I've written a Flickr API app that includes a couple different fixes
to inadequacies in Flickr. You can pick and choose which ones you
want to enable. Current offerings:
- Geotag Interoperation
Standard geotags look like this:
When Flickr first implemented maps back in 2005, they used this
standard format. Later they switched to a non-standard custom system.
If you prefer to use the standard tags, this fix automatically
copies them to Flickr's system every night.
geotagged geo:lat=37.88185 geo:lon=-122.29556
- Set Sorting
All image sequences throughout Flickr are shown with the newest
image first and oldest image last, with one exception: sets. Sets
get new images added at the end, instead of the beginning. If you
don't like this inconsistency, you can reorder your sets every time
you add to them, but that gets tedious. This fix automatically
reorders your sets every night.
Here's the URL: http://acme.com/flickr/fixr/
- 19jul2014 ChuMaker Update (permalink):
I took a break from clangification to do a little update to the
Now the images are 60% larger.
- 16jul2014 Clangification (permalink):
After three weeks or so I'm getting down to the short strokes on
my clangification project. Out of an initial couple of hundred
packages I'm down to five.
mini_httpd and thttpd - these are ready, but I still need to install
them here and do some testing since they are pretty mission-critical.
xsplinefun and xsquig - a couple of old X display hacks. These build
just fine, but they only run on color-mapped displays, which don't
really exist any more. I want to update them to work with modern
24-bit screens, so I have to re-learn some Xlib stuff. I guess
I can release clangified versions now and fix them to actually
pbmplus - ready, but I have a backlog of a half-dozen new programs
and scripts to integrate before I can do a release.
All the rest now build cleanly with clang!
I've also updated all the corresponding web pages to be HTML 4.01 compliant.
- 25jun2014 FreeBSD 10.0 (permalink):
I am finishing off my first FreeBSD 10.0 install, on my new desktop
machine. I thought I'd post some notes here.
The hardware is an HP Pavilion 23 "all in one". Nice big screen,
four core CPU, 500GB disk. $500.
The first problem I ran into was that it wouldn't boot from the
install media. This was "Secure Boot" in action. I had to figure out
how to get into the BIOS settings page (ESC while booting), disable
Secure Boot, reboot, enable Legacy Boot, then boot into the install.
The second problem was that after the install process completed,
the BIOS claimed it couldn't find anything to boot. I asked around
and guessed the problem was the HP BIOS couldn't deal with GPT,
so I redid the install with old-style BSD Labels partitioning.
That was more complicated than it should have been because the
10.0 installer switched from sysinstall to bsdinstall and the
partitioning page is just different enough to confuse old-timers
like me. I ended up doing something ridiculous: starting a 9.2
install, partitioning using good old sysinstall, quitting, starting
the 10.0 install, and skipping the partitioning step. Anyway,
After that things went pretty smoothly. I installed rsync from
ports, Xorg and Firefox from packages, and everything is running
pretty smoothly. My remaining issues list:
Figure out how to update the ports tree. I think this is something
like "portsnap fetch ; portsnap update" as root, except not from
a cron job.
Figure out how to update the packages tree too.
There's no bell. Sound works, aside from that. Bell is also
absent in the raw console, and even at boot time, so this is
something pretty basic.
The HP keyboard kind of sux0rs, I will probably get a new one.
The mouse is ok, hardware-wise. However,
The mouse is too sensitive for me by a fairly large factor,
at least 2x maybe even 3x. None of the various things I've tried
for slowing it down have worked - they don't seem to change the
pointer speed at all. This includes xset and a couple of options
There's a trivial bug with xterm's cursor. It's supposed to be
a hollow rectangle when the window does not have focus and a solid
rectangle when it does. However, when the mouse pointer goes directly
from Firefox to an xterm, the cursor stays hollow. The xterm still
gets focus, but the cursor does not change. I used xev to look at
what events the xterm is getting and found that in the broken
case, where the cursor stays hollow, xterm gets a FocusIn event,
while in the correct case it does not. Kind of the opposite of what
I was expecting. Google shows some folks ran into a similar-sounding
issue with xemacs instead of xterm a couple years ago, and had to
change some xemacs code to fix it.
Finally, in FreeBSD 10.0 gcc is no longer installed by default,
it uses clang instead, so I have been making sure all my software
builds cleanly under clang. I have a couple hundred packages to
go through so this will take a while. The first thing I did is edit
all the Makefiles so instead of calling gcc explicitly, they call
cc, which is a front-end that calls gcc or clang as appropriate. So the
packages will build unmodified on either variety of system. While I use
very few of those hundreds of software packages on my desktop machine,
starting the clangification process now will make things easier when I
switch my server to 10.0 later.
- 24may2014 countdown (permalink):
I added a new little program to the ACME freeware collection.
It counts down a specified time interval.
I use it mainly as an egg timer.
- 13may2014 Overheated (permalink):
We had a heat wave predicted for today.
It didn't actually get that hot - except inside acme.com.
I got home at 9pm and a motherboard alert tone was going.
Opened up the case and the problem was obvious - a wire had gotten
caught in the CPU fan and stopped it.
I moved the wire away, the fan started, and the alert tone stopped.
Here's the CPU temperature graph. Looks like it didn't get hot
enough to fry.
As for why the wire moved, I found a rotted rubber band at the
bottom of the case - time and temperature did it in.
Tie-wraps are much better.
- 22nov2013 New Map Versions (permalink):
I have installed new versions of all the ACME maps.
This was necessary because Google finally retired version 2
of their Maps API, so I had to switch everything to version 3.
I resisted switching as long as possible because version 3
seems much slower, but the time has come.
Most of the code conversions were fairly simple, but ACME Mapper
took a few extra days since it is by far my most complicated
version number to 2.1 - if you are still
seeing "ACME Mapper 2.0", you have the old version.
Try clicking Reload and see if that gets you the new one.
If you use other maps such as
Two Maps One Scale,
you may also need to click Reload to get the new one.
- 26jun2012 Denial of Service (permalink):
Some of you ACME fans may have noticed poor response times on the
web site for a couple weeks.
You were not imagining it, and it wasn't just you.
Acme.com was undergoing a denial of service attack.
It started early in June and lasted two weeks, on and off.
The attack consisted of a flood of UDP DNS packets from a variety
of source addresses, all asking for any records associated with the
Acme.com does not provide DNS service and never has.
The DNS port is closed, the packets did not get in, they were just dropped.
Nevertheless, the sheer volume clogged up the internet connection and
made it hard for anyone else to use it.
You can see the effects in the graphs on the right, as dropped packets
and increased round-trip times.
Attacks like this are fairly common on the internet these days.
I heard through the old-skool hacker grapevine that other sites
got hit with similar attacks around the same time.
They are trivial to block, but because in my case the limiting resource
is my internet link's bandwidth, I needed to block the attack on the
upstream end of the link.
That's when I ran into problems.
I called my ISP's tech support line.
I told them about the attack, and laid out two simple measures they
could use to block it.
Those were literally the first three sentences out of my mouth.
Either of the block methods would take me five minutes to accomplish,
so I figured an ISP's tech team should be able to accomplish the
same in a day or so.
After two weeks of daily phone calls and email exchanges, my ISP had
not managed to do anything.
The last email from them indicated they were about to do the exact wrong
thing, disabling the wrong one of my two IP addresses.
Luckily for me, that's when the attacker lost interest and decided
to go harass someone else.
All that was left for me to do was make sure the ISP trouble ticket
indicated that the attack had ceased and they should not do anything.
I had already been thinking about upgrading my internet connection.
This incident raised the priority of that task.
More bandwidth might have lessened the severity of the attack,
and I would definitely like to dump my current ISP over their
handling of this.
I am considering three options:
Your input is welcome.
- Fusion ADSL2+ from Sonic.net
- Comcast (but I'm not sure whether they allow servers)
- Co-locating at LMi.net
- 01apr2012 Ok, ok. (permalink):
Hah hah, April Fool.
I'll turn the color back on now.
Actually I needed to re-make all the photos anyway, because I increased
the size of the images from 576 pixels to 640 pixels.
So I did it twice instead of once.
Took over five hours each time!

- 06feb2012 Welcome Back AdSense (permalink):
Last week I blogged about how Google AdSense had cut me off,
sending two form letters with no specifics.
I appealed, and they denied the appeal.
I had no idea what was going on, and AdSense wasn't saying.
People had a bunch of theories for why AdSense disabled me.
Personally, I took AdSense at their (form letter) word, that the
reason was invalid clicks.
But you can see how the lack of specific information caused
folks to go a little bit crazy, assuming malevolent intent and/or
stupidity on Google's part.
- My site is too small to bother with.
- My site's design is too antiquated.
- They don't like me using the word "hacks" to describe my software.
- ACME Mapper is too similar to Google Maps.
- I am in fact a click-spammer but I'm playing dumb.
My post about this went a little bit viral on Google+.
Lots of comments, lots of re-shares.
Maybe half the comments were from other former AdSense partners
saying they had gotten the same form letters.
I want to highlight two of the comments.
First, by Matt Cutts, head of the webspam team at Google:
I can't easily imagine Jef Poskanzer was click-spamming AdSense,
while at the same time I trust the judgment and abilities of the
Another Google+er, Viswa Vutharkar, said this:
Take this example scenario.
Someone who hates acme.com created an elaborate bot net or somehow
influenced some legion of their followers to simply visit acme website
and click on ads willy nilly.
Its no fault of acme.
Anyway all the attention on Google+ got the AdSense folks to re-re-review
The attention did not affect the outcome, it just got me
a third chance, which I am very grateful for.
And the result was, I was reinstated.
So the first thing I did after my account was turned back on was to
go look at my stats.
That's when I found out that AdSense had been absolutely right to
flag my account.
There was a big bulge in the stats between late November and early
Views remained about the same while clicks rose by about a factor
I had nothing to do with it, of course.
But AdSense has to defend itself and its advertisers against stuff like this.
The way AdSense defends itself is, I think, poor.
As we saw above, the lack of specifics makes people play crazy guessing
It detracts from Google's reputation for trying to do the right thing.
And by dumping long-term partners like ACME instead of working with
us to solve the problem, it is unprofitable.
I have three suggestions to improve the process.
- Add a step between 'fully enabled account' and
'completely disabled account'.
Some sort of 'limbo' where ads are not running but the publisher
still has read-only access to the web site so they can see their stats.
- Send publishers an email alert when the fraud filters start
seeing something bad, instead of waiting a month and a half and then
disabling the account.
- Open up an authenticated API for automated fetching of AdSense
Then publishers could do their own automated analysis and generate
their own email alerts on unusual activity.
I remain, for now, a happy AdSense publisher.
And if we go another round and I get disabled again, well at
least now I know more about what's going on.
- 30jan2012 Goodbye AdSense (permalink):
I have been using Google's AdSense web advertising system since it
opened to the public, eight and a half years ago.
Aside from one quickly-resolved incident eight years ago,
Google and I have been very happy with each other and have
made a lot of money for each other.
Two weeks ago I got a form letter from AdSense telling me
that my account had been disabled.
The letter explained how I could file an appeal, so I did.
This morning I got their response to my appeal: denied.
That would seem to be the end of my relationship with AdSense.
Other folks dealing with AdSense might be interested in the
details, so I'll post them below.
But there's really not much, the form letters are nearly
devoid of information.
This is intentional - the first item in AdSense's
Disabled Account FAQ says:
Q. Why was my account disabled? Can you tell me more about the invalid
click activity you detected?
A. Because we have a need to protect our proprietary detection system,
we're unable to provide our publishers with any information about
their account activity, including any web pages, users, or third-party
services that might have been involved.
page on AdSense
includes a section of criticism with this paragraph:
According to critics, AdSense is one of the worst publisher programs
who really don't care about its publishers. Many cases were reported
about the accounts being disabled once a publisher reaches the
minimum payout amount of $100. Publishers will only get an automated
email which says that their site is a threat to the advertisers and
other publishers. The email contains a link to the help forum which
is unlikely to get the account reinstated, even if their account
was disabled in error. About 99% of affected publishers say that their
account has not been reinstated, and they believe that the termination
was done in error.
I don't agree with the rest of the criticism but this part would
appear to be both correct and alarming.
Here's the relevant part of the initial form letter:
Date: Sun, 15 Jan 2012 18:43:23 -0000
From: "Google AdSense" <firstname.lastname@example.org>
Subject: Google AdSense Account Disabled
After reviewing our records, we've determined that your AdSense account
poses a risk of generating invalid activity. Because we have a
responsibility to protect our AdWords advertisers from inflated costs due
to invalid activity, we've found it necessary to disable your AdSense
account. Your outstanding balance and Google's share of the revenue will
both be fully refunded back to the affected advertisers.
Here's my appeal, with my responses in italics:
Company's name (If applicable):
Example URLs where you've placed your ads:
http://acme.com/ http://acme.com/software/ http://mapper.acme.com/
Date your account was disabled:
15 January 2012
Have you appealed the disabling of this account in the past?
Do you have any other active AdSense accounts?
Who are the intended users of your site?
software developers, map users, photographers
From what parts of the world do your users view your site?
How are your users accessing the web? (e.g. Internet cafes, home DSL lines, mobile devices, university / office intranets)
Does your site content include content copied from other sites on the web (not including RSS feeds)?
What is the source of your site's content?
How many people are involved with the administration of the site?
How often do you update your site?
Have you ever purchased traffic to your site(s)?
Have you ever signed up for services that give users incentives to visit your site/ads? (e.g. auto-surf, pay-to-read, pay-to-click)
How do users get to your site? How do you promote your site?
My site is very well known, with links all over the net.
Why do you believe the traffic to your Google ads is valuable to advertisers?
I provide excellent and highly-respected services andsoftware.
Would visitors to your site have any reason to increase your AdSense earnings? If so, why?
Have you or your site ever violated the AdSense program policies or Terms & Conditions? If so, how?
In 2003 and 2004 there were a couple of incidents where ads on one of my software projects' pages were considered borderline invalid, because of how users were getting to those pages. We resolved the situation by removing the ads from just those pages. In the eight years since then the Google-ACME relationship has been very happy.
Any relevant information that you believe may explain the invalid click activity we detected:
I have no idea why your detector triggered.
Any data in your site traffic logs or reports that indicate suspicious IP addresses, referrers, or requests:
I took a look and saw nothing unusual. If you give me some hint of what to look for, maybe I could be more helpful.
Here's their acknowledgement of my appeal:

an anti-worm/virus mail filter.
Before installing this we were getting about three worms per second,
using up about 1/4 of the DSL line's bandwidth.
Clam AV rejects them earlier in the mail transaction, saving some
CPU cycles and possibly even some bandwidth by shutting them down before
the entire worm gets transmitted.

They seem like a pretty good broker.
For example, they let publishers set options like maximum ad size in bytes,
and whether to disallow animated ads.
First day's commissions were about $30, or $900/month, which is not bad at all
if it keeps up.
That's about twice what I was making at
my previous broker.
I also got about $20 of "promotional" money, which can be used to run my
own ads on other Aaddzz sites.
Guess I have to come up with an ACME Labs banner now.

It's intended as a simple testbed for trying out things like SSL.
It's surprisingly fast, though.
On my old 100MHz Pentium it clocked 70 ops/sec, 90% as fast as

I suppose forks are pretty fast when the program's size is minuscule - the
