An explanation of metal corrosion...
Background
I was the programming lead on a game whose purpose is to teach how metal corrosion
works, ways to protect against it (large scale), and the fiscal (also sometimes dangerous) impact of not taking
corrosion into account when designing and maintaining large structures. As a result of my position I had to
teach myself a lot about corrosion theory. Although we regularly consulted with some of the foremost experts
in the world, they can only take you so far. Talking with them sometimes, it's like a brain surgeon trying to
explain things to a first-year medical student; there's knowledge to be passed on, but the student has no
framework for receiving it.
So I'm writing this to hopefully offer a simple explanation for the layman about how
corrosion works. Keep in mind that this explanation concerns only metal corrosion. Also keep in mind that it's
a very general explanation. If you want to know more, go get a doctorate in Chemistry.
Introduction
Corrosion is usually erroneously described by its results; rust, oxidation, pitting,
etc. It's important to recognize the fact that corrosion itself is a microscopic process independent of
anything it produces. In general it is defined as the
act of the degradation of metal due to
interaction with its surroundings. In essence, corrosion changes steel (or other engineered metals) into a
substance that no longer has the same desired properties, e.g. strength, toughness, flexibility, etc. It can
actually be thought of as the reverse process of producing steel in the first place. To make steel, you mine
iron oxide, introduce large amounts of energy (heat) to separate the iron from the oxygen, then add carbon to
technically make it steel. But iron (steel, whatever, same thing) is actually an unstable little element.
Being now in a relatively high-energy state, it will naturally seek to revert back to its more stable iron oxide
form if left to its own devices. In fact, iron by itself hardly exists
anywhere naturally on the surface
of the Earth!
So in short, remember, nature doesn't like high-energy states (
see Entropy/Second Law of
Thermodynamics). A glass of milk on a table prefers to be on the floor. Iron and other engineered metals
are in a high-energy state, and so they have a tendency to return to a low-energy state; they do this through
corrosion.
Going Deeper
The above is a broad definition though. Going deeper, (breathe in) corrosion is an
electrochemical process arising from a electrical potential difference between two pieces of metal, connected by
an electrically conductive path (usually this means they are simply touching each other). Further, both metals
must be in contact with an electrolyte (e.g. salt water) capable of spurring chemical interactions with the two
metals, which in turn causes them to exchange electrons. This exchange of electrons implies an electrical
current, also called the corrosion current.
The above paragraph describes what is
essential for corrosion to occur. In
other words, you need (a) two metals with a potential difference, (b) an electrical path from one to the other,
and (c) an electrolyte that interacts with the metals to produce an electrical current between the two. Take
away just one of these and corrosion does not happen.
Collectively, (a), (b), and (c) are referred to as a corrosion cell. A corrosion cell
generally has very little physical analogue to real life, but rather is a tool for abstraction, so that
corrosion is easier to visualize. It's kind of like in high school how your science teacher shows you these
models of atoms, with concentric rings surrounding a giant nucleus. If you do any kind of further study, you
know atoms look nothing like that (indeed, atoms are too small to even "look" at in the first place!). A
corrosion cell diagram is a very similar tool.
The Corrosion Cell
But anyway, let's go a little deeper into the individual parts of a corrosion cell
(CC), starting with the two metals. In the context of a CC, they are referred to as electrodes. The anode is
the metal that corrodes, and (to put it simply) the cathode is the metal that doesn't. Which metal is the anode
is determined by its electrical potential relative to the other metal. The metal that has a more negative
potential will become anodic and corrode. Below is an abridged list of metals called the
Galvanic Series, with Gold near the top being the most "corrosion resistant", or "least active" metal. Therefore, if you put iron and copper
together in a corrosion cell, iron would corrode because it's the more active (more electrically negative) metal
of the two. Further, the distance between two metals on the series determines how fast corrosion will occur.
So coupled together, gold would cause iron to corrode much faster than would copper.
Galvanic Series
LEAST ACTIVE
Graphite
Gold
Silver
Titanium
Stainless steel
Brass
Chromium
Copper
Nickel
Iron
Steel
Lead
Tin
Aluminum
Zinc
Magnesium
MOST ACTIVE
Iron and copper is sort of the "classic" corrosion cell configuration, and in fact
modern study of corrosion was brought about when iron nails were used to fix copper sheathing in place on the
Royal Navy Frigate HMS Alarm in the late 18th century. Guess what happened when iron, copper, and sea water
were mixed together. The nails were damn near vaporized and so most of the sheathing fell off in no time. The
only pieces that remained were those that had been fixed in place by nails that still had the paper from their
packaging lodged underneath their heads, thus electrically separating them from the copper.
Another classic corrosion cell is the dry cell battery. Yes, every Duracell you've
ever used depends on corrosion to produce its electrical current. To relate it to the corrosion cell model, a
battery typically uses zinc as the anode, graphite (carbon) as the cathode, a special electrolytic "paste" to spur the
reactions, and the circuits in the device you're powering act as the electrical return path. So if the battery
isn't being used, one part of the corrosion cell is eliminated and so no corrosion occurs inside. A battery
"dies" when all the zinc is corroded.
Other Corrosion Cells
A potential difference between two metals can occur for many other reasons than just
the inherent properties of the metals. Temperature differences can play a big role. In a corrosion cell, the
higher temperature electrode, even if its metal composition is the same as the other electrode, can become
anodic. This is of importance in heating systems, where pipes close to the heater will have a tendency to
corrode because they have a more negative electrical potential compared to the pipes further down the line. This kind of cell is called a
differential temperature corrosion cell.
You can also have a differential aeration cell, where one electrode is exposed to more
oxygen or nitrogen, and a differential concentration cell, where one electrode is exposed to a different
concentration of electrolyte than the other.
All of these circumstances, and more, can lead to a potential difference between the
electrodes, which is the driving force behind corrosion. If there's no potential difference, there's no
corrosion.
But, Wait...
If you've actually continued reading this far, you may be saying to yourself, "Wait,
most of the rust I see every day is on just one ordinary piece of metal, like that old hammer in my garage. It
certainly isn't touching any copper, and one side isn't hotter than the other. So what gives?" This kind of
corrosion is surprisingly no different than what's described above. It is brought about by what are called
Local Action Corrosion Cells. Microscopic impurities on the surface of the iron lead to millions of very slight
potential differences, which in turn leads to millions of tiny corrosion cells. If you think about a sandbox,
even if the sand is completely level to the naked eye, up close, some grains will be higher than other grains,
and therefore have slightly more gravitational potential energy. It's somewhat the same case with a metal's
surface, except we're talking about electrical potential.
As a real life example of this, most knives have a "grain" in their steel perpendicular
to the edge. You'll notice that on old knives, you can sometimes see a rust pattern form along these grains,
with rust appearing in the valleys, because these valleys form the anodic (more active) regions of the local
action corrosion cells.
Another example, kind of, is that well-polished steel has less of a tendency to
corrode. This is because you're eliminating most of the "impurities" on the surface of the metal, so it's
harder for corrosion cells to develop.
How Do We Stop It
Mankind has known about corrosion ever since we made the momentous switch from stone to
metal. It's an interesting historical side note that our discovery and use of metal follows the Galvanic Series very closely. Gold was the first
metal used by man about 12,000 years ago because it exists in its metallic form in nature. Copper (bronze =
copper + tin) is more easily corroded but can also be found in its elemental form in nature, and so started to
be used about 10,000 years ago for tools and weapons. Iron wasn't isolated until about 3,500 years ago because
it requires sophisticated technology to smelt (separate from oxygen). Zinc is even further down the series and
wasn't discovered until the 16th century because of how difficult it is to produce. Sodium is explosively
reactive with water and so wasn't isolated until the late 19th century.
We didn't have much problems keeping Gold, Silver, Bronze, etc. in good shape. For the
most part, these metals require special conditions to corrode to the point where they become unusable. Iron was
our first big maintenance challenge, and up to about a few hundred years ago, the only real strategy to prevent
corrosion was constant TLC (tender, loving care). You had to keep your iron-based implements polished, oiled,
and out of the elements if you expected them to last any length of time.
Passivation
At some point however we came up with several great ways to slow down steel/iron
corrosion. The first was by alloying steel with chromium to create stainless steel. Unlike iron, when chromium corrodes, its oxide (chromium oxide) takes up the same volume as the chromium itself, and therefore has a tendency to form a passive film on its surface that in fact prevents corrosion from penetrating deeper into its structure. This is why stainless steel is known for its corrosion resistance, but it's not the steel that's doing the resisting, it's the chromium.
If you look at the galvanic series, you can see that aluminum is way down there, and so seemingly very corrosion
prone as well. But just like chromium, aluminum tends to create a passive aluminum oxide layer on its surface
very quickly, and so in practice it can be very corrosion resistant despite its high activity on paper. Just
look at soda cans.
Coating
Someone also had the bright idea at some point to coat steel with corrosion resistant
paint or seal it in rubber. These methods have and will continue to become more and more effective, though they
have obvious limitations for many purposes. The idea behind a coating of course is to cut off the electrolyte
component of the corrosion cell, just like passivation.
Others
There are many other strategies for preventing corrosion, but most work off the same
principle as the above two, so on to the mother...
Cathodic Protection
Passivation and coating are fine when you're talking about your tools or your car, but
what about if you want to protect a whole bridge, or building, from corroding? Although it can sometimes be
done, using passivating metals (e.g. stainless steel) and coatings can be costly and inefficient. But if you
have an understanding of how corrosion works, you can really nip it in the butt by pulling a fast one on nature.
Let's say you have a large freighter whose steel hull is corroding due to local action cells. Your corrosion
cell diagram for this case will have iron for both its electrodes, with the corrosion current being pushed by
the small potential difference because of the impurities in the steel's iron. So what if you replaced one electrode
with a metal that was guaranteed to be more electronegative (more active) than the most active regions of the
iron itself?
This is exactly what corrosion engineers do. They literally slap huge blocks of
magnesium (for example) onto the hull of the ship. The magnesium then corrodes preferentially to the iron.
Therefore the term "Cathodic Protection" can in other words be taken to mean "Protecting a Metal by Turning it
into a Cathode". Thus you are sacrificing the more active (and conveniently usually cheaper) metal to save the
other metal. This method of cathodic protection is unsurprisingly called Sacrificial CP.
The other method of Cathodic Protection is called Impressed Current CP. Fundamentally it's the same as
Sacrificial CP, but instead of using a more active metal to act as the anode, the anode is
simulated
using an outside power source. Instead of the anode of the cell being more electronegative than the cathode
(the iron/steel) by virtue of its own inherit properties, a power source sort of forces a current onto the
corrosion cell that makes it "think" that the anode is more negative. In this situation the "anode" doesn't
even really corrode, and in fact can have a much higher electrical potential than the cathode. As long as the power stays on, an impressed current system can protect a structure almost
indefinitely. By contrast, a sacrificial system only lasts as long as the metal you are
sacrificing.
Conclusion
Eh I'm done.

Get to know real Ostrava: a city with rich industrial heritage and unmistakable post-industrial fluidum not spoiled by crowds of tourists.
The old city hall from the 14thcentury was turned to the Ostrava Museum. But the city was built mostly in the 18th and 19th century when the industrial revolution began. Ostrava was built around one factory, and only a few buildings were there before that. As the main centre of coal mining and coke, iron and steel production in central Europe Ostrava was a unique industrial complex because it was the only area in Europe where you could find such technological flow in one place. Products made in there are part of Paris’ Eiffel Tower, or Australia’s biggest bridge.
As a key industrial area during communist era, Ostrava was nicknamed “steel heart of the Republic” and socialist realism influenced architecture was built along with parks with fountains, typical plane trees and statues of shining future for working men and women.
The unspoiled dominant feature of Ostrava is the Vítkovice area, the Hlubina mine complex, the blast furnaces and the ironworks coke plant which was placed on the tentative list of UNESCO World Heritage Centre.
The production ended in 1998 and the city went through a lot of modernisation in the past years. Nowadays, Ostrava is known for cultural events, festivals and sports events: almost every day there’s a new place opening: galleries, cafés, bars or bistros. And people who are very open and direct and very warm at the same time.
Watch a short video to get a quick overview of Ostrava architecture, culture and leisure activities.
Internationally recognized for its fresh voice and inspiration for discovering places by locals is USE-IT map. It’s a non-commercial and friendly application and also a printed map made by locals. This map of Ostrava is very well maintained and we highly recommend you to get one.
Don’t forget PyCon CZ afterparty on Saturday at DOV! But if you need to change air and want to see some bars or clubs, Stodolní street is well known for its nightlife. In case you are looking for hidden gems, locals prefer smaller, not so crowded places like Dock bar with nice atmosphere or a small bar with sophisticated drinks U Gustava, wine is good at Ostrawina and staying at Ikarus after midnight is always fun. Drink the best beers at U Skákavého Poníka, Psí kusy – HoppyDog, or the best Pilsen beer at Pivnice U Rady.
For delicious food we recommend you to try
eatmeat or HogoFogo burgers,
Bistro Boule za ušima offers burgers and more,
La Petite Conversation for French cuisine and salads,
a quite big place with a statue of pagan god of grain and beer Radegast is Radegastovna be sure try their smoked meat, burgers or salads,
Makalu has heavenly Nepalese and Indian food,
try desserts at Sladký časy and their French Croque Monsieur sandwich,
Superfood Black Kale is a vegan restaurant,
try Czech cuisine at Pivnice U Rady (reservation needed),
at Bo Bistro Store get classic Czech potato pancake,
get best fresh fish at Rybárna na Rynku,
stuff yourself with fries from the best Czech potatoes at Fæncy Fries
And maybe you can go to eat a bit more fancy and have a good beer or two at Zámek (Chateau) Zábřeh restaurant.
 You can find coffee shops around every corner.
We highly recommend friendly Kavárna Maryčka,
PetPunk hipster style café with something to eat by Pawliczka,
Industrial Cafe in art deco style,
Kavárna Daniel old times style with great café au lait

Teaching with multiple warp zones: Increasing engagement with assignment choice
Last knit: 2023-08-04
I lack positive emotions toward the process of grading in my courses. I have lots of positive emotions for my students. Grading stresses people out. I’ll save my thoughts about grading in general for another day.
What I really want to talk about is how I flooded the gates with tons of ways to get an A in the course. It worked, I had fun, I think my students had fun and they got a lot of well-deserved As. More important, my students engaged in the material in more ways than they normally would have.
I’ll say a little bit about my course and then talk about how I implemented lots of assignment choice this semester.
A bit of background
This spring 2022, I taught an introductory survey course on cognitive psychology. I’ve been at Brooklyn College for over a decade and haven’t taught my core area very often. Since summer 2021, I’ve been making up for lost time and decided to develop a suite of open educational resources for introductory cognition. I ran the course for the first time last semester. The modality was synchronous online, so students joined me every week for class lectures. I intended to have a textbook chapter for each week of the course, but I didn’t get that far in writing the textbook (note to self, that I need to finish the book).
In any case, the format for fall 2021 was fairly standard. I had weekly multiple choice quizzes that I posted on blackboard. I had two midterms and final exam. I gave students a few ways to get extra credit. And, I offered some optional writing assignments for students that wanted to dig into the material a little bit more.
The class went off the rails in the middle of the semester. That’s a story for another day, but let’s say an extraordinary amount of unapproved student collaboration occurred. I also learned that I would be teaching the same course in spring 2022 in an asynchronous online format. I knew I wanted to create more interesting assignments for the asynchronous version of the course. So, I made up a bunch of assignments and tested some of them on fall cohort as a second chance to make up for points they may have lost.
Planning for the asynchronous online modality
At Brooklyn College we don’t teach during the January intercession, so I had a bunch of time to plan out how I would convert the course from synchronous online to asynchronous online. Ultimately, this involved creating a ton of content, which took a huge amount of effort. I put all of that content into “learning modules” for each week of the course. All of the learning modules are on the course website, and freely available as an open educational resource.
I structured each learning module into three sections: Read, Watch/Listen, and Engage. The reading section usually linked to a textbook chapter, or any additional readings I wanted to assign. The watch/listen section contained mini-lectures that I recorded and posted YouTube (this part took so much time every week). The engage section contained quizzes and assignments that students could complete each week.
Now comes the fun part, here’s how I flooded the gates with assignment choice to increase engagement with the course material.
Multiple Warp Zones to an A
Given the asynchronous format, I wanted to give students every opportunity to do well in the course. I also wanted to dream up as many ways as I could think of to offer students meaningful ways to engage with the course material. Here’s what I did.
There were 12 learning modules and three exams. The grading rubric is below:
| Assignment | Points | Total |
|---|---|---|
| 12 Weekly Modules | 5+ | up to 60 |
| Extra Credit | see above rules | up to 10* |
| SUPER BONUS | see above rules | up to 40* |
| Midterm 1 | 13.33 | 13.33 |
| Midterm 2 | 13.33 | 13.33 |
| Final Exam | 13.33 | 13.33 |
| 100 |
There were three equally weighted exams, making up 40/100 points. The remaining 60/100 points came from any other assignment in the course.
warp zone 1: Ace the quizzes and exams
Each learning module had a quiz worth 5 points and there were 12 learning modules. So, a student could get 100% on all the quizzes for \(12*5 = 60\) points. If they also aced the exams, then they could get 100/100 for a perfect A+ score.
I view this as the standard fare option for getting through an intro survey course (i.e., pass the quizzes and exams). I think many students are familiar with this structure and some may even prefer it over a course with other kinds of assignments and assessment.
Students always want to know how they will be tested, so I told them that the quizzes they take each week will prepare them for the tests. The exam questions would be like the quiz questions, and some of the quiz questions might even reappear on the exams. I also let them do each quiz twice and allowed them to take the highest grade. It took a really long time to write pools of questions for every quiz and exam. A really long soul-sucking time. And, now I have a respectable test bank for the course (I wrote it using R/exams, which lets me export to Blackboard and pdf, it’s nifty).
 Also, I’m the one who wrote all of the questions, and even though I tried really hard to write good questions, I’m not 100% confident that my tests are good tests of what I’m trying to teach. So, it’s not clear how much test grades reflect student performance versus my performance as an instructor. Plus, my whole philosophy on testing is migrating, so I was looking to add more flare.
I usually require writing in all of my courses, no matter how many students I have. This could be viewed as a form of masochism. For example, I don’t have a TA for my class of 125+ students, and many instructors in my position might not assign writing assignments because they would be overwhelmed by grading.
Assigning multiple weekly writing assignments for a class that size could be viewed as a form of self-torture, and an over-bearing workload for students.
But, I did it anyway
warp zone 2: Everything is optional
As a reminder, students could get up to 60 points from quizzes. The rest of the points came from exams. The second warp zone was to create an alternate way of making up the 60 points. This would give students some choice in how they engaged in course material.
Students already had the choice of taking one quiz per week, and they could get all 60 points that way. To increase choice, I added one or two alternative writing assignments to each learning module. This part was way more fun for me in terms of generating what I considered interesting ways to engage in course material.
For examples, I made short writing assignments on how to read a primary research article, mental imagery, the APA’s apology to people of color, and many more.
Each writing assignment was 5 points, just like a quiz. So, each week students could take a quiz, complete a writing assignment, or both.
I managed the grading by making the assignments short (typically, 100-300 words). I did the grading mostly pass/fail, and students either got full points or not (if they submitted stuff that was way off base). It wasn’t possible to give in-depth feedback on each assignment because of the number of students, but it was possible to give group level feedback.
Not all of my students routinely did the writing assignments, but when they did them, they were really engaged as measured by how awesome their submissions were.
In addition to writing assignments for each learning module, I added on more and more optional assignments. For example, one assignment was to detect and report issues in the textbook I’ve been writing. Perhaps, this was ploy to get students to read the textbook… I also added points for participating in discussion boards, and added more general writing assignments that students could complete by the end of the semester (rather than by the due dates set at the end of each week).
Warp zone 3: Extra credit
At this point, students can get to 60 points by completing any combination of quizzes or assignments. That’s great. But, they still have to take these three exams for 40 points. And, students always want to know if there are extra credit options.
Lucky for them, I love extra credit. I made two tiers of extra credit. If students got to 60 points by completing quizzes and assignments, then any points over 60 was converted to extra credit. The conversion rule was 5 regular points to 1 extra credit. And, I allowed up to 10 extra credits. So, students could complete 10 additional 5 point assignments and get 10 points added onto their final score for the course. That’s a good dose of extra credit, and can make up for a bad showing on a midterm or final.
I love extra credit so much, that in the middle of the semester I made an addendum to the syllabus to describe a super bonus level of extra credit. If students actually did so many optional assignments that they got to the max of 10 extra credits, then I basically made the extra credit rain.
At the super bonus level mark I changed the conversion ratio from 5 to 1, to 2.5 to 1, which doubled the amount of extra from 10 points to 20 points; and, I raised the max extra credit to 40 points, which covers the points students needed to receive from exams.
This is just a fancy way of saying that students could get an A without passing the exams. They would have to pass lots of optional assignments, but IMO, the assignments I created were much more interesting and deserving of an A than the exams.
TLDR
I gave my students lots of ways to pass my course. Many of them tried the engaging and challenging options. I enjoyed what they produced, and I was proud of their scholarship, curiosity, and thoughtfulness. I hope they learned as much from the course as I learned from them.

Cambodia PM orders release of opposition members jailed for 'coup' bid
PHNOM PENH: Cambodian leader Hun Sen ordered the release on Thursday (Nov 14) of dozens of opponents and activists that authorities accused of helping his arch-rival plot a coup.
The arrests were linked to attempts by opposition figurehead Sam Rainsy to return home from France, where he has lived since 2015 to avoid jail for convictions he says are politically motivated.
READ: Indonesia ordered Cambodia's Rainsy barred from flight: Malaysia Airlines
Hun Sen had sent out arrest warrants for Rainsy to neighbouring countries ahead of his planned homecoming of Nov 9.
The Cambodian strongman also beefed up security at the Thai border crossing, and his government has said they will regard Rainsy's return as a "coup attempt".
"The (coup) plot had ill will, but people did not join it," said Hun Sen, who has ruled Cambodia since 1985, on Thursday.
He said more than 70 opposition activists would be released on bail "for the sake of national unity", adding that they had been cheated by Rainsy.
The announcement comes days after Cambodia lifted house arrest restrictions on Rainsy's political ally Kem Sokha, the co-founder of the now-dissolved Cambodia National Rescue Party (CNRP).
READ: Cambodian opposition figure Sam Rainsy arrives in Malaysia
The dissolution of the CNRP paved the way for Hun Sen to sweep a widely criticised election last year, turning Cambodia into a one-party state.
As a result, the European Union started a review of a duty-free tariff scheme for the country's lucrative garment sector. Analysts say the possible removal of the deal is a rare weak spot for Hun Sen.
For now, it remains unclear how Rainsy can return to Cambodia without Hun Sen's say-so.
He had promised to come home on Saturday, Cambodia's independence day, but was blocked from a Thai Airways flight in Paris.
He then flew to Malaysia instead, and on to Jakarta on Thursday morning.


This plugin gives input/output support for the MIDI protocol
and gives the user freedom to control typical parameters like channels, Program Change and Control Change.
The MIDI plugin can be quite powerful used in combination with MIDI devices such as keyboards, MIDI controllers
(like Behringer BCF2000 or KORG nanoKONTROL) or a software audio sequencer like Cubase or Ardour 3.
The usage can vary from fader-to-fader control (the BCF2000 case) to sequence triggering for synchronized
shows (metronome controlled gigs using an audio sequencer)
When you click on the configuration button a window will appear, showing all the MIDI input and output lines
detected.
Each line has three options that can be changed depending on your needs:
The MIDI plugin is the one of the QLC+ plugins supporting feedback. When QLC+ detects a MIDI device with an output line, it will
enable the feedback check box in the Input/Output panel. Please note that output
and feedback are exclusive, so they cannot both be used at the same time.
If your MIDI device supports a return channel, QLC+ can send a visual/mechanical feedback to it.
Devices such as the Behringer BCF2000 support this feature.
This is very useful during live shows to have immediate knowledge of the current state of faders mapped in QLC+.
A small trick that can be achieved with QLC+ is to use feedback as a generic MIDI output line to trigger external controllers/sequencers.
Let's look at some examples:
Starting from version 4.5.0, QLC+ supports the MIDI beat clock
Not to be confused with the MIDI timecode, the MIDI beat clock is
a useful signal to sync BPM-based devices such as a drum machine with your lights controlled by QLC+.
Two special MIDI channels have been mapped in QLC+ to control your Virtual Console widgets
with a beat clock.
Here's a brief explanation of the special channels:
There might be cases where your MIDI device needs some commands to turn into a specific operating mode
The MIDI protocol can handle this through SysEx. These are particular messages to instruct a MIDI device how to behave.
QLC+ can use a XML template to achieve this that can be selected in the MIDI configuration panel.
Here's an example of how a template looks like:
<!DOCTYPE MidiTemplate> <MidiTemplate> <Creator> <Author>Your name</Author> </Creator> <Description>A brief description of that the template does.</Description> <Name>Template name to be displayed by QLC+</Name> <InitMessage>F0 47 00 7B 60 00 04 41 09 00 05 F7</InitMessage> </MidiTemplate>You can create the ones you need and place them in your MidiTemplates folder.
To handle a mix of various MIDI messages (Notes, PC, CC, etc..), QLC+ remaps them into a sequential order.
Following, the channel numbers to be used in the Input Profile editor:
| Channel | MIDI message |
|---|---|
| 1 | Control Change 1 |
| ... | ... |
| 128 | Control Change 128 |
| 129 | NOTE ON/NOTE OFF 1 |
| ... | ... |
| 256 | NOTE ON/NOTE OFF 128 |
| 257 | NOTE AFTERTOUCH 1 |
| ... | ... |
| 384 | NOTE AFTERTOUCH 128 |
| 385 | Program Change 1 |
| ... | ... |
| 512 | Program Change 128 |
| 513 | Channel Aftertouch |
| 514 | Pitch Wheel |
| 530 | MIDI Beat Clock: Start/Stop/Continue |
| 531 | MIDI Beat Clock: Beat |

Retrospective: Full Metal Jacket (1987)
Grade: 89
Another Vietnam War movie? What can be said about the Vietnam War that hasn't been said already? "Full Metal Jacket" answers that question, and demonstrates that there is always room for a great film, even if the genre has already been thoroughly explored.
"Full Metal Jacket" is really two different films, with Matthew Modine's everyman character bridging the gap. The first half has several dozen marine recruits undergoing basic training, under constant verbal and physical abuse from a tough-as-nails drill sergeant (R. Lee Ermey, who should have won Best Supporting Actor, even if he was a marine drill sergeant in real life). His favorite target is fat, slow recruit nicknamed Gomer Pyle (Vincent D'Onofrio). Those who are considering joining the marines should see this film. It may change their mind!
Only three mild criticisms about the first half, which is superior to the second half. Out of the large number of marine recruits, only four (Joker, Snowball, Pyle and Cowboy) have speaking parts. Did the writers think we would get confused with too many characters, or was the producer unwilling to pay extras to speak? Also, Modine frequently does a John Wayne impersonation, which is not very good! Finally, Pyle has a weird character turn that doesn't seem likely despite all the abuse and brainwashing he has received.
The second half of the film has Modine in Vietnam, covering the war first as a journalist and then as a soldier. The early scenes of this second half are outstanding, but when Modine finally sees action the film declines slightly, though still excellent. War is hell, but in this case not quite as interesting.
One observation is that the American soldiers have great respect for the North Vietnam soldiers, but contempt and bitterness towards the people of South Vietnam. This may be due to its corruption, depicted through extended scenes of negotiations with prostitutes, or the notion that South Vietnam was not grateful for the "assistance" of Uncle Sam. Actually, given scenes of a soldier in a helicopter machine-gunning every Vietnamese he sees, of any age or gender, it is clear why the South Vietnamese weren't so grateful!
Not the greatest war movie ever (I still favor "All Quiet on the Western Front") but probably one of the best Vietnam movies ("Apocalypse Now" was overlong and lacked necessary focus.) and the best basic training movie.

A rain garden is a constructed area which collects rainwater from roofs, pipes and driveways etc. During monsoon, a large quantity of rainwater is wasted as most houses do not have any rainwater collection mechanism installed and is lost in drains. Common uses of wastewater from rain gardens include using it for washing cars, utensils and other activities which require water other than consumption. A rain garden also ensures that there is no additional pressure on the city’s sewage system as the rainwater is collected instead of going into the drainage system.
Drinking water is also wasted by many of us at homes, even if unintentionally. Often half-filled water bottles and glasses are emptied by us casually, only to fill them with freshwater. Because of this daily habit of ours, several litres of water is wasted over a period of time. Make it a habit to empty your half-filled bottle or glass over a plant, or use it to wash utensils or any other household items. It must become a habit to not waste any amount of water, no matter how small the quantity. Every drop of water counts.
Just kidding, wanna know some facts about waste water?

Navy gears up for relief ops as Cyclone Maha approaches Gujarat coast
Four warships of the Western Naval Command have been loaded with HADR materials like food packets, water, medical supplies and other essential commodities
by PTIAs Cyclone Maha over East-Central Arabian Sea intensified into an 'Extremely Severe Cyclonic Storm', the Navy said on November 5 its western command has prepared for humanitarian and disaster relief (HADR) operations along the Gujarat and north Maharashtra coast.
Four warships of the Western Naval Command have been loaded with HADR materials like food packets, water, medical supplies and other essential commodities.
Naval units of Gujarat Naval Area are ready with emergency response teams equipped with underwater diving equipment and inflatable boats. Additionally, naval aircraft and helicopters are also on standby, it said.
Naval authorities in Gujarat are in constant liaison with civil authorities to ensure seamless coordination, it added.
Maha is expected to make landfall near Veraval by the night of November 6 with winds up to 35-40 knots.
Rough to very rough sea conditions are likely to effect East-Central Arabian Sea and heavy rain with thunder and lightning is expected to effect south Gujarat and north Maharashtra areas.Special Thursday Expiry on 10th 7th Nov

#include <db_cxx.h>typedef void *(*db_malloc_fcn)(size_t); void DbInfo::set_malloc(db_malloc_fcn);
Set the malloc function used by the Db methods.
The DB_DBT_MALLOC flag, when specified in the Dbt object, will cause the Db methods to allocate memory which then becomes the responsibility of the calling application. See Dbt for more information.
On systems where there may be multiple library versions of malloc (notably Windows NT), specifying the DB_DBT_MALLOC flag will fail because the Db library will allocate memory from a different heap than the application will use to free it. To avoid this problem, the malloc function should be set to point to the application's allocation routine. If malloc is not explicitly set, it will be used to allocate the memory returned when the DB_DBT_MALLOC flag is set. The malloc method must match the calling conventions of the malloc(3) library routine.


NEVER BEEN KISSED (20th Century Fox) Starring: Drew Barrymore, David Arquette, Michael Vartan, Leelee Sobieski, Jeremy Jordan, Molly Shannon, John C. Reilly. Screenplay: Abby Kohn & Marc Silverstein. Producers: Sandy Isaac and Nancy Juvonen. Director: Raja Gosnell. MPAA Rating: PG-13 (adult themes, profanity, drug use) Running Time: 104 minutes. Reviewed by Scott Renshaw.
I'm willing to forgive NEVER BEEN KISSED many of its failings because, for all practical purposes, it's a fantasy. I can over look the irony of a film about an adult returning to interact with teenagers which portray teens the same inane way adults usually think of them. I can let it slide that the tone is terminally bubbly when a touch of venom might have helped. I can even shrug my shoulders at the notion that Drew Barrymore was ever a spat-upon teen wretch. Sometimes a romantic comedy can get away with being ridiculous as it strives to pull us into its wish fulfillment.
Our high-concept premise finds 25-year-old Chicago Sun-Times copy editor Josie Geller (Barrymore) offered her first real reporting assignment: going undercover as a high school student. The assignment brings mixed emotions for Josie, a brainy high school outcast still smarting from her adolescent ostracism. As she begins her quest for a story, Josie finds herself drawn back into the world of the "smart kids" at South Glen South High School, including her new friend Aldys (Leelee Sobieski). That's before her editor (John C. Reilly) demands that Josie get in with the in crowd, and before Josie's arrested adolescent 23-year-old brother Rob (David Arquette) also re-enrolls and helps turn the one-time "Josie Grossie" into a potential prom queen.
NEVER BEEN KISSED does a serviceable job of telling Josie's story, exploring how a woman comes to terms with the person she was and is. If only the script had shown as much dilligence with the other elements. Arquette's character is potentially even more interesting than Barrymore's -- a jock who peaked at 18 trying to re-live his glory days -- but it's generally watered-down and ignored. The romantic angle between Josie and her English teacher (Michael Vartan) is half-heartedly developed, muddles the entire point of the story -- are we supposed to believe that Josie was incapable of finding true love before re-creating her traumatic youth? -- and builds to a spectacularly clumsy conclusion. Most depressing of all is a ghastly device which finds Josie wearing a miniature camera, contributing nothing more to the story than pointless cutaways to Josie's co-workers gaping or cringing in embarrassment.
There's plenty to gape and cringe at as Barrymore plays Josie. You've got to admire how gamely Barrymore subjects herself to humiliating situations, but she's all wrong for the lead role in her first feature as executive producer. Even the marketing people at Fox realize that she's most appealing as a sweet object of desire, making the central image in the film's publicity a photo of Barrymore smiling coquettishly with knee drawn up to her chest. As a star carrying this film, she looks out of her depth. It's slightly embarrassing watching her play the professional Josie as a tightly-coiffed fussbudget correcting everyone's grammar and usage; as implausible as she may be as a high school senior, she proves even more implausible as a grown-up.
 There simply isn't a nuance to the material that director Raja Gosnell manages to capture, not a moment of sincere emotion, nothing that doesn't look like it wouldn't exist if not for other movies about kids in high school. When the script manages to work in a wise observation -- like the idea that one popular person in high school can dictate who's cool and who's not -- it feels like someone tripped over it accidentally. NEVER BEEN KISSED is most certainly a fantasy for anyone who ever felt like the quintessential high school outsider, but the film-makers are living in a fantasy world if they think that's all they need to deliver.

James Clayton Cholewinski-Boy arrested in American Airlines alleged se
TULSA, Okla. — A Utah man accused of groping another passenger on a Salt Lake City-bound American Airlines flight that diverted to Tulsa for his arrest has been charged with abusive sexual contact.
The man, identified in court records as James Clayton Cholewinski-Boy, 32, was charged by federal prosecutors Friday.
An FBI agent said in an affidavit that Cholewinski touched the arm of a woman next to him Tuesday, and she pushed his hands away. The woman said Cholewinski then grabbed her crotch, she pushed his hand away and told him to stop, at which point he held up his hands and said he was sorry.
Flight attendants moved the woman and her daughter to different seats. The American Airlines flight from Charlotte, North Carolina, to Salt Lake City made an unscheduled stop in Tulsa, where Cholewinski was arrested. Airport police charged him with public intoxication, then turned the case over to the FBI, which filed the sexual contact complaint.
Cholewinski lives in Murray, Utah, according to federal officials, who believe he also goes by the name Cholewinski-Boyd.
It wasn’t immediately clear if the man had a lawyer who could comment on his behalf. Tulsa city jail records indicate that Cholewinski was released Wednesday. A jail officer said he was released on a promise to appear in court on the charges.
In April, an agent based in Los Angeles said the FBI received 63 reports of sexual assault on airline flights in fiscal 2018, up from 38 cases in fiscal 2014. The agent, David Gates, added “It’s safe to say that many incidents occur that are not reported.” He said most involve unwanted touching.

jQuery outside events: Why trigger an event on something, when you can trigger it on everything else?
With jQuery outside events you can bind to an event that will be triggered only when a specific “originating” event occurs outside the element in question. For example, you can click outside, double-click outside, mouse-over outside, focus outside (and over ten more default “outside” events). Also, if an outside event hasn’t been provided by default, you can easily define your own.
Note that this was previously known as the “jQuery clickoutside” plugin.. but, hey—it’s pretty amazing what a an awesome idea and few more lines of code can do!
- Release v1.1
- Tested with jQuery 1.4.2 in Internet Explorer 6-8, Firefox 2-3.6, Safari 3-4, Chrome 4-5, Opera 9.6-10.1.
- Download Source, Minified (0.9kb)
- Follow the project on GitHub project page or report a bug!
- View Full Documentation
- View Unit Tests
- Examples: click outside, double-click outside, mouse-over outside, focus outside
Supported “outside” events
By default, these “outside” events are supported: clickoutside
, dblclickoutside
, focusoutside
, bluroutside
, mousemoveoutside
, mousedownoutside
, mouseupoutside
, mouseoveroutside
, mouseoutoutside
, keydownoutside
, keypressoutside
, keyupoutside
, changeoutside
, selectoutside
, submitoutside
.
Note that each “outside” event is powered by an “originating” event (see the complete list). Only when the originating event is triggered on an element outside the element to which that outside event is bound will the bound event be triggered.
A basic usage example
Let’s say you have a modal dialog. In addition to a standard “close dialog” button, you want the user to be able to click anywhere outside the dialog to close it. Instead of creating a background overlay that the user must click on, you can just use this plugin!
// Hide the modal dialog when someone clicks outside of it. $("#modal").bind( "clickoutside", function(event){ $(this).hide(); });
Note that you can also utilize the event.target
property, which references the actual element clicked, in your event handler logic. This may be useful if you want to constrain the ‘outside-ness’ of the click to certain elements or containers.
And of course, this same approach works for all “outside” events. See the working examples for more information.
How it works
jQuery outside events are made possible by event delegation. Because events in jQuery bubble up the DOM tree, a catch-all event handler bound on document can be used to see when and where a specific event has been triggered.
When an “outside” event is bound on one or more elements, those elements are added into an internal array and an event handler for the corresponding “originating” event is bound on document. For example, when a “clickoutside” event handler is bound on some divs, the plugin binds a “click” event handler to document.
After that point, whenever an element on the page is clicked, the event will propagate up the DOM tree to document, where the document click event handler will execute. Since that handler can use event.target
to know on which element the event was triggered, it can then iterate over all elements in the aforementioned internal array, triggering the custom “outside” event on all elements that aren’t equal to, or a parent of, the triggering element.
Now, whenever an event is triggered on an element, that event’s .target
property refers to the element on which the event was triggered. Normally, since events bubble, a bound event handler might not be on the triggering element, but instead might be on one of its ancestor elements, so this makes sense for most events. Of course, in a situation like this, where the custom “outside” event is triggered directly on the element to which it is bound, event.target
and this
will be the same value inside the event handler.
Now, because the originating event is, by definition, being triggered on an element that is outside the element on which the custom “outside” event is triggered, it seems most useful to set event.target
to be the element on which the originating event was triggered, which, if you remember, was available in the document-bound originating event handler.
Fortunately, the special events API in jQuery 1.4.2+ makes this very easy, and it’s just a few lines of code (see here and here) to override any event
object properties for a custom event.
While this explanation might have been a little long-winded, this really is a fairly simple example of a jQuery “special event” plugin, so if you want to write one of your own, feel free to take a look at the fully commented source code.
Ok, back to usage
Well, there’s little else to say. Technical explanation on event bubbling aside, this plugin is really quite straightforward. Be sure to check out the click outside, double-click outside, mouse-over outside and focus outside working examples to see it in action, and work from there!
If you have any non-bug-related feedback or suggestions, please let me know below in the comments, and if you have any bug reports, please report them in the issues tracker, thanks!
Special thanks to Jeff Robbins for the original “clickoutside” plugin idea, and David Petersen for the “focusoutside” idea that got me thinking about converting this into a more general “outside events” plugin!

Liverpool midfielder Fabinho ruled out until 2020 with ankle injury
Liverpool midfielder Fabinho will be out for more than a month after suffering ankle ligament damage during this week's Champions League clash with Napoli.
The Brazilian, who has this season established himself as a first-choice pick for Jurgen Klopp's Premier League leaders, was substituted after just 18 minutes of the 1-1 draw at Anfield.
The Reds have now announced that the 26-year-old will play no part in their congested run of 10 games between now and the end of December.
A club statement read: "Liverpool can confirm Fabinho suffered ankle ligament damage during the Champions League encounter with Napoli in midweek.
"Further assessment on the injury has discovered Fabinho will be out of action until the new year.
"The Brazilian will begin a rehabilitation programme with the Reds' medical team at Melwood as he works his way back to full fitness."

val status: Status?
For bank accounts, possible values are new
, validated
, verified
, verification_failed
,
or errored
. A bank account that hasn’t had any activity or validation performed is new.
If Stripe can determine that the bank account exists, its status will be validated
. Note
that there often isn’t enough information to know (e.g., for smaller credit unions), and
the validation is not always run. If customer bank account verification has succeeded,
the bank account status will be verified
. If the verification failed for any reason,
such as microdeposit failure, the status will be verification_failed
. If a transfer sent
to this bank account fails, we’ll set the status to errored
and will not continue to send
transfers until the bank details are updated.
For external accounts, possible values are new
and errored
. Validations aren’t run
against external accounts because they’re only used for payouts. This means the other
statuses don’t apply. If a transfer fails, the status is set to errored
and transfers
are stopped until account details are updated.

NModelRS is a remote
stepper for NModel, enabling model-based testing of implementations in other
languages than C#, in particular Java.
NModel is a
model-based testing and analysis framework for model programs written in C#. It
is explained and used in the book Model-based Software Testing and Analysis with
C# by Jonathan
Jacky, Margus Veanes, Colin Campbell, Wolfram Schulte, Cambridge University
Press, 2008. NModel is free open source available at http://nmodel.codeplex.com/.
For a short introduction to NModel look here.
Having a C#
model of a system you can test an implementation (IUT) of the system if you
have a test harness (stepper) that can execute the actions against the
implementation. NModelRS provides a RemoteStepperProxy
(RSP) you can use with NModel’s conformance tester (CT), allowing you to write
test harnesses in other languages and to execute them on other machines. The RSP
communicates with a remote stepper in the test harness over TCP and receives
asynchronous observations over UDP
NModelRS
provides a Java component with a Remote
Stepper and an Observer, but also a File Stepper that can replace the Remote
Stepper without changing the Test Harness. The File Stepper is used to execute
test suites generated by NModel’s Offline Test Generator (OTG) in the test
harness
Or you can
use the CT tool to execute the test suite
Microsoft
has used Model-Based Testing for years and NModel is an offspring of the
development of Spec
Explorer 2010 for Visual Studio 2010.
Grieskampf
has told the Spec
Explorer Story including the relation to NModel.
The
research paper Multi-paradigmatic
Model-Based Testing describes lessons learned in applying MBT at Microsoft
and introduces the theory behind the tool.
The Spec
Explorer Team Blog explains MBT
in few words and an enticing diagram
General
advice on MBT can be found in the book Practical Model-Based Testing: A
Tools Approach by Mark Utting and Bruno Legeard, Morgan-Kaufmann 2006.
Chapter 10 presents The ATM Case Study; (A control-oriented model in UML)
using an ATMExample
developed by Russell C. Bjork for a university course on Object-Oriented
Software Development.
This ATMExample
comes with a Java implementation of a simulated ATM. I have modelled the ATM in
C# and made a Java test harness being presented here.

New host, new toys.
2006 December 10th by todd anderson
I recently switched from my current host, to a dedicated server and i couldn’t be happier.
I was fairly happy with my current shared-hosting plan ( though reading Aral’s problems started to make we think twice ), but i have increasingly wanted more out of an online server that my current host just couldn’t provide. So i purchased a virtual private server from Westhost. So far, i have had no complaints, they are attentive to any pointless questions i may have, and the forums are an endless supply of knowledge. I have yet to move all my content from my current host over, so that’s a task i don’t look forward to…

I have to say, the main ingredient that caused this push to a vps is Red5 ( if you are unfamiliar with red5, there are more links at the bottom of this post ). I have been checking-out the source and not touching Red5 since release 0.4, so i was in good shape to know nothing about it when rc0.6 came out… enter Chris Allen into our Boston office and he gives a great presentation onRed5, sparking my interest to really buckle down and play with it. If you or your company are at all interested in what Red5 can provide for your business, i wouldn’t hesitate to get in touch with Chris.
Things were touch and go a little with running Red5 on my new server ( again big-ups to Ash ), but i eventually abandoned running apps on a built Red5 server and switched to deploying it under Tomcat. Oh boy! No problems yet and i am like a kid in a candy store. And with the current development on closing ghost connections, i’m ecstatic. Their API is rock solid, can only get better, and i am finally thinking in Java on my own after reading numerous books and doing countless tutorials.
I’ve been playing with AS3, Java and Red5 lately and have something up and running, but i’m re-working the code and rebuffing the appearance… hope to have it up soon. I may throw up some directions and trials and tribulations of setting up the server, if anyone is interested. Until then –

public java.awt.image.Raster getData()
The returned Raster is semantically a copy. This means that updates to the source image will not be reflected in the returned Raster. For non-writable (immutable) source images, the returned value may be a reference to the image's internal data. The returned Raster should be considered non-writable; any attempt to alter its pixel data (such as by casting it to WritableRaster or obtaining and modifying its DataBuffer) may result in undefined behavior. The copyData method should be used if the returned Raster is to be modified.
