BUT I'M A CHEERLEADER (director/writer: Jamie Babbit; screenwriter: Brian Wayne Peterson/based on a story by Ms. Babbit; cinematographer: Jules LaBarthe; editor: Cecily Rhett; cast: Natasha Lyonne (Megan ), Clea DuVall (Graham), RuPaul Charles (Mike), Cathy Moriarty (Mary Brown), Eddie Cibrian (Rock), Bud Cort (Peter), Mink Stole (Megan's Mom), Melanie Lynskey (Hilary), Katharine Towne (Sinead), Dante Basco (Dolph), Brandt Willie (Jared); Runtime: 84; Lions Gate Films; 1999)
Reviewed by Dennis Schwartz
The simple message this one-note film envisions, is that one should never be who they are not. To show how ridiculous the Fundamentalist Christian family value adherents have gone in trying to force their beliefs down everyone's throats, the film shows what they advocate can be cruel to those who are caught in their moral trips. The debut feature of Jamie Babbit is unabashedly awkward and to make matters worse, she can't get the cast to stop mugging for the camera. The comedy was lame, the characters were not interesting, only the idea was good if it could have been developed into a story with more dimensions than the one it belabored.  There was not enough of a story for it to be released as a movie. It was painful to watch this kind of kitsch for 80 or so minutes, which seemed to drag on for a hellish eternity. It is just as tortorous watching this film as it probably is going through such an indoctrination program.
A typical high school cheerleader in a suburban setting, the sweet, innocent Megan (Natasha Lyonne), is driven home by her handsome high school football player boyfriend Jared (Brandt Willie) to find her family and friends gathered in the living room. They talk her into going to a rehabilitation camp for homosexuals aptly named True Directions by presenting her with the evidence of her lesbianism - her vegetarianism, her Melissa Etheridge poster, and her lack of responsiveness to her boyfriend's tongue kisses (while kissing him, she is looking longingly over at the cheerleaders). Megan, who just wants to be normal, is trapped by her self-righteous parents (Mink Stole & Bud Cort), the dullness of the people in her suburban community, and with the community's biblically defined gender roles offering no room for another viewpoint.
The camp offers a 5-step program to rid one of homosexuality. The camp director, Mary Brown (Cathy Moriarty), is the rigid martinet who is a walking cliché.  He is also the groundskeeper making sexual gestures with his chain-saw, who camps it up to the point of going over-the-top, losing all proportion for his character as being anything but a cartoon figure.  All the boys in the camp were sorry sights, offering neither comedy nor concern for them. While the girls were all forgettable types, except for the one rebel who Megan will fall for, Graham (Clea DuVall). Clea is the only one in the film who belonged in this film and made the most of her role, making it believable as the rich bitchy girl who knows damn well that she's a lesbo, but also knows that if she doesn't go through with this farce of a rehab program, her parents will take away the trust fund she stands to inherit.
The absurdity of the film is highlighted in its loud set designs, as the girls are overwhelmed with garish pink and tangerine colored outfits and room furnishings, while the boys are furnished with this hideous bright blue color. The other absurdity is in how artificial the planned steps are and how meaningless it is to graduate from a program such as this one. Of course, Megan, who wasn't gay to begin with, realizes that maybe she could be gay as a result of this treatment.
This is not a good campy film, and to the bargain, after trying to get laughs for the first half of the film, it then starts to take itself seriously. But the theme is so absurd, that there really is no message that can be delivered. Everything about it is strained. Natasha Lyonne was miscast, she couldn't pull off what was required of the role, to be someone who awakens in a subtle way to who she really is. She seemed to be going for the hammy sweetness she thought her role required and when the comedy part of the film was over and she had hot pants for Graham, there was no spark on the screen to give the affair any life. It all seemed manufactured, leaving the film telling its joke to an audience they believe will be sympathetic. The problem with that is, the one-note joke ran dry a long time ago.
I just couldn't wait for the film to end. If you are going to make a campy B movie, then it takes more than crudeness and over-the-top performances to make it funny. I'll take my campy film with no pretenses to art ... let it be a film that is bitingly hilarious (OK, just funny will do).

Return the hash of an attachment.
Given the owner, the parent folder and and attach name get the attachment hash.
- Parameters
-
| int | $owner | The owner_id |
| string | $hash | The parent's folder hash |

The DAV browser is instantiated after the auth module and directory classes but before we know the current directory and who the owner and observer are. So we add a pointer to the browser into the auth module and vice versa. Then when we've figured out what directory is actually being accessed, we call the following function to decide whether or not to show web elements which include writeable objects.
It only disable/enable the visible parts. Not the POST handler which handels the actual requests when uploading files or creating folders.
- Todo:
- Maybe this whole way of doing this can be solved with some $server->subscribeEvent().

No it is not because having more black pixels on a computer monitor will reduce the energy used by the monitor. It's actually because of the "All Blacks", the national Rugby Union team of New Zealand.
Then again everyone looks better in black - no matter what they say, black will always be the new black.

NAF neutralises ISWAP leaders, destroys meeting venue
by The Eagle OnlineThe Nigerian Air Force has neutralised some Islamic State of West Africa Province leaders and destroyed their meeting venue at Jubillaram in the Northern part of Borno.
Air Commodore Ibikunle Daramola, NAF Director of Public Relations and Information, made this known in a statement on Wednesday in Abuja.
He said the operation was conducted on Tuesday through the Air Task Force of Operation LAFIYA DOLE.
“The operation was executed yesterday, November 19, sequel to intelligence reports indicating that some top ISWAP leaders had assembled for a meeting at a compound within the settlement, which they also used to store some of their logistics supplies.
“Accordingly, the ATF dispatched a Nigerian Air Force Intelligence, Surveillance and Reconnaissance platform as well as fighter jets to attack the location.
“Overhead the target area, several terrorists were observed around some buildings in the middle of the settlement.
“These fighters were neutralised in successive strikes by the attack aircraft as they attempted flee the location.
“The air strikes also led to the destruction of some terrorists’ structures, including one of their logistics stores, which was seen engulfed in flames,” he said.
Daramola said the NAF, operating in concert with surface forces, would sustain its efforts to completely destroy all remnants of the terrorists in the North East.

NAB profits dive amid banking sector scandal fallout
SYDNEY: National Australia Bank announced on Thursday (Nov 7) that its profits fell more than 13 per cent in 2019, the latest in a string of poor results for the country's banks as they address years of rampant malpractice.
A damaging industry scandal has forced NAB and Australia's other major banks to allocate billions of dollars to repay customers for unfair fees and dodgy financial advice.
The Melbourne-based NAB said its net profit in the year to Sep 30 had fallen to Aus$4.7 billion ($US3.23 billion), in what CEO Philip Chronican described as a "very challenging" year that required "significant actions to deal with past issues".
A lengthy Royal Commission that wrapped up in February found banks had charged fees to dead people, charged fees for no services at all, used aggressive selling tactics and provided poor advice that led to significant financial upheaval for clients.
NAB was singled out for especially harsh criticism, resulting in the departure of the firm's CEO and chairman.
The company has set aside more than Aus$2 billion to repay customers and has a team of nearly 1,000 people dedicated to its remediation efforts.
"We are determined to move forward by fixing issues of the past and taking actions to meet customer and community expectations," Chronican said in a statement.
"A gap remains between where we are today and where we need to be for customers, but we are making progress."
The bank has cut its dividend to shareholders by 16 per cent compared to 2018, bringing the full-year divided to Aus$1.66 per share.
The announcement comes just days after Westpac bank said its profits had fallen 16 per cent in fiscal 2019, while the ANZ bank reported late last month a seven per cent drop in profits for the same year.

(October 3, 2015)
In this post I am going to talk to you about how a piece of software that is not as gooey as you would expect but plays a big role when managing source code versions. It is also open source, meaning it is free to use! It is called version control. Version control is simply the process of tracking and managing file changes over time. But, why use version control for your source code? Well, have you ever had code you were working on and found out it did not quite work only to wish you could go back to a stable version? Or what about when each member of your team is working on several files and everyone has to consolidate their work back to the original how would you track that? What about if you wanted to know who wrote the code, what they changed and why they changed it? Implementing version control will help solve all of these issues and more.
Ok so now you understand version control so what is this genius piece of free software that will help track all of this? It is called Git. Developers use Git because of its simple and fast design. Although there are some graphical user interfaces (GUI) clients available, in its true form Git runs purely through command line interface or interpreter (CLI). The CLI is a way for you to navigate and manipulate your systems files through text commands by terminal/console. Git allows you to check and progress changes to your files. It consist of three phases: the working phase, the staging phase, and the commit phase. Afterwards you are able to do a pull/merge request.
In the working phase you create a copy of the file on your local drive and then create a new branch (subdivision) to make your changes. Once you finish your editing you move to the staging phase where you add the file to be tracked or staged by Git. Next, your file moves to the commit phase where you finalize and commit (save) the changes. Last, you send your files back to the remote location, such as GitHub; more about that later. You then create a pull request for your code to be reviewed and approved to be merged with the original source.
GitHub is a great complementary source where people are now able to host their source files into repositories on the cloud.GitHub provides some great advantages when it comes to version control and collaboration. One reason is that your code is hosted remotely so if your computer dies you will be able to retrieve your files to the most recent stable version. Another reason is that it allows for your code to be forked (copied) and to be worked on by anyone allowing for growth and improvements on the project. In addition, it allows for code review and collaboration before the changes are merged (consolidated) with the original source file.
I hope you have taken a basic understanding on what the purpose of Git is and how it helps with version control. Also, what a supplementary tool GitHub is to Git. Remember, version control helps with who, what, why and recovery of files over time.

Background reading for modern asset pricing theory
Pricing models for financial derivatives require, by their very nature,
utilization of continous-time stochastic processes.
Three major steps in the theoretical revolution led to the use of advanced
mathematical methods:
1. The arbitrage theorem gives the formal conditions under which
"arbitrage profits" can or cannot exist. It is known that
if asset prices satisfy a simple condition, then arbitrage cannot
exit. This was a major development that eventually permitted
the calculation of the arbitrage-free price of any "new" derivative
product.
Black Scholes model: used the method of arbitrage free pricing. But the
paper was also infleuntial because of the technical steps introduced in obtaining
a closed form formula of option prices.
Using equivalent martingale measures was developed later. This method
dramatically simplified and generalized the original approach of Black and Scholes.
With these tools, a general method could be used to price any derivative product.
The value of derivatives often depends only on the value of the underlying asset, some interest
rates, and a few parameters to be calculated. It is significantly easier to model such an instrument
mathematically than, say, to model stocks.
Some other books:
- Hull 93
- Jarrow and Turnbull (96)
- Ingersoll and Duffie (87 and 96)
Derivative securities are financial contracts that "derive" their value
from the cash market instruments such as stocks, bonds, currencies and commodities.
A financial contract is a derivative security, or a contingent claim if its
value at expiration date T is determined exactly by the market price of the
underlying cash instrument at time T.


For those who know me, they can verify that I do not like crowds. And I certainly do not care to share my shower and toilet with 2 500 revellers! So it was with some trepidation that my colleague, Richard, and I headed off to Swellendam to cover the Up the Creek Festival on the Breede River. We thought that if we arrived early on Friday morning we would have the pick of the camping area, under a shady tree, to protect us from the blistering heat. To our dismay, we were met by a sea of tents with not even a tiny bit of shade available. So we opted for convenience and chose a spot right next to the ablution block. Note to self: arrive early on Thursday next time!
After setting up our tent we headed to the river to cool off. The temperature by this stage was well into the 30s. Already the river was filled with all sorts of floating paraphernalia, either bobbing next to the stage or parked under a massive awning that had been constructed in the middle of the river. On the paraphernalia were friendly and considerate people of all shapes and sizes, some with their children, just letting their hair down, escaping from reality for 4 days and having a ball. Heee ha! As the day progressed we discovered that in fact we had not chosen such a bad spot for our campsite after all. Being right next to the outdoor showers meant that it provided us with instant relief, however brief, from the now unbearable 40 degrees. The other added benefit, and I know I am going to sound like a bit of a pervert, (but it was mainly due to Richard's encouragement), was the continual stream of
lovely ladies taking lengthy showers to cool off. We had many a male offering us money for our space. With my strong entrepreneurial spirit, I must admit, I was tempted.
As the sun descended behind the hills, the party began to change gear. The sheer energy of the music took me somewhat by surprise. I sort of expected a more chilled out vibe. Looking around me however, I noticed that there were far younger people around, compared to myself, which would explain why I didn't recognise any of the music. Although not all the music appealed to me, I was not to be outshone by the younger crowd and soon got into the spirit of things. What I did appreciate most about the bands was their raw energy, the rapport they created with the crowd, and the obvious talent they possessed. It was quite an eye opener and put my support firmly back in SA music. My favourites were December Streets, Jeremy Loops, Desmond and the Tutus, and The Nomadic Orchestra (which is a five-piece instrumental band that got one's foot a tapping). Although I did not get to listen to all the bands, one thing is certain - for the 500 bucks one pays for the four days and three nights of pure entertainment by over thirty of SA's top musicians, is a pure give away. So, to the organisers, a resounding WELL DONE for getting all these artists together, and credos on the sound quality, too. Absolutely first class!
Just when I thought I had had as much fun as I could, it was time for the Anything That Floats competition. This was a celebration of the creative spirit. Anything and everything that could float, and even some that couldn't, took part in this awesome competition. The winners of The Best Float, The Float with the Mostest, and The Most Romantic Float were treated to an array of prizes to reward their grand efforts. As for the rest of the festival, I overheard a fellow reveller put it in a nutshell when saying she felt quite exhausted by the continual entertainment and was completely overstimulated by the kaleidoscope of colour, music, people and activities. The glow on her face indicated it was a pleasant weariness.
Thumbs up to Reliance (reliance.co.za), and Greenpop (greenpop.org), who partnered in greening the festival by calculating and offsetting their carbon footprint, as well as implementing various recycling activities. A local company, Bontebok Recycling, worked tirelessly at all sorts of hours, managing the collection, separation and removal of waste. Trashback (trashback.org) also had an innovative program that rewarded people for rubbish that was brought in.
Would I go there again? Absolutely! Would I camp in the same eye candy spot? No! I would find a more peaceful spot (if that's possible) on the outer regions of the camping ground. I would also not bother to bring my own food as the food stalls are of a high standard, wellpriced and cater to all culinary needs. Less stuff to pack, too. Any extra space needs to be dedicated to ice. And beers.
If I could offer any caution, it would be that parents should be aware that their children will be exposed to some rather hectic language by some of the bands and the MCs. That's just me... older, and all that!
In a quieter moment, (not sure when that was!), I wondered where it had all began.
On returning home I logged on and went to upthecreek.co.za and found that it was inspired and created by Annie Sowden who says in her blog, "A LIFE magazine, a 40th birthday party and a riverside camp called Up the Creek. That's how it all started." She had read an article on the 1969 Woodstock festival in a LIFE magazine and when asked what the highlight of the festival was, one reveller simply replied, "Jimi Hendrix at dawn." This was the inspiration she needed to organise a friend's 40th birthday party at Up the Creek camp. With three bands playing on the stoep of the farmhouse, "I got my Jimi Hendrix-at-dawn moment," says Annie. "Four months later, in January 1991, Up the Creek Festival debuted with 150 paying punters. 22 Years on... and Up the Creek is still one long weekend of rock 'n roll revelry."
22 Years! Well that explains how well organised the event is. Many years' experience! It also explains all the guys I saw who were older, die-hard looking types. Older than me, I might add. They're addicted and who can blame them?

This version of SAGE uses a shared collection of cards across multiple classrooms. Some of these cards may have been created by other teachers.


Quick facts
- The average adult needs anywhere from 7-9 hours of sleep every night
- Sleeping less than this needed amount will result in an accumulation of sleep debt
- To eliminate your sleep debt, you need to sleep more than your needed amount, hour for hour.
- Because of sleep debt, you may get 8 or even 9 hours of sleep, and still feel tired.
Example
Let's assume a college student, who needs 8 hours a night, sleeps according to the hours above. If the student needs 8 hours a night, their total sleep need is 56 hours a week. However, in this hypothetical week, the student got 48 hours. This means that the sleep debt accumulated this week was a total of 8 hours, or a whole day's worth of sleep.
Here's the graph for this person's sleep debt:
Sleep Debt Studies
Sleep debt has been examined in a research setting. First, we will look at the Multiple Sleep Latency Test (MSLT) and then we will look at the 14 hour study. For MSLT, researchers placed participants in a sleep environment (dark room with a bed) and measured how long that person took to fall asleep.  Even though some of the test points were in the middle of the day, participants with a lot of sleep debt could fall asleep almost instantly. Those that were well rested would take a long time to fall asleep, if they fell asleep at all. Here is an example of some MSLT results.
There's an inverse relationship between sleep debt and sleep latency.
The 14 Hour Study
The 14 hour study involves having participants confined to a dark room with a bed for 14 hours every night. The amount they sleep is then recorded. Because these people have no other things to do besides sleep, the actual amount of sleep they need is revealed. Not only that, but sleep debt becomes incredible clear. Here are some example results from a 14 hour study.
The sleep debt this person had is highlighted in green. As you can see, the sleep debt is eliminated with extra sleep, and then the usual amount of needed sleep (about 7.5 hours) is all the person can sleep, even though he/she is confined to a room for 14 whole hours.

Vitess has some requirements on how MySQL should be configured. These will be detailed below.
As a reminder, semi-sync replication is highly recommended. It offers a much better durability story than relying on a disk. This will also let you relax the disk-based durability settings.
MySQL versions supported are: MariaDB 10.0, MySQL 5.6 and MySQL 5.7. A number of custom versions based on these exist (Percona, …), Vitess most likely supports them if the version they are based on is supported.
The main my.cnf
file is generated by
mysqlctl init
based primarily on
$VTROOT/config/mycnf/default.cnf.
Additional files will be appended to the generated my.cnf
as specified in
a colon-separated list of absolute paths in the EXTRA_MY_CNF
environment
variable. For example, this is typically used to include flavor-specific
config files.
To customize the my.cnf
, you can either add overrides in an additional
EXTRA_MY_CNF
file, or modify the files in $VTROOT/config/mycnf
before
distributing to your servers. In Kubernetes, you can use a
ConfigMap to overwrite
the entire $VTROOT/config/mycnf
directory with your custom versions,
rather than baking them into a custom container image.
When a new instance is initialized with mysqlctl init
(as opposed to
restarting in a previously initialized data dir with mysqlctl start
),
the init_db.sql
file is applied to the server immediatley after executing mysql_install_db
.
By default, this file contains the equivalent of running
mysql_secure_installation,
as well as the necessary tables and grants for Vitess.
If you are running Vitess on top of an existing MySQL instance, rather than using mysqlctl, you can use this file as a sample of what grants need to be applied to enable Vitess.
Note that changes to this file will not be reflected in shards that have already been initialized and had at least one backup taken. New instances in such shards will automatically restore the latest backup upon vttablet startup, overwriting the data dir created by mysqlctl.
Vitess relies on adding comments to DMLs, which are later parsed on the other end of replication for various post-processing work. The critical ones are:
In order to achieve this, Vitess also rewrites all your DMLs to be primary-key based. In a way, this also makes statement based replication almost as efficient as row-based replication (RBR). So, there should be no major loss of performance if you switched to SBR in Vitess.
RBR will eventually be supported by Vitess.
Vitess supports data types at the MySQL 5.5 level. The newer data types like spatial or JSON are not supported yet. Additionally, the TIMESTAMP data type should not be used in a primary key or sharding column. Otherwise, Vitess cannot predict those values correctly and this may result in data corruption.
Vitess cannot guarantee data consistency if the schema contains constructs with side effects. These are triggers, stored procedures and foreign keys. This is because the resharding workflow and update stream cannot correctly detect what has changed by looking at a statement.
This rule is not strictly enforced. You are allowed to add these things, but at your own risk. As long as you’ve ensured that a certain side-effect will not break Vitess, you can add it to the schema.
Similar guidelines should be used when deciding to bypass Vitess to send statements directly to MySQL.
Vitess also requires you to turn on STRICT_TRANS_TABLES mode. Otherwise, it cannot accurately predict what will be written to the database.
It’s safe to apply backward compatible DDLs directly to MySQL. VTTablets can be configured to periodically check the schema for changes.
There is also work in progress to actively watch the binlog for schema changes. This will likely happen around release 2.1.
MySQL autocommit needs to be turned on.
VTTablet uses connection pools to MySQL. If autocommit was turned off, MySQL will start an implicit transaction (with a point in time snapshot) for each connection and will work very hard at keeping the current view unchanged, which would be counter-productive.
We recommend to enable read-only
and skip-slave-start
at startup.
The first ensures that writes will not be accepted accidentally,
which could cause split brain or alternate futures.
The second ensures that slaves do not connect to the master before
settings like semisync are initialized by vttablet according to
Vitess-specific logic.
By default, we enable binary logging everywhere (log-bin
),
including on slaves (log-slave-updates
).
On replica type tablets, this is important to make sure they have the
necessary binlogs in case they are promoted to master.
The slave binlogs are also used to implement Vitess features like
filtered replication (during resharding) and the upcoming update stream
and online schema swap.
Many features of Vitess require a fully GTID-based MySQL replication topology, including master management, resharding, update stream, and online schema swap.
For MySQL 5.6+, that means you must use gtid_mode=ON
on all servers.
We also strongly encourage enforce_gtid_consistency
.
Similarly, for MariaDB, you should use gtid_strict_mode
to ensure that
master management operations will fail rather than risk causing data loss
if slaves diverge from the master due to external interference.
In addition to monitoring the Vitess processes, we recommend to monitor MySQL as well. Here is a list of MySQL metrics you should monitor:
Vitess servers are written in Go.
Go, being a young language, tends to add major improvements over each version. So, the latest Go version is almost always recommended. Note that the latest Go version may be higher than the minimum version we require for compiling the binaries (see "Prerequisites" section in the Getting Started guide).
You typically don’t have to set this environment variable. The default Go runtime will try to use as much CPU as necessary. However, if you want to force a Go server to not exceed a certain CPU limit, setting GOMAXPROCS to that value will work in most situations.
The default value for this variable is 100. Which means that garbage is collected every time memory doubles from the baseline (100% growth). You typically don’t have to change this value either. However, if you care about tail latency, increasing this value will help you in that area, but at the cost of increased memory usage.
Vitess servers write to log files, and they are rotated when they reach a maximum size. It’s recommended that you run at INFO level logging. The information printed in the log files come in handy for troubleshooting. You can limit the disk usage by running cron jobs that periodically purge or archive them.
Vitess uses gRPC for communication between client and Vitess, and between Vitess servers. By default, Vitess does not use SSL.
Also, even without using SSL, we allow the use of an application-provided CallerID object. It allows unsecure but easy to use authorization using Table ACLs.
See the Transport Security Model document for more information on how to setup both of these features, and what command line parameters exist.
Vttablet, vtgate, vtctld need the right command line parameters to find the Topology Server. First the topo_implementation flag needs to be set to one of zk2, etcd2, or consul. Then they're all configured as follows:
Note that the local cell for the tablet must exist and be configured properly in
the Topology Service for vttablet to start. Local cells are configured inside
the topo server, by using the vtctl AddCellInfo
command. See
the Topology Service documentation for more
information.
VTTablet has a large number of command line options. Some important ones will be covered here. In terms of provisioning these are the recommended values
vttablet supports a number of command line options and environment variables to facilitate its setup.
The VTDATAROOT environment variable specifies the toplevel directory for all
data files. If not set, it defaults to /vt
.
By default, a vttablet will use a subdirectory in VTDATAROOT named
vt_NNNNNNNNNN
where NNNNNNNNNN
is the tablet id. The tablet_dir
command-line parameter allows overriding this relative path. This is useful in
containers where the filesystem only contains one vttablet, in order to have a
fixed root directory.
When starting up and using mysqlctl
to manage MySQL, the MySQL files will be
in subdirectories of the tablet root. For instance, bin-logs
for the binary
logs, data
for the data files, and relay-logs
for the relay logs.
It is possible to host different parts of a MySQL server files on different
partitions. For instance, the data file may reside in flash, while the bin logs
and relay logs are on spindle. To achieve this, create a symlink from
$VTDATAROOT/<dir name>
to the proper location on disk. When MySQL is
configured by mysqlctl, it will realize this directory exists, and use it for the
files it would otherwise have put in the tablet directory. For instance, to host
the binlogs in /mnt/bin-logs
:
Create a symlink from $VTDATAROOT/bin-logs
to /mnt/bin-logs
.
When starting up a tablet:
/mnt/bin-logs/vt_NNNNNNNNNN
will be created.$VTDATAROOT/vt_NNNNNNNNNN/bin-logs
will be a symlink to
/mnt/bin-logs/vt_NNNNNNNNNN
VTTablet requires multiple user credentials to perform its tasks. Since it's required to run on the same machine as MySQL, it’s most beneficial to use the more efficient unix socket connections.
app credentials are for serving app queries:
dba credentials will be used for housekeeping work like loading the schema or killing runaway queries:
repl credentials are for managing replication. Since repl connections can be used across machines, you can optionally turn on encryption:
filtered credentials are for performing resharding:
VTTablet exports a wealth of real-time information about itself. This section will explain the essential ones:
This page has a variety of human-readable information about the current VTTablet. You can look at this page to get a general overview of what’s going on. It also has links to various other diagnostic URLs below.
This is the most important source of information for monitoring. There are other URLs below that can be used to further drill down.
Vitess has a structured way of exporting certain performance stats. The most common one is the Histogram structure, which is used by Queries:
"Queries": {
"Histograms": {
"PASS_SELECT": {
"1000000": 1138196,
"10000000": 1138313,
"100000000": 1138342,
"1000000000": 1138342,
"10000000000": 1138342,
"500000": 1133195,
"5000000": 1138277,
"50000000": 1138342,
"500000000": 1138342,
"5000000000": 1138342,
"Count": 1138342,
"Time":<PHONE_NUMBER>87,
"inf": 1138342
}
},
"TotalCount": 1138342,
"TotalTime":<PHONE_NUMBER>87
},
The histograms are broken out into query categories. In the above case, "PASS_SELECT" is the only category. An entry like "500000": 1133195
means that 1133195
queries took under 500000
nanoseconds to execute.
Queries.Histograms.PASS_SELECT.Count is the total count in the PASS_SELECT category.
Queries.Histograms.PASS_SELECT.Time is the total time in the PASS_SELECT category.
Queries.TotalCount is the total count across all categories.
Queries.TotalTime is the total time across all categories.
There are other Histogram variables described below, and they will always have the same structure.
Use this variable to track:
"Results": {
"0": 0,
"1": 0,
"10": 1138326,
"100": 1138326,
"1000": 1138342,
"10000": 1138342,
"5": 1138326,
"50": 1138326,
"500": 1138342,
"5000": 1138342,
"Count": 1138342,
"Total": 1140438,
"inf": 1138342
}
Results is a simple histogram with no timing info. It gives you a histogram view of the number of rows returned per query.
Mysql is a histogram variable like Queries, except that it reports MySQL execution times. The categories are "Exec" and “ExecStream”.
In the past, the exec time difference between VTTablet and MySQL used to be substantial. With the newer versions of Go, the VTTablet exec time has been predominantly been equal to the mysql exec time, conn pool wait time and consolidations waits. In other words, this variable has not shown much value recently. However, it’s good to track this variable initially, until it’s determined that there are no other factors causing a big difference between MySQL performance and VTTablet performance.
Transactions is a histogram variable that tracks transactions. The categories are "Completed" and “Aborted”.
Waits is a histogram variable that tracks various waits in the system. Right now, the only category is "Consolidations". A consolidation happens when one query waits for the results of an identical query already executing, thereby saving the database from performing duplicate work.
This variable used to report connection pool waits, but a refactor moved those variables out into the pool related vars.
"Errors": {
"Deadlock": 0,
"Fail": 1,
"NotInTx": 0,
"TxPoolFull": 0
},
Errors are reported under different categories. It’s beneficial to track each category separately as it will be more helpful for troubleshooting. Right now, there are four categories. The category list may vary as Vitess evolves.
Plotting errors/query can sometimes be useful for troubleshooting.
VTTablet also exports an InfoErrors variable that tracks inconsequential errors that don’t signify any kind of problem with the system. For example, a dup key on insert is considered normal because apps tend to use that error to instead update an existing row. So, no monitoring is needed for that variable.
"InternalErrors": {
"HungQuery": 0,
"Invalidation": 0,
"MemcacheStats": 0,
"Mismatch": 0,
"Panic": 0,
"Schema": 0,
"StrayTransactions": 0,
"Task": 0
},
An internal error is an unexpected situation in code that may possibly point to a bug. Such errors may not cause outages, but even a single error needs be escalated for root cause analysis.
"Kills": {
"Queries": 2,
"Transactions": 0
},
Kills reports the queries and transactions killed by VTTablet due to timeout. It’s a very important variable to look at during outages.
There are a few variables with the above prefix:
"TransactionPoolAvailable": 300,
"TransactionPoolCapacity": 300,
"TransactionPoolIdleTimeout":<PHONE_NUMBER>00,
"TransactionPoolMaxCap": 300,
"TransactionPoolTimeout":<PHONE_NUMBER>0,
"TransactionPoolWaitCount": 0,
"TransactionPoolWaitTime": 0,
Just like TransactionPool, there are variables for other pools:
There are other internal pools used by VTTablet that are not very consequential.
The above three variables table acl stats broken out by table, plan and user.
If the application does not make good use of bind variables, this value would reach the QueryCacheCapacity. If so, inspecting the current query cache will give you a clue about where the misuse is happening.
These variables are another multi-dimensional view of Queries. They have a lot more data than Queries because they’re broken out into tables as well as plan. This is a priceless source of information when it comes to troubleshooting. If an outage is related to rogue queries, the graphs plotted from these vars will immediately show the table on which such queries are run. After that, a quick look at the detailed query stats will most likely identify the culprit.
These variables are yet another view of Queries, but broken out by user, table and plan. If you have well-compartmentalized app users, this is another priceless way of identifying a rogue "user app" that could be misbehaving.
These variables are updated periodically from information_schema.tables. They represent statistical information as reported by MySQL about each table. They can be used for planning purposes, or to track unusual changes in table stats.
This URL prints out a simple "ok" or “not ok” string that can be used to check if the server is healthy. The health check makes sure mysqld connections work, and replication is configured (though not necessarily running) if not master.
This URL has an MRU list of consolidations. This is a way of identifying if multiple clients are spamming the same query to a server.
This URL displays the currently active query blacklist rules.
This URL prints out a simple "ok" or “not ok” string that can be used to check if the server is healthy.
Alerting is built on top of the variables you monitor. Before setting up alerts, you should get some baseline stats and variance, and then you can build meaningful alerting rules. You can use the following list as a guideline to build your own:
A typical VTGate should be provisioned as follows.
Since VTGate is stateless, you can scale it linearly by just adding more servers as needed. Beyond the recommended values, it’s better to add more VTGates than giving more resources to existing servers, as recommended in the philosophy section.
Load-balancer in front of vtgate to scale up (not covered by Vitess). Stateless, can use the health URL for health check.
single
: disallow multi-db transactions, multi
: allow multi-db transactions with best effort commit, twopc
: allow multi-db transactions with 2pc commit.This is the landing page for a VTGate, which can gives you a status on how a particular server is doing. Of particular interest there is the list of tablets this vtgate process is connected to, as this is the list of tablets that can potentially serve queries.
This is the main histogram variable to track for vtgates. It gives you a break up of all queries by command, keyspace, and type.
It shows the number of tablet connections for query/healthcheck per keyspace, shard, and tablet type.
This URL gives you all the query plans for queries going through VTGate.
This URL shows the vschema as loaded by VTGate.
For VTGate, here’s a list of possible variables to alert on:
Things that need to be configured:
We recommend to take backups regularly e.g. you should set up a cron job for it. See our recommendations at /user-guide/backup-and-restore/#backup-frequency.
You will need to run some cron jobs to archive or purge log files periodically.
Orchestrator is a tool for managing MySQL replication topologies, including automated failover. It can detect master failure and initiate a recovery in a matter of seconds.
For the most part, Vitess is agnostic to the actions of Orchestrator, which operates below Vitess at the MySQL level. That means you can pretty much set up Orchestrator in the normal way, with just a few additions as described below.
For the Kubernetes example, we provide a sample script to launch Orchestrator for you with these settings applied.
Orchestrator needs to know some things from the Vitess side, like the tablet aliases and whether semisync is enforced (with async fallback disabled). We pass this information by telling Orchestrator to execute certain queries that return local metadata from a non-replicated table, as seen in our sample orchestrator.conf.json:

There is also one thing that Vitess needs to know from Orchestrator, which is the identity of the master for each shard, if a failover occurs.
From our experience at YouTube, we believe that this signal is too critical for data integrity to rely on bottom-up detection such as asking each MySQL if it thinks it's the master. Instead, we rely on Orchestrator to be the source of truth, and expect it to send a top-down signal to Vitess.
This signal is sent by ensuring the Orchestrator server has access to
vtctlclient
, which it then uses to send an RPC to vtctld, informing
Vitess of the change in mastership via the
TabletExternallyReparented
command.
"PostMasterFailoverProcesses": [
"echo 'Recovered from {failureType} on {failureCluster}. Failed: {failedHost}:{failedPort}; Promoted: {successorHost}:{successorPort}' >> /tmp/recovery.log",
"vtctlclient -server vtctld:15999 TabletExternallyReparented {successorAlias}"
],
Normally, you need to seed Orchestrator by giving it the addresses of MySQL instances in each shard. If you have lots of shards, this could be tedious or error-prone.
Luckily, Vitess already knows everything about all the MySQL instances that comprise your cluster. So we provide a mechanism for tablets to self-register with the Orchestrator API, configured by the following vttablet parameters:
Not only does this relieve you from the initial seeding of addresses into Orchestrator, it also means new instances will be discovered immediately, and the topology will automatically repopulate even if Orchestrator's backing store is wiped out. Note that Orchestrator will forget stale instances after a configurable timeout.

Ex-CIA officer gets 19 years in China spy conspiracy
ALEXANDRIA: A former CIA case agent was sentenced to 19 years in prison Friday for an espionage conspiracy in which prosecutors say he received more than $840,000 from China to divulge the names of human sources and his knowledge of spycraft.
The sentence imposed on Jerry Chun Shing Lee, 55, was significantly longer than the 10-years sought by defense attorneys.
Lee pleaded guilty to conspiracy to commit espionage, but prosecutors and defense lawyers disagreed about whether there was proof Lee carried out any actual espionage. Lee’s lawyers disputed that their client’s conduct was anywhere near as severe as the government described.
Prosecutors say Chinese intelligence officers gave Lee more than $840,000 over a three-year period beginning in 2010, and that Lee likely gave them all the information he had from a 13-year career as a CIA case officer. They sought a prison term of more than 20 years.
Defense lawyers say the government never proved that the money came from China or that Lee ever carried out any plans to deliver government secrets.
"What the government is describing is their worst possible nightmare,” said defense lawyer Nina Ginsberg, but she argued that the government could only speculate that its nightmare scenario actually occurred.
Prosecutors acknowledged they had no direct evidence to prove what was transmitted, nor proof that the $840,000 in cash that Lee deposited into his bank account came from Chinese intelligence.
But prosecutors said Lee was never able to come up with a good explanation for where he got the cash. He ran a tobacco business in Hong Kong, but it was essentially a failure, prosecutors said.
"The only logical conclusion,” said prosecutor Neil Hammerstrom, is that that Chinese intelligence "must have been getting top-drawer, high quality (information) from this defendant.”
Prosecutor Adam Small said the government believes Lee turned over information that was found in a notebook and thumb drive that were found in his possession. That included the names of eight CIA clandestine human sources, Small said, people that Lee himself recruited and handled in his years as a CIA case agent from 1994 to 2007.
Small said the Chinese intelligence officers who met with Lee also gave him more than 20 "taskings” in which they sought details of CIA spycraft, like how they communicate with sources and maintain their cover.
"Everything he knew would have been highly valuable to the PRC,” Small said.
At Friday’s sentencing hearing, U.S. District Judge T.S. Ellis III sided largely with prosecutors. He said he agreed with the conclusion that at least some of the money Lee put into his bank must have come from China, and that he in turn must have divulged at least some classified information.
"I do think something of value changed hands. I just can’t be certain,” Ellis said. At a sentencing hearing, though, Ellis said prosecutors need not prove beyond a reasonable doubt that an act occurred for him to take it into consideration. He can consider it if prosecutors prove it to be more likely true than not.
Ginsberg said there’s no evidence that any of the sources identified in Ginsberg’s notebook were harmed or compromised in any way.
"I dare to say the government would certainly know if their agents had been exposed,” Ginsberg said.
At a press conference after the sentencing, though, U.S. Attorney for the Eastern District of Virginia G. Zachary Terwilliger disputed that assertion. He acknowledged that the U.S. might know if one of its sources suffered physical harm, but could have no idea if the Chinese used that information in a more subtle way.
"We have very talented adversaries,” he said. "It could be used in a multitude of ways.”
Terwilliger said Lee joins the "wall of infamous traitors” who have been prosecuted for spying at the Alexandria courthouse, which has jurisdiction over the CIA and large parts of the intelligence community.
In particular, Lee’s case drew comparisons to Kevin Mallory, a former CIA officer who was sentenced to 20 years in prison earlier this year for disclosing secrets to China in exchange for $25,000.
Prosecutors said the money Lee received dwarfed what Mallory got and shows that Lee’s activities were even more severe. Defense lawyers responded that nothing disclosed by Lee exceeded the "Secret” classification level, while some of what Mallory disclosed was classified as Top Secret.
Lee, for his part, apologized for his actions.
"I take full responsibility for my conduct,” said Lee, a naturalized U.S. citizen who immigrated to Hawaii from Hong Kong with his family when he was 15.

NAME
Joose.Cookbook - How to cook a Joose
DESCRIPTION
The Moose cookbook is a series of recipes showing various Joose features.
Most recipes present some code demonstrating some feature, and then explain the details of the code.
You should probably read the Joose.Manual first. The manual explains Joose concepts without being too code-heavy.
RECIPES
Basic Joose
These recipes will give you a good overview of Joose's capabilities, starting with simple attribute declaration,
and moving on to more powerful features like method modifiers, and more.
A simple Joose-based class. Demonstrates Joose attributes and subclassing.
=item L
- A simple B example
A slightly more complex Joose class. Demonstrates using a method
modifier in a subclass.
=item L - A lazy B example
Demonstrates several attribute features, including types, weak
references, predicates ("does this object have a foo?"), defaults,
laziness, and triggers.
=item L - Subtypes, and modeling a simple B class hierarchy
Introduces the creation and use of custom types, a C method,
and the use of C in a subclass.
=item L - More subtypes, coercion in a B class
More type examples, including the use of type coercions.
=item L - The augment/inner example
Demonstrates the use of C method modifiers, a way of turning
the usual method overriding style "inside-out".
=item L - Making Joose fast with immutable
Making a class immutable greatly increases the speed of accessors and
object construction.
=item L - Builder methods and lazy_build
The builder feature provides an inheritable and role-composable way to
provide a default attribute value.
=item L - Operator overloading, subtypes, and coercion
Demonstrates using operator overloading, coercion, and subtypes to
model how eye color is determined during reproduction.
=item L - Using BUILDARGS and BUILD to hook into object construction
This recipe demonstrates the use of C and C to hook
into object construction.
=item L - Extending a non-Joose base class
In this recipe, we make a Joose-based subclass of L, a
module which does not use Joose itself.
=back
=head2 Joose Roles
These recipes will show you how to use Joose roles.
=over 4
=item L - The Joose::Role example
Demonstrates roles, which are also sometimes known as traits or
mix-ins. Roles provide a method of code re-use which is orthogonal to
subclassing.
=item L - Advanced Role Composition - method exclusion and aliasing
Sometimes you just want to include part of a role in your
class. Sometimes you want the whole role but one of its methods
conflicts with one in your class. With method exclusion and aliasing,
you can work around these problems.
=item L - Applying a role to an object instance
In this recipe, we apply a role to an existing object instance.
=back
=head2 Meta Joose
These recipes show you how to write your own meta classes, which lets
you extend the object system provided by Joose.
=over 4
=item L - Welcome to the meta-world (Why Go Meta?)
If you're wondering what all this "meta" stuff is, and why you should
care about it, read this "recipe".
=item L - A meta-attribute, attributes with labels
One way to extend Joose is to provide your own attribute
metaclasses. Attribute metaclasses let you extend attribute
declarations (with C) and behavior to provide additional
attribute functionality.
=item L - Labels implemented via attribute traits
Extending Joose's attribute metaclass is a great way to add
functionality. However, attributes can only have one metaclass.
Applying roles to the attribute metaclass lets you provide
composable attribute functionality.
=item L - Adding a "table" attribute to the metaclass
If you want to store more information about your classes, you'll have
to extend C. Doing so is simple, but you'll
probably also want to provide some sugar, so see
L as well.
=item L - The "table" attribute implemented as a metaclass trait
This recipe takes the class metaclass we saw in the previous recipe
and reimplements it as a metaclass trait.
=item L - A method metaclass for marking methods public or private
This recipe shows a custom method metaclass that implements making a
method private.
=item L - Using a blessed array reference as an object instance
This recipe shows an example of how you create your own meta-instance
class. The meta-instance determines the internal structure of object
instances and provide access to attribute slots.
=item Joose::Cookbook::Meta::Recipe8 - Hooking into immutabilization (TODO)
Joose has a feature known as "immutabilization".
If you are creating your own metaclasses, you may need to hook into
the immutabilization system. This cuts across a number of spots,
including the metaclass class, meta method classes, and possibly the
meta-instance class as well.
This recipe shows you how to write extensions which immutabilize
properly.
=back
=head2 Extending Joose
These recipes cover some more ways to extend Joose, and will be useful
if you plan to write your own C module.
=over 4
=item L - Joose extension overview
There are quite a few ways to extend Joose. This recipe provides an
overview of each method, and provides recommendations for when each is
appropriate.
=item L - Providing a base object class role
Many base object class extensions can be implemented as roles. This
example shows how to provide a base object class debugging role that
is applied to any class that uses a notional C
module.
=item L - Providing an alternate base object class
You may find that you want to provide an alternate base object class
along with a meta extension, or maybe you just want to add some
functionality to all your classes without typing C over and over.
=item L - Acting like Joose.pm and providing sugar Joose-style
This recipe shows how to provide a replacement for C. You
may want to do this as part of the API for a C module,
especially if you want to default to a new metaclass class or base
object class.

Help from fairy
Hi all,
Each of us - developers - has been met it - a bug causes an issue.
When we developing an application from scratch we are in a comfortable situation,
We will be able to reproduce a bug and fix it quickly.
Also we could leaved some comments in code, notes on the computer
or our brain will make retrospection
and we know what is the business case to solve.
The situation is harder when we joined the legacy project.
If in the team is person or are people who are in it from the beginning,
they could help us understand the logic, but if they left the company
and they made technologic debt we are alone.
The only positive in that situation is when at the business side,
we will meet a person who describes to us what the application or system should do.
But when the situation is hopeless and even reverse engineering don’t give results,
we could run the fairy app which gives us example causes ; - )
Currently, it is available in 2 (two) versions:
- Bash
- C
I successively adding new ones - please be patient,
Also, I inviting you to contribute to this repository.
It is everything that I have for today.
Everyone is a blacksmith of own fate.
Mateusz.


public class JMemoryPool
extends java.lang.Object
The pool works by allocating a memory blocks which are given out to any JMemory class that requests a chunk. That memory is given out, out of the pool, until the block is completely exhausted, then a new block is allocated and continues to give out the memory. The memory blocks are released and deallocated when the last JMemory block that receive any of the memory is garbage collected. When that happens the original memory block is deallocated with a native C free() call. The user does not have to do anything special, the memory management is done completely behind the scene, very efficiently and automatically using java's garbage collection mechanism.

Several application programming interfaces (APIs) are only accessible with an API Key. API Keys are granted to specific applications.
There are two types of API keys: Production Keys and Developer Keys. Production Keys are to be used by applications running in a production environment and Developer Keys are to be used for non-production purposes, including application development. It can take up to a week to process a Production Key request and receive the key, whereas a Developer Key can often be processed and received in a few minutes.

, this method returns the value of the current
symbol in the stream (which is the next symbol to be consumed). When
i==-1
, this method returns the value of the previously read
symbol in the stream. It is not valid to call this method with
i==0
, but the specific behavior is unspecified because this
method is frequently called from performance-critical code.
This method is guaranteed to succeed if any of the following are true:
i>0
i==-1
and index()
returns a value greater
than the value of index()
after the stream was constructed
and LA(1)
was called in that order. Specifying the current

relative to the index after the stream was created
allows for filtering implementations that do not return every symbol
from the underlying source. Specifying the call to LA(1)
allows for lazily initialized streams.LA(i)
refers to a symbol consumed within a marked region
that has not yet been released.If i
represents a position at or beyond the end of the stream,
this method returns EOF

operations will be
valid over a "marked range" extending from the index where mark()
was called to the current index()
. This allows the use of
streaming input sources by specifying the minimum buffering requirements
to support arbitrary lookahead during prediction.
The returned mark is an opaque handle (type int
) which is passed
to release()
when the guarantees provided by the marked
range are no longer necessary. When calls to
mark()
/release()
are nested, the marks must be released
in reverse order of which they were obtained. Since marked regions are
used during performance-critical sections of prediction, the specific
behavior of invalid usage is unspecified (i.e. a mark is not released, or
a mark is released twice, or marks are not released in reverse order from
which they were created).
The behavior of this method is unspecified if no call to an
initializing method
has occurred after this stream was
constructed.
This method does not change the current position in the input stream.
The following example shows the use of mark()
,
release(mark)
, index()
, and
seek(index)
as part of an operation to safely work within a
marked region, then restore the stream position to its original value and
release the mark.
IntStream stream = ...; int index = -1; int mark = stream.mark(); try { index = stream.index(); // perform work here... } finally { if (index != -1) { stream.seek(index); } stream.release(mark); }

General Electric grabs finance chief from shipping group Maersk
COPENHAGEN (Reuters) - A.P. Moller-Maersk’s (MAERSKb.CO) finance chief Carolina Dybeck Happe will leave the shipping group to take up a similar position at General Electric (GE.N) early next year, the companies said on Monday.
She will replace Jamie S. Miller at General Electric, the U.S. company said in a statement.
Dybeck Happe, who joined Maersk in January this year, is the second senior executive in two weeks to announce her departure from Maersk.
The company’s chief operating officer Morten Toft left to take up the role of CEO of rival MSC’s cargo business.

Dynamic Landing Page is re-usable in all kinds of ways. There are two pieces of the interface that can be modified by the end-user. The modified values are stored into local cache.
I'd like to thanks Pexels.com for supplying the nice images for this project.

You have seen how to create a Paginator object, how to render the items on the current page, and how to render a navigation element to browse through your pages. In this section you will see how Paginator fits in with the rest of your MVC application.
In the following examples we will ignore the best practice implementation of using a Service Layer to keep the example simple and easier to understand. Once you get familiar with using Service Layers, it should be easy to see how Paginator can fit in with the best practice approach.
Lets start with the controller. The sample application is simple, and we’ll just put everything in the IndexController and the IndexAction. Again, this is for demonstration purposes only. A real application should not use controllers in this manner.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | class IndexController extends Zend\Controller\Action
{
public function indexAction()
{
// Setup pagination control view script. See the pagination control tutorial page
// for more information about this view script.
Zend\View\Helper\PaginationControl::setDefaultViewPartial('controls.phtml');
// Fetch an already instantiated database connection from the registry
$db = Zend\Registry\Registry::get('db');
// Create a select object which fetches blog posts, sorted descending by date of creation
$select = $db->select()->from('posts')->order('date_created DESC');
// Create a Paginator for the blog posts query
$paginator = Zend\Paginator\Paginator::factory($select);
// Read the current page number from the request. Default to 1 if no explicit page number is provided.
$paginator->setCurrentPageNumber($this->_getParam('page', 1));
// Assign the Paginator object to the view
$this->view->paginator = $paginator;
}
}
|
The following view script is the index.phtml view script for the IndexController’s indexAction. The view script can be kept simple. We’re assuming the use of the default ScrollingStyle.
1 2 3 4 5 6 7 8 9 |

<?php
// Render each the title of each post for the current page in a list-item
foreach ($this->paginator as $item) {
echo '
' . $item["title"] . '
';
}
?>

<?php echo $this->paginator; ?>
|
Now navigate to your project’s index and see Paginator in action. What we have discussed in this tutorial is just the tip of the iceberg. The reference manual and API documentation can tell you more about what you can do with Zend_Paginator.
