The parser stage consists of two parts:
The parser defined in gram.y and scan.l is built using the Unix tools bison and flex.
The transformation process does modifications and augmentations to the data structures returned by the parser.
The parser has to check the query string (which arrives as plain ASCII text) for valid syntax. If the syntax is correct a parse tree is built up and handed back; otherwise an error is returned. The parser and lexer are implemented using the well-known Unix tools bison and flex.
The lexer is defined in the file scan.l and is responsible for recognizing identifiers, the SQL key words etc. For every key word or identifier that is found, a token is generated and handed to the parser.
The parser is defined in the file gram.y and consists of a set of grammar rules and actions that are executed whenever a rule is fired. The code of the actions (which is actually C code) is used to build up the parse tree.
The file scan.l is transformed to the C source file scan.c using the program flex and gram.y is transformed to gram.c using bison. After these transformations have taken place a normal C compiler can be used to create the parser. Never make any changes to the generated C files as they will be overwritten the next time flex or bison is called.
Note: The mentioned transformations and compilations are normally done automatically using the makefiles shipped with the PostgreSQL source distribution.
A detailed description of bison or the grammar rules given in gram.y would be beyond the scope of this paper. There are many books and documents dealing with flex and bison. You should be familiar with bison before you start to study the grammar given in gram.y otherwise you won't understand what happens there.
The parser stage creates a parse tree using only fixed rules about the syntactic structure of SQL. It does not make any lookups in the system catalogs, so there is no possibility to understand the detailed semantics of the requested operations. After the parser completes, the transformation process takes the tree handed back by the parser as input and does the semantic interpretation needed to understand which tables, functions, and operators are referenced by the query. The data structure that is built to represent this information is called the query tree.
The reason for separating raw parsing from semantic analysis is that system catalog lookups can only be done within a transaction, and we do not wish to start a transaction immediately upon receiving a query string. The raw parsing stage is sufficient to identify the transaction control commands (BEGIN, ROLLBACK, etc), and these can then be correctly executed without any further analysis. Once we know that we are dealing with an actual query (such as SELECT or UPDATE), it is okay to start a transaction if we're not already in one. Only then can the transformation process be invoked.
The query tree created by the transformation process is structurally similar to the raw parse tree in most places, but it has many differences in detail. For example, a FuncCall node in the parse tree represents something that looks syntactically like a function call. This might be transformed to either a FuncExpr or Aggref node depending on whether the referenced name turns out to be an ordinary function or an aggregate function. Also, information about the actual data types of columns and expression results is added to the query tree.

Summer-in-lab in Oxford
For the past two month, I had the great pleasure of doing experiments with Philipp Kukura’s group at the department of Chemistry in Oxford. This was an opportunity created by the superb hospitality of Philipp and his group members, and me not taking enough vacation days for the previous two years. Spending most of my time in the lab and getting my hands busy with some of the most sensitive optical microscopes in the world was a remarkable experience. I am no stranger to sensitive microscopes, but the iSCAMS technology, with its unique combination of sensitivity and ease of operation, is a real breakthrough. Each week I saw some visiting researchers coming with their samples in ice-boxes and at the end of the day leaving with a smile on their face because of the incredible measurements they could take in a single day. …

Four undergraduate projects start today
Four new projects related to various aspects of electrokinetic tracking will start today. Lorenzo Peres is going to make a microfluidic channel with embedded electrodes. This channel hopefully allows him to measure surface charge of the channel as function of flow. Peter Speets will also use a similar channel to study growth and shrinkage of protein aggregates using nanoparticle tracking and resonant light scattering. Milo Colaris will use an acoustic levitator to measure the viscosity of a floating droplet of a suspension as it dries. The method he develps will be later applied to very small droplets trapped with an optical tweezers. …

U-Talent project with a DIY-microscope
Last September, 4 students from the U-Talent program performed their final project in our group. They used a DIY-microscope, previously developed in the bachelor project of Kevin Namink, to measure the Brownian motion of nanoparticles. Their goal was to measure the viscosity of the liquid by determination of the Diffusion constant. De Odysee van een deeltje in een suspensie was presented with remarkable confidence by Lucas Abbenhuis, Evert Sarolea, Samuel Klumpers, and Jip Ridderbos during the final thesis-symposium in an almost full classroom. Here is a shot from the back of the room. …

Migrating to GitHub pages
After several years of happily administring my personal pages with the mediawiki software on my old website and less happily paying the ever-increasing hosting fees, I thought of migrating to the github pages.

SCOTTISH SUN SAYS
Jeremy Corbyn’s plans for £11bn raid on North Sea oil sector could not be more idiotic
by The Scottish SunLABOUR were in turmoil in Scotland before today’s manifesto launch.
If anything, they’re now in even deeper trouble. Jeremy Corbyn’s manifesto rabbit, it turned out, was an £11billion raid on the North Sea oil sector.
The timing of this insane, short-sighted cash grab could not be more idiotic.
The struggling industry is still on its knees following the slump that started in 2014 and ravaged jobs and the north-east economy in the years that followed.
More than 100,000 livelihoods were lost then, at a conservative estimate.
And now the sector is just about picking itself back up, in part thanks to tax cuts and investment from the UK and Scottish Governments to encourage innovation and exploration.
Getting firms to invest — and not simply cut their losses and flee — has been hard enough in recent years.
This windfall tax will only make things worse.
And it risks the recovery that’s needed to put firms in a financially sound place, necessary for the decades of decommissioning that will follow the industry’s inevitable decline.
As Aberdeen University’s Professor Alex Kemp points out, the policy is also based on a mistaken belief that firms should have been taxed harder historically in line with countries like Norway.
This is comparing apples and pears, with taxes lower in the UK basin because the oil has been, generally, more expensive to extract in our waters than in Scandinavia.
It’s this kind of schoolboy error — or fundamental misunderstanding of reality — that has become a hallmark of Corbynomics.
Just like his pledges to boost public spending, while splurging billions on misguided nationalisations.
It doesn’t add up.
But you have to wonder if Mr Corbyn knows this — and simply wants to virtue signal and pursue his wrecking-ball ideology.
Because there appears to be a warping of reality with Labour.
Take their pledge for free school dinners in Scotland. It may sound nice, but education is devolved.
People have enough trouble understanding the complex political landscape without red herrings like this.
It’s no wonder polls show no sign of budging in Mr Corbyn’s favour.
He’s detached from reality.
And this manifesto isn’t going to change his woes.
Rogue Royals
EVEN at 93 the Queen has acted decisively.
But Andrew is not the only Prince doing her damage.
She is right to warn Harry and Meghan too.
She should demand they keep out of politics, cease the “woke” lectures and needy self-pity — and buckle down to some Royal duties.
Or they can sling their hook too.

HOA to crack down on homeowners who aren’t landscaping backyards
by Barbara Holland RJRealEstate.VegasQ: Our homeowners association rules state that owners must landscape their backyard within six months. We have residents who have been here as long as 13 years and have never touched their backyard.
The builder/declarant never enforced most of our covenants, conditions and restrictions. Now that we have a homeowner board, I was wondering what can be done to enforce the landscaping of the backyards. We can’t “trespass” onto people’s property to take a picture. Since pictures are now required, how do we go about sending them a picture of their violation? You can look down the side yards and assume, seeing nothing but rocks and dirt, that the rest of the backyard is the same. Please tell us what we can do to enforce this violation.
A: One recommendation is for your board to have the management company send a letter to those homeowners stating the requirement from the CC&Rs.
In that letter, management can request a copy of their architectural approval letter and/or taking a photograph of their backyard. Homeowners would have “x” amount of days to comply. In addition, management can review the homeowner records to see which homes have backyard landscaping. It is a process, but it can be done.
Q: Can we approve the budget with an amount for landscaping, based on our current vendor, and then get quotes to bid it out?
Can the president only decide if renters can come to a meeting? Someone she knows came to our meeting (first time that this has ever happened), and she said he can stay but can’t participate in conversation. Yet he voiced a concern about the upstairs neighbor. Our property manager agreed to this.
Once again, thank you for your expertise on HOA. Do you teach any classes for HOA board members?
A: If you think that you will be changing your landscape company, then it would be more prudent to estimate the new landscape expenses and use that number for your 2020 budget and not the current expense.
The decision to allow renters to attend a board meeting should be made by the board of directors. If you do allow renters, then a policy should be made by the board as to allowing the renters to speak during the homeowner forum.

23yo Injects Petroleum Jelly to Look Like Popeye, Muscles Are Now Rotting & He Could Die
by Sheralyn TanTap to listen to this article instead: 🔊 Listen to Post
A 23-year-old bodybuilder who wanted to be like Popeye the Sailor Man had to undergo surgery to remove his arm implants because he could die if he didn’t do so.
Kirill Tereshin from Russia, who had injected about three litres of petroleum jelly into each arm to bulk up his biceps and triceps, was told that he would need to undergo double amputation if he didn’t get rid of his disastrous implants that had caused his muscles to rot.
According to The Sun, he had injected the petroleum jelly so thoroughly that it spread in the muscle and killed it. He even started having high fever, strong pain and weakness as a result.
During the surgery, the surgeon had to remove lumps of jelly and pounds of flesh from Kirill’s 24-inch arms. In the process, he managed to remove a massive lump of scar tissue and fragments of muscles that weighed three pounds!
“Kirill injected about three litres into each arm. It saturated the muscle tissues, blocked blood flow,” the doctor said.
“As a result the tissue dies and gets replaced with a scar which is as tough as a tree, you can even knock on it and hear the usual sound.”
After his initial surgery, Tereshin will have to undergo at least three more and hopefully retain arm movement after, but his fake muscles will be gone.
“Petroleum jelly saturates the muscles, under skin tissues and the skin itself,” the surgeon said.
“All that has to be removed, but we need to keep the vein, nerves and other functions of the limb.”
The surgeon then said that Kirill was “lucky” that the damage had remained only in his limbs and not spread to the rest of his body.

The apples are allowed to stew at the bottom of the baking dish while the cake mixture cooks on top. The name is a reference to Eve and the Tree of Knowledge of Good and Evil.
The earliest known version, in Mary Eaton's 'The Cook and Housekeeper's Dictionary' of 1823, predates baking powder and therefore uses a breadcrumb-and-egg sponge.
Mother Eves pudding from 1860 contained apples, but with suet and was boiled.
"Take of sliced apple, well washed currants, grated bread, and finely shred suet, each twelve ounces, mix them in a bowl, with half the rind of a lemon, minced, and moisten with four well-beaten eggs. Boil in a buttered mould, and serve with a sweet sauce, as follows:- Sweeten a quarter of a pint of melted butter, add nutmeg, a large glassful of sherry, and part of the juice of a lemon.

I learned about Joseph Conrad’s “Preface” to the Nigger of the Narcissus thanks to a passage mentioned in this conversation between Ian McEwan and Steven Pinker. I went on to read it, and found it utterly enlightening. Here’s the opening first paragraph, that I wish I could read every morning.
The Preface can be read here.

pitch_salary['salary'].hist(figsize=(5,5))
plt.xlabel('Salary')
plt.ylabel('Count')
<matplotlib.text.Text at 0x9afd0f0>
Most players have the salary less than 10,0000 dollars.I will make four levels of the salary range and use a pie chart to see the percentage of each level.
salary_min = pitch_salary['salary'].min()
salary_max = pitch_salary['salary'].max()
salary_group = np.arange(salary_min,salary_max+1,(salary_max-salary_min)/4)
def t(x):
for tag in salary_group:
if x<tag:
return str(tag/100000)
m = pitch_salary['salary'].copy()
m['salary'] = pitch_salary['salary'].apply(t)
b=m.groupby('salary')
b.count()
b.count().plot.pie(autopct='%.1f',figsize=(8,8))
# plt.xlabel('Salary')
plt.xlabel('uint:10,000 dollars')
plt.title('Salary Distribution')
<matplotlib.text.Text at 0xa554978>
conclusion
The figure above shows that most players(nearly 90%) have the salary below 0.82 million dolloars.Less than 10% of the players has more than 1 million dollars.Define the players who has more than 1 million dollars salary as well-paid players.
Double Variable Analysis:
What’s the relationship betweent the factor and salary?
I choose the BFP,GIDP,HR to analysis.Take a look of these factors’s distribution.
pitch_salary[['BFP','GIDP','HR','salary']].hist(figsize=(10,5,))
array([[<matplotlib.axes._subplots.AxesSubplot object at 0x0000000003BF3898>,
<matplotlib.axes._subplots.AxesSubplot object at 0x000000000E8EA908>],
[<matplotlib.axes._subplots.AxesSubplot object at 0x000000000A9FCEB8>,
<matplotlib.axes._subplots.AxesSubplot object at 0x000000000DCF25C0>]], dtype=object)
HR,GIDP,salary have the same distribution.But the BFP’s distribution seems different.There is a fall around 100 and a bounce around 700.
Is there any linear relationship between these factors and salary?
I will check the scatter plot and calculate the $R^2$ to evaluation the linear relationship.
from sklearn.metrics import r2_score
from scipy import stats
# this function caculate the r^2 and make the scatter plot
def R_2(item):
slope, intercept, r_value, p_value, std_err = stats.linregress(pitch_salary[item],pitch_salary['salary'])
pitch_salary.plot.scatter(x = item,y = 'salary',s=50,figsize=(6,6))
plt.title(item+'-Salary Scatter')
return r_value**2
R_2('HR')
0.088281672003010361
R_2('GIDP')
0.066004780276815292
R_2('BFP')
0.097620388739633468
conlusion
As all the R^2 are smaller than 0.1,there is no strong linear relationship between those factor and salary.But maybe there is other nolinear relationship.
What’s the difference betweent the well-paid players and others?
We think well-paid players will have the better perfomance than others.Is it true?
well_paid_boundry = 8200000
well_paid_pitcher = pitch_salary[pitch_salary['salary']>well_paid_boundry]
other_pitcher = pitch_salary[pitch_salary['salary']<=well_paid_boundry]
# used for plot density map
def density_map(item):
well_paid_pitcher[item].plot(kind = 'density',title = item+'-'+'density map')
other_pitcher[item].plot(kind = 'density')
return
density_map('HR')
density_map('BFP')
density_map('GIDP')
The red lines represent the well-paid players,the blue lines represent the others.We can find that well-paid have much higher score than the others.
Hypothesis testing
Null Hypothesis:well-paid players have the same BFP as other players.
Alternative Hypothesis: well-paid players have more BFP than other players.
Use $\mu_0$ as the mean of well-paid players,$\mu_1$ as the mean of other players.
$\alpha=0.01$
$H_0:{\mu_0=\mu_1}$
$H_\alpha:{\mu_0>\mu_1}$
$t_{critical} = 2.6$
We need to caculate the SS to get the t_stastic.
def t_test(x1,x2):
avg1 = x1.mean()
avg2 = x2.mean()
n1 = x1.count()
n2 = x2.count()
df1 = n1 - 1
df2 = n2 - 1
SS1 = ((x1 - avg1)*(x1-avg1)).sum()
SS2 = ((x2 - avg2)*(x2-avg2)).sum()
S_p2 = (SS1+SS2)/(df1+df2)
S_xy = np.sqrt(S_p2/n1+S_p2/n2)
t = (avg1-avg2)/S_xy
return t
t_test(well_paid_pitcher['BFP'],other_pitcher['BFP'])
16.340974029004389
$t_{statistic} = 16.34$
conclusion
We reject the null hypothesis and retain the alternative hypothesis.Players with well-paid have more BFP than the other players.
Use the same method we can get the similar conclusion in GIDP and HR.It’s can be convinced that well-paid players also have a higher factor such as BFP,HR and GIDP.
Summary
At first,I drop many NaN values to make anlysist easier.But it also bring some problem.It makes the sample smaller.As there is no other information why those values are lost,the analysist may go wrong.


Module 4 Labeling Values in our Dataset
Although it is customary to use Stata’s Data Editor for defining and applying labels, the Variable manager can be a rather useful option for this task. In this module, we will explore how to label values of data set variables, and we will use the Variable manager to accomplish this. By the end of this module, students should:
- become familiar with basic requirements and or procedures of labeling values of some variables in a data set
- be able to use Stata’s Variable manager feature to label variable values in a data set
The Variable manager feature can be brought up by clicking the spreadsheet icon on Stata’s toolbar, as shown below:
We will open the Variables Manager and define a value label for one of the variables in our data set, study_level (which describes respondents level of study, i.e either graduate, undergraduate or diploma). In this activity, we will use the Variables Manager to define the value labels. Let’s start.
In the Variable Properties pane, click on the Manage… button next to the Value label field (see figure 1.8).
This will open a new dialog box called Manage value labels (again see figure 1.9 below)
Because we have no value labels yet, nothing is listed. Click on Create label, and the Create label dialog box opens as shown in figure 2.0.
For Label name, type Study. Bear in mind that this is not the name of the variable but a sort of sobriquet for the set of labels we will use for the variable. For Value, type 1; press on Tab button to go to Label (you can also click inside the Label box if you don’t want to use Tab, and start typing) and type graduate; and then click Add. Next type 2 under Value; press the Tab button to go to Label and type undergraduate and then click Add. Again, type 3 under value then Tab to Label for the final time and type diploma then click Add. See figure 2.1 for a screen shot of the results:
Figure 2.1 shows the Create Labels dialog box after performing the activities above. Since we have no more values, click on OK to close the Create label dialog box. Doing this adds the label study to the Manage value labels dialog box. Now click on the Close button of the Manage value labels dialog box to return to the Variables Manager. In the Variable Properties pane, we can click on the drop-down menu for Value label and select our label of study. Then click on Apply. You will notice that the value label for study_level is now study in the list of variables on the left.
Now using what we have learned so far, let us define more value labels for our data set:
- click on the Manage… button next to Value label,
- then click on Create label, which opens the Create label dialog box.
- Let us make a label sobriquet of Views that we will apply to tuition_hike. This new label is intended to describe respondents’ views of the new tuition hike introduced by the Newfoundland government.
- For Value, type 1;
- tab to Label and type Very Unfair;
- then click on Add.
- Repeat this step to add the following values and labels for the views value label:
| values | Labels |
|---|---|
| 2 | Fair |
| 3 | I’m not sure |
| 4 | Unfair |
| 5 | Very Unfair |
Let us repeat these steps, starting by clicking on Create Label, and create value labels named status (fee_status), sex (gender), impacts (effects), and funding (fee_type) with the following values and labels:
| Label name | Value | Label |
|---|---|---|
| sex | 1 | Male |
| 2 | Female | |
| 3 | Other | |
| 4 | Prefer not to say | |
| status | 1 | canadian/permanent resident |
| 2 | international student | |
| impacts | 1 | Very affected |
| 2 | Affected | |
| 3 | Not sure | |
| 4 | Slightly affected | |
| 5 | Not affected at all | |
| funding | 1 | Self-funded |
| 2 | Scholarship | |
| 3 | Prefer not to say |
- Once we finish creating the last value label, we then click on Close in the Manage value labels dialog box. This takes us back to the Variables Manager.
- Here we can click on any variable - for example, gender, then click on the drop-down menu next to Value label and select one of the sobriquets we just created, in this case, sex. Clicking on Apply will assign this set of value labels to the gender variable. We can repeat this for fee_status by selecting status from the drop-down menu. Similarly, we can select impacts for effects, study for study_level, views for tution_hike and finally, funding for fee_type.
Finally, let us add a note to our dataset. To do this,
- bring up the Variable manager if it is not already the active window,
- and right-click on any of the variables, for example, id.
- A drop-down menu appears with several useful options including Manage notes for dataset… Click on this option, and we see a dialog box open with an option to add notes.
- Click on Add and then type These data were collected for my term project for POSC 3010 in March of 2015.
- Next, click on Submit and then Close to close the dialog box.
Dataset notes can be very useful for keeping track of general changes in the dataset. To see how the notes look in the data set, type this command into your Stata Command window: describe. Next, type notes. The output can be seen below:
Going through a series of dialog boxes can be confusing. Remember however, that if you face any difficulty completing any of these tasks, I am always available to help, both in person and via email (syo837@mun.ca.)

Strengths My trust in the process. I believe that everything comes in due time if you trust in the process that has been laid out. My confidence to understand myself in knowing what works best for me to retain information in the best way. Limitations My lack of confidence in my sense of patience and competitive nature. Controlling my emotions in a productive way will be key.
I believe that most positive things in life deserve 100% attention when the time is set aside. This is what will be required for this course. 100% attention during the designated timeframe of each day.
Two methods. Step one; to access online resources. The act of searching is all valuable with a reasonable amount of time. Step two; to consult the team or facilitator directly about the matter.

This is a prototype for showcasing a Surge Pricing business model. The thing about Yelp that kind of defied my logic was about how Yelp made money of the people who give its ratings till it struck home that they didn't. The money came in from the side of the business. On further research I found this to be the greatest criticism of yelp, that it didn't monetize the consumers. I had this in mind and remembered once when I was trying hard to get a reservation for a date, and I was willing to shell out extra that the idea struck me. Why not have an uber like surge pricing model for restaurants and other limited capacity areas such as golf courses and movie theaters, if there is demand then people would pay, it is simple market economics
An additional motivation behind this idea was a friend of mine, who insisted on visiting all the hot new restaurants in town. He wanted to visit all the happening places and to check-in there. For him it would be great to be able to filter restaurants based on how many people go there, the more exclusive the better.
I therefore created this prototype as a means to bring together these two needs. To allow people a way to bid higher to a place they wish to go and for the restaurant or organization to spread out their customers.
The maxim that my mentor often repeated was that "No Idea survives first contact with customers" so to confirm if I had a business model worth pursuing I went out and interviewed people, I called on 3 restaurants, a golf course and 2 Laser Tag arenas. I also spoke to a professor of mine who played golf and a few students.
I learnt from restaurants that their biggest problem with reservations is no shows. in fact the restaurants flat out refused to consider charging customers for reservations, mainly because the customers would just take their business elsewhere. They expressed frustration over the fact that the customers could give them a bad rating but they still had to put up with them even if they don't show up and cost them on their margins
I however had a more positive response from the golf course and laser tag arenas. they said that it would make sense to collect a higher reservation fee. They were confident that they wouldn't lose their clientele because there aren't many alternatives. but they said they would need to check when would be the best time to implement a surge pricing model. The Professor and students also mirrored this opinion, they said they might pay for the golf course or laser tag locations but they definitely wouldn't pay for a restaurant


To begin, select a type of tableau for your output, using the radio buttons. Selecting a radio button will change the type used in subsequent runs of the algorithm.
The page can be used in two ways. First, you can have the page generate a random signed permutation. To do that, enter the size of the desired permutation in the first textbox. Then click the Run button directly to the right. The Run button will display a randomly-generated signed permutation and the output of the Robinson-Schensted algorithm when applied to that permutation. The defects of that tableau pair, the places where the tableaux are not special, are marked with colored squares. After that, the page displays the tableaux made special.
Instead, you can enter a permutation in the second textbox. To do that, list the (positive and negative) numbers of the signed permutation, separated by spaces. Then, use the Run button to the right of that box, as above.
Pressing Enter while in one of these two textboxes will click the Run button to the right. Pressing a button a second time, or a different button, will clear the previous result as it gives you a new result, as will pressing Enter while in a textbox.
This page first displays the Domino Robinson-Schensted algorithm. The Domino Robinson-Schensted algorithm is a relatively straightforward generalization of the Robinson-Schensted algorithm to the hyperoctrahedral group, that is, the group of signed permutations. The input to the Domino Robinson-Schensted algorithm is a "signed permutation", for example, 2 -5 3 6 -4 1. That is, the numbers 1 through n are permuted, and, in addition, each number has a sign (or orientation) associated with it. The output of the Domino Robinson-Schensted algorithm is a pair of domino tableaux with the same shape. That is, instead of a tableau being made of squares, it is made of 2 x 1 shapes (dominos), which can be horizontal or vertical in the tableau. However, unlike the dominos in a game, each domino has only one number in it.
As in the original Robinson-Schensted algorithm, the left tableau is the insertion, or bumping, tableau. The right tableau is the recording tableau. In this algorithm, insertion is either as a horizontal domino in the first row, if the number in the signed permutation is positive, or as a vertical domino in the first column, if the number in the signed permutation is positive. Bumping is also more complicated. A horizontal domino which is bumped entirely moves to the next row below. A vertical domino which is bumped entirely moves to the next column to the right. A domino which is bumped in one square rotates down and to the right on its unbumped square.
After a domino is added to the insertion tableau by this procedure, the resulting change to the shape of the insertion tableau is two squares, adjacent either horizontally or vertically. A domino is then added to the recording tableau to record this change.
You can see an animation of the bumping procedure here: Domino Robinson-Schensted Algorithm Animated.
Domino tableaux are used to answer questions about simple Lie groups of type B, C, or D. To use a domino tableau for a question about a Lie group of a specific type, you need to place the tableau on the grid associated to that type. The grid is the underlying array of 2 x 2 boxes on which the domino tableau is placed. A C type tableau is placed on the grid with its top left square in the top left square of the grid. A D type tableau is placed on the grid with its top left square in the top right square of the grid. A B type tableau is placed on the grid with its top left square in the bottom right square of the grid. In addition, a B type tableau, which is associated with the group SO(2n + 1, ℂ), has a single square with a 0 in it in its top left corner.
Domino tableaux are used to classify Kazhdan-Lusztig cells in the Weyl groups of type Bn, Cn, and Dn. (Or, equivalently, they are used to classify primitive ideals in the enveloping algrbra of the complexified Lie algebra with that Weyl group.) The Domino Robinson-Schensted algorithm starts that process. However, left (or right) cells are classified by tableau with special shape with respect to their grid. To get from the output of the Robinson-Schensted algorithm to the corresponding tableau with special shape, we need to move a tableau through all its open unboxed cycles.
A tableau is special with respect to its grid if every 2 x 2 square of the grid is either filled, half-fulll, or empty (where squares above or to the left of the tableau are considered as filled.) If a 2 x 2 grid square has only one of its four squares filled, that square (called a filled corner) is marked in green. If a 2 x 2 grid square has three of its four squares filled, the empty square (called an empty hole) is marked in purple.
This page first displays the result of applying the Domino Robinson-Schensted algorithm to a signed permutation. If the original tableaux are not special, the defects are marked. Filled corners are marked with green squares. Empty holes are marked with purple squares. After that, the page displays the result of moving the tableaux through their open unboxed cycles. The change in shape is that the squares marked green are no longer in the shape of the tableaux, whereas those marked purple now are.
You can see the process of making a tableau special by moving through its open unboxed cycles on this page: Animate Cycles Special. You can see the process of making a tableau pair special by moving through its open unboxed extended cycles on this page: Animate Extended Cycles Special.

public String readSystemResource(URL url); public String readSystemResource(File file); public String readSystemResource(String path); public InputStream getInputStream(String path); public FileInputStream getFileInputStream(String path); public FileInputStream getFileInputStream(File file); public FileOutputStream getFileOutputStream(File file);One of the tricky cases is for URLS. Because a URL can point to the local file system RAMADDA needs to check that it is not a "file:" URL. It does this with the following code:
... if (path.toLowerCase().trim().startsWith("file:")) { f = new File(path.substring("file:".length())); checkFile(f); return; }This also includes when RAMADDA reads a URL. The exploit to watch for with respect to URL reading is a URL that is a file URL, e.g.: file:/etc/passwrd
The exception to the above is in a few places where the database access is done by a admin user.
The access control mechanism around the data model (i.e., the entries) also makes use of this facility in that for a particular api access there can be a specification of the access rights to the entry (e.g., view, edit, delete, new, etc). Furthermore, when creating the internal Entry data structures RAMADDA checks if the user requesting the entry has view permissons.


Christmas comes early for two Waterford punters who won over €5.3m in Lotto prizes
"This win is a complete game-changer for us. We are renting a house at the moment so the dream of buying a house was always a difficult one for us"
by Ian ManganChristmas came early for two separate Waterford punters who walked away with over €5.3 million in Lotto and scratch card prizes.
The National Lottery confirmed that the lucky ticket holder who won the whopping €5,260,021 Lotto jackpot on Wednesday, October 23, has now collected their prize.
Their staggering win comes just as the festive season approaches and is sure to take the sting out of this year’s Christmas shopping.
The winning ticket was sold at the SuperValu store at the Kilbarry shopping centre in Waterford City and was the 8th Lotto jackpot of 2019 with over €50 million paid out in jackpot prizes alone this year.
And the Deise good luck didn’t stop there, as another Waterford winner scooped up a tasty win on a scratch card.
Thomas Coughlan from Waterford City got an early Christmas bonus after he won one of the €100,000 top prizes on a Christmas Countdown scratch card.
Lotto bosses confirmed that there is still one top prize remaining on the €10 Christmas scratch card.
Coughlan said he was ‘dumbstruck’ by his massive win which he says is a ‘game-changer’ for him and his fiancée Meghan Simpson and their four-year old son.
The young family have said they plan to spend their winnings on a new home and a wedding in the next 12 months.
He said, “Quite simply, this win is a complete game-changer for us. We are renting a house at the moment so the dream of buying a house was always a difficult one for us.
“Trying to save while renting isn’t ideal but with this win, we are that much closer to getting our forever home.
"And more importantly – we had to sacrifice getting married over buying a house so in the next year, we will have a new home and we will be married, we’re just absolutely thrilled.”
Coughlan, who works as an architect in Waterford City, bought the winning scratch card on his way home from work last Friday at O’Hare’s supermarket on the Dunmore Road.
He added, “It’s something we always do every single Friday – we treat ourselves to a scratch card to celebrate the start to the weekend.

“After we scratched off the €100,000 symbols, we were just dumbstruck and we sat there staring at each other, absolutely certain that we had made a mistake.
"We jumped back into the car and went back to the shop and they told us that we had a winning ticket.
“It was just an unbelievable weekend celebrating with family and friends who are absolutely thrilled for us.”


I originally wrote this post for an open source project I worked on called TF2 Stadium. The post was originally available at http://blog.tf2stadium.com. I am re posting it now since the blog has been shut down. It is mostly semi technical information that was released as teaser/promotional content in the early stages of development. TF2Stadium is a Team Fortress 2 lobby website where competitive players are matched with other players for practice matches.
Original post date: 03 SEP 2015
Hello, and welcome to the first actual entry of the TF2Stadium developer blog. In this entry, we will summarize some of the technology that our site uses, as well as some of our design goals.
The programming of TF2Stadium–as well as most other sites–is split into two major groups: “frontend” and “backend”.
The Frontend
Frontend is everything from the way the page looks to the experience of using the site. The frontend is made up of HTML, CSS, and Javascript, which together form the page that a user sees.
TF2Stadium is a Single Page Application, which means the entire site and most of its assets are loaded during the initial load of the page. After that, navigation does not require page loads, which in turn make the site much more responsive. This isn’t free of downsides however, such as a longer initial loading time and the necessity of using Javascript.
We are using AngularJS as a web framework. Web frameworks are used to remove or lessen the need for small and repetitive operations when writing code. It is a Javascript framework developed in-house by Google to produce dynamic web applications. Using AngularJS will result in cleaner and easier to maintain code. This is so we can focus on programming what we want our site to be without needing to create a coding structure first. AngularJS gives us that engine we can write on top of.
We decided before development began to follow the principles set out by Material Design. In short, Material Design is a “Visual Language” which takes advantage of a bold and clean feel, while not sacrificing usability. The Material design spec was also developed by Google and can be seen in a lot of their products. The Angular-Material library allows our developers to create Material interfaces using the aforementioned AngularJS.
For styling, we use an extension called “Sass” for CSS3 (also known as SCSS). Sass is the clear choice for the project due to its relatively simple nature, and its superb maintainability. It also removes the need to repeat CSS statements throughout the stylesheets, which eliminates needless code.
The backend of TF2Stadium refers to everything that goes on server-side. The backend is written in the Go Programming Language. Go is developed and maintained by Google and the open source community. Recently it has seen increased adoption in the cloud with companies like Facebook, Dropbox, and Google using it in a variety of in-house projects. Go implements powerful facilities and an extensive standard library which provides a wide range of functionality.
For anyone interested, our Go stack uses:
- Gorilla Web Toolkit - URL routing and session cookies
- ORM interface to PostgreSQL - database related operations
- go-socket.io - communication with the frontend
- SimpleJSON - Go library to interact with arbitrary JSON
- op-logging - logging framework
- james4k’s rcon Go library - sending and receiving messages over the RCON protocol
- testify - testing suite (including assertions) for unit tests
Our interactions with TF2 are managed by two programs written by our backend team: Pauling and Helen. Helen is responsible for maintaining the database and keeping track of active lobbies and stats. It is also responsible for communicating with the frontend. Pauling handles everything related to the game servers. It connects to the game servers via RCON, then exposes an API to Helen. The API is then used to allow Helen to make Pauling send RCON commands for configuring servers, verifying connections to check if the server is still up, and executing a league config and whitelist for each server. It also listens to the server logs and notifies Helen about events like the match ending, and players connecting and disconnecting from the server.
We have also written two Go libraries: PlayerStatsScraper and TF2RconWrapper. Pauling uses TF2RconWrapper, a library written by one of our team members which wraps around james4k’s rcon for TF2-specific operations and commands. Player stats (hours played, name, and country) are retrieved using PlayerStatsScraper.
The Link
Both parts communicate with each other through a protocol called WebSocket. This allows for a two-way conversation between the Frontend and the Backend, meaning both of them can send requests to each other which are rapidly processed without the need of a refresh in the page.
For example, Helen can tell the Frontend that a new lobby was created only once, and the latter doesn’t have to periodically ask “which lobbies are open”. It just has to react to the messages it has received. Likewise, the Frontend can notify Helen who will send a message to every user online saying “There’s a new message. Here it is.”
