RestartManager
(dump_time=1080.0, dump_step=None, dumper=None)¶ Bases:
object
A restart manager which does two things: it decides when restart files were created (when doDump returns true) and manages directories for restart files. The method getNewDumper creates a new directory and returns its name.
This restart manager will decide to dump restart files every dump_step calls of doDump or if more than dump_time since the last dump has elapsed. The restart manager controls two directories for dumping restart data, namely for the current and previous dump. This way the previous dump can be used for restart in the case the current dump failed.
Variables: -
__init__
(dump_time=1080.0, dump_step=None, dumper=None)¶ Initializes the RestartManager.
Parameters: - dump_time – defines the minimum time interval in SEC between two
dumps. If
None
, time is not used as criterion. - dump_step – defines the number of calls of doDump between two
dump events. If
None
, the call counter is not used as criterion. - dumper – defines the directory for dumping restart files. Additionally, the directories dumper+”_bkp” and dumper+”_bkp2” are used. If the directory does not exist it is created. If dumper is not present a unique directory within the current working directory is used.
- dump_time – defines the minimum time interval in SEC between two
dumps. If

There was a king who had a daughter who never could be induced to laugh; she was always sad. So the king proclaimed that she should be given to any one who could cause her to laugh. There was also a shepherd who had a son named George.
He said: “Daddy! I, too, will go to see whether I can make her laugh. I want nothing from you but the goat.”
His father said, “Well, go.”
The goat was of such a nature that, when her master wished, she detained everybody, and that person was obliged to stay by her.
So he took the goat and went, and met a man who had a foot on his shoulder. George said: “Why have you a foot on your shoulder?”
He replied: “If I take it off, I leap a hundred miles.”
“Whither are you going?”
“I am going in search of service, to see if any one will take me.”
“Well, come with us.”
They went on, and again met a man who had a bandage on his eyes. “Why have you a bandage on your eyes?”
He answered, “If I remove the bandage, I see a hundred miles.”
“Whither are you going?”
“I am going in search of service, if you will take me.”
“Yes, I’ll take you. Come also with me.”
They went on a bit farther, and met another fellow, who had a bottle under his arm, and, instead of a stopper, held his thumb in it.  If you like, take me also into your service; it may be to your advantage and ours too.”
George replied: “Well, come, too!”
Afterward they came to the town where the king lived, and bought a silken riband for the goat. They came to an inn, and orders had already been given there beforehand, that when such people came, they were to give them what they liked to eat and drink—the king would pay for all. So they tied the goat with that very riband and placed it in the innkeeper’s room to be taken care of, and he put it in the side room where his daughters slept. The innkeeper had three maiden daughters, who were not yet asleep.
So Manka said: “Oh! If I, too, could have such a riband! I will go and unfasten it from that goat.”
The second, Dodla, said: “Don’t; he’ll find it out in the morning.”
But she went notwithstanding. And when Manka did not return for a long time, the third, Kate, said: “Go, fetch her.”
So Dodla went, and gave Manka a pat on the back. “Come, leave it alone!”
And now she, too, was unable to withdraw herself from her. So Kate said: “Come, don’t unfasten it!”
Kate went and gave Dodla a pat on the petticoat; and now she, too, couldn’t get away, but was obliged to stay by her.
In the morning George made haste and went for the goat, and led the whole set away—Kate Dodla, and Manka. The innkeeper was still asleep.
They went through the village, and the judge looked out of a window and said, “Fie, Kate! What’s this? What’s this?”
He went and took her by the hand, wishing to pull her away, but remained also by her. After this, a cowherd drove some cows through a narrow street, and the bull came rushing round; he stuck fast, and George led him, too, in the procession.
Thus they afterward came in front of the castle, and the servants came out-of-doors; and when they saw such things they went and told the king. “Oh, sire, we have such a spectacle here; we have already had all manner of masquerades, but this has never been here yet.”
So they immediately led the king’s daughter to the square in front of the castle, and she looked and laughed till the castle shook.
Now they asked him what sort of person he was. He said that he was a shepherd’s son, and was named George. They said that it could not be done; for he was of mean lineage, and they could not give him the damsel; but he must accomplish something more for them.
He said, “What?”
They replied that there was a spring yonder, a hundred miles off; if he brought a goblet of water from it in a minute, then he should obtain the damsel.
So George said to the man who had the foot on his shoulder: “You said that if you took the foot down, you could jump a hundred miles.”
He replied: “I’ll easily do that.”
He took the foot down, jumped, and was there. But after this there was only a very little time to spare, and by then he ought to have been back. So George said to the other: “You said that if you removed the bandage from your eyes, you could see a hundred miles. Peep and see what is going on.”
“Ah, sir! Goodness gracious! He’s fallen asleep!”
“That will be a bad job,” said George; “the time will be up. You, third man, you said if you pulled your thumb out, you could squirt a hundred miles; be quick and squirt thither, that he may get up.
He then gave a jump, and was there exactly in time.
After this they said that he must perform one task more; that yonder, in a rock, was a wild beast, a unicorn, of such a nature that he destroyed a great many of their people; if he cleared him out of the world he should obtain the damsel. So he took his people and went into the forest. They came to a firwood. There were three wild beasts, and three lairs had been formed by wallowing as they lay. Two did nothing: but the third destroyed the people. So they took some stones and some pine-cones in their pockets, and climbed up into a tree; and when the beasts lay down, they dropped a stone down upon that one which was the unicorn.
He said to the next: “Be quiet; don’t butt me.”
It said: “I’m not doing anything to you.”
Again they let a stone fall from above upon the unicorn. “Be quiet! You’ve already done it to me twice.”
“Indeed, I’m doing nothing to you.” So they attacked each other and fought together. The unicorn wanted to pierce the second beast through; but it jumped out of the way, and he rushed so violently after it, that he struck his horn into a tree, and couldn’t pull it out quickly. So they sprang speedily down from the fir, and the other two beasts ran away and escaped, but they cut off the head of the third, the unicorn, took it up, and carried it to the castle.
Now those in the castle saw that George had again accomplished that task. “What, prithee, shall we do? Perhaps we must after all give him the damsel!”
“No, sire,” said one of the attendants, “that cannot be; he is too lowborn to obtain a king’s daughter! On the contrary, we must clear him out of the world.”
So the king ordered them to note his words, what he should say. There was a hired female servant there, and she said to him: “George, it will be evil for you to-day; they’re going to clear you out of the world.”
He answered: “Oh, I’m not afraid. When I was only just twelve years old, I killed twelve of them at one blow!”
But this was the fact: when his mother was baking a flat-cake, a dozen flies settled upon her, and he killed them all at a single blow.
When they heard this, they said: “Nothing else will do but we must shoot him.”
So they drew up the soldiers, and said they would hold a review in his honour, for they would celebrate the wedding in the square before the castle. Then they conducted him thither, and the soldiers were already going to let fly at him.
But George said to the man who held his thumb in the bottle in the place of a stopper: “You said, if you pulled your thumb out, you could besprinkle everything. Pull it out—quick!”
“Oh, sir, I’ll easily perform that.”
So he pulled out his thumb and gave them all such a sprinkling that they were all blind, and not one could see.
So, when they perceived that nothing else was to be done, they told him to go, for they would give him the damsel. Then they gave him a handsome royal robe, and the wedding took place. I, too, was at the wedding; they had music there, sang, ate, and drank; there was meat, there were cheesecakes, and baskets full of everything, and buckets full of strong waters. To-day I went, yesterday I came; I found an egg among the tree-stumps; I knocked it against somebody’s head, and gave him a bald place, and he’s got it still.


SINFO is a college student and non-profitable organization responsible for the planning of one of the biggest Tech events in Portugal. It’s an annual conference that takes place at the Alameda Campus of Técnico Lisboa, in the capital city of Portugal, Lisbon. We had a record breaking attendance of participants last year, achievement we hope to repeat next year, from February 18th to 22nd 2019.
At SINFO, our mission is to give students and general attendants the opportunity to interact and get closer to influential and thriving people in the fields of Information Technology and Computer Science. We also bring tech companies of major relevance to our attendants so they can communicate with those companies’ employees, share experiences and maybe find a future position. We try to make it happen every day with dedication, by continuously improving the quality of our event, not only by bringing new speakers for every edition but also innovativing companies and startups that share our love for technology.
We live in an increasingly technological world in constant and swirling motion, where Computer Science and IT play fundamental roles. For the last 25 editions SINFO has been the bridge between that world and the student community. Every single one of them sums up several months of dedication and hard work laid out by its members, who are driven by the rewarding smiles of SINFO’s participants and the desire to surpass themselves every year. We like to think we’ve managed to do both hitherto. Our goal is to inspire and be inspired.
We are mainly focused on bringing the ultimate technological experience to the student community. Nonetheless, everyone fascinated by IT or seeking a new career opportunity is welcome to join us.

Taxi Driver Chad'z rating: ***1/2 (out of 4 = very good) 1976, R, 114 minutes [1 hour, 54 minutes] [drama] starring: Robert De Niro (Travis Bickle), Cybill Shepherd (Betsy), Jodie Foster (Iris), Harvey Keitel (Matthew), written by Paul Schrader, produced by Michael and Julia Phillips, directed by Martin Scorsese.
What's great about the movies is they allow us to get to know anonymous strangers. Usually the characters we meet are likable and relatable, but "Taxi Driver" tries to rob us of the innocence we're used to with a character study of a person everyone's encountered but never given a second thought to.
New York City has been and always will be associated with crime, pollution, ghettos, and the "scum" that comes with them. Everyone thinks the streets could and should be cleaned up, but most realize there's nothing that can really be done about it and don't let it get to them. Travis Bickle (De Niro) wishes he could feel that way, he's a Vietnam veteran who drives a taxi throughout city and can't help noticing the Hellish nature of the city and the society it breeds. Bickle himself seems to be forming his own reality as we constantly hear his narration of his obsession and hatred for the city and his own life.
It's easy to sympathize with Bickle as Scorsese paints a bleak, Gothic-like portrait of the city by emphasizing the heat and humidity of the summer as there always seems to be steam or mist rising from the sewers and the streets. Most of the action takes place at night where only the neon signs from cheap diners and adult movie theaters provide light. Bickle's passengers tend to be the "spooks" people avoid such as drunks, prostitutes, two-bit criminals, and "normal" people who relieve their neurosis in the privacy and anonymity of the cab (including one funny, yet disturbing scene with a cameo by Scorsese).
The entire film seems to be a long letter to society, written by Bickle, attempting to justify his mental deterioration. The first half shows his struggle to cope and be a normal person. He charms a political organizer named Betsy (Shepherd) into going out with him (why she ever liked him is beyond me). But he blows it and when she refuses to see him again he blames her and thinks she's the same as all the other scum, just better dressed.
As the film progresses Bickle slips deeper and deeper into his own world. He buys several guns illegally and it seems as if he will become a vigilante, but besides stopping a robbery, this doesn't happen. He also finds himself bumping into a young teenage prostitute named Iris (Foster) whom he wants to "save" from her pimp Matthew (Keitel).
Little happens in terms of plot, and although there are a few good scenes of Bickle's attempt to make a difference with Iris, he becomes entirely too twisted to relate to because there isn't enough (if any) back-story present. I'm sure the fact he's a veteran has something to do with it, but why not have flashbacks to something traumatic in his life? As good a job as Scorsese does in depicting the nihilism Bickle is obsessed with, he doesn't give enough specific examples. The ending is too surreal for its own good, but I guess it follows the film's logical conclusion.
Although "Taxi Driver" works as a good narrative and establishment of mood, there's still a lot more that could have been done. De Niro's performance is excellent especially considering how pathetic his character is and how exhausting it must be to carry the film virtually solo. Still, the elements that make it up are well assembled and entertaining, but most of all original.

‘Battle with Israel “not over” despite ceasefire’: Hamas Chief
Gaza: Ismail Haniyeh, the Hamas chief, said that the battle with Israel is “not over” although the new wave of violence in the Gaza Strip is over. Haniyeh made the remarks on Sunday after he gave his condolences to the Abu Malhous family which lost eight of its members in the last round of violence between Israel and the Palestinian Islamic Jihad, Xinhua news agency reported. “Our victory in the previous round is not counted by the number of the fired rockets, nor by the losses sustained, but by the fact that resistance has completely paralyzed the entity (Israel) during the escalation,” he told reporters.

Burgers
A hamburger (or burger for short) is a food, typically considered a sandwich, consisting of one or more cooked patties—usually ground meat, typically beef—placed inside a sliced bread roll or bun. The patty may be pan fried, grilled, smoked or flame broiled. Hamburgers are often served with cheese, lettuce, tomato, onion, pickles, bacon, or chilis; condiments such as ketchup, mustard, mayonnaise, relish, or a "special sauce", often a variation of Thousand Island dressing; and are frequently placed on sesame seed buns. A hamburger topped with cheese is called a cheeseburger.[1] The term burger can also be applied to the meat patty on its own, especially in the United Kingdom, where the term patty is rarely used, or the term can even refer simply to ground beef. Since the term hamburger usually implies beef, for clarity burger may be prefixed with the type of meat or meat substitute used, as in beef burger, turkey burger, bison burger, portobello burger, or veggie burger. Hamburgers are typically sold at fast-food restaurants, diners, and specialty and high-end restaurants. There are many international and regional variations of hamburgers.

09. Practice Block Data
Let's do some Coding Practice
In the previous concept, you explored the Bitcoin block data with the block explorer. Now, it is time to practice Promises with Node.js and explore the block data in your own terminal.
Steps to follow
Step 1 Explore libraries to explore the block data in Javascript Step 2 Discuss how can we solve the problem Step 3 Walk you through the boilerplate code Step 4 Review some tips
Each step you’ll take to complete this exercise is called out in the comments throughout the code. You can find more details and guidance about each of these steps in the text provided below the code.
Let’s get started!
Step1. Explore libraries to explore the block data in Javascript
There are a few libraries you can use to explore the block data in Bitcoin. For this exercise, we are going to use the library provided by BlockExplorer blockexplorer.js.
This library allows to do some important operations through the network like:
blockexplorer.block(hash)
- Get block info by hashblockexplorer.rawBlock(hash)
- Get raw block info by hashblockexplorer.blockIndex(height)
- Get block hash by height
Take a look at the API description in the Node module so that you know how to use all those functions.
Step 2. Discuss how can we solve the problem
The task in this workspace is simple to accomplish: we need to implement the function getBlock(index)
.
This function allows us to show the block data from a network request in the console. To implement it, follow the following steps:
- Use the
be.blockIndex(index)
to get the hash. This is necessary because we don't have the block hashes. - Use the
be.block(hash)
to request the entire block data. - Use
console.log(block)
to show the data in the console.
All the methods in the blockexplorer.js return Promises. Remember that this concept is necessary in modern applications because it allows you to execute your code asynchronously. If you need a refresher on Promises, check out this Udacity free course on Promises.
Step 3. Walk you through the boilerplate code
In all Node.js applications, if you need to use a Third Party Library (a module that was developed by someone else), you'll need to install the module:
npm i blockexplorer --save
.
The first part of the code template you have:
const be = require('blockexplorer');
This allows you to use the blockexplorer module in your application.
Then, you have the following function:
function getBlock(index) {
//Add your code here
// Start by requesting the hash
// Then request the block and use console.log
}
The last part of the code is the following function:
(function theLoop (i) {
setTimeout(function () {
getBlock(i);
i++;
if (i < 3) theLoop(i);
}, 3600);
})(0);
This function allows you to create a loop that executes each step every 3.6s. Inside the loop, we are going to call the getBlock
function.
Because of the loop function, we are going to see 3 different blocks of data in the console.
Step 4. Review these tips.
- Remember all the blockexplorer.js functions return a Promise.
- Check the results that you get from all the methods. For example, when you use
blockIndex(index)
function, the result is:{blockHash:ah93jioj9ij3dj93d9j39ij9}
. That means it is returning an object. You will need to parse the result in order to use the hash in the next function:let hashAux = JSON.parse(hash).blockHash;
. - Don't worry about the following warning:
node:323) Warning: a promise was created in a handler at /home/workspace/Project/app.js:12:12 but was not returned from it, see http://goo.gl/rRqMUw
at new Promise (/home/workspace/Project/node_modules/bluebird/js/release/promise.js:79:10)
This is something related to the Workspace tool and is not related to the code. If you try the exercise in your own environment, you won't get this warning.
To run the application:
- Open the terminal.
- Move to the project folder
cd Project
. - Write in the console
node app.js
.

RTS Prototype: Part 2
Introduction
In this document we're going to expand on what we did in Part 1 by adding new unit types, redesigning the interface, implementing a resource management system,
and generally extending the functionality to more closely match features found in a basic real-time strategy game.
This builds directly on work done in RTS Prototype: Part 1, so if you have not completed it you had better get your rear back over there
and finish that before proceeding.
The sound files that accompany this tutorial are here (RTS2_sounds.zip). All button and interface image files are inline with the text below.
New Unit Type Setup
The first thing we're going to do is create datablocks for our new unit types. This will make it easier for us to get started with most of the other things we're going to be
building since everything else ultimately deals with making or controlling them.
Under game/art/datablocks, create a new folder called ai and copy game/art/datablocks/aiPlayer.cs into the new folder. Rename
game/art/datablocks/ai/aiPlayer.cs to game/art/datablocks/ai/infantry.cs. Next, modify the datablock in the new file so that the new datablock is named InfantryUnit.
datablock PlayerData(InfantryUnit : DefaultPlayerData)
{
shootingDelay = 2000;
mainWeapon = Lurker;
};
Do this for the GrenadierUnit, EngineerUnit, and MedicUnit datablocks as well.
Now, in game/art/datablocks/aiPlayer.cs add code to load the new unit datablocks:
...
// load our new AI datablocks:
exec("./ai/infantry.cs");
exec("./ai/engineer.cs");
exec("./ai/grenadier.cs");
exec("./ai/medic.cs");
//-----------------------------------------------------------------------------
// Demo Pathed AIPlayer.
//-----------------------------------------------------------------------------
...
Now we have enough of a stub in for our unit types to proceed with building the UI and unit build request systems.
UI Restructure
The current UI works for basic demonstration purposes, but we'll need to add quite a bit to it before it really becomes a useful RTS interface. While we are going to add to it, we are not going to go all out and make a complete interface to rival commercial titles. Our purpose here is still to illustrate how the underlying systems can be built and we need a certain minimum set of interface elements to do that.
Create New UI Art Items
First, we're going to need some artwork. I totally cheated and used T3D's "Empty Room" mission to get a profile screenshot of our stock Soldier armed with both the Lurker rifle and the Ryder pistol, then converted this to a silouette to use for my button images. I then took the weapon UI art from the games/art/gui folder to use for additional elements. Finally, I used PaintShop Pro 5 and Paint.NET to hammer out my buttons.
Torque 3D uses "nine-slice" images for many of its interface objects. A "nine-slice" image refers to an image that is "sliced" into nine pieces (tic-tac-toe fashion) by a specific color (usually a "pure" primary color like 255,0,0 which rarely shows up in actual images) that the engine loads up as separate image elements internally. The GuiBitmapButtonCtrl does this but uses 36 "slices" arranged vertically in groups of nine. Each slice group contains the image slices for one of its button states (normal, hover/highlight, depressed, and disabled). These are my button images:
| Infantry | Engineer | Grenadier | Medic | Barracks 1 | Barracks 2 |
|
|
|
|
|
|
The button states are (from top down) Normal, Depressed, Hover, and Disabled. You can download them for use by right-clicking each image and selecting "save image as..." from the context menu.
We'll also add some images for other UI elements. Panel and image border nine-slice images, and various sized resource symbol images:
| Panel | Border | Resource 1 | Resource 2 | Resource 3 |
|
|
|
|
|
With our assets ready, we just need to add some control profiles and we can start working on the interface layout. In art/gui/customProfiles.cs add the following profile definitions:
singleton GuiControlProfile ("ControlPanelBorderProfile")
{
bitmap = "art/gui/panelBorderArray";
hasBitmapArray = true;
opaque = "0";
};
if( !isObject( GuiEngineerButtonProfile ) )
new GuiControlProfile( GuiEngineerButtonProfile )
{
opaque = true;
border = true;
fontColor = "50 50 50";
fontColorHL = "0 0 0";
fontColorNA = "200 200 200";
fixedExtent = false;
justify = "center";
canKeyFocus = false;
bitmap = "./EngineerBtn.png";
hasBitmapArray = true;
category = "Core";
};
if( !isObject( GuiGrenadierButtonProfile ) )
new GuiControlProfile( GuiGrenadierButtonProfile )
{
opaque = true;
border = true;
fontColor = "50 50 50";
fontColorHL = "0 0 0";
fontColorNA = "200 200 200";
fixedExtent = false;
justify = "center";
canKeyFocus = false;
bitmap = "./GrenadierBtn.png";
hasBitmapArray = true;
category = "Core";
};
if( !isObject( GuiInfantryButtonProfile ) )
new GuiControlProfile( GuiInfantryButtonProfile )
{
opaque = true;
border = true;
fontColor = "50 50 50";
fontColorHL = "0 0 0";
fontColorNA = "200 200 200";
fixedExtent = false;
justify = "center";
canKeyFocus = false;
bitmap = "./InfantryBtn.png";
hasBitmapArray = true;
category = "Core";
};
if( !isObject( GuiMedicButtonProfile ) )
new GuiControlProfile( GuiMedicButtonProfile )
{
opaque = true;
border = true;
fontColor = "50 50 50";
fontColorHL = "0 0 0";
fontColorNA = "200 200 200";
fixedExtent = false;
justify = "center";
canKeyFocus = false;
bitmap = "./MedicBtn.png";
hasBitmapArray = true;
category = "Core";
};
if( !isObject( GuiBarracksTeam01ButtonProfile ) )
new GuiControlProfile( GuiBarracksTeam01ButtonProfile )
{
opaque = true;
border = true;
fontColor = "50 50 50";
fontColorHL = "0 0 0";
fontColorNA = "200 200 200";
fixedExtent = false;
justify = "center";
canKeyFocus = false;
bitmap = "./Barracks01Btn.png";
hasBitmapArray = true;
category = "Core";
};
if( !isObject( GuiBarracksTeam02ButtonProfile ) )
new GuiControlProfile( GuiBarracksTeam02ButtonProfile )
{
opaque = true;
border = true;
fontColor = "50 50 50";
fontColorHL = "0 0 0";
fontColorNA = "200 200 200";
fixedExtent = false;
justify = "center";
canKeyFocus = false;
bitmap = "./Barracks02Btn.png";
hasBitmapArray = true;
category = "Core";
};
At this point we should be ready to start on revamping PlayGui.
Create RTS Interface
Open the GUI Editor and load up PlayGui:
With the modifications we made in Part 1, the PlayGui should be the base PlayGui GameTSCtrl control which should contain the centerPrintDlg, the bottomPrintDlg, the LagIcon, and GuiShapeNameHud controls, along with their child controls where appropriate. If any other controls are present in PlayGui they should be removed.
Once we have a "clean" PlayGui, we'll add a GuiBitmapBorderCtrl from the Images section of the Library:
Rename the new control RTSControlPanel and configure the controls with the following settings:
| Parameter | Value |
| position | 0 616 |
| extent | 1024 152 |
| horizSizing | center |
| vertSizing | top |
| profile | ControlPanelBorderProfile |
| isContainer | checked |
Here's a screenshot of my settings in the GUI Editor:
Point one is the position and extent, point two is the sizing method, point three is the profile, and point four is the container attribute. We will be placing other controls inside of this one and those controls will depend on this parent control for their layout, so this last is set to true.
Now to construct the rest of the build panel setup. Note the hierarchy as you proceed: Keeping each type of element in its own frame will allow you to easily rearrange elements later if you need to.
| Control Panel Background | Resource Display Frame |
| |
| Resource Icon | Resource Display Text |
| |
| Barracks Frame | Barracks Construction Button |
| |
| Unit Construction Frame | Infantry Button |
| |
| Grenadier Button | Medic Button |
| |
| Engineer Button | Infantry Text |
| |
| Grenadier Text | Medic Text |
| |
| Engineer Text |
|
Once all of these controls have been correctly created and nested you should have a control panel that looks something like this:
Implement Interface Button Callbacks In PlayGui
Implementing the button callbacks in PlayGui should be pretty straightforward. We've already got some cruft left from Part 1, so just fix and add to match the following:
// This function is the callback that handles our new button. When you click it
// the button tells the PlayGui that we're now in building placement mode.
function btnBarracks::onClick(%this)
{
PlayGui.placingBuilding = true;
PlayGui.buildingClass = "barracks";
if ($PlacementDecal $= "")
{
// create placement decal and keep it in position with the current mouse location.
}
}
function btnEngineer::onClick(%this)
{
commandToServer('requestEngineer');
}
function btnInfantry::onClick(%this)
{
commandToServer('requestInfantry');
}
function btnGrenadier::onClick(%this)
{
commandToServer('requestGrenadier');
}
function btnMedic::onClick(%this)
{
commandToServer('requestMedic');
}
Note that the InfantryBld button is now the btnBarracks button, so adjust that accordingly and add the other button callback handlers.
Create The Base Resource System
Now that we have buttons to request buildlings and units we're going to need a resource system and a way to manage our buildings and unit requests. I decided to keep it simple, so we'll use a single resource: Money. Our money will automatically replenish itself over time and we'll be able to pick up bonus money for achieving specific battlefield objectives.
First, let's create the ResourceManager. This script object is actually not as complex as it sounds - it just tracks object costs and updates client resource displays to reflect each client's current resource level. We'll throw some unit and building costs in here as stand-ins for now, but this will be an important place to come back to when it's time to start balancing the game.
In scripts/server create a new script named resourceManager.cs and add the following code to it, then save it.
$StartingResources = 150000;
$ResourceReplenish = 10;
$ResourceCap = 500000;
if (!isObject(ResourceManager))
new ScriptObject(ResourceManager);
function ResourceManager::initialize(%this)
{
%this.itemCosts[0] = "barracks,100000";
%this.itemCosts[1] = "Infantry,1000";
%this.itemCosts[2] = "Engineer,2000";
%this.itemCosts[3] = "Grenadier,2500";
%this.itemCosts[4] = "Medic,4000";
%this.schedule(1000, "update");
}
function ResourceManager::update(%this)
{
%count = ClientGroup.getCount();
for(%i = 0; %i < %count; %i++)
{
%client = ClientGroup.getObject(%i);
if(%client.costList $= "")
{
%client.costList = %this.getItemCosts();
commandToClient(%client, 'setItemCosts', %client.team, %client.costList);
}
if(%client.resourceBank $= "")
%client.resourceBank = $StartingResources;
%client.resourceBank += $ResourceReplenish;
if(%client.resourceBank > $ResourceCap)
%client.resourceBank = $ResourceCap;
commandToClient(%client, 'updateResourceDisplay', %client.resourceBank, "");
}
%this.schedule(1000, "update");
}
function ResourceManager::getCost(%this, %itemType)
{
%i = 0;
%entry = %this.itemCosts[%i];
%type = getField(%entry, 0);
%cost = getField(%entry, 1);
while (%entry !$= "" && %type !$= %itemType)
{
%entry = strreplace(%entry, ",", "\t");
%type = getField(%entry, 0);
%cost = getField(%entry, 1);
%entry = %this.itemCosts[%i++];
}
return %cost;
}
function ResourceManager::getItemCosts(%this)
{
%list = "";
%i = 0;
%entry = %this.itemCosts[%i];
while (%entry !$= "")
{
if(%list $= "")
%list = %entry;
else
%list = %list SPC %entry;
%entry = %this.itemCosts[%i++];
}
return %list;
}
First, we create some global script variables so that everyone knows what our starting amount is, how fast our money replenishes, and what our money cap amount is.
We follow that by creating the script object itself. In the initialize() method we set our item costs in an array and start our scheduled system update method on a one second schedule.
In the update() menthod we walk our clients and send them the item cost list if they don't already have it, update the client's current resource bank appropriately, then send the updated bank amount to be displayed. Finally, we reschedule our upated on our one second tick time.
The getCost() method is used by the server commands that create requested buildings or units from client requests. We'll see more of this later.
Finally, the getItemCosts() method is used internally to format our cost list to our clients in update() in a tagged string format.
In order to use this we'll need to load it, so open scripts/server/scriptExec.cs and add this line:
// Load our gametypes
exec("./gameCore.cs"); // This is the 'core' of the gametype functionality.
// --- Add this line between loading gameCore.cs and gameDM.cs
exec("./resourceManager.cs");
// --- done add.
exec("./gameDM.cs"); // Overrides GameCore with DeathMatch functionality.
We'll also want a way to manage building requests. At the moment this just handles barracks buildings, but the BldEventListener::requestBuilding() method is where we would add other types of buildings later. For now, in scripts/server create buildingManager.cs and put the following code in it:
function initializeBldEventManager()
{
if (!isObject(BldEventManager))
{
$BldEventManager = new EventManager(BldEventManager)
{
queue = "BldEventQue";
};
// Module related signals
BldEventManager.registerEvent("_RequestBuilding");
}
if (!isObject(BldListener))
{
$BldListener = new ScriptMsgListener(BldListener)
{
class = "BldEventListener";
};
// Module related subscriptions
BldEventManager.subscribe(BldListener, "_RequestBuilding", "requestBuilding");
}
}
// Cleanup the event manager
function destroyBldEventManager()
{
if (isObject(BldEventManager) && isObject(BldListener))
{
// Remove all the subscriptions
BldEventManager.remove(BldListener, "_RequestBuilding");
// Delete the actual objects
BldEventManager.delete();
BldListener.delete();
// Clear the global variables, just in case
$BldEventManager = "";
$BldListener = "";
}
}
function BldEventListener::requestBuilding(%this, %messageData)
{
//%pos, %shape, %class, %team
%pos = getField(%messageData, 0);
%class = getField(%messageData, 1);
%team = getField(%messageData, 2);
switch$(%class)
{
case "barracks":
%shape = "art/shapes/station/station0"<EMAIL_ADDRESS>}
%count = ClientGroup.getCount();
%client = "";
%found = false;
for(%i = 0; %i < %count; %i++)
{
%client = ClientGroup.getObject(%i);
if(%client.team == %team)
{
%found = true;
break;
}
}
if(!%found)
return;
if(%client.resourceBank < ResourceManager.getCost(%class))
{
bottomPrint(%client, "You don't have enough resources to build this.", 5, "You don't have enough resources to build this.");
return;
}
// spawn a new object at the intersection point
%obj = new TSStatic()
{
position = %pos;
shapeName = %shape;
class = %class;
collisionType = "Visible Mesh";
scale = "0.5 0.5 0.5";
};
%navMesh = 0;
%count = MissionGroup.getCount();
for(%i = 0; %i < %count; %i++)
{
%missionObj = MissionGroup.getObject(%i);
if(%missionObj.getClassName() $= "NavMesh")
{
%navMesh = %missionObj;
break;
}
}
if (%navMesh > 0)
NavMeshUpdateOne(%navMesh, %obj);
// Add the new object to the MissionCleanup group
MissionCleanup.add(%obj);
// Set up a spawn point for new troops to arrive at.
%teamSpawnGroup = "Team" @ %team @ "SpawnGroup";
if (!isObject(%teamSpawnGroup))
{
new SimGroup(%teamSpawnGroup)
{
canSave = "1";
canSaveDynamicFields = "1";
enabled = "1";
};
MissionGroup.add(%teamSpawnGroup);
}
%spawnName = "team" @ %team @ "Spawn" @ %obj.getId();
%point = new SpawnSphere(%spawnName)
{
radius = "1";
dataBlock = "SpawnSphereMarker";
spawnClass = $Game::DefaultPlayerClass;
spawnDatablock = $Game::DefaultPlayerDataBlock;
};
%point.position = VectorAdd(%obj.getPosition(), "0 5 2");
%teamSpawnGroup.add(%point);
MissionCleanup.add(%point);
%client.resourceBank -= ResourceManager.getCost(%class);
commandToClient(%client, 'updateResourceDisplay', %client.resourceBank, %class);
}
If you're watching closely you'll notice that the BldEventListener::requestBuilding() method strongly remsembles what is currently in the scripts/server/commands.cs createBuilding() function - that's because we're moving it from there to here so it's handled by the building management system instead, and that function will request buildings from the building manager.
We'll need to load this too, so open scripts/server/scriptExec.cs again and add this line after the last one:
// Load our gametypes
exec("./gameCore.cs"); // This is the 'core' of the gametype functionality.
exec("./resourceManager.cs");
// --- Add this line between loading resourceManager.cs and gameDM.cs
exec("./buildingManager.cs");
// --- done add.
exec("./gameDM.cs"); // Overrides GameCore with DeathMatch functionality.
Now that everything is loaded we will open scripts/server/gameDM.cs and in DeathMatchGame::startGame() we'll initialize our new objects:
function DeathMatchGame::startGame(%game)
{
//echo (%game @"\c4 -> "@ %game.class @" -> DeathMatchGame::startGame");
parent::startGame(%game);
// initialize our building request and resource systems
initializeBldEventManager();
ResourceManager.initialize();
}
While we're here, let's modify DeathMatchGame::endGame() as well:
function DeathMatchGame::endGame(%game)
{
//echo (%game @"\c4 -> "@ %game.class @" -> DeathMatchGame::endGame");
// clean up our building manager before exiting the mission
destroyBldEventManager();
parent::endGame(%game);
}
Since we've moved the heavy lifting to the building manager we can go back to scripts/server/commands.cs and simplify createBuilding() like this:
function createBuilding(%client, %pos, %start, %ray, %class)
{
// find end of search vector
%ray = VectorScale(%ray, 2000);
%end = VectorAdd(%start, %ray);
// set up to look for the terrain
%searchMasks = $TypeMasks::TerrainObjectType;
// search!
%scanTarg = ContainerRayCast( %start, %end, %searchMasks );
// If the terrain object was found in the scan
if( %scanTarg )
{
// get the world position of the click
%pos = getWords(%scanTarg, 1, 3);
// Note: getWord(%scanTarg, 0) will get the SimObject id of the object
// that the button click intersected with. This is useful if you don't
// want to place buildings on certain other objects. For instance, you
// could include TSStatic objects in your search masks and check to see
// what you clicked on - then don't place if it's another building.
// spawn a new object at the intersection point
//%pos, %class, %team
BldEventManager.postEvent("_RequestBuilding", %pos TAB %class TAB %client.team);
}
}

This comic about black cats will almost certainly make you cry
Jenny Jinya brought us the ‘Good Boy’ comic that pretty much wrecked our lives.
In it, a puppy who’s been abandoned by the side of the road is visited by death, saying it’s his time to go.
He asks death if he’s been a bad boy and that was why he was left alone, and death decides all the love the little pup has to give shouldn’t go to waste.
So, when a person in hospital passes away, death makes sure that the dog is the first thing they see, making their transition a little easier and giving the dog people who he can love and be loved by.
If you thought that was heartbreaking, though, you’re going to be absolutely devastated by the recent comic Jinya has released.
 Take a look.
Yup, straight in the feels. We did warn you.

It’s not just about making us all cry, though. Jinya is using the comic to highlight how black cats are discriminated against, and can face cruelty and neglect as a result of superstitions.
In an Instagram post of the comic, she said: ‘Even in 2019, you still hear of black cats being associated with superstitions, witches, black magic and such.
‘Black shelter pets are less likely to be adopted than pets of other colors. They still face so much hate nowadays and the more I read about this topic, the sadder I get.’
It’s true. The RSPCA say that black cats are the hardest to find homes for.
Instagram allegedly plays a role too, with photographer Emma O’Brien finding that some people didn’t want black cats or dogs because they believed they wouldn’t photograph as well for their social media.
At least we’re crying our eyes out for a good cause.
Another warning, though. Jenny Jinya teased a sequel to this comic just yesterday, so don’t put the tissues away just yet.

title: Migrating CFMX from windows to Linux
tags: []
status: publish
type: post
published: true
meta: {}
---
This was a thread from a while back n the CFDJ list in which someone asked what needed to be considered when migrating CFMX instance running on JRun from a windows server to a Linux box. I have summarised the findings for posterity:
- Files are case sensitive on unix, hence Application.cfm, OnRequestEnd.cfm and all cfincludes must have the exact case.
- The same applies to  and , however there is a module for Apache that allows you to fix that potential pitfall.
- No COM support
- Any C++ CFX tags would need to be recompiled for Linux
- Verity Support is limited to certain Linux distros see the release notes
- talking to an MS Access database is trickier.


Research Interests
Throughout my Ph.D., I conduct research on the
Sensing and Computing for Edge AI Systems. My research involves the following three directions:
-
Sensor-Specific Data Processing
I have been working on the data processing algorithms on a variety of sensors, including RGB-D cameras, IMUs, and mmWave radars. Applications include object detection, object tracking, activity recognition and vital sign sensing.
-
Machine Learning Algorithms for Real-World Data
Due to the imbalanced data distribution, data insufficiency and domain shift, machine learning using the real-world data is highly challenging. I have been working on corresponding solutions on federated learning, long-tailed learning, few-shot learning and domain adaptation, etc.
-
High-Performance Inference on the Edge
The deployment of the deep learning models on edge devices is the last mile of building an AIoT application. My studies aim to accelerate the on-device inference of neural networks via hardware-aware tensor program generation using both intra-operator and inter-operator optimizations.
