• Filesystem synchronization library?

  - by IsaacB

  Hi, I've got 10 GB of files to back up daily to another site. The client is way out in the country so bandwidth is an issue. Does anyone know of any existing software or libraries out there that help with keeping a folder with its files synchronized across a slow link, that is it only sends files across if they have changed? Some kind of hash checking would be nice, too, to at least confirm the two sides are the same. I don't mind paying some money for it, seeing as how it might take me several weeks to a month to implement something decent on my own. I just don't want to re-invent the wheel, here. BTW it is a windows shop (they have an in house windows IT guy) so windows is preferred. I also have 10 GB of SQL Server 2000 databases to go across. Is the SQL server replication mode reliable? Thanks!

• problems in trying ieee 802.15.4 working from msk

  - by asel

  Hi, i took a msk code from dsplog.com and tried to modify it to test the ieee 802.15.4. There are several links on that site for ieee 802.15.4. Currently I am getting simulated ber results all approximately same for all the cases of Eb_No values. Can you help me to find why? thanks in advance! clear PN = [ 1 1 0 1 1 0 0 1 1 1 0 0 0 0 1 1 0 1 0 1 0 0 1 0 0 0 1 0 1 1 1 0; 1 1 1 0 1 1 0 1 1 0 0 1 1 1 0 0 0 0 1 1 0 1 0 1 0 0 1 0 0 0 1 0; 0 0 1 0 1 1 1 0 1 1 0 1 1 0 0 1 1 1 0 0 0 0 1 1 0 1 0 1 0 0 1 0; 0 0 1 0 0 0 1 0 1 1 1 0 1 1 0 1 1 0 0 1 1 1 0 0 0 0 1 1 0 1 0 1; 0 1 0 1 0 0 1 0 0 0 1 0 1 1 1 0 1 1 0 1 1 0 0 1 1 1 0 0 0 0 1 1; 0 0 1 1 0 1 0 1 0 0 1 0 0 0 1 0 1 1 1 0 1 1 0 1 1 0 0 1 1 1 0 0; 1 1 0 0 0 0 1 1 0 1 0 1 0 0 1 0 0 0 1 0 1 1 1 0 1 1 0 1 1 0 0 1; 1 0 0 1 1 1 0 0 0 0 1 1 0 1 0 1 0 0 1 0 0 0 1 0 1 1 1 0 1 1 0 1; 1 0 0 0 1 1 0 0 1 0 0 1 0 1 1 0 0 0 0 0 0 1 1 1 0 1 1 1 1 0 1 1; 1 0 1 1 1 0 0 0 1 1 0 0 1 0 0 1 0 1 1 0 0 0 0 0 0 1 1 1 0 1 1 1; 0 1 1 1 1 0 1 1 1 0 0 0 1 1 0 0 1 0 0 1 0 1 1 0 0 0 0 0 0 1 1 1; 0 1 1 1 0 1 1 1 1 0 1 1 1 0 0 0 1 1 0 0 1 0 0 1 0 1 1 0 0 0 0 0; 0 0 0 0 0 1 1 1 0 1 1 1 1 0 1 1 1 0 0 0 1 1 0 0 1 0 0 1 0 1 1 0; 0 1 1 0 0 0 0 0 0 1 1 1 0 1 1 1 1 0 1 1 1 0 0 0 1 1 0 0 1 0 0 1; 1 0 0 1 0 1 1 0 0 0 0 0 0 1 1 1 0 1 1 1 1 0 1 1 1 0 0 0 1 1 0 0; 1 1 0 0 1 0 0 1 0 1 1 0 0 0 0 0 0 1 1 1 0 1 1 1 1 0 1 1 1 0 0 0; ]; N = 5*10^5; % number of bits or symbols fsHz = 1; % sampling period T = 4; % symbol duration Eb_N0_dB = [0:10]; % multiple Eb/N0 values ct = cos(pi*[-T:N*T-1]/(2*T)); st = sin(pi*[-T:N*T-1]/(2*T)); for ii = 1:length(Eb_N0_dB) tx = []; % MSK Transmitter ipBit = round(rand(1,N/32)*15); for k=1:length(ipBit) sym = ipBit(k); tx = [tx PN((sym+1),1:end)]; end ipMod = 2*tx - 1; % BPSK modulation 0 -> -1, 1 -> 1 ai = kron(ipMod(1:2:end),ones(1,2*T)); % even bits aq = kron(ipMod(2:2:end),ones(1,2*T)); % odd bits ai = [ai zeros(1,T) ]; % padding with zero to make the matrix dimension match aq = [zeros(1,T) aq ]; % adding delay of T for Q-arm % MSK transmit waveform xt = 1/sqrt(T)*[ai.*ct + j*aq.*st]; % Additive White Gaussian Noise nt = 1/sqrt(2)*[randn(1,N*T+T) + j*randn(1,N*T+T)]; % white gaussian noise, 0dB variance % Noise addition yt = xt + 10^(-Eb_N0_dB(ii)/20)*nt; % additive white gaussian noise % MSK receiver % multiplying with cosine and sine waveforms xE = conv(real(yt).*ct,ones(1,2*T)); xO = conv(imag(yt).*st,ones(1,2*T)); bHat = zeros(1,N); bHat(1:2:end) = xE(2*T+1:2*T:end-2*T); % even bits bHat(2:2:end) = xO(3*T+1:2*T:end-T); % odd bits result=zeros(16,1); chiplen=32; seqstart=1; recovered = []; while(seqstart<length(bHat)) A = bHat(seqstart:seqstart+(chiplen-1)); for j=1:16 B = PN(j,1:end); result(j)=sum(A.*B); end [value,index] = max(result); recovered = [recovered (index-1)]; seqstart = seqstart+chiplen; end; %# create binary string - the 4 forces at least 4 bits bstr1 = dec2bin(ipBit,4); bstr2 = dec2bin(recovered,4); %# convert back to numbers (reshape so that zeros are preserved) out1 = str2num(reshape(bstr1',[],1))'; out2 = str2num(reshape(bstr2',[],1))'; % counting the errors nErr(ii) = size(find([out1 - out2]),2); end nErr/(length(ipBit)*4) % simulated ber theoryBer = 0.5*erfc(sqrt(10.^(Eb_N0_dB/10))) % theoretical ber

• Spring Data MongoDB Date between two Dates

  - by sics

  i'm using Spring Data for MongoDB and got the following classes class A { List<B> b; } class B { Date startDate; Date endDate; } when i save an object of A it gets persisted like { "_id" : "DQDVDE000VFP8E39", "b" : [ { "startDate" : ISODate("2009-10-05T22:00:00Z"), "endDate" : ISODate("2009-10-29T23:00:00Z") }, { "startDate" : ISODate("2009-11-01T23:00:00Z"), "endDate" : ISODate("2009-12-30T23:00:00Z") } ] } Now i want to query the db for documents matching entries in b where a given date is between startDate and endDate. Query query = new Query(Criteria.where("a").elemMatch( Criteria.where("startDate").gte(date) .and("endDate").lte(date) ); Which results in the following mongo query: { "margins": { "$elemMatch": { "startDate" : { "$gte" : { "$date" : "2009-11-03T23:00:00.000Z"}}, "endDate" : { "$lte" : { "$date" : "2009-11-03T23:00:00.000Z"}} } } } but returns no resulting documents. Does anybody know what i'm doing wrong? I don't get it... Thank you very much in advance!!

• Agilent E4426B signal generator locks up during multiple GPIB *SAV operations

  - by aspiehler

  I have a test fixture with an Agilent E4426B RF signal generator connected to a PC via a National Instrument Ethernet-to-GPIB bridge. My software is attempting to sanitize the instrument by presetting it and then saving the current state to all of the memory locations writable via the standard SCPI command "*SAV x,y". The loop works to a point, but eventually the instrument responds with an error and continuously displays the "L" icon on the front display and a "Remote preset" message at the bottom. At that point it won't respond to any more remote commands and I have to either cycle power or press LOCAL, then PRESET at which point it takes about 3 minutes to finish presetting. At that point the "L" icon is still present and and the next GPIB command sent to the instrument causes it to report a -113 error (undefined header) in the instrument error queue. I fired up NI spy to see what was happening, and found that the error was happening at the same point in the loop - "*SAV 6,2" in this case. From NI Spy: Send (0, 0x0017, "*SAV 6,2", 8 (0x8), NLend (0,0x01)) Process ID: 0x00000520 Thread ID: 0x00000518 ibsta:0xc168 iberr: 6 ibcntl: 2(0x2) And here's the code from the instrument driver: int CHP_E4426b::Erase() { if ((m_StatusCode = Initialize()) != GPIB_SUCCESS) // basically just sends "*RST" return m_StatusCode; m_SaveState = "*SAV %d, %d"; for (int i=0; i < 10; i++) for (int j=0; j < 100; j++) { sprintf(m_CmdString, m_SaveState, j, i); if ((m_StatusCode = Send(m_CmdString, strlen(m_CmdString))) != GPIB_SUCCESS) return m_StatusCode; } return GPIB_SUCCESS; } I tried putting a small Sleep() delay (10-20 ms) at the end of the inner loop, and to my surprise it caused the error to show up earlier rather than later. 10 ms caused the loop to error out at 44,1 and 20 ms was even sooner. I've already eliminated faulty cabling or the instrument as the culprit. This same type of sequence works without any error on a higher end signal generator, so I'm tempted to chalk this up to a bug in the instrument's firmware.

• CUDA threads output different value

  - by kar

  HAi, I wrote a cuda program , i have given the kernel function below. The device memory is allocated through CUDAMalloc(); the value of *md is 10; __global__ void add(int *md) { int x,oper=2; x=threadIdx.x; * md = *md*oper; if(x==1) { *md = *md*0; } if(x==2) { *md = *md*10; } if(x==3) { *md = *md+1; } if(x==4) { *md = *md-1; } } executed the above code add<<<1,5>>(*md) , add<<<1,4>>>(*md) for <<<1,5>>> the output is 19 for <<<1,4>>> the output is 21 1) I have doubt that cudaMalloc() will allocate in device main memory? 2) Why the last thread alone is executed always in the above program? Thank you

• Multiline editable textarea in SVG

  - by Timo

  I'm trying to implement multiline editable textfield in SVG. I have the following code in http://jsfiddle.net/ca4d3/ : <svg width="1000" height="1000" overflow="scroll"> <g transform="rotate(5)"> <rect width="300" height="400" fill="#22DD22" fill-opacity="0.5"/> </g> <foreignObject x="10" y="10" overflow="visible" width="10000" height="10000" requiredFeatures="http://www.w3.org/TR/SVG11/feature#Extensibility"> <p style="display:table-cell;padding:10px;border:1px solid red; background-color:white;opacity:0.5;font-family:Verdana; font-size:20px;white-space: pre; word-wrap: normal; overflow: visible; overflow-y: visible; overflow-x:visible;" contentEditable="true" xmlns="http://www.w3.org/1999/xhtml"> Write here some text. Be smart and select some word. If you wanna be really COOL, paste here something cool! </p> </foreignObject> </svg> In newest Chrome, Safari and Firefox the code works in some way, but in Opera and IE 9 not. The goal is that: 0) Works in newest Chrome, Safari, Firefox, Opera and IE and if ever possible in some pads. 1) White-spaces are preserved and text wraps only on newline char (works in Chrome, Safari and Firefox, but not in Opera and IE 9 *). 2) The textfield is editable (in the same reliable and stabile way as textareas and contenteditable p elements in html) and height and width is expanded to fit text (works in Chrome, Safari and Firefox, but not in Opera and IE 9 *). 3) Texfield can be transformed (rotated, skewed, translated) while maintaining text editability (Tested rotation, but not work in any browser *). EDIT: Foreignobject rotation works on Firefox 15.0.1, but not in Safari 5.1.7 (6534.57.2), Chrome 22.0.1229.79, Opera 12.02, IE 9. Tested on Mac OS X 10.6.8. 4) Textfield can be clipped and masked while not necessarily maintaining text editability (not yet tested). *) using above code These all can be achieved using Flash, but Flash has so severe problems that it is not suitable for my purposes (after every little change in code, all have to be compiled again using Flex, which is slow, font size has limits, tracking technique is pixeloriented, not relative to em size etc.) and there still are differences across platforms. And I want to give a try to SVG! GUESTION: Can I achieve my goals 0-4 with current SVG support in browsers? Is coming SVG 2.0 for some help in this case? EDIT: Changed display:table to display:table-cell (and added new jsfiddle), because display:table made the field to loses focus when pressed arrow-up on first text row.

• SQL Server: collect values in an aggregation temporarily and reuse in the same query

  - by Erwin Brandstetter

  How do I accumulate values in t-SQL? AFAIK there is no ARRAY type. I want to reuse the values like demonstrated in this PostgreSQL example using array_agg(). SELECT a[1] || a[i] AS foo ,a[2] || a[5] AS bar -- assuming we have >= 5 rows for simplicity FROM ( SELECT array_agg(text_col ORDER BY text_col) AS a ,count(*)::int4 AS i FROM tbl WHERE id between 10 AND 100 ) x How would I best solve this with t-SQL? Best I could come up with are two CTE and subselects: ;WITH x AS ( SELECT row_number() OVER (ORDER BY name) AS rn ,name AS a FROM #t WHERE id between 10 AND 100 ), i AS ( SELECT count(*) AS i FROM x ) SELECT (SELECT a FROM x WHERE rn = 1) + (SELECT a FROM x WHERE rn = i) AS foo ,(SELECT a FROM x WHERE rn = 2) + (SELECT a FROM x WHERE rn = 5) AS bar FROM i Test setup: CREATE TABLE #t( id INT PRIMARY KEY ,name NVARCHAR(100)) INSERT INTO #t VALUES (3 , 'John') ,(5 , 'Mary') ,(8 , 'Michael') ,(13, 'Steve') ,(21, 'Jack') ,(34, 'Pete') ,(57, 'Ami') ,(88, 'Bob') Is there a simpler way?

• iPhone status bar orientation with opengl

  - by sfider

  I have opengl only view that displays in portrait and landscape mode using projection matrix (view's transformation is identity all the time). I need to show status bar with proper orientation. I do this by setting status bar orientation property in UIApplication and changing frame of opengl view so the view won't go under status bar. When I change from landscape to portrait (landscape is the initial state) view's frame is set to (0, 20, 320, 460) and stays like this. However view appears to be translated by (-10, -10). It seems that I did change the size of view but couldn't move it. Weird things are: initialy view is full screen, I change it to (0, 0, 300, 480) (landscape with status bar) and it works then, it doesn't work when I try to chenge it for the second time (portrait with status bar) frame property of the view shows that view is placed correctly Any thoughts on what can by the problem?

• Saving to SharedPreferences from custom DialogPreference

  - by Ronnie

  I've currently got a preferences screen, and I've created a custom class that extends DialogPreference and is called from within my Preferences. My preferences data seems store/retrieve from SharedPreferences without an issue, but I'm trying to add 2 more sets of settings from the DialogPreference. Basically I have two issues that I have not been able to find. Every site I've seen gives me the same standard info to save/restore data and I'm still having problems. Firstly I'm trying to save a username and password to my SharedPreferences (visible in the last block of code) and if possibly I'd like to be able to do it in the onClick(). My preferences XML that calls my DialogPreference: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory> <com.rone.optusmon.AccDialog android:key="AccSettings" android:title="Account Settings" android:negativeButtonText="Cancel" android:positiveButtonText="Save" /> </PreferenceCategory> </PreferenceScreen> My Preference Activity Class: package com.rone.optusmon; import android.app.AlertDialog; import android.content.Context; import android.content.DialogInterface; import android.os.Bundle; import android.preference.Preference; import android.preference.Preference.OnPreferenceClickListener; import android.preference.PreferenceActivity; import android.view.KeyEvent; public class EditPreferences extends PreferenceActivity { Context context = this; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); } } My Custom DialogPreference Class file: package com.rone.optusmon; import android.content.Context; import android.content.DialogInterface; import android.content.SharedPreferences; import android.preference.DialogPreference; import android.preference.PreferenceManager; import android.text.method.PasswordTransformationMethod; import android.util.AttributeSet; import android.view.View; import android.widget.CheckBox; import android.widget.CompoundButton; import android.widget.CompoundButton.OnCheckedChangeListener; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.TextView; import android.widget.Toast; public class AccDialog extends DialogPreference implements DialogInterface.OnClickListener { private TextView mUsername, mPassword; private EditText mUserbox, mPassbox; CharSequence mPassboxdata, mUserboxdata; private CheckBox mShowchar; private Context mContext; private int mWhichButtonClicked; public AccDialog(Context context, AttributeSet attrs) { super(context, attrs); mContext = context; } @Override protected View onCreateDialogView() { @SuppressWarnings("unused") LinearLayout.LayoutParams params; LinearLayout layout = new LinearLayout(mContext); layout.setOrientation(LinearLayout.VERTICAL); layout.setPadding(10, 10, 10, 10); layout.setBackgroundColor(0xFF000000); mUsername = new TextView(mContext); mUsername.setText("Username:"); mUsername.setTextColor(0xFFFFFFFF); mUsername.setPadding(0, 8, 0, 3); mUserbox = new EditText(mContext); mUserbox.setSingleLine(true); mUserbox.setSelectAllOnFocus(true); mPassword = new TextView(mContext); mPassword.setText("Password:"); mPassword.setTextColor(0xFFFFFFFF); mPassbox = new EditText(mContext); mPassbox.setSingleLine(true); mPassbox.setSelectAllOnFocus(true); mShowchar = new CheckBox(mContext); mShowchar.setOnCheckedChangeListener(mShowchar_listener); mShowchar.setText("Show Characters"); mShowchar.setTextColor(0xFFFFFFFF); mShowchar.setChecked(false); if(!mShowchar.isChecked()) { mPassbox.setTransformationMethod(new PasswordTransformationMethod()); } layout.addView(mUsername); layout.addView(mUserbox); layout.addView(mPassword); layout.addView(mPassbox); layout.addView(mShowchar); return layout; // Access default SharedPreferences SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); } public void onClick(DialogInterface dialog, int which) { mWhichButtonClicked = which; // if statement to set save/cancel button roles if (mWhichButtonClicked == -1) { Toast.makeText(mContext, "Save was clicked", Toast.LENGTH_SHORT).show(); mUserboxdata = mUserbox.getText(); mPassboxdata = mPassbox.getText(); // Save user preferences SharedPreferences settings = getDefaultSharedPreferences(this); SharedPreferences.Editor editor = settings.edit(); editor.putString("usernamekey", (String) mUserboxdata); editor.putString("passwordkey", (String) mPassboxdata); } else { Toast.makeText(mContext, "Cancel was clicked", Toast.LENGTH_SHORT).show(); } } } In my SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); line, Eclipse says "The method getDefaultSharedPreferences(AccDialog) is undefined for the type AccDialog". I've attempted to change the context to my preferences class, use a blank context and I've also tried naming my SharedPrefs and using "getSharedPreferences()" as well. I'm just not sure exactly what I'm doing here. As I'm quite new to Java/Android/coding in general, could you please be as detailed as possible with any help, eg. which of my files I need to write the code in and whereabouts in that file should I write it (i.e. onCreate(), onClick(), etc) Edit: I will need to the preferences to be Application-wide accessible, not activity-wide. Thanks

• precompile App_LocalResources in Visual Studio

  - by jazbit

  My web-application project (not "web-site" project) is translated to 15 different languages using the ASP.NET's built-in resource engine (I have tons of *.aspx.resx file in the "App_LocalREsources" folder). All these resources are precompiled by ASP.NET when I first launch the application and it takes a LOT of time. A LOT. 5-10 minutes. I have to wait 5-10 minutes every time I make soe tiny change to my code to see how it works. Is there any way to compile these resource in Visual Studio? Changing the "Build Action" for all these resx-files to "Embedded resource" does not work :( (or I'm doing it wrong?) PS. I know I can write a batch file that will launch aspnet_compiler.exe and manually compile the app with all the resources, but thats a "hack". I need a documented "Visual Studio"-way to achieve this. Cause I have a setup-project for this app in the same solution, that picks up the "project output" of this web-app (and it won't pick-up any manually precompiled files I made)

• MySQL - How To Avoid Repair With Keycache?

  - by dvancouver

  I have had some experience with optimizing the my.cnf file but my database has around 4 million records (MyISAM). I am trying to restore from a mysqldump but every time I do I eventually get the dreaded "Repair With Keycache", that may take days. Is there anyway to get past this and let it roll as "Repair By Sorting"? I have 2GB RAM, Dual Cores, lots of extra hard-drive space. Snip out of my.cnf: set-variable = max_connections=650 set-variable = key_buffer=256M set-variable = myisam_sort_buffer_size=64M set-variable = join_buffer=1M set-variable = record_buffer=1M set-variable = sort_buffer_size=2M set-variable = read_buffer_size=2M set-variable = query_cache_size=32M set-variable = table_cache=1024 set-variable = thread_cache_size=256 set-variable = wait_timeout=7200 set-variable = connect_timeout=10 set-variable = max_allowed_packet=16M set-variable = max_connect_errors=10 set-variable = thread_concurrency=8

• Choosing a scripting language for game and implementing it

  - by Radius

  Hello, I am currently developing a 3D Action/RPG game in C++, and I would like some advice in choosing a scripting language to program the AI of the game. My team comes from a modding background, and in fact we are still finishing work on a mod of the game Gothic. In that game (which we also got our inspiration from) the language DAEDALUS (created by Piranha Bytes, the makers of the game) is used. Here is a full description of said language. The main thing to notice about this is that it uses instances moreso than classes. The game engine is closed, and so one can only guess about the internal implementation of this language, but the main thing I am looking for in a scripting language (which ideally would be quite similar but preferably also more powerful than DAEDALUS) is the fact that there are de facto 3 'separations' of classes - ie classes, instances and (instances of instances?). I think it will be easier to understand what I want if I provide an example. Take a regular NPC. First of all you have a class defined which (I understand) mirrors the (class or structure) inside the engine: CLASS C_NPC { VAR INT id ; // absolute ID des NPCs VAR STRING name [5] ; // Namen des NPC VAR STRING slot ; VAR INT npcType ; VAR INT flags ; VAR INT attribute [ATR_INDEX_MAX] ; VAR INT protection [PROT_INDEX_MAX]; VAR INT damage [DAM_INDEX_MAX] ; VAR INT damagetype ; VAR INT guild,level ; VAR FUNC mission [MAX_MISSIONS] ; var INT fight_tactic ; VAR INT weapon ; VAR INT voice ; VAR INT voicePitch ; VAR INT bodymass ; VAR FUNC daily_routine ; // Tagesablauf VAR FUNC start_aistate ; // Zustandsgesteuert // ********************** // Spawn // ********************** VAR STRING spawnPoint ; // Beim Tod, wo respawnen ? VAR INT spawnDelay ; // Mit Delay in (Echtzeit)-Sekunden // ********************** // SENSES // ********************** VAR INT senses ; // Sinne VAR INT senses_range ; // Reichweite der Sinne in cm // ********************** // Feel free to use // ********************** VAR INT aivar [50] ; VAR STRING wp ; // ********************** // Experience dependant // ********************** VAR INT exp ; // EXerience Points VAR INT exp_next ; // EXerience Points needed to advance to next level VAR INT lp ; // Learn Points }; Then, you can also define prototypes (which set some default values). But how you actually define an NPC is like this: instance BAU_900_Ricelord (Npc_Default) //Inherit from prototype Npc_Default { //-------- primary data -------- name = "Ryzowy Ksiaze"; npctype = NPCTYPE_GUARD; guild = GIL_BAU; level = 10; voice = 12; id = 900; //-------- abilities -------- attribute[ATR_STRENGTH] = 50; attribute[ATR_DEXTERITY] = 10; attribute[ATR_MANA_MAX] = 0; attribute[ATR_MANA] = 0; attribute[ATR_HITPOINTS_MAX]= 170; attribute[ATR_HITPOINTS] = 170; //-------- visuals -------- // animations Mdl_SetVisual (self,"HUMANS.MDS"); Mdl_ApplyOverlayMds (self,"Humans_Arrogance.mds"); Mdl_ApplyOverlayMds (self,"HUMANS_DZIDA.MDS"); // body mesh ,bdytex,skin,head mesh ,headtex,teethtex,ruestung Mdl_SetVisualBody (self,"Hum_Body_CookSmith",1,1,"Hum_Head_FatBald",91 , 0,-1); B_Scale (self); Mdl_SetModelFatness(self,2); fight_tactic = FAI_HUMAN_STRONG; //-------- Talente -------- Npc_SetTalentSkill (self,NPC_TALENT_1H,1); //-------- inventory -------- CreateInvItems (self, ItFoRice,10); CreateInvItem (self, ItFoWine); CreateInvItems(self, ItMiNugget,40); EquipItem (self, Heerscherstab); EquipItem (self, MOD_AMULETTDESREISLORDS); CreateInvItem (self, ItMi_Alchemy_Moleratlubric_01); //CreateInvItem (self,ItKey_RB_01); EquipItem (self, Ring_des_Lebens); //-------------Daily Routine------------- daily_routine = Rtn_start_900; }; FUNC VOID Rtn_start_900 () { TA_Boss (07,00,20,00,"NC_RICELORD"); TA_SitAround (20,00,24,00,"NC_RICELORD_SIT"); TA_Sleep (24,00,07,00,"NC_RICEBUNKER_10"); }; As you can see, the instance declaration is more like a constructor function, setting values and calling functions from within. This still wouldn't pose THAT much of a problem, if not for one more thing: multiple copies of this instance. For example, you can spawn multiple BAU_900_Ricelord's, and each of them keeps track of its own AI state, hitpoints etc. Now I think the instances are represented as ints (maybe even as the id of the NPC) inside the engine, as whenever (inside the script) you use the expression BAU_900_Ricelord it can be only assigned to an int variable, and most functions that operate on NPCs take that int value. However to directly modify its hitpoints etc you have to do something like var C_NPC npc = GetNPC(Bau_900_Ricelord); npc.attribute[ATR_HITPOINTS] = 10; ie get the actual C_NPC object that represents it. To finally recap - is it possible to get this kind of behaviour in any scripting languages you know of, or am I stuck with having to make my own? Or maybe there is an even better way of representing NPC's and their behaviours that way. The IDEAL language for scripting for me would be C#, as I simply adore that language, but somehow I doubt it is possible or indeed feasible to try and implement a similar kind of behaviour in C#. Many thanks

• Generating a error code per property in Hibernate validator

  - by Mike Q

  Hi all, I am looking at using hibernate validator for a requirement of mine. I want to validate a bean where properties may have multiple validation checks. e.g. class MyValidationBean { @NotNull @Length( min = 5, max = 10 ) private String myProperty; } But if this property fails validation I want a specific error code to be associated with the ConstraintViolation, regardless of whether it failed because of @Required or @Length, although I would like to preserve the error message. class MyValidationBean { @NotNull @Length( min = 5, max = 10 ) @ErrorCode( "1234" ) private String myProperty; } Something like the above would be good but it doesn't have to be structured exactly like that. I can't see a way to do this with hibernate validator. Is it possible? Thanks.

• Mac OS X 10.9 with GCC 4.7.3, stdlib.h: no such file or directory

  - by Leon Kaihua Li

  I'm doing some development with C++ on Mac OS. The code worked fine on Mac OS 10.8.3/10.8.4, with GCC 4.7.3. However recently I upgraded my OS to Mavericks 10.9 and Xcode 5.0. I find that when I try to compile my code, both gcc/g++/clang responds with: *******.C:1:** stdlib.h:no such file or directory *******.C:2:** iostream.h:no such file or directory Since I'm not familiar with Mac OS(My working platform is openSUSE), what can I do for it? will it help if I install "Command Line Tools" from Xcode? Or is there anyway that I could re-build the include index? Include dir of GCC is /opt/local/include/gcc47 and it seems there is a stdlib.h in it. The path is /opt/local/include/gcc47/c++/tr1/ Please help me, and thank you very much.

  I need some help in settingup/installing and configuring nginx LEMP stack on a fresh new VPS i have. The specs of the CentOS 5.7 VPS are 2GB DDR3 ECC RAM(4GB burst), 1 core 1.5Ghz(3Ghz burst) and 100GB RAID 10 storage, unmetered bandwidth @ 100Mpbs all for a whopping $25/month(unbeatable, yeah i know :) Anyways i have followed this LEMP(will also need MySQL and PHP) stack guide on linode http://library.linode.com/lemp-guides/centos-5 but basically what i want is to be able to host multiple website on this webserver after everything is setup. I am used to using DirectAdmin control panel on other server and want to have things setup so i can host multiple websites...mostly wordpress and drupal themes. Lets say 10 websites on this nginx web server. So can someone please help me on what i need to do to take "full" advantage of nginx power and performance, while been able to easily manage these multiple websites (wordpress and drupal themes)?

• do I need to use partial?

By way of a sample table, I have (with consecutive identical values blanked out for readability): rdate rtime rid rsub rval ------------------------------------- 2010-01-01 00.00.00 1 1 10 2 20 2 1 30 2 40 01.00.00 1 1 50 2 60 2 1 70 2 80 02.00.00 1 1 90 2 100 2010-01-02 00.00.00 1 1 999 I can get the sums I want with: select rdate,rtime,rid, sum(rval) as rsum from xx where rdate = '2010-06-01' group by rdate,rtime,rid which gives me: rdate rtime rid rsum ------------------------------- 2010-01-01 00.00.00 1 30 (10+20) 2 70 (30+40) 01.00.00 1 110 (50+60) 2 150 (70+80) 02.00.00 1 190 (90+100) as expected. Now what I want is the query that will also average those values across the time dimension, giving me: rdate rtime ravgsum ---------------------------- 2010-01-01 00.00.00 50 ((30+70)/2) 01.00.00 130 ((110+150)/2) 02.00.00 190 ((190)/1) I'm using DB2 for z/OS but I'd prefer standard SQL if possible.

• About fork system call and global variables

  - by lurks

  I have this program in C++ that forks two new processes: #include <pthread.h> #include <iostream> #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> #include <cstdlib> using namespace std; int shared; void func(){ extern int shared; for (int i=0; i<10;i++) shared++; cout<<"Process "<<getpid()<<", shared " <<shared<<", &shared " <<&shared<<endl; } int main(){ extern int shared; pid_t p1,p2; int status; shared=0; if ((p1=fork())==0) {func();exit(0);}; if ((p2=fork())==0) {func();exit(0);}; for(int i=0;i<10;i++) shared++; waitpid(p1,&status,0); waitpid(p2,&status,0);; cout<<"shared variable is: "<<shared<<endl; cout<<"Process "<<getpid()<<", shared " <<shared<<", &shared " <<&shared<<endl; } The two forked processes make an increment on the shared variables and the parent process does the same. As the variable belongs to the data segment of each process, the final value is 10 because the increment is independent. However, the memory address of the shared variables is the same, you can try compiling and watching the output of the program. How can that be explained ? I cannot understand that, I thought I knew how the fork() works, but this seems very odd.. I need an explanation on why the address is the same, although they are separate variables.

• Why does LINQ-to-SQL Paging fail inside a function?

  - by ssg

  Here I have an arbitrary IEnumerable<T>. And I'd like to page it using a generic helper function instead of writing Skip/Take pairs every time. Here is my function: IEnumerable<T> GetPagedResults<T>(IEnumerable<T> query, int pageIndex, int pageSize) { return query.Skip((pageIndex - 1) * pageSize).Take(pageSize); } And my code is: result = GetPagedResults(query, 1, 10).ToList(); This produces a SELECT statement without TOP 10 keyword. But this code below produces the SELECT with it: result = query.Skip((pageIndex - 1) * pageSize).Take(pageSize).ToList(); What am I doing wrong in the function?

• IF statement error in tcsh

  - by kaustav datta

  Having trouble executing an IF statement through tcsh. This works FINE for me - #!/bin/bash if echo `cal|tail -6|sed -e 's/^.\{3\}//' -e 's/.\{3\}$//' |tr -s '[:blank:]' '\n' | head -11|tail -10|tr -s '\n' ' '`|grep -w `date "+%e"` then echo "present" else echo "absent" fi This is the PROBLEM - #!/bin/tcsh if echo `cal|tail -6|sed -e 's/^.\{3\}//' -e 's/.\{3\}$//' |tr -s '[:blank:]' '\n' | head -11|tail -10|tr -s '\n' ' '`|grep -w `date "+%e"` then echo "present" else echo "absent" endif Getting this error- if: Expression Syntax. then: Command not found. I really need this to run using "tcsh"

• Computationally simple Pseudo-Gaussian Distribution with varying mean and standard deviation?

  - by mstksg

  This picture from wikipedia has a nice example of the sort of functions I'd ideally like to generate http://en.wikipedia.org/wiki/File:Normal_Distribution_PDF.svg Right now I'm using the Irwin-Hall Distribution, which is more or less a Polynomial approximation of the Gaussian distribution...basically, you use uniform random number generator and iterate it x times, and take the average. The more iterations, the more like a Gaussian Distribution it is. It's pretty nice; however I'd like to be able to have one where I can vary the mean. For example, let's say I wanted a number between the range 0 and 10, but around 7. Like, the mean (if I repeated this function multiple times) would turn out to be 7, but the actual range is 0-10. Is there one I should look up, or should I work on doing some fancy maths with standard Gaussian Distributions?
