  • Best way to get photoshop to optimise 35 related pictures for fast transmission

    - by thenerd
    I have 35 pictures taken from a stationary camera aimed at a lightbox in which an object is placed, rotated at 10 degrees in each picture. If I cycle through the pictures quickly, the image looks like it is rotating. If I wished to 'rotate' the object in a browser but wanted to transmit as little data as possible for this, I thought it might be a good idea to split the picture into 36 pictures, where 1 picture is any background the images have in common, and 35 pictures minus the background, just showing the things that have changed. Do you think this approach will work? Is there a better route? How would I achieve this in photoshop?

  • how to fast compute distance between high dimension vectors

    - by chyojn
    assume there are three group of high dimension vectors: {a_1, a_2, ..., a_N}, {b_1, b_2, ... , b_N}, {c_1, c_2, ..., c_N}. each of my vector can be represented as: x = a_i + b_j + c_k, where 1 <=i, j, k <= N. then the vector is encoded as (i, j, k) wich is then can be decoded as x = a_i + b_j + c_k. my question is, if there are two vector: x = (i_1, j_1, k_1), y = (i_2, j_2, k_2), is there a method to compute the euclidian distance of these two vector without decode x and y.

  • Want to check fields for data fast.

    - by Tom
    We have a database setup that consists of two parts: a static structure, and dynamic additions. For each database, the dynamic can be different, and sometimes we don't have data for all the dynamic fields. Rigt now, we check for empties by looking at the total count of records in the entire table, but we want to move to a more refined method of checking for empties if possible. Is it possible to quickly check through several hundred fields and see which ones are empty and which ones are populated?

  • Super fast getimagesize in php

    - by Sir Lojik
    Hi all, im trying to get image size(DIMENSIONS) of hundreds of remote images and getimagesize is way too slow. ive done some reading and found out the quickest way would be to use get_file_contents to read a certain aount of bytes from the images and examining the size within the binary data. Anyone attempted this before? How would i examine different formats. Seen any library for this? please let me know

  • Fast, cross-platform timer?

    - by dsimcha
    I'm looking to improve the D garbage collector by adding some heuristics to avoid garbage collection runs that are unlikely to result in significant freeing. One heuristic I'd like to add is that GC should not be run more than once per X amount of time (maybe once per second or so). To do this I need a timer with the following properties: It must be able to grab the correct time with minimal overhead. Calling core.stdc.time takes an amount of time roughly equivalent to a small memory allocation, so it's not a good option. Ideally, should be cross-platform (both OS and CPU), for maintenance simplicity. Super high resolution isn't terribly important. If the times are accurate to maybe 1/4 of a second, that's good enough. Must work in a multithreaded/multi-CPU context. The x86 rdtsc instruction won't work.

  • How to make your more experienced and authoritative teammates not to create 'fast temporary solution

    - by Roman
    I'm currently working on a small short-lived project. But despite the size it's complicated enough with very unclear logic. That's why it was started by more experienced developers. They work on it from time to time because it's not their main project. They made some code drafts with numerous places which 'would be rewritten in the nearest future'. After that they added several another 'temporary pieces'. And then again.. So, now the project is a mess of 'half-working' pieces of code with some hardcoded values, like file names or some constants which 'will be replaced latter with working parts'. The API is awful (nobody thinks about it actually). And it's really, really hard to do development now (for me it's the main and only project). I caught myself thinking that I spent about an hour every day just to understand again all that tricky 'temporary' things and API weaknesses. And after that hour my brain melts. I can't just say that "guys, your code smells like a trash dump". What's the correct way?

  • how do i do very fast inserts to SQL Server 2008

    - by CharlesO
    I have a project that involves recording data from a device directly into a sql table. I do very little processing in code before writing to sql server (2008 express by the way) typically i use the sqlhelper class's ExecuteNoneQuery method and pass in a stored proc name and list of parameters that the SP expects. This is very convenient, but i need a much faster way of doing this. Thanks.

  • Fast compiler error messages in Eclipse

    - by Chris Conway
    As a new Eclipse user, I am constantly annoyed by how long it takes compiler error messages to display. This is mostly only a problem for long errors that don't fit in the status bar or the "Problems" tab. But I get enough long errors in Java—especially with generics—that this is a nagging issue. (Note: The correct answer to this question is not "get better at using generics." ;-) The ways I have found to display an error are: Press Ctrl+. or execute the command "Next Annotation". The next error is highlighted and its associated message appears in the status bar (if it is short enough). The error is also highlighted in the "Problems" tab, if it is open, but the tab is not automatically brought to the top. Hover the mouse over the error. After a noticeable lag, the error message appears as a "tool tip", along with any associated "Quick Fixes." Hover the mouse over the error icon on the left side of the editing pane. After a noticeable lag, all of the error messages for that line appear as a "tool tip." Clicking on the icon brings up "Quick Fixes." What I would like is for Ctrl+. to automatically and instantly bring up the complete error message (I don't care where). Is this a configurable option? [UPDATE] @asterite's "Ctrl+. F2" is almost it. How do I make "Next Annotation, then Show Tooltip Description" a macro bound to a single keystroke?

  • fast load big object graph from DB

    - by Famos
    Hi I have my own data structure written in C# like: public class ElectricScheme { public List<Element> Elements { get; set; } public List<Net> Nets { get; set; } } public class Element { public string IdName { get; set; } public string Func { get; set; } public string Name { get; set; } public BaseElementType Type { get; set; } public List<Pin> Pins { get; set; } } public class Pin { public string IdName { get; set; } public string Name { get; set; } public BasePinType PinType { get; set; } public BasePinDirection PinDirection { get; set; } } public class Net { public string IdName { get; set; } public string Name { get; set; } public List<Tuple<Element,Pin>> ConnectionPoints { get; set; } } Where Elements count ~19000, each element contain =3 Pin, Nets count ~20000, each net contain =3 pair (Element, Pin) Parse txt (file size ~17mb) file takes 5 minutes. Serilization / Deserialization by default serializer ~3 minutes. Load from DB 20 minutes and not loaded... I use Entity Framework like public ElectricScheme LoadScheme(int schemeId) { var eScheme = (from s in container.ElectricSchemesSet where s.IdElectricScheme.Equals(schemeId) select s).FirstOrDefault(); if (eScheme == null) return null; container.LoadProperty(eScheme, "Elements"); container.LoadProperty(eScheme, "Nets"); container.LoadProperty(eScheme, "Elements.Pins"); return eScheme; } The problem is dependencies between Element and Pin... (for ~19000 elements ~95000 pins) Any ideas?

  • Looking for fast "Find in Files" program

    - by Josh McDonald
    I currently have a directory with 98,000 individual archive transaction files. I need to search those files for user input strings and have the option to open the files as it finds them or at the end of the search. I'm using Notepad++ currently and, while functional, it's quite slow. I thought about writing my own, but I am only familiar with .NET and I'm a beginner. Also, I'm not sure how efficient that would be compared to NP++. This tool would be used again and again so the dev time would definitely be worth it if it came to that. Is there some other tool out there that's already developed that would accomplish this?

  • fast way for finding GUIDs.

    - by Behrooz
    hi. I have lots(+2000) of GUIDs(in some network class) and my program must find one of them when it receives a message and do the job associated with it. the positive point is i have a hard-code generator, but the fastest way is my goal(and i don't know how to implement it). my code should do something like this: switch(received guid) { case guid1: do job 1; break; case guid2: do job 2; break; case guid3: do job 3; break; case guid4: do job 4; break; .... }

  • complex mysql rank !

    - by silversky
    I have a tb with this col: ein, los, id ... I whant to order the table by this index: win / ( win + los ) * 30 + win / SUM(win) * 70 and then to find the rank for two id's. I'm not very good on mysql, so whath I wrote it's totally wrong: $stmt=$con-prepare("SET @rk := 0"); $stmt=$con-prepare("SELECT rank, id FROM ( SELECT @rk := @rk + 1 AS rank, (win/(win+los)*30+win/SUM(win)*70) AS index, win, los, id FROM tb_name ORDER BY index DESC) as result WHERE id=? AND id=?"); $stmt - bind_param ("ii", $id1, $id2); $stmt - execute(); $stmt - bind_result($rk, $idRk); And also this query it supouse to run maybe every 5-10 sec for every user, so I'm trying to find something very, very fast. if it's necesary I could add, change, delete any column, in order to be as faster as posible.

  • Which has been the most reliable, fastest Windows C++ profiler that you have used?

    - by carleeto
    I need to profile a real time C++ app on Windows. Most of the available profilers are either terribly expensive, total overkill, or both. I don't need any .NET stuff. Since it is a real time app, I need the profiler to be as fast as possible. It would be excellent if it integrated in some way with Visual Studio 2005/2008, but that's not necessary. If this description reminds you of a profiler that you have used, I would really like to know about it. I am hoping to draw from people's use of C++ profilers on Windows to pinpoint one that will do the job. Thanks.

  • Python (pdb) - Queueing up commands to execute

    - by kpatelPro
    I am implementing a "breakpoint" system for use in my Python development that will allow me to call a function that, in essence, calls pdb.set_trace(); Some of the functionality that I would like to implement requires me to control pdb from code while I am within a set_trace context. Example: disableList = [] def breakpoint(name=None): def d(): disableList.append(name) #**** #issue 'run' command to pdb so user #does not have to type 'c' #**** if name in disableList: return print "Use d() to disable breakpoint, 'c' to continue" pdb.set_trace(); In the above example, how do I implement the comments demarked by the #**** ? In other parts of this system, I would like to issue an 'up' command, or two sequential 'up' commands without leaving the pdb session (so the user ends up at a pdb prompt but up two levels on the call stack. Thanks!

  • clicking the debug button in Eclipse will not start debug mode

    - by iHorse
    i am running Eclipse 3.5.0 on a MacBook Pro using the Android SDK. i noticed that on this particular project i am working on i cant seem to actually enter debug mode. i click the little green bug icon in the tool bar and the app starts and runs. but if i switch over to the Debug Perspective i see no indication that it is running in debug mode. furthermore i can not hit any brake points that i have set. this makes debugging code a bit hard. Other projects that i am working on don't have this issue. any ideas on what i need to change in the project to get this to work?

  • Can't set breakpoints on an auto-property setter ? Why?

    - by Cristi Diaconescu
    Apparently VS 2008 does not allow setting a breakpoint just on the setter of an auto-property. I.e. if I define an auto-property like this: public int CurrentFramesize { get; protected set; } and then try to set a breakpoint on the setter line, the whole auto-property turns breakpoint-red. This works just fine for normal properties, so any idea why auto-properties get this special (restrictive) treatment? Are they more than just syntactic sugar to normal properties with a hidden backing field?

  • "Replay" the steps needed to recreate an error

    - by David
    I am going to create a typical business application that will be used by a few hundred consultants. Normally, the consultants would be presented with an error message with a standard text. As the application will be a complicated one with lots of changes being made to it constantly I would like the following: When an error message is presented, the user has the option to "send" the error message to the developers. The developers should be able to open the incoming file in i.e. Eclipse and debug the steps of the last 10 minutes of work step by step (one line at a time if they want to). Everything should be transparent, meaning that they for example should be able to see the return values of calls to the database. Are there any solutions that offer such functionality today, my preferred language is Python or also Java. I know that there will be a huge performance hit because of such functionality, but that is acceptable as this kind of software is not performance sensitive. It would be VERY nice if the database also had a cronology so that one could query the database for values that existed at the exact time that a specific line of code was run in the application, leading up to the bug.

  • Copy object values in Visual Studio debug mode

    - by Farinha
    In Visual Studio debug mode it's possible to hover over variables to show their value and then right-click to "Copy", "Copy Expression" or "Copy Value". In case the variable is an object and not just a basic type, there's a + sign to expand and explore the object. It there a way to copy all that into the clipboard?
