• 'Binary XML' for game data?

  - by bluescrn

  I'm working on a level editing tool that saves its data as XML. This is ideal during development, as it's painless to make small changes to the data format, and it works nicely with tree-like data. The downside, though, is that the XML files are rather bloated, mostly due to duplication of tag and attribute names. Also due to numeric data taking significantly more space than using native datatypes. A small level could easily end up as 1Mb+. I want to get these sizes down significantly, especially if the system is to be used for a game on the iPhone or other devices with relatively limited memory. The optimal solution, for memory and performance, would be to convert the XML to a binary level format. But I don't want to do this. I want to keep the format fairly flexible. XML makes it very easy to add new attributes to objects, and give them a default value if an old version of the data is loaded. So I want to keep with the hierarchy of nodes, with attributes as name-value pairs. But I need to store this in a more compact format - to remove the massive duplication of tag/attribute names. Maybe also to give attributes native types, so, for example floating-point data is stored as 4 bytes per float, not as a text string. Google/Wikipedia reveal that 'binary XML' is hardly a new problem - it's been solved a number of times already. Has anyone here got experience with any of the existing systems/standards? - are any ideal for games use - with a free, lightweight and cross-platform parser/loader library (C/C++) available? Or should I reinvent this wheel myself? Or am I better off forgetting the ideal, and just compressing my raw .xml data (it should pack well with zip-like compression), and just taking the memory/performance hit on-load?

• What is the evidence that an API has exceeded its orthogonality in the context of types?

  - by hawkeye

  Wikipedia defines software orthogonality as: orthogonality in a programming language means that a relatively small set of primitive constructs can be combined in a relatively small number of ways to build the control and data structures of the language. The term is most-frequently used regarding assembly instruction sets, as orthogonal instruction set. Jason Coffin has defined software orthogonality as Highly cohesive components that are loosely coupled to each other produce an orthogonal system. C.Ross has defined software orthogonality as: the property that means "Changing A does not change B". An example of an orthogonal system would be a radio, where changing the station does not change the volume and vice-versa. Now there is a hypothesis published in the the ACM Queue by Tim Bray - that some have called the Bánffy Bray Type System Criteria - which he summarises as: Static typings attractiveness is a direct function (and dynamic typings an inverse function) of API surface size. Dynamic typings attractiveness is a direct function (and static typings an inverse function) of unit testing workability. Now Stuart Halloway has reformulated Banfy Bray as: the more your APIs exceed orthogonality, the better you will like static typing My question is: What is the evidence that an API has exceeded its orthogonality in the context of types? Clarification Tim Bray introduces the idea of orthogonality and APIs. Where you have one API and it is mainly dealing with Strings (ie a web server serving requests and responses), then a uni-typed language (python, ruby) is 'aligned' to that API - because the the type system of these languages isn't sophisticated, but it doesn't matter since you're dealing with Strings anyway. He then moves on to Android programming, which has a whole bunch of sensor APIs, which are all 'different' to the web server API that he was working on previously. Because you're not just dealing with Strings, but with different types, the API is non-orthogonal. Tim's point is that there is a empirical relationship between your 'liking' of types and the API you're programming against. (ie a subjective point is actually objective depending on your context).

• Does upgrading RAM causes increase in Graphic card's share?

  - by A.S.

  I have asked this question on Ask Ubuntu, and I was suggested to Upgrade RAM from most voted answers. But I got a point about my graphics card. Since, I can upgrade RAM and not graphics card, Does upgrading RAM also cause graphics memory to increase. To clear the point: My specs are given below: Laptop : Lenovo 3000 Y410. (bought in 2008 October) RAM: 1 GB (DDR2) External Graphics (Dedicated): N/A Internal Graphics (Shared): 256 MB Graphics Chipset: Intel GMA X3100 My Question is: If I increase my RAM to 3 GB, will it increase graphics cards share of the Memory. In other word, If graphics card shares 256 MB in 1GB RAM, will it share more, when I upgrade the RAM into 2GB or more ? Authentic resource link will be much appreciated I have recently known that, My chipset GMA X3100 can address 384 MB of RAM. So the question.

• Intelligence as a vector quantity

  - by Senthil Kumaran

  I am reading this wonderful book called "Coders at Work: Reflections on the Craft of Programming" by Peter Seibel and I am at part wherein the conversation is with Joshua Bloch and I found this answer which is an important point for a programmer. The paragraph, goes something like this. There's this problem, which is, programming is so much of an intellectual meritocracy and often these people are the smartest people in the organization; therefore they figure they should be allowed to make all the decisions. But merely the fact they are the smartest people in the organization does not mean that they should be making all the decisions, because intelligence is not a scalar quantity; it's a vector quantity. Here at the last sentence, I fail to get the insight which is he trying to share. Can someone explain it in a little further as what he means by a vector quantity, possibly trying to present the same insight. Further down, I get the point that he is not taking about having an organization where non-technical people (sometimes clueless) can be managers of the technical people for some reason that they can spend more time to write emails well, because the very next statement following the above paragraph was. And if you lack empathy or emotional intelligence, then you shouldn't be designing APIs or GUIs or languages. I understand that he is saying that in Software engineering, programmers should know how the users will see their product and design for them. I felt the above paragraph was very interesting.

• Project collision shapes to plane for 2.5D collision detection

  - by Jkh2

  I am working on a top down 2.5D game. In the game anything that overlaps on the screen should be 'colliding' with each other regardless of whether they are on the same plane in the 3D world. This is illustrated below from a side-ways view: The orange and green circles are spheres floating in the 3D world. They are projected onto a plane parallel to the viewport plane (y = 0 in the image) and if they overlap there is a collision event between them. These spheres are attached to other meshes to represent the sphere bounding boxes for collisions. The way I plan to implement this at the moment is the following: Get the 3D world position at the center of the sphere. Use Camera.WorldToViewportPoint to project the point to the viewport plane. Move a Sphere Collider with the radius of the sphere to that point. Test for collisions using unity colliders. My question is how to extend this to work for rotated cuboids. For instance if I have two rotated cuboids, if I follow the logic above it would not work as intended as the cuboids may not collide but they could still be intersected on the view plane. An example is below: Is there a way to project a cuboid that would be aligned with the plane? Would it be a valid cuboid for all rotations if I did this?

• Alternatives to a leveling system

  - by Bane

  I'm currently designing a rough prototype of a mecha fighting game. These are the basics I came up with: Multiplayer (matchmaking for up to 10 people, for now) Browser based (HTML5) 2D (<canvas>) Persistent (as in, players have accounts and don't have to use a new mech each time they start a match) Players earn money upon destroying another mech, which is used to buy parts (guns, armor, boosters, etc) Simplicity (both of the game itself, and of the development of said game) No "leveling" (as in, players don't get awarded with XP) The last part is bothering me. At first, I wanted to have players gain experience points (XP) when destroying other mechs, but gaining two things at once (money and XP) seemed to be in conflict with my last point, which is simplicity. If I were to have a leveling system, that would require additional development. But, the biggest problem is that I simply couldn't fit it anywhere! Adding levels would require adding meaning to these levels, and most of the things that I hoped to achieve could already be achieved with the money mechanic I introduced. So I decided to drop leveling off completely. That, in turn, removed a fairly popular and robust mean of progression in games from my game (not that I would use it well anyway). Is there another way of progression in games, aside from leveling and XP points, that wouldn't get rendered redundant by my money mechanic, would be somehow meaningful (even on a symbolic level), and wouldn't be in conflict with my last point, which is simplicity?

• When is meta description still relevant?

  - by Jeff Atwood

  I received this bit of advice about the meta description tag recently: Meta descriptions are used by Google probably 80% of the time for the snippet. They don’t help with rankings but you should probably use them. You could just auto generate them from the first part of the question. The description tag exists in the header, like so: <meta name="Description" content="A brief summary of the content on the page."> I'm not sure why we would need this field, as Google seems perfectly capable of showing the relevant search terms in context in the search result pages, like so (I searched for c# list performance): In other words, where would a meta description summary improve these results? We want the page to show context around the actual search hits, not a random summary we inserted! Google Webmaster Central has this advice: For some sites, like news media sources, generating an accurate and unique description for each page is easy: since each article is hand-written, it takes minimal effort to also add a one-sentence description. For larger database-driven sites, like product aggregators, hand-written descriptions are more difficult. In the latter case, though, programmatic generation of the descriptions can be appropriate and is encouraged -- just make sure that your descriptions are not "spammy." Good descriptions are human-readable and diverse, as we talked about in the first point above. The page-specific data we mentioned in the second point is a good candidate for programmatic generation. I'm struggling to think of any scenario when I would want the Google-generated summary, that is, actual context from the page for the search terms, to be replaced by a hard-coded meta description summary of the question itself.

• Can someone explain the "use-cases" for the default munin graphs?

  - by exhuma

  When installing munin, it activates a default set of plugins (at least on ubuntu). Alternatively, you can simply run munin-node-configure to figure out which plugins are supported on your system. Most of these plugins plot straight-forward data. My question is not to explain the nature of the data (well... maybe for some) but what is it that you look for in these graphs? It is easy to install munin and see fancy graphs. But having the graphs and not being able to "read" them renders them totally useless. I am going to list standard plugins which are enabled by default on my system. So it's going to be a long list. For completeness, I am also going to list plugins which I think to understand and give a short explanation as to what I think it's used for. Pleas correct if I am wrong with any of them. So let me split this questions in three parts: Plugins where I don't even understand the data Plugins where I understand the data but don't know what I should look out for Plugins which I think to understand Plugins where I don't even understand the data These may contain questions that are not necessarily aimed at munin alone. Not understanding the data usually mean a gap in fundamental knowledge on operating systems/hardware.... ;) Feel free to respond with a "giyf" answer. These are plugins where I can only guess what's going on... I hardly want to look at these "guessing"... Disk IOs per device (IOs/second)What's an IO. I know it stands for input/output. But that's as far as it goes. Disk latency per device (Average IO wait)Not a clue what an "IO wait" is... IO Service TimeThis one is a huge mess, and it's near impossible to see something in the graph at all. Plugins where I understand the data but don't know what I should look out for IOStat (blocks/second read/written)I assume, the thing to look out for in here are spikes? Which would mean that the device is in heavy use? Available entropy (bytes)I assume that this is important for random number generation? Why would I graph this? So far the value has always been near constant. VMStat (running/I/O sleep processes)What's the difference between this one and the "processes" graph? Both show running/sleeping processes, whereas the "Processes" graph seems to have more details. Disk throughput per device (bytes/second read/written) What's thedifference between this one and the "IOStat" graph? inode table usageWhat should I look for in this graph? Plugins which I think to understand I'll be guessing some things here... correct me if I am wrong. Disk usage in percent (percent)How much disk space is used/remaining. As this is approaching 100%, you should consider cleaning up or extend the partition. This is extremely important for the root partition. Firewall Throughput (packets/second)The number of packets passing through the firewall. If this is spiking for a longer period of time, it could be a sign of a DOS attack (or we are simply recieving a large file). It can also give you an idea about your firewall performance. If it's levelling out and you need more "power" you should consider load balancing. If it's levelling out and see a correlation with your CPU load, it could also mean that your hardware is not fast enough. Correlations with disk usage could point to excessive LOG targets in you FW config. eth0 errors (packets in/out)Network errors. If this value is increasing, it could be a sign of faulty hardware. eth0 traffic (bits/second in/out)Raw network traffic. This should correlate with Firewall throughput. number of threadsAn ever-increasing value might point to a process not properly closing threads. Investigate! processesBreakdown of active processes (including sleeping). A quick spike in here might point to a fork-bomb. A slowly, but ever-increasing value might point to an application spawning sub-processes but not properly closing them. Investigate using ps faux. process priorityThis shows the distribution of process priorities. Having only high-priority processes is not of much use. Consider de-prioritizing some. cpu usageFairly straight-forward. If this is spiking, you may have an attack going on, or a process is hogging the CPU. Idf it's slowly increasing and approaching max in normal operations, you should consider upgrading your hardware (or load-balancing). file table usageNumber of actively open files. If this is reaching max, you may have a process opening, but not properly releasing files. load averageShows an summarized value for the system load. Should correlate with CPU usage. Increasing values can come from a number of sources. Look for correlations with other graphs. memory usageA graphical representation of you memory. As long as you have a lot of unused+cache+buffers you are fine. swap in/outShows the activity on your swap partition. This should always be 0. If you see activity on this, you should add more memory to your machine!

• Aligning text to the bottom of a div: am I confused about CSS or about blueprint? [closed]

  - by larsks

  I've used Blueprint to prototype a very simple page layout...but after reading up on absolute vs. relative positioning and a number of online tutorials regarding vertical positioning, I'm not able to get things working the way I think they should. Here's my html: <div class="container" id="header> <div class="span-4" id="logo"> <img src="logo.png" width="150" height="194" /> </div> <div class="span-20 last" id="title"> <h1 class="big">TITLE</h1> </div> </div> The document does include the blueprint screen.css file. I want TITLE aligned with the bottom of the logo, which in practical terms means the bottom of #header. This was my first try: #header { position: relative; } #title { font-size: 36pt; position: absolute; bottom: 0; } Not unexpectedly, in retrospect, this puts TITLE flush left with the left edge of #header...but it failed to affect the vertical positioning of the title. So I got exactly the opposite of what I was looking for. So I tried this: #title { position: relative; } #title h1 { font-size: 36pt; position: absolute; bottom: 0; } My theory was that this would allign the h1 element with the bottom of the containing div element...but instead it made TITLE disappear, completely. I guess this means that it's rendering off the visible screen somewhere. At this point I'm baffled. I'm hoping someone here can point me in the right direction. Thanks!

• converting a mouse click to a ray

  - by Will

  I have a perspective projection. When the user clicks on the screen, I want to compute the ray between the near and far planes that projects from the mouse point, so I can do some ray intersection code with my world. I am using my own matrix and vector and ray classes and they all work as expected. However, when I try and convert the ray to world coordinates my far always ends up as 0,0,0 and so my ray goes from the mouse click to the centre of the object space, rather than through it. (The x and y coordinates of near and far are identical, they differ only in the z coordinates where they are negatives of each other) GLint vp[4]; glGetIntegerv(GL_VIEWPORT,vp); matrix_t mv, p; glGetFloatv(GL_MODELVIEW_MATRIX,mv.f); glGetFloatv(GL_PROJECTION_MATRIX,p.f); const matrix_t inv = (mv*p).inverse(); const float unit_x = (2.0f*((float)(x-vp[0])/(vp[2]-vp[0])))-1.0f, unit_y = 1.0f-(2.0f*((float)(y-vp[1])/(vp[3]-vp[1]))); const vec_t near(vec_t(unit_x,unit_y,-1)*inv); const vec_t far(vec_t(unit_x,unit_y,1)*inv); ray = ray_t(near,far-near); What have I got wrong? (How do you unproject the mouse-point?)

• Demystifying "chunked level of detail"

  - by Caius Eugene

  Just recently trying to make sense of implementing a chunked level of detail system in Unity. I'm going to be generating four mesh planes, each with a height map but I guess that isn't too important at the moment. I have a lot of questions after reading up about this technique, I hope this isn't too much to ask all in one go, but I would be extremely grateful for someone to help me make sense of this technique. 1 : I can't understand at which point down the Chunked LOD pipeline that the mesh gets split into chunks. Is this during the initial mesh generation, or is there a separate algorithm which does this. 2 : I understand that a Quadtree data structure is used to store the Chunked LOD data, I think i'm missing the point a bit, but Is the quadtree storing vertex and triangles data for each subdivision level? 3a : How is the camera distance usually calculated. When reading up about quadtree's, Axis-aligned bounding box's are mentioned a lot. In this case would each chunk have a collision bounding box to detect the camera or player is nearby? or is there a better way of doing this? (raycast maybe?) 3b : Do the chunks calculate the camera distance themselves? 4 : Does each chunk have the same "resolution". for example at top level the mesh will be 32x32, will each subdivided node also be 32x32. Example below:

• Extending Database-as-a-Service to Provision Databases with Application Data

  - by Nilesh A

  Oracle Enterprise Manager 12c Database as a Service (DBaaS) empowers Self Service/SSA Users to rapidly spawn databases on demand in cloud. The configuration and structure of provisioned databases depends on respective service template selected by Self Service user while requesting for database. In EM12c, the DBaaS Self Service/SSA Administrator has the option of hosting various service templates in service catalog and based on underlying DBCA templates.Many times provisioned databases require production scale data either for UAT, testing or development purpose and managing DBCA templates with data can be unwieldy. So, we need to populate the database using post deployment script option and without any additional work for the SSA Users. The SSA Administrator can automate this task in few easy steps. For details on how to setup DBaaS Self Service Portal refer to the DBaaS CookbookIn this article, I will list steps required to enable EM 12c DBaaS to provision databases with application data in two distinct ways using: 1) Data pump 2) Transportable tablespaces (TTS). The steps listed below are just examples of how to extend EM 12c DBaaS and you can even have your own method plugged in part of post deployment script option. Using Data Pump to populate databases These are the steps to be followed to implement extending DBaaS using Data Pump methodolgy: Production DBA should run data pump export on the production database and make the dump file available to all the servers participating in the database zone [sample shown in Fig.1] -- Full exportexpdp FULL=y DUMPFILE=data_pump_dir:dpfull1%U.dmp, data_pump_dir:dpfull2%U.dmp PARALLEL=4 LOGFILE=data_pump_dir:dpexpfull.log JOB_NAME=dpexpfull Figure-1:  Full export of database using data pump Create a post deployment SQL script [sample shown in Fig. 2] and this script can either be uploaded into the software library by SSA Administrator or made available on a shared location accessible from servers where databases are likely to be provisioned Normal 0 -- Full importdeclare    h1   NUMBER;begin-- Creating the directory object where source database dump is backed up.    execute immediate 'create directory DEST_LOC as''/scratch/nagrawal/OracleHomes/oradata/INITCHNG/datafile''';-- Running import    h1 := dbms_datapump.open (operation => 'IMPORT', job_mode => 'FULL', job_name => 'DB_IMPORT10');    dbms_datapump.set_parallel(handle => h1, degree => 1);    dbms_datapump.add_file(handle => h1, filename => 'IMP_GRIDDB_FULL.LOG', directory => 'DATA_PUMP_DIR', filetype => 3);    dbms_datapump.add_file(handle => h1, filename => 'EXP_GRIDDB_FULL_%U.DMP', directory => 'DEST_LOC', filetype => 1);    dbms_datapump.start_job(handle => h1);    dbms_datapump.detach(handle => h1);end;/ Figure-2: Importing using data pump pl/sql procedures Using DBCA, create a template for the production database – include all the init.ora parameters, tablespaces, datafiles & their sizes SSA Administrator should customize “Create Database Deployment Procedure” and provide DBCA template created in the previous step. In “Additional Configuration Options” step of Customize “Create Database Deployment Procedure” flow, provide the name of the SQL script in the Custom Script section and lock the input (shown in Fig. 3). Continue saving the deployment procedure. Figure-3: Using Custom script option for calling Import SQL Now, an SSA user can login to Self Service Portal and use the flow to provision a database that will also  populate the data using the post deployment step. Using Transportable tablespaces to populate databases Copy of all user/application tablespaces will enable this method of populating databases. These are the required steps to extend DBaaS using transportable tablespaces: Production DBA needs to create a backup of tablespaces. Datafiles may need conversion [such as from Big Endian to Little Endian or vice versa] based on the platform of production and destination where DBaaS created the test database. Here is sample backup script shows how to find out if any conversion is required, describes the steps required to convert datafiles and backup tablespace. SSA Administrator should copy the database (tablespaces) backup datafiles and export dumps to the backup location accessible from the hosts participating in the database zone(s). Create a post deployment SQL script and this script can either be uploaded into the software library by SSA Administrator or made available on a shared location accessible from servers where databases are likely to be provisioned. Here is sample post deployment SQL script using transportable tablespaces. Using DBCA, create a template for the production database – all the init.ora parameters should be included. NOTE: DO NOT choose to bring tablespace data into this template as they will be created SSA Administrator should customize “Create Database Deployment Procedure” and provide DBCA template created in the previous step. In the “Additional Configuration Options” step of the flow, provide the name of the SQL script in the Custom Script section and lock the input. Continue saving the deployment procedure. Now, an SSA user can login to Self Service Portal and use the flow to provision a database that will also populate the data using the post deployment step.

• IT Audit checklist

  - by PHLiGHT

  I recently have taken on the position of a one man show for a company that is going to have an audit. The network isn't anywhere close to prepared and I have been looking for a general audit checklist since one hasn't been provided by the auditors and haven't found much good information out there. Does anyone have a nice template that will give me a good starting point. I know that this will be highly customized to the company but a starting point will be helpful to outline to management just how much work is needed. Thanks,

• Problems getting Squirrelmail and passenger working on apache

  - by Kenneth

  I'm trying to have a setup where I want to run a squirrelmail and Passenger on the same apache server, having a url point to squirrelmail and everything else handled by passenger. I've gotten so far that both squirrelmail and passenger will run fine by themselves but when passenger is running it handles all urls. So far I've tried using Alias and Redirect to point a webmail/ url to squirrelmails directory but that does not work. Here is my httpd.conf file: <VirtualHost *:80> ServerName not.my.real.server.name DocumentRoot /var/www/sinatra/public # Does not work: #Redirect webmail/ /usr/share/squirrelmail/ #<Directory /usr/share/squirrelmail> # Require all granted #</Directory> <Directory /var/www/sinatra/public> Order allow,deny Allow from all </Directory> </VirtualHost>

• How to calculate turn heading to a missile?

  - by Tony

  I have a missile that is shot from a ship at an angle, the missile then turns towards the target in an arc with a given turn radius. How do I determine the point on the arc when I need to start turning so the missile is heading straight for the target? EDIT What I need to do before I launch the missiles is calculate and draw the flight paths. So in the attached example the launch vehicle has a heading of 90 deg and the targets are behind it. Both missiles are launched at a relative heading of -45deg or + 45 deg to the launch vehicle's heading. The missiles initially turn towards the target with a known turn radius. I have to calculate the point at which the turn takes the missile to heading at which it will turn to directly attack the target. Obviously if the target is at or near 45 degrees then there is no initial turn the missile just goes straight for the target. After the missile is launched the map will also show the missile tracking on this line as indication of its flight path. What I am doing is working on a simulator which mimics operational software. So I need to draw the calculated flight path before I allow the missile to be launched. In this example the targets are behind the launch vehicle but the precalculated paths are drawn.

• How to setup heartbeat for IP fail over on SSH failure

  I wonder if anyone can help me, I am trying to setup heartbeat on a redhat 5 to failover an IP address when ssh stops responding on a server. So basically you ssh to a VIP and then get put through which ever server has the floating ip. 192.168.0.100 | | /------------------------\ | /------------------------\ | Server 01 | | | Server 02 | | eth0 - 192.168.0.1 |-----/ | eth0 - 192.168.0.2 | | eth0:0 - 192.168.0.100 | | eth0:0 - down | \------------------------/ \------------------------/ if ssh stops responding i want eth0:0 to be brought up on the second machine to allow ssh connections to carry on being served. I have tried to follow some documents I have found online so here is my current configuration: ha.cf bcast eth0 keepalive 2 warntime 10 deadtime 30 initdead 120 udpport 694 auto_failback off node vm-bal01 node vm-bal02 debugfile /var/log/ha-debug logfile /var/log/ha-log authkeys auth 1 1 sha1 sshhhsecret1234 haresources server01 192.168.0.100/24/eth0:0/192.168.0.255 Hope someone can help as this is driving me nuts...

• convert image to spritesheet of tiles for isometric map?

  - by Paul

  is there a way to convert an isometric image (like the first image) to a spritesheet (like the second image), in order to place each image on the isometric map with the code? The map looks like the first image, but some buildings are bigger than just one tile, so I need several squares (let's say the first image is a building, made of multiple tiles with different colors), and each square is placed with an offset of 64x32. The building is created in Blender and I save the image with the isometric perspective. But I have to split each square from this image in order to have the spritesheet, maybe there is smarter way, or a java software that would make the conversion for me?

• renaming hard drives (sdc to sdb) on the fly

  - by w00t

  ata2: link is slow to respond, please be patient (ready=0) kernel: [2761026.198796] ata2: soft resetting link kernel: [2761031.226669] ata2.00: disabled kernel: [2761031.226720] ata2: EH complete kernel: [2761031.226753] sd 1:0:0:0: [sdb] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK,SUGGEST_OK After receiving the error above, I couldn't access /dev/sdb anymore. Not wanting to restart the server, I rescanned for the device using echo "- - -" > /sys/class/scsi_host/host1/scan and it readded the drive as /dev/sdc. From what I have found, I need to use echo "scsi add-single-device 0 0 3 0" > /proc/scsi/scsi, "3" being the SCSI ID which corresponds to sdb. Everything nice up to the point I execute the command and get -bash: echo: write error: Invalid argument. All the solutions point to using this method, but I am unable to. Any other method available?

• Is it more valuable to double major in Computer Science/Software Engineering or get an undergraduate CS degree with a Masters in SE?

  - by Austin Hyde

  A friend and I (both in college) are currently in a debate over which is better, in terms of employment opportunities, experience, and education: a Bachelors degree in both Computer Science and Software Engineering, or a Bachelors in Computer Science with a Masters in Software Engineering. My point of view is that I would rather go to school for 4-4.5 years to learn both sides of the field, and be out working on real projects gaining real experience, by going the double major route. His point of view is that it would look better to potential employers if he had a Bachelors in CS and Masters in SE. That way, when he's finally done after 4 years of CS and 2-4 of SE (depending on where he goes), he can pretty much have his choosing of what he wants to do. We are both in agreement on the distinction between the two degrees: CS is "traditional" and about the theory of algorithms, data structures, and programming, where SE is the study of the design of software and the implementation of CS theory. So, what's your stance on this debate? Have you gone one route or another? And most importantly, why?
