  • SAS(Statistical Analysis System) Career As a computer science student

    - by Renju
    Hi. I have completed MSc in Computer science this academic year. So I am fresher... While I am doing graduation and post graduation I did many projects using PHP and MySQL. Now I got opportunity to get into SAS(Statistical Analysis System) career, and I heard that SAS having better career growth than PHP developement. For the past 4 days, I was working with SAS and I feel interested in working. My questions are, Since i am a computer science student whether i will have any problem in my career growth in SAS? I am ready to learn statistics also, is there anything else I have to do? Doing certification in SAS will make any changes? Is it a bad idea to get into SAS with only CSc backgrond? So please guide me for my career...

  • Advice on learning programming languages and math.

    - by Joris Ooms
    I feel like I'm getting stuck lately when it comes to learning about programming-related things; I thought I'd ask a question here and write it all down in the hope to get some pointers/advice from people. Perhaps writing it down helps me put things in perspective for myself aswell. I study Interactive Multimedia Design. This course is based on two things: graphic design on one hand, and web development on the other hand. I have quite a decent knowledge of web-related languages (the usual HTML/JS/PHP) and I'll be getting a course on ASP.NET next year. In my free time, I have learnt how to work with CodeIgniter, aswell as some diving into Ruby (and Rails) and basic iOS programming. In my first year of college I also did a class on Java (19/20 on the end result). This grade doesn't really mean anything though; I have the basics of OOP down but Java-wise, we learnt next to nothing. Considering the time I have been programming in, for example, PHP.. I can't say I'm bad at it. I'm definitely not good or great at it, but I'm decent. My teachers tell me I have the programming thing down. They just tell me I should keep on learning. So that's what I do, and I try to take in as much as possible; however, sometimes I'm unsure where to start and I have this tendency to always doubt myself. Now, for the 'question'. I want to get into iOS programming. I know iOS programming boils down to programming in Cocoa Touch and Objective-C. I also know Obj-C is a superset of C. I have done a class on C a couple of years ago, but I failed miserably. I got stuck at pointers and never really understood them.. Until like a month ago. I suddenly 'got' it. I have been working through a book on Objective-C for a week or so now, and I understand the basics (I'm at like.. chapter 6 or so). However, I keep running into similar problems as the ones I had when I did the C class: I suck at math. No, really. I come from a Latin-Modern Languages background in high school and I had nearly no math classes back then. I wanted to study Computer Science, but I failed there because of the miserable state of my mathematics knowledge. I can't explain why I'm suddenly talking about math here though, because it isn't directly related to programming.. yet it is. For example, the examples in the book I'm reading now are about programming a fraction-calculator. All good, I can do the programming when I get the formulas down.. but it takes me a full day or more to actually get to that point. I also find it hard to come up with ideas for myself. I made one small iOS app the other day and it's just a button / label kind of thing. When I press the button, it generates a random number. That's really all I could come up with. Can you 'learn' that? It probably comes down to creativity, but evidently, I'm not too great at being creative. Are there any sites or resources out there that provide something like a basic list of things you can program when you're just starting out? Maybe I'm focusing on too many things at once. I want to keep my HTML/CSS at a decent level, while learning PHP and CodeIgniter, while diving into Ruby on Rails and learning Objective-C and the iOS SDK at the same time. I just want to be good at something, I guess. The problem is that I can't seem to be happy with my PHP stuff. I want more, something 'harder'; that's why I decided to pick up the iOS thing. Like I said, I have the basics down of a lot of different languages. I can program something simple in Java, in C, in Objective-C as of this week.. but it ends there. Mostly because I can't come up with ideas for more complex applications, and also because I just doubt myself: 'Oh, that's too complex, I can never do that'. And then it ends there. To conclude my rant, let me basically rephrase my questions into a 'tl;dr' part. A. I want to get into iOS programming and I have basic knowledge of C/Objective-C. However, I struggle to come up with ideas of my own and implement them and I also suck at math which is something that isn't directly related to, yet often needed while programming. What can I do? B. I have an interest in a lot of different programming languages and I can't stop reading/learning. However, I don't feel like I'm good in anything. Should I perhaps focus on just one language for a year or longer, or keep taking it all in at the same time and hope I'll finally get them all down? C. Are there any resources out there that provide basic ideas of things I can program? I'm thinking about 'simple' command-line applications here to help me while studying C/Obj-C away from the whole iPhone SDK. Like I said, the examples in my book are mainly math-based (fraction calculator) and it's kinda hard. :( Thanks a lot for reading my post. I didn't plan it to be this long but oh well. Thanks in advance for any answers.

  • ASP.NET web-application example for newbies

    - by A-Cube
    I want to learn ASP.NET web-application development by example. I want to learn it from an already developed web-application that is good as a tutorial for newbies. A fully functional web application that is small but powerful enough to teach newbies the development effort required for web-application development. I am looking for some application that is made using software engineering principles and not just a code written haphazardly.

  • facebook Hacker cup: studious Student problem.

    - by smartmuki
    During the qualification round, the following question was asked: You've been given a list of words to study and memorize. Being a diligent student of language and the arts, you've decided to not study them at all and instead make up pointless games based on them. One game you've come up with is to see how you can concatenate the words to generate the lexicographically lowest possible string. Input As input for playing this game you will receive a text file containing an integer N, the number of word sets you need to play your game against. This will be followed by N word sets, each starting with an integer M, the number of words in the set, followed by M words. All tokens in the input will be separated by some whitespace and, aside from N and M, will consist entirely of lowercase letters. Output Your submission should contain the lexicographically shortest strings for each corresponding word set, one per line and in order. Constraints 1 <= N <= 100 1 <= M <= 9 1 <= all word lengths <= 10 Example input 5 6 facebook hacker cup for studious students 5 k duz q rc lvraw 5 mybea zdr yubx xe dyroiy 5 jibw ji jp bw jibw 5 uiuy hopji li j dcyi Example output cupfacebookforhackerstudentsstudious duzklvrawqrc dyroiymybeaxeyubxzdr bwjibwjibwjijp dcyihopjijliuiuy The program I wrote goes as: chomp($numberElements=<STDIN>); for(my $i=0; $i < $numberElements; $i++) { my $string; chomp ($string = <STDIN>); my @array=split(/\s+/,$string); my $number=shift @array; @sorted=sort @array; $sortedStr=join("",@sorted); push(@data,$sortedStr); } foreach (@data) { print "$_\n"; } The program gives the correct output for the given test cases but still facebook shows it to be incorrect. Is there something wrong with the program??

  • Counter variable for class

    - by George
    I am having problem getting this piece of code to run. The class is Student which has a IdCounter, and it is where the problem seems to be. (at line 8) class Student: def __init__(self): # Each student get their own student ID idCounter = 0 self.gpa = 0 self.record = {} # Each time I create a new student, the idCounter increment idCounter += 1 self.name = 'Student {0}'.format(Student.idCounter) classRoster = [] # List of students for number in range(25): newStudent = Student() classRoster.append(newStudent) print(newStudent.name) I am trying to have this idCounter inside my Student class, so I can have it as part of the student's name (which is really an ID#, for example Student 12345. But I have been getting error. Traceback (most recent call last): File "/Users/yanwchan/Documents/test.py", line 13, in <module> newStudent = Student() File "/Users/yanwchan/Documents/test.py", line 8, in __init__ idCounter += 1 UnboundLocalError: local variable 'idCounter' referenced before assignment I tried to put the idCounter += 1 in before, after, all combination, but I am still getting the referenced before assignment error, can you explain to me what I am doing wrong?

  • How to make a good portfolio for IT student (who loves programming) like me?

    - by Viet
    I am currently a college student, and going to apply for an university in probably next month. Unlike art student who easily put on their works such as models, designs and so on on their portfolio; I am hitting a dead corner trying to find a "creative" way to showcase my work as a programmer. It would be normal if programmer shows his good project with source code and everything else. Well, it should be no problem with actual "good" projects, but all of my projects are crappy (can't help it because I am still student, and don't have much work experience) and I don't even know it's worth to show. Nonetheless, I have learned a lot in only 1 year since I started programming. I am now familiar with Java, PHP, Actionscript3, C#, Objective-C and on my way to learn Ruby. I plan to build a Flash portfolio using Actionscript with Ruby as backend to show what I have learnt. The problem is idea. How to show people that I learned a lot of useful thing? Otherwise I hit the dead end and LOL just show what I have on Github (but i certainly never want that...)

  • Describe the Damas-Milner type inference in a way that a CS101 student can understand

    - by user128807
    Hindley-Milner is a type system that is the basis of the type systems of many well known functional programming languages. Damas-Milner is an algorithm that infers (deduces?) types in a Hindley-Milner type system. Wikipedia gives a description of the algorithm which, as far as I can tell, amounts to a single word: "unification." Is that all there is to it? If so, that means that the interesting part is the type system itself not the type inference system. If Damas-Milner is more than unification, I would like a description of Damas-Milner that includes a simple example and, ideally, some code. Also, this algorithm is often said to do type inference. Is it really an inference system? I thought it was only deducing the types. Related questions: What is Hindley Miller? Type inference to unification problem

  • Ideas for student parallel programming project

    - by chi42
    I'm looking to do a parallel programming project in C (probably using pthreads or maybe OpenMP) for a class. It will done by a group of about four students, and should take about 4 weeks. I was thinking it would be interesting to attack some NP-complete problem with a more complex algorithm like a genetic algo with simulated annealing, but I'm not sure if it would be a big enough project. Anyone knew of any cool problems that could benefit from a parallel approach?

  • SQL syntax Newbie student

    - by sammysmall
    Describe the output of the following SQL query: select custId, name from customer where region = "New York" UNION select cust.custId, cust.name from customer cust where cust.custId IN (select cust_order.custId from customer_order cust_order, company_employee comp_emp where cust_order.salesEmpId = comp_emp.empId AND comp_emp.name = 'DANIEL'); My question is: at line from customer cust is cust referring to a column in the customer table... This is a homework question I have identified the components leading up to this line and I think that cust is a column in the customer table... I am not asking for an overall solution just a bit of encouragement if I am on the right track...

  • What to see in India as a developer and student

    - by lasseespeholt
    Hi, I'm planning a trip to India around July-August. And I want to hear Indian developers or developers traveled to India if there are something interesting to see in India (around Bombay) for developers in general. Maybe a conference etc. I have looked at http://www.conferencealerts.com/computing.htm I have studied computer science in a year now but have been a spare time and independent developer for some years now. Furthermore, I have tried finding summer courses but that is properly too late now and computer science summer courses is hard to find in India. Best regards, Lasse Espeholt

  • C -- Basic Struct questions

    - by Ryan Yu
    So I'm trying to learn C right now, and I have some basic struct questions I'd like to clear up: Basically, everything centers around this snippet of code: #include <stdio.h> #include <stdlib.h> #define MAX_NAME_LEN 127 typedef struct { char name[MAX_NAME_LEN + 1]; unsigned long sid; } Student; /* return the name of student s */ const char* getName (const Student* s) { // the parameter 's' is a pointer to a Student struct return s->name; // returns the 'name' member of a Student struct } /* set the name of student s If name is too long, cut off characters after the maximum number of characters allowed. */ void setName(Student* s, const char* name) { // 's' is a pointer to a Student struct | 'name' is a pointer to the first element of a char array (repres. a string) s->name = name; } /* return the SID of student s */ unsigned long getStudentID(const Student* s) { // 's' is a pointer to a Student struct return s->sid; } /* set the SID of student s */ void setStudentID(Student* s, unsigned long sid) { // 's' is a pointer to a Student struct | 'sid' is a 'long' representing the desired SID s->sid = sid; } I've commented up the code in an attempt to solidify my understanding of pointers; I hope they're all accurate. So anyway, I have a feeling that setName and setStudentID aren't correct, but I'm not exactly sure why. Can someone explain? Thanks!

  • ColdFusion Server crash after thousands of HTTP requests

    - by Jason Bristol
    We are running ColdFusion 8 on a windows server 2003 VPS with an API that exposes student records to a partner API through a connector. Our API returns around 50k student records serialized in XML format pretty seamlessly. My question originates when something very frightening happened today when we tested our connector to our partners API. Our entire website and web host went down. We assumed that our host was just having some issues and after 4 hours with no resolution and no response from their customer service we finally got a response from them claiming that they had an "unauthorized user" in their network. After our server was back up we were unable to connect to our website as if the web service or coldfusion itself had froze. This is really where my concern comes from as I fear we may have overloaded the web service. As I mentioned before we tried sending over 50k HTTP POST requests over to our partner's API, however everything stopped after around 1.6k Is this bad practice or is there some sort of rate limiting I can relax somewhere in server configuration? We managed to find a workaround, but it bypasses our connector which is critical to our design. This would have been a one time deal as the purpose of so many requests was to populate our partner's website with current data, after that hourly syncs will keep requests down to around 100 per hour. UPDATE Our partner API is owned and operated by Pardot. We are converting students to prospects by passing student data to their API which unfortunately only seems to accept one student at a time. For that reason we have to do all 50k requests individually. Our server has 4GB of RAM, an Intel Core 2 Duo @ 2.8GHz running Windows Server 2003 SP2. I monitored the server during a 100 student sync, a 400 student sync, and a 1.4k student sync with the following results: 100 students - 2.25GB of Memory, 30-40% CPU utilization, 0.2-0.3% network bandwidth 400 students - 2.30GB of Memory, 30-50% CPU utilization, 0.2-1.0% network bandwidth 1.4k students - 2.30GB of Memory, 30-70% CPU utilization, 0.2-1.0% network bandwidth I know this is a far cry from 50k students, but I don't want to risk taking down our CMS system again assuming that was the cause. To give you a look at our code: <cfif (#getStudents.statusCode# eq "200 OK")> <cftry> <cfloop index="StudentXML" array="#XmlSearch(responseSTUD,'/students/student')#"> <cfset StudentXML = XmlParse(StudentXML)> <cfhttp url="#PARDOT_CMS_UPSERT#" method="post" timeout="10000" > <cfhttpparam type="url" name="user_key" value="#PARDOT_CMS_USERKEY#"> <cfhttpparam type="url" name="api_key" value="#api_key#"> <cfhttpparam type="url" name="email" value="#StudentXML.student.email.XmlText#"> <cfhttpparam type="url" name="first_name" value="#StudentXML.student.first.XmlText#"> <cfhttpparam type="url" name="last_name" value="#StudentXML.student.last.XmlText#"> <cfhttpparam type="url" name="in_cms" value="#StudentXML.student.studentid.XmlText#"> <cfhttpparam type="url" name="company" value="#StudentXML.student.agencyname.XmlText#"> <cfhttpparam type="url" name="country" value="#StudentXML.student.countryname.XmlText#"> <cfhttpparam type="url" name="address_one" value="#StudentXML.student.address.XmlText#"> <cfhttpparam type="url" name="address_two" value="#StudentXML.student.address2.XmlText#"> <cfhttpparam type="url" name="city" value="#StudentXML.student.city.XmlText#"> <cfhttpparam type="url" name="state" value="#StudentXML.student.state_province.XmlText#"> <cfhttpparam type="url" name="zip" value="#StudentXML.student.postalcode.XmlText#"> <cfhttpparam type="url" name="phone" value="#StudentXML.student.phone.XmlText#"> <cfhttpparam type="url" name="fax" value="#StudentXML.student.fax.XmlText#"> <cfhttpparam type="url" name="output" value="simple"> </cfhttp> </cfloop> <cfcatch type="any"> <cfdump var="#cfcatch.Message#"> </cfcatch> </cftry> </cfif> UPDATE 2 I checked the CF logs and found a couple of these: "Error","jrpp-8","06/06/13","16:10:18","CMS-API","Java heap space The specific sequence of files included or processed is: D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm, line: 675 " java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2882) at java.io.CharArrayWriter.write(CharArrayWriter.java:105) at coldfusion.runtime.CharBuffer.replace(CharBuffer.java:37) at coldfusion.runtime.CharBuffer.replace(CharBuffer.java:50) at coldfusion.runtime.NeoBodyContent.write(NeoBodyContent.java:254) at cfapi2ecfm292155732._factor30(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm:675) at cfapi2ecfm292155732._factor31(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm:662) at cfapi2ecfm292155732._factor36(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm:659) at cfapi2ecfm292155732._factor42(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm:657) at cfapi2ecfm292155732._factor37(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm) at cfapi2ecfm292155732._factor44(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm:456) at cfapi2ecfm292155732._factor38(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm) at cfapi2ecfm292155732._factor46(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm:455) at cfapi2ecfm292155732._factor39(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm) at cfapi2ecfm292155732._factor47(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm:453) at cfapi2ecfm292155732.runPage(D:\Clients\www.xxx.com\www\dev.cms\api\v1\api.cfm:1) at coldfusion.runtime.CfJspPage.invoke(CfJspPage.java:192) at coldfusion.tagext.lang.IncludeTag.doStartTag(IncludeTag.java:366) at coldfusion.filter.CfincludeFilter.invoke(CfincludeFilter.java:65) at coldfusion.filter.ApplicationFilter.invoke(ApplicationFilter.java:279) at coldfusion.filter.RequestMonitorFilter.invoke(RequestMonitorFilter.java:48) at coldfusion.filter.MonitoringFilter.invoke(MonitoringFilter.java:40) at coldfusion.filter.PathFilter.invoke(PathFilter.java:86) at coldfusion.filter.ExceptionFilter.invoke(ExceptionFilter.java:70) at coldfusion.filter.ClientScopePersistenceFilter.invoke(ClientScopePersistenceFilter.java:28) at coldfusion.filter.BrowserFilter.invoke(BrowserFilter.java:38) at coldfusion.filter.NoCacheFilter.invoke(NoCacheFilter.java:46) at coldfusion.filter.GlobalsFilter.invoke(GlobalsFilter.java:38) at coldfusion.filter.DatasourceFilter.invoke(DatasourceFilter.java:22) at coldfusion.CfmServlet.service(CfmServlet.java:175) at coldfusion.bootstrap.BootstrapServlet.service(BootstrapServlet.java:89) at jrun.servlet.FilterChain.doFilter(FilterChain.java:86) Looks like I might have crashed the JVM in CF, is there a better way to do this? We are thinking of just exporting all records initially as a CSV file and importing it into Pardot seeing as we will never have to do a request this large again.

  • Proper Usage of Arrays and Functions [closed]

    - by Ssegawa Victor
    Can some one help me write a C code that solves the following problem. PROBLEM Consider the faculty registrar who has to process results for 1st year 1st semester students. Students offer five courses CSC 1100, CSK 1101, CSC 1104, CSC 1105 and CSC 1106. The courses have credit units 4,4,4,3 and 3 respectively. Lecturers provide course work and exam marks. For each course, course work constitutes 40% of the final mark while the exam constitutes 60% of the final mark. The role of the registrar is to Compute the final mark for each student for each course. The final mark must be a whole number Compute the grade and grade point of the students for each course they offered. According to senate regulations, grades and grade points are awarded to final marks according to the following criteria Range Grade Grade Point 90 – 100 A+ 5.0 80 – 89 A 5.0 75 – 79 B+ 4.5 70 – 74 B 4.0 65 – 69 C+ 3.5 60 – 64 C 3.0 55 – 59 D+ 2.5 50 – 54 D 2.0 45 – 49 E 1.5 40 – 44 E- 1.0 0 – 39 F 0.0 Put a comment ‘Retake’ to a student for every course where the Grade Point is less than 2.0 Compute the cumulative grade point average CGPA for each student. The senate formula for CGPA is GGPA =(?_(i=1)^(i=N)¦?CU _i×GP _i ?)/(?_(i=1)^(i=N)¦CU i) Put a comment “Progress” for any student whose GGPA is greater than 2 and “Stay Put” on a student whose CGPA is less than 2 You are required to create a c program that considers a class of 25 students and: 1.Initializes an array ‘student’ which stores student names 2.Initializes arrays for course work and exam for each course. ‘cw_csc_1100’ and ‘ex_csc_1100’ store course work and exam marks (respectively) for CSC 1100. The same approach is considered for all other courses 3.Initializes the coursework and exam marks arrays with marks between 0 and 99 4.Write appropriate functions that will generate the final marks, generate grades, generate grade points, generate cumulative grade points, generate comments for students and comments for courses per student 5.Create appropriate arrays for final marks and insert the data there using the appropriate functions 6.Without having to create any extra arrays, use the functions created to generate a report per student that looks like the one bellow. Student Name: Ngubiri Course Unit Final mark Grade Grade Point Course Comment CSC 1100 43 E- 1.0 Retake CSK 1101 50 D 2.0 CSC 1104 59 D+ 2.5 CSC 1105 70 B 4.0 CSC 1106 65 C+ 3.5 CGPA 2.47 Overall Comment Progress NB It is advisable that the indices are used to identify the owners. Eg if student[x] is John, then cs_csc_100[x] should be a mark for John since the index is the same

  • Advanced XPath query

    - by alex
    Hello, I have an XML file that looks like this: <?xml version="1.0" encoding="utf-8" ?> <PrivateSchool> <Teacher id="teacher1"> <Name> teacher1Name </Name> </Teacher> <Teacher id="teacher2"> <Name> teacher2Name </Name> </Teacher> <Student id="student1"> <Name> student1Name </Name> </Student> <Student id="student2"> <Name> student2Name </Name> </Student> <Lesson student="student1" teacher="teacher1" /> <Lesson student="student2" teacher="teacher2" /> <Lesson student="student3" teacher="teacher3" /> <Lesson student="student1" teacher="teacher2" /> <Lesson student="student3" teacher="teacher3" /> <Lesson student="student1" teacher="teacher1" /> <Lesson student="student2" teacher="teacher4" /> <Lesson student="student1" teacher="teacher1" /> </PrivateSchool> There's also a DTD associated with this XML, but I assume it's not much relevant to my question. Let's assume all needed teachers and students are well defined. What is the XPath query that returns the teachers' NAMES, that have at least one student that took more than 10 lessons with them? I was looking at many XPath sites/examples. Nothing seemed advanced enough for this kind of question... Thank you

  • Which of these studies would benefit a CS student the most? [closed]

    - by user1265125
    Which of these extra-curricular studies would benefit a CS student the most? Algorithms Advanced OS programming Image processing Computer graphics Open source development Practicing on TopCoder or Codechef Something else? I realize the decision can be influenced by a number of factors, such as personal preference, what's currently hot in the jobs market, and what is likely to be in demand more in the future, however I would like to ask more experienced programmers which one(s) of these would be most beneficial to learn alongside all the required CS academics.

  • choosing Database and Its Design for Rails

    - by Gaurav Shah
    I am having a difficulty in deciding the database & its structure. Let us say the problem is like this. For my product I have various customers( each is an educational institute) Each customer have their own sub-clients ( Institution have students) Each student record will have some basic information like "name" & "Number" . There are also additional information that a customer(institution) might want to ask sub-client(student) like "email" or "semester" I have come up with two solutions : 1. Mysql _insititution__ id-|- Description| __Student__ id-|-instituition_id-|-Name-|-Number| __student_additional_details__ student_id -|- field_name -|- Value Student_additional_details will have multiple records for each student depending upon number of questions asked from institution. 2.MongoDb _insititution___ id-|- Description| _Student__ id-|-instituition_id-|-Name-|-Number|-otherfield1 -|- otherfield2 with mongo the structure itself can be dynamic so student table seems really good in mongo . But the problem comes when I have to relate student with institution . So which one is a better design ? Or some other idea ?

  • Fiscal year, quarters, student table, and faculty table... How do I relate these?!

    - by yuudachi
    I have a student and faculty table. The primary key for student is studendID (SID) and faculty's primary key is facultyID, naturally. Student has an advisor column and a requested advisor column, which are foreign key to faculty. That's simple enough, right? However, now I have to throw in dates. I want to be able to view who their advisor was for a certain quarter (such as 2009 Winter) and who they had requested. The result will be a table like this: Year | Term | SID | Current | Requested ------------------------------------------------ 2009 | Winter | 860123456 | 1 | NULL 2009 | Winter | 860445566 | 3 | NULL 2009 | Winter | 860369147 | 5 | 1 And then if I feel like it, I could also go ahead and view a different year and a different term. I am not sure how these new table(s) will look like. Will there be a year table with three columns that are Fall, Spring and Winter? And what will the Fall, Spring, Winter table have? I am new to the art of tables, so this is baffling me... Also, I feel I should clarify how the site works so far now. Admin can approve student requests, and what happens is that the student's current advisor gets overwritten with their request. However, I think I should not do that anymore, right?

  • What programming languages should every computer science student be taught?

    - by Anto
    What languages (or classes (as in paradigms) of programming languages, plus a recommended language of that class) should every computer science student be taught in college according to you? Motivate your answers; why that language? What use will one have from it? What concepts does it teach (better than language X does)? Note/clarification: This question is about computer science with heavy focus on software engineering, not pure computer science. It is still computer science education and not software engineering education which is the focus.

  • What are some recommended video lectures for a non-CS student to prepare for the GRE CS subject test?

    - by aristos
    Well the title kinda explains all there is to explain. I'm a non-cs student and was preparing to apply PhD programs in applied mathematics. But for my senior thesis I've been reading lots of machine learning and pattern recognition literature and enjoying it a lot. I've taken lots of courses with statistics and stochastics content, which I think, would help me if I get accepted to a program with ML focus, but there are only two CS courses -introduction to programming- in my transcript and therefore I decided to take the CS subject test to increase my chances. Which courses do you think would be most essential to have a good result from CS subject test? I'm thinking of watching video lectures of them, so do you have any recommendations?

  • What kind of an IT or programming job can a college student get part time?

    - by Alex Foster
    I'm a college student with a full load of classes and i need some extra money to cover some of my expenses. I love anything and everything to do with computers. I don't know how to program but have build computers before and know how windows works. I would call myself a power user. My question is, what kind of a job can someone like me get with effort? If there are some more skills that i can pick up that would benefit in getting the foot in the door i would love to hear about them. The only limitation i have is that i can't work very late in the evening most days due to classes. But usually in the morning my time is available for work. I will appreciate all answers i receive. Thank you for your help.

  • Tips for a first year CS student looking for a summer internship to gain experience?

    - by Matt
    Hello all, I am a first year CS student and my programming experience is only what I have obtained in my computer programming I and II classes this school year. (console applications in C++) I want to find a summer job/internship that would help me build my skill set. Being that I am still such a beginner pay is not a concern, minimum wage would be nice, but as long as I am learning, I really don't care. My current resume just lists a bunch of random jobs i've had in the past (burger king, summer camps, best buy, etc.) Does anyone have any tips (places to look? things to put on resume?) that might help me?
