| With work being the way it is I don't have as much time to devote to programming anymore but I still check around the community from time to time. |
|
|
Well, good to know that someone is still taking a peek in here every now and again 
I imagine that calc programming has come to a halt for you as well? |
|

I try to check it occasionally but i'm not really as active as I should be. A lot of that is due to a job change in 2012 but that's another story.
Biggest problem is that I had to disable registrations on this board cause it was getting hammered by spam bots (about 400-1000 an hour, although stopforumspam was blocking 99.99% of it) and was taking too much host CPU. Should really start looking for another forum to use since eblah is basically dead development wise. If it didn't work so reliably I would have got rid of it already. |
|
|
| I wonder if anyone still comes on here. Been quite some time since any activity happened. :< |

Registration is back online. A eblah modder by the name of Martin has implemented a stopforumspam mod for eblah that automatically filters using our method. It's already stopped 6 registrations so far. Already it's become my favorite mod so far, so Thanks goes to him.
I've also removed the IP ban lists, since it appears to be more effective than banning by IP, so we're going to really put it through the test. |
|
|
Due to heavy spamming the past couple of days. Registration is closed until the bots stop flagging the site.
We will allow registration once a fix is in place or the bots stop. Keep in mind that there's a good chance that we will no longer allow free email client registration on the board when we do come online. (if you currently have an Free email account registered, you're fine. Everyone left is validated so far) |

You'll probably notice that the site is loading much faster today. It's because the Webring code that had been on the bottom of this site as well as my previous site for over a decade now has been permanently removed from the footer. Why You ask? because Webring has decided to add unnecessary scripts and popups to their Webring member sites, and I have a serious problem with Useless linkbar scripts being run on my site.
So you're probably asking why I didn't just remove the linkbar since I'm the administrator of the Ti-basic Webring? Well, That the best part. Apparently since I didn't log into the Webring.org site within two months, (primarily due to lack of people registering to the Webring. Go Figure.) Webring decided to relinquish my administration of the webring. Supposedly they send an e-mail before they do this but I never got one. (and my spam filter logs every mail I got in the past 3 months, and it didn't get one either) Since I no longer control it, and since the Current owner or group (my guess a webring.org holding group) seems to be more concerned with collecting rings than administrating them, I came to the conclusion that it is not safe to continue using the service and removed all my sites as well as my account from webring.org.
Whats that mean for the Ti-Basic webring itself? It's zombified if the current settings I had on are in place. If you have a site in the ring I would highly suggest deleting the ring from your webring list just in case a spammer gets in the ring and users of your site get infected with viruses when they try to traverse the webring. If you were thinking of joining this ring. I'm sorry, but I'd suggest looking for another active Ti related webring. |

THE TIME HAS COME! (the walrus said) ... I have reviewed all comments, topics, posts, etc. all the way back until before I switched the language to a "Go-ish" layout, and I finally feel that OPIA is fully (syntactically and semantically) defined and decided (or at least, as much as it can be before it is coded) -- which I wanted to do before I did anything huge with the compiler.
My plans (when time permits between school, work, moving, and my soon to be first-child) are as follows:
(1) lay out a careful plan for the compiler pipeline/design. This has already been 90% grasped in my head alone (after having poured over compiler books and articles and mental experiments "for fun"), but I have recently re-read most of the chapters in Modern Compiler Implementation In Java (it's the BEST!), and been charting out a careful comparison of my design versus what everyone else swears by -- and it turns out that I am not deviating terribly much. Expect an analysis and layout of the plan from me in the future (I have it mostly set).
(2) Update the Language Overview as much as I see fit (I don't want to be too picky with it, but I do want to make sure that every aspect is well documented so nothing falls through the cracks).
(3) Jump into the coding. I will keep everyone updated as that progresses. The exciting thing is that I will release it in modules, so that you can see everything up to the tokenizing & preprocessing (this is it's current state, though I may rework that a bit to be SLIGHTLY more modular), parsing/tree-building, etc. Every aspect of the pipeline will be explained, as in (1).
Anyone is welcome to ask questions about anything they think is lacking or confusing, and I am still open to considering some changes/additions; but I don't foresee anything that would change the language enough to put of coding it now.
Side note: as for interpreted aspects, the default will be to precompute as much as possible without unraveling loops or recursive calls (unless the contents clearly have no runtime side-effects), and that the $ operator will be "deep"/recursive, causing a thing (and ALL of it's contents, except for references to externally defined entities) to be fully precomputed. |

I have been working on OPIA since 2009. OPIA is the successor (and complete do-over) for Antidisassemblage (which I worked on from 2004 to 2005, and a bit in 2007). This has been on ongoing topic at Cemetech and Omnimaga, so I figured that other websites deserve a topic too
OPIA is a C-like language (functions, variables, expressions, constructs, etc.) which brings all the power of polymorphism seen in OOP languages like Java/C# to the z80 -- but in simpler terms which expose function-pointers and method-pointers more directly, but cleanly (structs implement interfaces automatically just by having the correct methods -- thus new polymorphic behavior can be added to something without any changes to the base code or to its underlying structure!).
OPIA is very focused on low-level representation: Variables, arrays, structs, and functions are designed to match raw/native representations so that they can be tied DIRECTLY into any underlying system (e.g. use OS values as variables or call system routines as functions without extra overhead -- it's 1-to-1). Everything is designed to be stored/coded "as it would be" in assembly. OPIA has the capability to be for z80 what C is for larger systems.
OPIA will use Data-flow analysis and Liveness-Analysis, etc., to trace values through the code and precompute/optimize it as much as possible -- So go ahead and use a loop to initialize that array, and the compiler will convert it an embedded value. In addition, you can use the $ operator to REQUIRE this (and cause the compiler to take more liberties) and, for example, tell the compiler to interpret a function and embed the result as a value.
The compiler will be in Java (already started) as a command-line interface. However, it will also be modularized as a java API so that other tools can be made for the language which use the compiler to build/analyze code (Tokens, Abstract syntax trees, Optimization, Compilation, etc.) -- This means things like Notepad++, or new tools like a visual (rather than textual) code editor.
Rather than providing "everything you need" in one package, OPIA only provides core features and must be compiled on your computer. However, unlike those all-in-one packages (which are amazing, btw), OPIA can be expanded and integrated for anything and everything z80. I will be writing the core compiler (which is viewable at google code), but everyone else will have the chance to expand the language via includes/libraries/etc.
There's been a ton of discussion already, but if anything picks up here, I will try to post some summaries of past discussion -- the language design is being made concrete before I get too deep into making the compiler. Discussion will continue in forums, but official documentation of what the language "IS" so far can always be found at:

I have been playing a lot of Starcraft before. Though I got tired of it when a lot of warcraft expansions emerged. I really liked the pokemon expansion of it which worked rather as a cute add-on than anything serious.
I loved using the protoss but because it needed a lot of those gold thing with blue lighting, it makes way for needing more resources like the zerg family. |

| My favorite would have to be Detective Conan. For those who are not familiar with it, he really was a grown up investigator who solves a lot of crimes in his area. But there was one opponent he was up against which targeted him and wanted to take him away from the business. What they did was to give him a potion that made him grow small with kid traits and characteristics. Though he still continue his detective work with Mori, who he puts to sleep every time he discovers the real culprit. |

Me! I am into making music though it is only related to auto tune music I create on my mixer app on the iPad.
I first got interested into making mix tapes joining a lot of pieces from different tracks. Then I transitioned into recording real band sounds and then layer each of them so that it would produce a pretty good sound.
I am next looking into creating good beats. |

I have been looking at some rc planes as well though I have not mustered enough confidence yet to try flying rc planes myself. I have tried a lot of simulators with settings emulating weather conditions in my area. I have actually bought a mini rc helicopter but flying techniques are different for the two.
I would like to know though if there are users out there into racing remote controlled cars. I am pretty interested with that more as compared to planes. |

Thank you SO much! I don't have the calc with me at the moment, but that all sounds right.
I'll confirm it as soonn as I actually get my calculator, thanks again! |

well I don't have an Nspire, but some of the 89 calls may work.
For division, on the 89, I used to always add .0 to the question. this usually would give you a decimal answer without having to turn off pretty print. so 5/4+.0 would give you 1.25 instead of 5/4
fractions on the 89 you would separate using parenthesis so on the calc you would type (1/4)+(1/4) and it would return 1/2 as the answer.
On the 89, to solve equasions, you would use the solve( function, and it used to work like solve(x+5=7,x) and it would return 2. if that don't work try nsolve.
the solve would solve the fractional proportion as well.
Just keep in mind that these are all 89 calls. My guess is that they would work on the nspire but there's a lot of functions the 89 did that the nspire does differently or not at all. at least it's worth a shot. |

I'm taking an online "Elementary Algebra" class from my local community college. It's been a few years since I graduated high school and I've forgotten pretty much everything; including my T-84 Silver, which I never took full advantage of its potential anyway.
So I went out and got myself a new calculator, and for some reason I got the nicest one available; the TI-nspire CX CAS and I am utterly lost. Please excuse my ignorance, I'm about to ask some extremely stupid questions:
First of all, how you divide?!?! When I try, it gives me the answer as a reduced, improper fraction. How can I convert that to a decimal? Or is there a setting I can change to do it automatically.
Similarly, how do I add/subtract/multiply/divide fractions on it? To make the line between the numerator and the denominator is it just the ÷ key?
Also, I see that there is an "=" button that doesn't actually solve math problems, like the Enter button does. This leads me to believe I can enter entire equations and have the calculator solve for x. Is this true? And if so, how do I accomplish that?
Finally, will it/how do I get it to do fractional proportions? For example, what buttons would I press to solve this:
x = _ 5
9 4
I apologize for the many stupid questions, thanks in advanced for the help!

I've decided to ramp up spam detection on the board.
First off, New users have to go through another captcha, which uses pictures of cats and dogs for identification. It should cut down on automatic bot registrations, but I'm not sure if that's the case going on here.
Second, Initial posts now get screened through a spam filter, which will deny posts if it's deemed to be spam. It doesn't help with banning, but it's better than seeing console junk spam all day. Although I've noticed that they post junk questions in the game forum in order to build a post count before posting. It won't help them here since it's set so high. |

Over the past couple of weeks I've been catching spam here and there on the forum. Luckily, it's been at a manageable state so it's been easy to handle, but it is annoying to say the least. especially since it fills the userlist with a ton of members that never post. (or can't due to the IP bans in place). So some cleanup has been done to the board.
As of Today, anyone that had a post count of 0 has been deleted. If you ever posted on this board you should have no problem but if you registered and never posted, most likely you'll have to create a new account. I also have other options to handle spam volume, but as of today I don't really see a need to start using them. That will probably change over time however.
As for the spam, I'm just handling them as I see them. If I deem the post or user to be spam by content and an IP or email listing at http://www.stopforumspam.com/ , I delete the post, delete the account and ban the IP range. The spam I'm seeing tends to ask a question and then either posts a sig or has spam links involving console accessories in the body of the question. I would suggest not doing that if you want you're account to be active here. |

| My job has been really taking a ton of time this past 6 months so I haven't worked on it for awhile, but I've been thinking about where I need to move next on it. Unfortunately It's probably going to take vacation time for me to get the time to work on it. |

Haven't posted here in awhile.
Looking at my Dev logs, I noticed that for some reason I tend to work on the Landel Engine more during Christmas than any other time of the year, so this year I decided to take a week off work and spend more time on finishing up the inventory part of the engine.
The July cabin trip this year wasn't as productive as I wanted it to be Between forgetting my Development Journal, Severe Thunderstorms threatening the area (and you have to watch out for those since the cabin has no serious protection against heavy winds) and not to mention the lack of sleep from said storms during the night (damn astraphobia). Not to mention Hryu's sunburn. we at least got some of the variables sorted out. this should speed up the inventory fleshing out immensely. |

| moved this to the rants forum. figured that its a good place to archive the article without leaving it on the main portal. |

|
| moved the thread since it hasn't came back since that test, and besides, the rant forum hasn't seen much use. |

Personally, I'd go with the Ti-89 titanium. or if you can find one, a Voyage 200 (which uses the same OS but has a larger screen and qwerty keyboard, but keep in mind that most standardized tests don't let you use this calc). it's got a solid base of CE users and has a lot of programs to supplement it.
Don't know much about HP but just about any HP you can't go wrong with CE wise. They do have a much steeper learning curve vs the other brands, but they are good once you learn them. It would be my second choice if you can't get an Ti calc (or if the only Ti you can get is an nspire).
In the Casio line, the classpad is probably the best, although I'll admit I don't know much about them either. the Prizm is too new to know anything about it, but other than the screen it doesn't look much different than their fx9860 offering.
Nspire (either version) is crap. Or at least it is right now unless Ti does something to radically change that, and by that I mean, make it at least feature complete with the 89. Its a perfect example of high powered hardware hindered by crap software. If it at least had hardware supported Ti-89 emulation it would have been useful, but since Ti refuses to let the 20 year old Ti-82/83/84 OS die while killing off the Ti-85/86 OS and all but killing off the Ti-89/92/v200 OS, it only emulates the Ti-84. badly. As for third party dev, I wouldn't rely on it especially since its hacked in and TI is doing everything they can to stop it. Again that may change but you'll probably be out of college by then.
Basically, my calc rating from highest to lowest is this:
Ti-92/Voyage 200
Ti-89/Titanium
Ti-85/86 (discontinued)
Ti-82/83/84 Series
Ti-80 (discontinued)
Ti-81 (discontinued)
HP 48/49/50 series
Casio Classpad 300
Casio Prizm
Any Other Casio I'm missing
Ti-Nspire/CAS.
Also keep in mind that the above is Ti biased, since that it what I know, but at Least I hope that helps you out. |

Graphing Calculator for Computer Engineering
Hi, what Graphing Calculator would be good for Computer Engineering? In reality is more of a mix of Computer Science and Computer Engineering, for example the program includes lots of algorithms and artificial intelligence.
The choices are:
-TI-Nspire CAS
The best display and hardware. Lacks 3D Graphing, Graphing Differential Equations, Engineering Apps (like ME*Pro) and Symbolic Math Guide (SMG) and TI-Nspire’s programming capabilities are not as robust as the TI-89… yet. But all of these will probably be solved since Nspire Models are now opened to Third-Party Development, or even by an update of the OS by TI.
Also is it true that the TI-Nspire CAS doesn't give exact values (square roots are always returned as decimals rather than simplified)?
-TI-89 Titanium
The TI-89 Titanium have what the TI-Nspire CAS lacks.
-Casio PRIZM fx-CG10 (Release in January)
Would the PRIZM fx-CG10 have most of the functions of the ClassPad 330? Should I wait for this one? Anyone have some information about this one.
-Casio ClassPad330
Comes with a stylus. The ClassPad 330 comes with all the functions of the ClassPad 300 including an impressive collection of applications that support self-study, like 3D Graphing, Geometry, eActivity for creating discovery based lessons and lots more. Additional features of the ClassPad 330 include upgraded CAS Technology and Geometry Application, new AP Statistics functionality, and three new applications: Differential Equation Graph, Financial and Probability.
-HP 50g Graphing Calculator
The ability to expand memory in the SD card slot, 3D Graphing, Laplace transforms which are the basis for solving many engineering problems, Fourier transforms, and special functions such as the one required for determining a factorial value for non-integers. Also programming in RPL.
So I would like to hear suggestions, difference between them, what things one have that the others don’t, etc. Also if you could provide good online stores, to purchase any of these calculators at good prices, since I’m from Venezuela and the access to foreign currency is limited here, so every penny is worth a lot. Maybe even physical retailers as long as they’re something like BestBuy, Walmart, etc because a cousin of mine is bringing the calculator from the US. |

See that Ad Cloud thing below that says, "Come see the New Webring!"? it's not ours.
They're calling it a test. I think they're testing how many sites that are singed up to webring will chuck their ad infected code. I know I plan on it if this stuff continues or becomes a regular thing, especially if it's used for advertising. One of the reasons I don't do ads on the site (other than I don't need to and hate ads) is that many ad providers get hit by malware pushers. If they start pushing ads through webring, than I'm done with it.
Update: looks like it gone for now... |
|
|
| bummer, would have offered you guys hosting space on my site, I have tons of room, unlimited bandwidth, etc. Good to see you guys are still going though! |
