MBP Retina 8GB vs 16GB for data analysis - R, Python large files?

I increasingly find myself working with graph data (Neo4J, Gephi) and document databases (Mongo, CouchDB) as well as using R for clustering and analysis and Python to munge fairly large files of 1GB or larger.
8GB would probably serve me well and coming from a machine with 4GB will feel like plenty, but I suspect that I am the kind of use who would get his money worth out of 16GB.
In addition to this I will be running a Windows VM for Office Excel/VBA work and to stats packages for university very frequently.
Is getting the upgraded model worth it? Or will I not notice any difference.
Thanks,
David

I would say you will want the 16GB for a few reasons. You are working with memory-intensive datasets, and also you are running a virtual machine. VMs tend to use up a lot of RAM since it means you are running two complete OSs at the same time, on top of any other apps you might be running.
The third reason is that the Retina models cannot be upgraded after purchase. You would not want to have an 8GB forever if you discovered that your future work needed a bit more memory. You've already demonstrated doing some tasks that can be RAM-intensive, just max out the RAM and never worry about it again.
If you still have doubts, learn how to analyze RAM usage and particularly swap file behavior in Activity Monitor. If your Mac is already paging to swap files frequently, you already need the RAM. If you do work for several days and swap paging activity is low, you don't need the RAM.

Should I buy the MBP retina now or wait for the new one?

Hey
I wanna buy a new MBP retina 15" before my uni starts in fall so after like a month and a half. I already have a 2011 MBP but wanna get a new and better one so I am just wondering what is the latest 15" retina by Apple? and when is the approximate date for the release of new retinas? like I mean if Apple has a date for new releases like it has for iPhone and iPad usually like to know if it worth waiting or not
Thanks

I haven't heard anything as far as a new retina models. I just upgraded from a 13" mid 2012 non-retina pro to a 13" late 2013 retina pro. Either way I don't think there will be any major improvements to their retina pros if they do release a new one in the fall. I would say go ahead and get your retina now. Also Apple has a reuse and recycle program along with a student discount. You can take your old mac in and possibly get a store credit towards a new one but I doubt you'll get a huge discount. For my last MacBook, I would only have gotten about $350. But make sure you get what you need in it when you buy it because you can't upgrade the parts.

Flash won't install after downloading...early 2013 MBP/Retina, 8GB DDR3 1600 MHz Ram, 3GHz Intel Core i7 Processor (clean installation)

Flash Player won’t install after downloading
On the first attempt to install v14, Flash Player v13 was installed and working fine.
I opened the installation package for the new Flash Player, followed standard protocol for installing Mac software and it hung before retrieving anything.
Subsequently, while watching the beach ball spin, I got an error message that the installer could not retrieve the v13 Flash Player software.
So I uninstalled Flash Player 13 and again attempted to install v14, only to see the spinning beach ball followed by a message that the installer could not retrieve the v14 Flash Player software.
I am running OS X v10.9.4 on an early 2013 MBP/Retina display with 3GHz Intel Core i7 processor and 8GB DDR3 1600 MHz Ram.
If you have any ideas or suggestions regarding my issue, please let me know.
Sincerely.
JWH

Try un-installing and then re-installing via the web site.

The amount of memory used for data is a lot larger than the saved file size why is this and can I get the memory usage down without splitting up the file?

I end up having to take a lot of high sample rate data for relativily long periods of time. When I save the data it is usually over 100 MB. When I load the data for post-processing though the amount of memory used is excessively higher than the file size. This causes my computer to crash because 1.5 GB is not enough. Is there a way to stop this from happening withoput splitting up the file into smaller files.

LabVIEW can efficiently handle large files, far beyond 100Mb, provided that care is taken in the coding of the loading/processing routines. Here are several suggestions:
1) Check out the resources National Instruments has put together (NI Developer Zone > Development Library > Measurement and Automation Software > LabVIEW > Development System > Optimizing Applications > Managing Memory), specifically the article entitled "Managing Large Data Sets in LabVIEW".
2) Load and process the data in chunks if possible.
3) Avoid sending the data to front panel indicators, using local/global variables for data storage, or changing data types unless absolutely necessary.
4) If using LabVIEW 7.1, use the "show buffer" tool to determine when LabVIEW is creating extra
copies of data in memory.

Access HttpContent data while downloading a large file

Hello,
for downloading large files methods such as ReadAsByteArrayAsync and ReadAsStreamAsync are inefficient because everything is being cached in memory and you can't access either the byte array or the stream until the await call returns (at this point the entire
file has been downloaded).
HttpClient client = new HttpClient();
Task<HttpResponseMessage> responseTask = client.GetAsync(new Uri("http://video.ch9.ms/ch9/f04f/87cd2a8d-cf52-4b80-bd97-b089e6b2f04f/308MicrosoftAnalyticsPlatformSystemM02_high.mp4"));
HttpResponseMessage response = await responseTask;
Task<byte[]> contentTask = response.Content.ReadAsByteArrayAsync();
byte[] content = await contentTask; // when this call returns the entire file has been downloaded and file data is finally accessible
Is there a more efficient method to download large files and also to be able to access file data while the download is still running?
Thx
Steve

and if you realllly wanna do it. i think you have to do something like this; but you will have to use a stream
HttpClientHandler handler = new HttpClientHandler();
HttpClient client = new HttpClient(handler);
var response = await client.GetAsync("http://video.ch9.ms/ch9/f04f/87cd2a8d-cf52-4b80-bd97-b089e6b2f04f/308MicrosoftAnalyticsPlatformSystemM02_high.mp4", HttpCompletionOption.ResponseHeadersRead);
var responseStream = await response.Content.ReadAsStreamAsync();
byte[] buf = new byte[512];
int bufSize;
while((bufSize = (await responseStream.ReadAsync(buf, 0, buf.Length))) > 0)

Is there a way to change settings for "date modified" to reflect true file changes instead of changing upon viewing files? This is not just a Word issue.

My team and I open and view files all the time without editing them but the date modified changes anyway. This gets especially troublesome when we are working on files on each others desktops remotely. Is there any way to change these settings to reflect only changes instead of views, moves, and the like? I've read similar posts that have all reference Microsoft products but that is not the case. Our systems here operate in this way regardless of application/file type.

This discussion is going on in another thread where there has been more responses, one fix and a work-around noted. Please go here to read them: https://discussions.apple.com/message/18157324?ac_cid=142432#18157324

Data Access Error importing Large Files, which previously worked

Hi All,
I am trying to import files directly from the server (from inbox), these files worked earlier so I know there is nothing wrong with them. If I take 600 rows out of the file, and upload them, it imports fine, however if I attempt to import the entire file, which is 16 meg, I get the error "Data Access Error". Why could this be?
1. It had been working for days prior, but cant anymore.
2. A sample of the file works - pulling from the same file path.
3. I try other files (other months) that are comparable in size, 15 meg+, and none of them work. So it is indeed a file size issue.
what can I do to resolve it?
Thanks

Hello,
A "Data Access Error" means that something happened at the database level; not at the FDM level. I would suggest you clear your error log, reproduce the error log and then look at the very first entry.
Also, I would suggest you possibly open an SR for further review.
Thank you,

Two work-arounds for Siena when working with large files

MonaTech pointed out that Project Siena will crash when switching to the desktop or another app. I've also noticed this happening even when the monitor goes to sleep with inactivity. To be clear, this is *developing* in Siena, not after the app
you're working on has been compiled and installed.
The 'non-technical' work-around that has been successful for me is to split the screen before I switch to another app. It's not perfect but at least I can switch to another app (browser, desktop app, etc.) without losing where I'm at.
A more technical work-around is proposed in this thread:http://social.technet.microsoft.com/Forums/en-US/c768be8f-3c85-444e-bb44-6f29abdecee7/project-siena-app-memory-issues-with-large-project-?forum=projectsiena
If you have a version of Visual Studio (that's not Express) it may do the trick for you.
FYI - In the post you'll see that Olivier responded and indicates that this is a known issue.

Encoding for FLV results in 10x larger file CS5 vs CS4

I've recently upgraded to CS5 and the Media Encoder creates incredibly HUGE files compared to the CS4 media encoder.
For example, I can convert a 15MB mpg file to a 12 MB flv file in CS4 using the preset "FLV same as source"
I do not find a matching preset in CS5, but tried "FLV - match source atributes (medium quality)" Encoding the same file in CS5 with this preset results in 170MB file.
I've tried adjusting the settings, comparing the options in both versions, and I still can't get a reasonably sized file out of the CS5 media encoder.
This seems really broken to me. A 170 MB file is not useful in any way. Do I have bad presets?
Adobe Media Encoder version is 5.0.1.0 (32-bit)
thanks for any suggestions.
rp.

I am having the exact same issue with one exeption, I'm trying to convert a 10sec long mpg into a FLV. LIke you in CS4 it took just seconds to convert and the final FLV was about 1mb, if that. Now the same 10sec mpg in CS5, even after trimming as much as I can from settings, i'm still looking at 900mb, it starts at over 3000mb. I'm doing the same thing in 5 that I was in 4, web 640x480, and disabling the audio(which helps by a few hundred mb). The absolute best I can get is 70mb, and the conversion process still takes about 2.5 hrs to complete. If you hear back on this please pass it along to me, if I don't notice.

8gb ram or 16gb for my CIS courses

I recently got used Mid 2012 13’ Non-Retina MacBook Pro in pristine condition. I have already upgraded the stock HDD to a Samsung 840 EVO 250GB SSD but I am hesitant to upgrade the RAM without some advice from those who have used the same programs I will be using.
My debate is between getting 8GB or 16GB for Adobe CS6 and other programs that will be included in my CIS degree (just starting off). Obviously 16GB would be better but it is also about double the cost. Will 8GB be enough or should I just bite the bullet and spend the cash?
I know I could scour the forums and maybe find an answer related but I’d rather have the question answered first hand from those who have been in the same position as me.
OS X Yosemite Beta
MacBook Pro (Non-Retina 13-inch, Mid 2012)
2.5 GHz Intel Core i5
4 GB 1600 MHz DDR3
Samsung 840 EVO 250GB SSD

What I forgot to mention is that Macs are very selective regarding RAM. Make certain that you install RAM withe proper specifications (204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM) and the best sources of Mac compatible RAM are OWC and Crucial.

Why has the price of apple care for MBP retina increased?

A couple of weeks ago I'm so sure it was quoted as approx $250, now it is $429! I'm looking at the 2.3 gHz model and using the Australian website both times... My main concern is has the price increased because there are alot of problems with the MBP retina?

250 is for Air & 13" models
350 for 15-17" and Retina
Just where are you seeing 429. Post a link.

2.4 ghz vs 2.7ghz MBP retina

Hi,
I was wondering whether with the new MBP retina the upgrade from 2.4ghz i7 to 2.7ghz is really worth it ($100). I do use some relatively power hungry engineering programs in both linux and windows 8 virtualizations, however when i run the virtualizations i generally dont have many programs open on the mac half of the computer. I also use a couple programs like wolfram's mathematica for data analysis. I don't really do much photo and video editing aside from some minor touch ups to vacation photos.
Thanks
Vivek

For a $100, yes. It would have been nice if that upgrade also got you some more cache on the CPU, but it doesn't. But even so, 300 more MHz for $100 isn't too bad.
I always tell people that if the next component bump is within $175 to go ahead and do it (depending on what it is). Mostly always concentrate on CPU speed/cache size increase, RAM amount, and HD speed (from 5400 to 7200). In this case, you don't need to worry about the HD since it's an SSD.
I will say this. If you had to pick that CPU upgrade or doubling your RAM but can't do both, then definitely double the RAM instead of the CPU. More gain resource gain that way.

Yes I have the 2004 MS Office for Mac installed. However, I cannot confirm that the add in has been loaded when using Excel.
The procedure that I am using:
1. With MS Excel open, I go into the "Tools" tab and select "Add-ins"
2. The "Add-ins" sub-box opens and I check the desired utilities, in this case Analysis Toolbox and I hit the "Select" button.
3. Next another sub-box opens entitled, "Choose an Add-in". With the MS Office CD in I scroll oven until I locate the sub-folder "Analysis Tools" which opens up four additional options: Analysis ToolPak, Analysis ToolPak - VBA, FuncRes, and ProcDBRes. I select Analysis ToolPak and then "Open".
4. I receive a pop up message, "Copy Analysis ToolPak to the Add-ins folder?" I select "yes" .
5. Thinking that the process has been completed, I go back to the MS Excel worksheet, select "Tools" tab and Data Analysis is not there.

Data analysis and SAP supplied programs etc

1.What transactions do you use for data analysis?
2.What are the techniques involved in using SAP supplied programs?
Do we prefer to write your own programs to load master data? Why?
