Re: [Pharo-users] Thinking aloud about project at hand

[Hilaire]

Hi,

No doubt Pharo will fit the task. I developed a financial application 
for mortgages debt consolidation where the sources of data were numerous.


With Pharo you will build a model with classes representing each part of 
the domain of your data set. With Tests you will consolidate your model, 
important when you change your model it will ensure your computations 
are still valid. I use it a lot in mortgage, debt ratio and debt 
consolidation calculus.


From your description, it seems your application will be mono-user. If 
so any text file to keep the data will be ok: xml, json, csv. But sqlite 
could be a very nice option too, I think this is what I will use.


I think you will enjoy using Pharo to write your app.

Re: [Pharo-users] Moving/rolling average implementations ?

Superb, thank you Richard, very interesting answer :)

For the rounding issue, since I got bitten once, I most of the time use 
ScaleDecimal instead of floats for data anyway.

Cheers,

Re: [Pharo-users] Thinking aloud about project at hand

Hi Tomaz,

>From the comments about the requirements you do I suggest:

- For data storage, my recommendation goes depending on two factors:
1)Installation complexity, 2) volume of data. These are two variables
that will be against one and the other. I will recommend to use
MongoDB + Voyage, that goes very well. It grows excellent with the
amount of data, it has really cool integration with Pharo and Voyage
is an excellent mapping tool; also it is a mature solution and it has
a lot of support for back-up schemes and solutions. Using MongoDB
complicates the installation process, so if you have the idea of a
easy installable application maybe SQLlite is a good alternative.

- I think using Spec2 + GTK + Roassal3 + Polymath is a good idea.
Check that Spec2 and Roassal3 are still under heavy development. They
are getting much better, but of course, it will take some time to
stabilize; but both of them are progressing very fast and they are
already quite stable.

- For developing DSL and interactive programming for non-programmers
users, Pharo is ideal. It presents a lot of tools to easily develop
DSL and the UI to make them work excellent. The idea of live
manipulation of objects and inspection of all the instances can be
easily added to a DSL.

Thanks for your attention!

Re: [Pharo-users] Thinking aloud about project at hand

[Tim Mackinnon]

Wasn’t there a recent financial app in Pharo that was made open source... there 
might be many ideas in it, and possibly a starting point.

It’s in the success pages of pharo: Quuve, there are posts from Mariano about 
what tech they used too

[Pharo-users] Internet connection active

[dario.trussardi65]

Ciao,

i have a Pharo 7.0.3 image run on Ubuntu system.

Sometime the internet connection go down.

In this status when i do the:

NetNameResolver addressForName:  'www.esug.org'  timeout: 1

the system is busy for 20 seconds ( for any request ).

The timeout: 1  is not considered.

Question:  how i can test if the internet connection is up before 
submit any NetNameResolver request ?

Googling in VisualBasic i found the ActiveConnection

It return true if internet connection is active.

Equivalent in Pharo - Gemstone ?

Thanks,

Dario

Re: [Pharo-users] Thinking aloud about project at hand

[John Aspinall]

Hi Tomaz - since a couple of people have mentioned SQLite I’d like to suggest 
ReStore as an easy way to use this from Pharo:

https://github.com/rko281/ReStoreForPharo 


ReStore lets you store your data in SQLite without needing to write any SQL, 
and offers an easy upgrade path to larger databases such as Postgres. 
Documentation (recently updated) is linked from the end of the Github readme.

Good luck with your application.

Re: [Pharo-users] Pharo on a chromebook?

[tbrunz]

I just verified that my 'pharo-adjust-cursor' script does work for Pharo
Launcher as well as Pharo images that are installed in a Linux Container on
Chromebooks that have 4K displays (e.g., the "Pixelbook" models).

If you download the bash script from 
https://github.com/tbrunz/pharo-support/blob/master/src/pharo-adjust-cursor.sh
to the directory that contains 'pharolauncher' and run it, it will update
the 'pharo-launcher' script inside.

Thereafter, when you run Pharo Launcher, or launch an image from Pharo
Launcher, the cursor on 4K Chromebook displays will look normal size.

[Pharo-users] Status of Marea?

[Hernán Morales Durand]

Hi everyone,

Just checking what it would take to update Marea for a production
environment in Pharo 8 or Pharo 9 or beyond. The last repo link I found is
this:

http://ss3.gemstone.com/ss/Marea.html

And I couldn't find other codebase in the Mariano's Github repo.

Any updates out there?

Cheers,

Hernán

Re: [Pharo-users] Status of Marea?

[Mariano Martinez Peck]

Hi Hernán,

If I remember correctly, that was the last repo I used. I just tried to
check in SmalltalkHub if there was a new repo but seems already down, so I
can't check.
Also, none of my Marea images work anymore for me because latest OSX
dropped 32 bits support. But I can look for the images and send it to you
if you want.

To bring it to latest Pharo I would think:

1) Update it to use latest Fuel version
2) Slots may have broken class proxies
3) Update Marea proxies to use the latest version of Ghost proxies
(wherever that is)

As a side note, Marea would work much better these days because of the lazy
become (AFAIK that is already in Cog since some time).

Let me know if that helps,

Re: [Pharo-users] Status of Marea?

[Hernán Morales Durand]

Hi Mariano!

Thank you for the very fast reply!
Yes, I have highSierra and Mojave was the last 32-bit supported so I can
try the image if you send it to me.

I've been wondering if there's huge performance impact if I need to walk
every node of a giant tree (like a phylogenetic tree) for some operations
in my app.

Anyway I would love to check it out :)

Cheers,

[Pharo-users] Problem downloading images

Hello,

I am having problem downloading new images through PharoLauncher, it's very
slow and around 20% download it tells "ConnectionTimedOut: Data Receive

Is there some problem or maintenance in the servers?

Probably your ISP.  I was able to download this morning (in Los Angeles), and
just downloaded a new image now, late afternoon.  Everything running quick &
smooth...
