overlappingPairsAnySatisfy:

  overlappingPairsDo: [:x :y |

  I'll start with this question first, since it is the
easiest to discuss. The brute-force approach would be to
use #select: against the word to extract all the vowels.
But a better approach, would be to imagine what you need
and delegate it. So, we already have #select:, #reject,
#detect:, and #collect: as patterns. Imagine a new
method called #count:, and implement that. (For the
purpose of the assignment, implementing #count: is
probably overkill, unless you have many, many words to
check.)
  
  
  
  
  Now, back to the first question. You want to iterate
through the word "pairwise", where you examine each
successive pair of letters.
  So, you want to iterate from 1 through n-1 and check
whether the letter at the index is the same as the
letter at the index + 1.
  That should be enough to get you going.

Very sorry to add to your frustration.  I only just followed that link to
check which instructions you were using.
Those instructions are deprecated (can anyone edit that page? or publish an
updated one?)

Please try...
$ git clone g...@github.com:OpenSmalltalk/opensmalltalk-vm.git
$ cd opensmalltalk-vm/build.linux64x64/pharo.cog.spur/build
$ ./mvm

Note this is the tip of development. Alternatively you could find the
commit hash from the stable VM and check that out.
Then try image pharo64.zip from http://files.pharo.org/get-files/70/

HTH
cheers -ben


P.S. @esteban, could we get a tag in opensmalltalk-vm repo to mark
Pharo's stable VM build.

A branch "pharo-stable" would facilitate one more step above ```git
checkout pharo-stable```
to provide a smoother path for people wanting to compile the VM for the
first time.
This branch would fast-forward along the mainline when Pharo's next stable
VM is determined.
(I expect "squeak-stable" would also be useful to have)

A tag "pharo-stable-20180618" would provide a permanent record for someone
is using
one of those stable-VMs in production who needs to branch off that point to
apply a hot fix.

Also, when it comes to the Pharo 7 Release, identical matching tags "
pharo-release-7.0"
in both opensmalltalk/opensmalltalk-vm and pharo-project/pharo would be
useful.

Hi Sven,

Thanks for the heads up. stfx has been really useful when sharing
playgrounds in workshops and hackathons, and of course we can wait until
modernization ends.

Re: [Pharo-users] Unable to compile myself Pharo

[Ben Coman]

That sounds normal.  "No stash" is not an error.
You should see new files in directory  ".git/hooks"
which help give correct date to built VM to avoid "to old" message.

btw, make sure you match your 32/64-bitness between VM and Image.

Re: [Pharo-users] stfx.eu down

[Paul DeBruicker]

I wonder if there is a way to get all the relevant configs in an image to
point to the smalltalkhub repo instead of the mc.stfx.eu repo temporarily.


In Pharo 6.1 if a person wants to switch away from the mc.stfx.eu domain in
their ConfigurationOf* and BaselineOf* specs you can right click on a
package in Nautilus, choose "Rewrite code" then choose "Rewrite code" again
and paste each of the below into the box and save it to rewrite the
repository definition.

RBParseTreeRewriter new
replace: '''http://mc.stfx.eu/ZincHTTPComponents''' with:
'''http://smalltalkhub.com/mc/SvenVanCaekenberghe/ZincHTTPComponents/main''';
yourself 

RBParseTreeRewriter new
replace: '''http://mc.stfx.eu/Zodiac''' with:
'''http://smalltalkhub.com/mc/SvenVanCaekenberghe/Zodiac/main''';
yourself 

RBParseTreeRewriter new
replace: '''http://mc.stfx.eu/Neo''' with:
'''http://smalltalkhub.com/mc/SvenVanCaekenberghe/Neo/main''';
yourself 


to "fix" Zinc, Zodiac, and Neo respectively.

[Pharo-users] stfx.eu down

[Sven Van Caekenberghe]

Hi,

This evening I somehow broke my stfx.eu server while doing an ubuntu dist 
upgrade (an old AWS EC2 machine).

This means several websites / web services hosted by that machine are down, 
most notably mc.stfx.eu (hosting several of my packages) and ws.stfx.eu (used 
for shared smalltalk workspaces). A couple of Zinc tests will also fail.

For source code access, all my public repos exist both in an up to date form on 
GitHub (http://github.com/svenvc) as well in the original form in SmalltalkHub 
(http://smalltalkhub.com/#!/~SvenVanCaekenberghe) or SS3.

The main problem there is that the distributed ConfigurationsOf and Catalog 
entries will still point to the original. This is not a problem with git's 
BaselineOf definitions.

Although the machine will no longer boot, I managed to mount the original 
volume on another instance so I can still access the whole filesystem. This 
will make it possible to eventually recover most services. But this will take 
time as these things never happen when it is convenient. It will give me an 
opportunity to modernise the setup though, which is good.

Sorry for the inconvenience.

Sven

  I'll start with this question first, since it is the

unless you have many, many words to check.)
  
  
  
  
  Now, back to the first question. You want to iterate
through the word "pairwise", where you examine each
successive pair of letters.
  So, you want to iterate from 1 through n-1 and check
whether the letter at the index is the same as the letter at
the index + 1.
  That should be enough to get you going.

I'll start with this question first, since it is the easiest to discuss.
The brute-force approach would be to use #select: against the word to
extract all the vowels. But a better approach, would be to imagine what you
need and delegate it. So, we already have #select:, #reject, #detect:, and
#collect: as patterns. Imagine a new method called #count:, and implement
that. (For the purpose of the assignment, implementing #count: is probably
overkill, unless you have many, many words to check.)


Now, back to the first question. You want to iterate through the word
"pairwise", where you examine each successive pair of letters.
So, you want to iterate from 1 through n-1 and check whether the letter at
the index is the same as the letter at the index + 1.
That should be enough to get you going.

I recloned and did it, and it doesn’t seem it did something, as it
pretty quickly ended with only that output:

galex-713@portable:~/doc/comp/src/pharo/opensmalltalk-vm$ LC_ALL=C 
scripts/updateSCCSVersions
No stash found.

[Pharo-users] any ihint how to do this

[Roelof Wobben]

  
  
Hello, 
  
  is there a way I can check if a word has 2 the same chars after
  each other

  

  I was hoping that '#groupby could help me but that one
sorts

  


  

  so abba
the aa is found 

  

or do I have to use a stream for that

could I then also use that stream to check if a word contains 3
vowels ?

I ask also on the discord app but no answer for a long time
