"i.e." vs "e.g."

another one in the note-to-self series:
what abbreviation to choose when in doubt: "i.e." vs. "e.g."?
  • "i.e." -> id est -> à la "in essence"
  • "e.g." -> exempli gratia -> à la "example given"
I'm a classical dichotomy, i.e. dive instructor, IT architect and wanna-be chef, all in one person.
You say: drink? I say: yes, potatoes, e.g. tequila.

macbook pro: HDD -> SDD

just replaced the internal 320GB HDD of my mid-2010 macbook pro (13'') ...
 ...with a 256GB SDD from Samsung:

maceinsteiger.de's article (sorry, German only) provided a good guide on how to do this.

Two caveats though:
  1. you'll need a size 16 tork screwdriver. Otherwise you won't get the attachment screws of the HDD frame.
  2. after booting from DVD, the system didn't recognize the SDD as a volume to install OS X on.
    Don't freak out: it's because the drive simply isn't formatted and partitioned yet.
    There's access to the Hard-Drive-Utility (funny...) from the install screen top menu. So just start, format, and -voilà- you'll see SDD as a possible install target.
hth again. someone. somehow.

FYI: RAM in mid-2010 macbook pro

just a quick FYI because I searched for it without any relevant result on the internetz:

the original RAM in my mid-2010 macbook pro (13'', MacBookPro7,1) was manufactured by hynix.
part no is HMT125S6TFR8C.
it is labeled with
2GB 2Rx8 PC3 - 8500S - 7 - 10 - F2
(part no) - G7 N0 AA - C

I replaced it with 2 x 4GB from Kingston, and now OS X shows "0x0198" as the manufacturer in "about this mac".

hth. somehow. someone.

SAP Passport on OS X / iOS


note to self: since it's nowhere to be found how to operate the SAP marketplace, support portal or SDN with a certificate in Safari (OS X) or an iOS device:
when receiving another of them SAP S-User, do the following to make the SAP passport (aka public & private key) work on OS X (Safari and the like) and iOS:

  • use Firefox (here: 8.0.1), open the Support Portal and log in a subsequent fazillion times with your S-User-Id and password
  • (sorry, German coming up) mein Profil ➔ Single-Sign-On Zertifikate verwalten
  • put your password in the fazillionst time and generate your passport 
  • Firefox will install your new SAP passport (aka public & private key) in the background and notify you upon completion (ignore the notifications about invalid Certificate Authorities and bla; it's all a big useless bloat of shady issuer-companies anyway)
Now in Firefox Advanced preferences, (you guessed it, German again) Zertifikate anzeigen. Locate your S-User-Id in (yep, German) Ihre Zertifikate, highlight and backup.

This will export your SAP passport (aka public & private key) in PKCS12-format - not so easy to do with any other browser, including the MS cripples. Because usually your private key remains hidden in binary wonderland somewhere in the proprietary niche of the browser. But you'll need both public and private key for use with the OS X / iOS keychain.

Launch the latter and import your newly exported .p12 file. 

Now happily browse the SAP marketplace, support portal or SDN via SSO with your browser certificate in Safari or your favorite iOS device.

timeline-validity Awesomeness in SLcM

One of the very first steps when both using and/or customizing SAP SLcM (Student Lifecycle Management) is to work the Academic Structure (de: Akademische Struktur). It represents the structural organization (de: Aufbauorganisation) of the entire SAP System. In SLcM, it is used to map the study programs and formal curriculums into their digital representations (de: Abbildung von Prüfungordnungen). And typically looks like this:

Academic Structure (de: Akademische Struktur)


The above shows some Bachelor Thesis that also includes a Seminar ("VS Bachelorarbeit Betriebswirtschaft", SAP object type D). Now let's say the work load/teaching activity credits for that seminar change, beginning with the upcoming Fall term (de: neue Prüfungsordnungsversion) - a common scenario in all Higher Education institutions.

In most software systems, you'd be required to create a new object of some kind that is then used from the upcoming Fall term on.

In SLcM, you can just be awesome: create an additional work load/teaching activity (SAP-terminology: additional infotype), dated with the valid time period. The previous adjust itself automatically. And this typically looks like this (relevant date here: Oct 1st, 2011):
timeline-validity awesomness

Now, whenever you work with any activity related to that seminar prior to 01.10.2011, the system calculates with 9 units. From there on, it uses the 10 units that are valid from October first.

No fuzz, no hassle, nice data model, that simple.

Oh, and did I mention that this works with any kind of objects in SLcM?
Organizational Units, Study Programs, Exams, Modules, Export- and Import-Associations (de: Verknüpfungen), ... etc ?
So you can pretty easily map all past, present and future changes in study programs (de: Prüfungsordnungs-Änderungen) at any time?
Without jeopardizing exam results, score bookings, calculations or reports (de: Auswertungen)? All audit-proof (de: revisionssicher)?
I didn't mention all this? Really?
Well, now you know ;)
