Limits on Everything – The Isoblog.
Posted by jpluimers on 2018/05/01
Via [WayBack] Limits on Everything – The Isoblog.:
A posting at Brave New Geek about limits on everything, for example limits on message sizes and numbers of in-flight messages in message queues. Interesting read.
Very interesting read indeed: [WayBack] Take It to the Limit: Considerations for Building Reliable Systems – Brave New Geek
You have to set limits, which begs for a few questions:
- how to find out which limits and at what levels
- how to enforce these limits
Food for thought…
The first can be done with benchmarking, see for instance these from the same blogs above:
- [WayBack] Benchmark Responsibly – Brave New Geek
- [WayBack] Benchmarking Message Queue Latency – Brave New Geek
- [WayBack] Load, Load Testing and Benchmarking – The Isoblog.
Enforcing limits depends in your infrastructure and your communication stacks.

Home – Outpan – GTIN to product attribute mapping
Posted by jpluimers on 2018/04/26
On my research list: Home – Outpan as it is a key-value store of EAN (actually GTIN, so including GS1 UPC, EAN which means barcodes like UPC-12, EAN-8, EAN-13 and ITF-14).
- [WayBack] Global Trade Item Number – Wikipedia
- [WayBack] API Documentation – Outpan Developers
Legacy API
Get Product Information
GET https://api.outpan.com/v2/products/[GTIN]?apikey=[YOUR API KEY]
Add Product Name
POST https://api.outpan.com/v2/products/[GTIN]/name?apikey=[YOUR API KEY]Required POST parameters:
name: The name you would like to add for this product.
Add Product Attribute
POST https://api.outpan.com/v2/products/[GTIN]/attribute?apikey=[YOUR API KEY]Required POST parameters:
name: Name of the attribute you would like to add for this product.
value: Value for the attribute you would like to add for this product.
- [GTIN] is the barcode number (ISBN, EAN, UPC, …) of the product you’re looking up.
- All API calls must be done via HTTPS. Plain HTTP calls will be rejected.

When updates on a SELECT timeout with FireDAC, MSSQL 2016 and a ~8k varbinary field in the table
Posted by jpluimers on 2018/04/26
A change of FetchOptions.CursorKind from ckAutomatic to ckDynamic does the trick.
did fix this issue:
I stumbled about a problem regarding FireDAC and MSSQL 2016. The table has four fields, one being of type varbinary(max). When I omit this blob field from the SELECT, I can update any field without problems using the edit and post methods of TFDQuery. It is only when I include that blob field in the SELECT, I cannot update the other fields anymore (the blob is not changed). The post runs into a timeout. It seems that the table is somehow locked. That guess is backed by the fact that even a simple UPDATE query executed from Management Studio is also blocked until I reset my application inside the debugger.Interestingly an INSERT runs without problems.

How to embed a superscript Registered symbol in a Rave memo buffer.
Posted by jpluimers on 2018/04/24
Thomas Pfister came with a nice solution to this question:
[WayBack] Does anyone know how to embed a superscript Registered symbol in a Rave memo buffer? – Phillip Woon – Google+
Since Google has such bad indexing of G+, here is the solution:
procedure TForm4.RvSystem1Print(Sender: TObject);
const
SuperscriptOn = RPTFPrefix + RPTFSuperscript + RPTFOn + RPTFSuffix; // from RpDefine.pas
SuperscriptOff = RPTFPrefix + RPTFSuperscript + RPTFOff + RPTFSuffix;
var
MemoBuf: TMemoBuf;
begin
MemoBuf := TMemoBuf.Create;
try
MemoBuf.Text := 'Test' + SuperscriptOn + '®' + SuperscriptOff + ' Test';
MemoBuf.PrintStart := 0.5;
MemoBuf.PrintEnd := 8.0;
with Sender as TBaseReport do begin
PrintMemo(MemoBuf, 1, true);
end;
finally
FreeAndNil(MemoBuf);
end;
end;

Tip for the doc team: make TMonitor.Enter docs more clear on non-blocking re-entry from the same thread
Posted by jpluimers on 2018/04/19
Even when the Delphi team was large, the documentation was lacking, so with the reduced Delphi team size, I don’t have high expectations of the below to get fixed.
But since much of the post Delphi 7 run-time library looks a lot like the .NET core, you can usually fallback to the Microsoft documentation.
Tip for the doc team: make http://docwiki.embarcadero.com/Libraries/en/System.TMonitor.Enter more clear. Especially that if the same thread calls TMonitor.Enter more than one time, it will allow entry without blocking as per System.Threading.Monitor.Enter Method (Object) documentation https://msdn.microsoft.com/en-us/library/de0542zz
(note that this got introduced in Delphi XE3: http://docwiki.embarcadero.com/Libraries/XE3/en/System.TMonitor.Enter)
