This weekend I was planning for my next batch of Odinzale, and I decided that I would check the iPhone app store again for a good brewing application. As luck would have it I found two.
The first application I found is called Brew Pal (iTunes). This application has a ton of features, most importantly is the ability to create recipes. It allows you to enter all your grains, hops, yeast, and other adjuncts and then it automatically calculates gravities, color, bitterness, and more. Each item type is on a sepperate screen, and it does not allow you to add your own ingredients. While the list is fairly comprehensive, I couldn’t add Honey in a way that impact the original gravity.
Brew Pal also has many useful brewing tools, such as carbonation table, flavor estimator, color estimator, hydrometer calculator, and refractometer calculator. And, the tool that I liked the most, the beer style guides. It also has brewing timers and a feature to email recipe information as a very nicely formatted email. Though the email function is clunky. You must enter your email address into the setup area, and then the email is mailed to you from someplace outside of your iPhone or iPod.
But, I found the interface to be gimmicky and prone to many small glitches. Sometimes the list items would have icons for deleting, and other times they wouldn’t. The list themselves also acted strangely sometimes. Even though I wasn’t crazy about the interface, the tools that it made available made me feel as if my $.99 wasn’t wasted.
The second application that I found is called iBrewMaster (iTunes). The first thing that I noticed was that iBrewMaster’s interface appears to be much more “standard”, and just less clunky. The next difference I noticed was the efficiency of the workflow.
Though the basic concept is the same, the operation of iBrewMaster is a little different than that of Brew Pal. With iBrewMaster you either choose one of the pre-loaded recipes (pictured on the right) or enter your own recipe and then create batches. I like the ability to track the recipe batch from beginning to end, and it would be especially helpful for those that might have multiple batches at various stages.
I started by adding my recipe for imitation Christmas Ale, and I found the interface to be much more streamlined and intuitive than that of Brew Pal. There is a list of all your recipes, and when you wish to add another you click edit and then add a recipe. On the edit screen you can easily change the header information and add, modify or delete components of the recipe. The developer, Joe Cannici, managed to cram a lot of information and editing ability into a small area. It helps you see the complete recipe very quickly
Earlier this week Ars Technica reported that Apple is claiming that jailbreaking iPhones could crash cell phone towers
. Then, yesterday, security researchers reported that they could take control of iPhones via special SMS text messages
. And, these two stories connected for me.
I haven't been able to find any details of the iPhone hack, but from what I gather the special SMS messages cannot be sent from a factory iPhone only from a jail broken one (or presumably a PC with an air card)
Maybe the reason that Apple has not patched this bug is that they are looking for this intersection. I would assume that though it might be technically possible to take out all iPhones in the world, the probability is low. I would imagine that if a carrier saw a patterned flood of text messages they would intervene. Assuming the real impact of this security hole is marginal, it might make it easier for Apple to convince the government that people should not be jail breaking the iPhone. The fear of hackers hijacking phones could also steer public opinion on jail breaking, making it easier to steer government. Most people don't know or care about baseband hacking, but no one wants their cell phone hacked into.
Working for an international company may require setting a printer to print labels (or other types of paper) in multiple standard sizes (e.g. A4 and LETTER). This can be accomplished through SPAD in the tray configuration screen.
Because of limitations in SmartForms we have to take several steps when designing labels to allow output of multiple label sizes. All labels are initially designed in A4 format since it is longer than LETTER. In SPAD the alternate paper size, in our case LETTER, should be assigned to the first paper tray.
If the transaction SPAD is not available, due to security restrictions, then the tray assignments can be viewed using SE16. The table TSP03T shows the output device's tray assignments.
SAP uses a three stage development cycle (at least where I work) which requires developers to make changes in the development system and then users to test the changes in the test system before they can be released into production. In order for changes to get from one system to the next a transport must be made. This post will detail the steps required to create a SAP transport.
The first step is opening the transport manager, which is transaction SE09, in the development system. On the selection screen enter the desired user name and click display. Then, you click on the new request button and choose either customizing or workbench. On the next screen we have special format that we use for the short description:aannnnnnnn_bb_d_wwyy_description
- aa -- SR for helpdesk service request or CR for a project generated request
- nnnnnnnn -- The request number
- bb -- the system, LE for logistics execution, MM for material management, etc.
- d -- C for customizing or W for workbench
- ww -- the calendar week
- yy -- the year
Now we have a request number that can be entered after we save a change using SPRO (for customizing) or after we active an ABAP program or SmartForm.
After the change is assigned to the transport number we go back into SE09, click on the customizing or workbench task click the "Release directly" button (or hit F9). This will prompt to document you change. Once documenting is complete it must be saved. Next, click the request and click "Release directly" again. For programming changes a code review will be necessary, otherwise you will be taken directly to the project selection screen. There is a folder for each of the different SAP areas, and underneath those folders are more folders for the type of change, select the appropriate change type.
Now the transport is nearly ready. At our company we use the RealTech transport manager (transaction code /RTC/TM). Once in the transport manager the author name must be filled in, then hitting enter will open the transport workflow monitor. Items show up here every half hour. Once it shows up, highlighting the line and clicking the "Next status" button (down arrow) will move it to the signature queue. For our company we must now send an email to one of the people who are authorized to sign off on the change and they will release it.
The system will then transport the changes.

It is possible to use SE16 to determine the name of a SmartForm form used by a specific message type. In SE16, view the table TNAPR and make your selection criteria. I normally pick my output type (KSCHL = ZLnn), and my application (KAPPL = V2 for Shipping or V6 for Handling Units). Once you hit F8, you will see the list of results. Under the column "Form name" (SFORM), you will see the name of the SmartForm used for the desired label or output type.

In SE16, by default, the selection screen displays the database field names. This may be good if you are a developer who is familiar with all the database column names, but it makes selection difficult for most people. It is nice to see the description of each of these fields, and there is a simple setting to allow this. From the "Settings" menu select "User parameters...", then on the "Data Browser" tab in the "Keyword" area, select "Filed text" rather than "Field Name".
While reading through the news today two articles caught my attention: "Businesses Need Smartphones, Especially BlackBerry
" (paid subscription) and "Blackberry success with consumers defies recession
". I can't read the first article because it is behind a pay wall, but it seems to suggest that Blackberry is doing well with businesses in spite of the recession. The second article speaks of how well RIM is doing with consumers despite the recession. Together it would seem that RIM is doing great in this recession, but I have my opinion of what is going on.
Prior to the recession my company handed out Blackberrys to anyone with the slightest justification. Now, however, we are pulling those back for anyone without stringent justification. These people have become accustomed to having the capabilities of a smart phone in their pocket, and those who can afford the luxury are purchasing their own. My company is also pulling back regular cell phones, and this is putting more consumers in the market for phones in general. And, naturally, a certain percentage of these consumers will opt for a smart phone.
I think that Blackberry is catching more of this segment than Apple for a couple reasons. First, former business users know Blackberry and are comfortable with them. And secondly, Verizon doesn't carry the iPhone. I have spoken to numerous people who will not get an iPhone simply because they would have to switch to AT&T. If they are concerned about not getting a signal in rural America, then they are on to something. My wife had to go to Coshocton Ohio
, and I went with her. Nowhere in the area did I have any sort of signal, not even a WiFi hotspot. She was fine on her Verizon phone. We were even able to get directions on her phone.
You will notice that I did not mention RIM as being a reason for it's own late success. The company had a great innovation that helped change the cellular landscape, but I don't think that they have done anything truly innovate since introducing the BlackBerry. They are now introducing phones that appear to just be re-branded copies of other successful products. They have a flip style phone, and of course the click-screen Storm.
In my eyes the Storm is a terrible knock off of the iPhone, it doesn't even have WiFi. No WiFi is a deal breaker for me. In fact, if a phone lacks WLAN capabilities, then I don't consider it a smart phone. It ties a person into using a cellular network. For anyone who has traveled outside of the United States and knows what international usage fees are should immediately understand this. My iPhone is more than a cell phone, it is a home Internet device that works off of my home wireless network. I am not certain that RIM understands my perspective on this, even though they do have some phones that offer WiFi.
Blackberry seems to be turning what they have into a sort of commodity, or they are at least competing with other commodity phones. As an investor I don't like to invest in companies that have a commodity type product, especially in the technology sector where a lot of a company's profits must go into developing the next product. From my perspective, Blackberry is heading for a long tail. Motorola and Nokia were once great cellular innovators, but they became complacent and others took them over in the market. I see a parallel with Blackbery.
So, as some are cheering the recent successes of Blackberry, I see the beginning of a long downward trend. I could be wrong, and that is alright with me, but you won't see me investing in RIM anytime soon.
If only Thomas Edison would have joined forces with George Westinghouse, I think that we would be using electricity more efficiently today. From what I understand, Westinghouse's alternating current (AC) is best over long distances, while Edison's direct current (DC) is best over short distances. Alternating current seems to have won out due to the need to transmit electricity over long distances from the power plants to the consumers. And, when that battle was being fought a hundred years ago, either of the technologies worked to accomplish the goals of lighting homes. Now, with the widespread use of direct current consuming devices such as computers and other home electronics, it would seem that using direct current inside a home could be a better idea.
In the modern home there are so many AC/DC converters, those are the small boxes on the end of the power cables that take up so much room in the outlet and frequently get separated from the device it is meant to power. The conversion of alternating current to direct current is decentralized at each of the devices, and each device wastes energy to operate. It would seem more efficient to transmit power from the electric company using alternating current, and then perform a central conversion to direct current. Alternating current is still required for many household devices, so actually both forms would be required.
To me, the present system just seems very inefficient. Consider the example of a home PC. Electricity is generated and then transmitted all the way down to the outlet as alternating current. (Or, if solar panels are being used for power generation, the power is generated in direct current and then converted to alternating current.) Then, the battery backup converts it to direct current to charge the batter. The battery backup has to convert it back to alternating current since that is what the computer expects. Finally, the computer converts the alternating current back to direct current again because that is what the internal electronics require. Each power converts step wastes energy, if nothing else in the form of heat.
Of course not only are homes not designed for this, but neither are electronic devices. A new standard for home wiring would have to be defined to accommodate some form of direct current, possibly in different voltages (5V, 9V, 12V, 24V). There would have to be some sort of standard outlet or receptacle. And, the device manufacturers would have to use new standard plugs. All of these requirements make me believe that changing the system at this point would be nearly impossible. Which is why I wish that Mr. Westinghouse and Mr. Edison would have enjoined their technologies to define a better overall system.
