Negative interface ("will never implement") ?
Hi forum,
I would like to know how you would go to ensure that a class and the classes that may extend it never implement a given interface.
For instance, let's say that I have class that I cannot allow to be serialized.
In this case, apart from writing null writeObject & readObject methods and declaring all members transient, is there any language construct that would allow me to specify which interface not to implement?
Cheers,
adsm
Hi Joachim,
Thank you for your answer.
To answer your question: this is just an example. I have picked Serializable because implementing this interface has specific requirements by itself, and these requirements implementation may be "tweaked" to effectively render a class un-serializable. I was just looking for a language feature that would allow me to specify that a class and its children may never implement a given interface. I haven't found one, never heard of one and you kindly confirmed that.
Cheers,
adsm

Why I will never shop at Best buy again, EVER!
I will never shop at best buy again! Over the years I have made sure to buy anything tech at best buy. I was a premier member for several years. Ive bought MacBook’s, Tvs, tablets, all kinds of tech. I used to send my customers to best buy to purchase all things tech because of the accidental warranty. Ive used the accidental warranty A LOT. It has been a great blessing as I am a darn cluts! Ive tripped and dropped MacBook’s, even had one randomly crack right across the screen. Ive had some pretty stupid battles with cuomer services In electronics that have failed. Im a network engineer with a degree in my field nd love all things tech. I one time put a solid state drive in my last mac which shorted out. I was told it would not be covered because I shouldn’t have changed the hard drive as I was not qualified. This flat out ticked me off more than anything. After speaking with their legal department about how the book that cam with the darn laptop they sold me had section on how to change the HDD and this would not void the warrenty. I decicded to go to best buy to swap it instead of apple. Which was a MAJOR MISTAKE. Not only did they junk it out on me but I had to pay to have it replaced with in its first year!!! I never even thought of the manufacturer warranty as it sent me into a MAD war path. So I reckon I deserved the $300 dollar loss…I was able to recover from most of this. I realize that most of the geek squad crew lacks education in the technology field. One of the most amazing feats of the local geek squad was when I was using canned air to blow the keyboard out on the mac. Yip it be my luck one blew off. Brought to best buy. Got a cell phone call before home that it was fixed. Now I had researched these keyboards and what was required to replace them. This was not a snap it back on feature. Went and picked it up. Was told by a supervisor named Paul that they had a keyboard in stock. Got home (youp silly me) opened her up. The key was crooked, it was even loose. Pressed it a couple time. Popped off with a string y substance. Yup they glued the darnkey on. MIND BLOWN
Anyway through the years and the issues I just kept piling up. My wife bought me an alienware computer for Christmas. I fell in love!! I loved every bit of it. Much to my despair I left it on the table one day and my very curious 2 yearold yanked on the cord and down it came into many pieces. It never ran the same again. At this point I was bed ridden due to a rare disease. I jad just finished a series of 14 surgeries and was recovering for a few months or so. My wife bought it to Best buy they had decided they wouldn’t fix it on the warranty that it was cheaper to replace. My wife called, and told me . I was a bit disappointed but I said as long as it works im fine. Well the phone rang a few min later, my wife, the manager did not have another alien ware, I told her I would wait and asked if she could have them order it. We were told best buy no longer carries them. So we would need to pick a different one. I was really upset. The had nothing equivalent to my alienware for playing games. I will be in a chair or bed for the majority of my life at this point. So I had gotten into PC gaming and invested a bit of cash into software. SO they hooked me up with an ASUS that was supposed to be equivalent of my alien ware. Of course that wasn’t the case. We had been snookered. Some of my games did run. Well, I had a working computer. Well like an idiot I had spilled water on it in a few months. Its was so dang slow. I sent it off to geek squad 4 times. They kept arguing with me So for a few months I used a computer that was slower than a P4. Well I got a new one. Now keep in mind each time its replaced I have to pay cash. For the warranty. I had spent another couple of thousand on warranty issues when these idiots screwed up. Granted a couple of times for the spill were my fault but gluing a darnkey on my mac??? I had to pay almost 300 to insure it!!! CUZ THEY GLUED A KEY ON. BULL CRAP. Well when I got the new one it took 2 days to reload my software, welp wouldn’t you know it was defected? Wife brought it back sent it off nothing wrong. They JUNKED IT AGAIN. ANOTHER almost $300 BUCKS FOR A WARRENTY!!!! But you know what, it was my darn fault for not realizing they were stealing and using my wifes lack of knowledge. Perhaps for me it was all the pain killers, I don’t know. But what I can say, I got MAD and had My wife put me on speaker phone as I lost my composure. Well 3 more ASUS same model, same store, all within a DAY had defects, I was so darn angryI told my wife to get our money back wed go buy elsewhere. Well they didn’t want to do that!!!!! They wanted to give me less than what my aleinware cost!!! I already took a loss with the friggin ASUS 3 computer in a matter of days, wouldn’t work. Which brings us to today. Computer sucks, wont run new games. I got screwed by best buy. Yes it is my fault I was stuck in bed after surgery. But that’s why I paid an extra $300 for that reason and knowing with 4 kids and a clutz I needed to buy that protection. So I am thankful for it. But I know Geeksquad and best buy took advantage of my wife who is not computer literate. I haven’t been able to get up for long. But soon I will take this asus back to the store AGAIN. Once I get it replaced I will sell it on amazon or craigslist in its sealed state!
So this is why I will never shop best buy again. Dell offers the same warranty. Not only is it cheaper, but they send our parts next day and a tech come to you next day and fixes it at your home. So hopefully by weeks end ill have the strength to go into best buy I will ne returning 2 wireless a routers and any other things I can. Then I will terminate my business with them. I can’t even believe that the 3 months I was under hospital care that best buy would use a pregnant women as such. But now they have lost a lifetime customer. I amGreetings cm6pack,
Welcome to the forum! After reading through this debacle with your Alienware and ASUS laptops, I can understand why you would be frustrated with the outcome. After having so many exchanges, who wouldn't be disappointed in the experience you have described? I am truly sorry for any inconvenience or discouragement these exchanges may have caused you.
When a device is exchanged under the manufacturer’s warranty, the Geek Squad Protection plan may carry over to the new device under some circumstances. However, if it is exchanged under the Geek Squad Protection plan for accidental damage, per the terms and conditions of the Geek Squad Protection plan, the plan is considered fulfilled and a new plan must be purchased to cover the new device. That being said, unfortunately it seems that the store would have been correct in fulfilling your some of the previous plans if the device was exchanged due to accidental damage, requiring a new one be purchased.
I was able to locate the receipts form these exchanges using the email address you registered on the forum, and I am sending you a private message with some further information in regards to this issue. You can check your private messages by signing into the forum and clicking the envelope icon in the top right corner of the page.

I will never buy another HP Product Again!
I tried to get some help with an issue that I have been having and could not decide where the issue fit best so I posted it over multiple areas ... NOT to SPAM, but because it did not fit into anyone area ... here it is listed below;
I have a HP Pavilion a6152n PC purchased in Sept. 07, running 32 bit Vista
For a while my web cam worked fine, but now, while I can see the web cam, those on-line using such services any Skype and Yahoo. can NOT.
The audio continues work fine and CAN be heard by the other party ... the problem is with the video.
I even bought a new web cam thinking maybe it was a problem with the cam, but the same problem repeats on THREE different web cams, one microsoft and two Logitech, so if must be some kind of software(hardware) problem with the computer.
I am hoping it is an easy fix ... I just have no idea what it is, Please help!
Thanks so much and have a good day!
Not one area ... could be hardware, could be software, could be 'other' ... I wanted to get as many eyes as I could so maybe someone would have a solution.
No solutions from HP ... just my posts locked.
That is NOT the kind of customer support that I deserve and I will be taking my future business to other providers.
My suggestion is that HP have both more help and more respect for its clientele.
Thank you for reading this!
Message Edited by Clyatt on 06-01-2009 05:16 PMI have had problems with HP from day one and HP would not-could not solve my problem so I lived with it for several years. After intensive searching for help from HP, I took my HP products off line and bought a Brother AIO and booted it up and guess what....IT WORKED PERFECTLY the first time. It finally scanned to Word and I could edit my files. NEVER could do that wtih the HP G85 AIO which was very expensive and the HP 2400 PhotoJet which was expensive at the time. Not only would HP refuse to help me solve the problems with my AIOs, HP wanted money UPFRONT just to ascertain what might be the problem. I have had my home office setup for consulting but was limited as to what I could do with the HP products but now I am certain that with the Brother, I can do all I need to make clients happy and bring in an income. I, too, will never buy another HP product again. And by the way, Wendy, get the hell off the forum....you are an HP employer and are as useless as your products. You should be solving our problems with your products rather than talking gibberish.

WILL NEVER BUY AN HP PRODUCT AGAIN!
I am incredibly unsatisfied with HP. I bought my laptop (a dv7 4077cl) from Sam's Club a little over a year ago (in October of 2010), and over Thanksgiving the heat sink and fan assembly began to go bad. I am in graduate school right now, so I let it go until finals week was over, and then took it home to see about getting it fixed. After having tried Staples, Best Buy, and various computer stores to find a replacement heat sink/fan assembly, but couldn't. So, I decided to try and call HP directly in order to get a replacement part, therefore I could fix it myself and save myself the $250+ they would charge me to fix it. First, the computer service technician told me they would need to replace the entire motherboard, which is blatantly untrue. Then, we called back and were told that those parts were not available for customers to purchase (however, hard drives, moniters, etc. were). I asked if I were to take it to a computer store, if they could get the part, and the representitive at HP stated that no, the only way to fix my laptop was to go through them directly. It is absolutely RIDICULOUS that a) my laptop has hardware that goes bad after just over a year of use and that b) the only place we can get the part is through HP, for a crazy amount of money. My family has bought roughly 6 or 7 computers from HP, as well as family friends, and after this experience I will never EVER buy another HP laptop again. I will also tell every single person I know about this experience and urge them not to purchase an HP laptop. This experience has been way more of a headache than it needs to be, and I can not believe the amount of trouble this has caused over a small part that needs to be replaced. If you are considering buying a laptop, I urge you to reconsider and purchase a Dell or a Mac, because HP clearly does not stand behind their products.
Dont feel bad.
I tried contacting HP service today about an issue I'm having with a Lap Top I purchased for my son last Christmas. The display has taken a dump and now the Hard Drive has crashed. I called a month ago. First I get that the Lap Top was out of warranty... I pourchased it on 11/26/2010 and they toldf me the warranty had expired ion July. I was told I needed to send in proof of purchase to verify the warranty period, but never recieved the email they claim to have sent. Now its really out of warranty and they wont help! I asked to speak to a supervisor and was told NO! can you beleive it! NO! if I wanted to have my lap top repaired I would have to pay for it! HP SUCKS! I own 5 HP computers 2 HP Printers, and I will Never buy another HP product again! Way to Go HP Customer service at its best!

I'm new to using Time Machine - I'm making my first backup right now - and I have a few concerns.
So let's say my precious photos are taking up most of my Mac's hard drive space. I back them up with Time Machine on an external hard drive. After that, I want to delete my photos from my Mac because I want more space and my photos are now stored in the external hard drive. I have a few questions about that.
First, does Time Machine's backup system follow the same concept as having extra storage (so would this be a reasonable decision to make)?
Second, if it does, then could I access/open these photos from Time Machine's backup anytime I want?
Third, would I need to use the restore backup function of Time Machine every time I want to open my photos are there alternative ways of accessing my photos, like through opening directory paths to the photos?
Lastly, when the external hard drive becomes full and Time Machine wants to delete my oldest backup files, what can I do to ensure that these photos will never get deleted unless I manually do it? Like, is there a way to lock and secure these files? Or, is it like if these photos are the only copies saved in the backup, I can rest assure that Time Machine will never delete them?

Since my new external hard drive is have a lot of space, I'm thinking of splitting it for Time Machine and external storage.
This is a common mistake and I highly advise against it.
1: TimeMachine saves states of changes and thus requires more room on the TM drive than the boot drive it's backing up.
2: Something happens to the TM drive, loss, theft, dropped, power surge, etc., you lose both backups.
3: The storage drive might become a portable need, with it being on the TM drive, now your increasing the risk to the TM backup that something could happen to it along with the storage drive, due to increased movement.

Is "Broadcast Safe" necessary if the output will never be broadcast?
I'm doing a project whose final output will be a set of DVD's which will never be broadcast. I really like the color look I've achieved for my clips, but when I check my scopes, they're outside broadcast safe, both up and down. If the output will never be broadcast, do I need to adjust these for broadcast safe?
Also, to get the best for the output, which settings for YUV, etc. should I use to have the DVD's match what I'm seeing in FCP?
Just a bit of additional information, I'm making the assumption that most if not all of the ultimate viewers of the project will be viewing it on modern HD sets. Does that also make a difference to my final output settings?
Thanks.You must view FCP's output on a calibrated, professional broadcast monitor to assess the "look".
Computer monitors do not provide a true indication of how your movie will appear on a consumer television.
Try to find two consumer televisions that are accurately and identically adjusted. It is very unlikely.
While there is some degree of tolerance and there's not much chance of you blowing up someone's TV these days, you should at least use the "Normal" settings in the broadcast safe filter.
As an example. whites and yellows that are too bright can "crossover" and cause an annoying buzzing sound in the audio as well as being unpleasant to look at. -
I will NEVER buy a Thinkpad again :-(
So I opened my briefcase this morning and took out my Thinkpad T61p.
It was warm, which worried me - it has always run very hot and it doesn't seem to shut down all the time when I close it. (note: with Win 7 my other one does).
So I opened it up and the screen was black on half of it, garbled on the other half and had a "crack" down the middle of it.
I called tech support. What they told me made me decide I will never buy another Thinkpad again (15 year devoted customer here who loved Thinkpads).
They said:
- You must have dropped it. It is NOT covered under warranty. i.e. You are lying.
- You can send it to us to fix it. You must give us your credit card number and pre-approve a $950 charge to replace the screen.
I told them that for less than $750 I could buy an entire new Thinkpad with an equivalent monitor and that this was ridiculous. They escalated it and supposedly Lenovo will call me (there is a prior deal between IBM and Lenovo setting prices for this) within two days.
I checked prices locally for replacing monitors - it is $179 for parts and labor.
Lenovo has ruined the Thinkpad brand.
I doubt they will call me within 2 days. Prior to this any time I had a hardware problem they were great - that is why I have purchased 8 Thinkpads in the last 15 years.
This is a lesson in how to lose a long-term customer who was completely loyal.
Note from Moderator: A comment which violated the forum rules was removed.Did you put a switched on laptop in your carry case? Also if you have a cracked LCD, there is little chance that it will be covered under warranty unless you have accidental protection warranty, no laptop company covers LCD cracks in their laptop on standard warranty term, whether it is IBM or Lenovo.
With the full magnesium rollcage, it would take a large force to actually crack the LCD. It is a standard policy to charge customer a service fee of around 500 to 750 dollars when the company suspects there is user damage to their laptop. It is a policy from IBM days.
