Other / Off-topic / Re: Question About How to Limit Access to a WordPress Webpage
|
on: December 28, 2013, 01:35:20 AM

As much time as I spend on this forum I thought I would ask this elementary question that I cannot seem to find an answer too. I think the main reason I cannot find the answer to the question is because im not inputting the proper keywords into google. So even if you can throw some terminology at me to use as keywords this would be great. Ive been procrastinating starting a thread with this question for some time so since then I think that I found an answer that could be the most ideal solution but Im sure there are other solutions.
Let me tell you what im trying to do. I manage a small businesses wordpress website. They want to implement coupons. Ok this is no problem. Ill style up a basic coupon voucher, save it as a PDF and provide a download link. But they want to limit the coupon to one coupon per customer for a specific time period. How do I go about limiting 1 coupon per customer and for a set time period? It would be awesome to be able to tally the number of claimed coupons but I assume the easiest way would be through google analytics.
I was using woobox, which at the bare minimum provided what we needed but since then woobox starting charging a subscription fee. I am assuming that the best implementation of limiting access will need to be done via the users IP address. So then cookies come to mind.
I could implement some sort of user registration that would lead them to the coupon page but the company felt that would deter the overall number of claimed coupons. another idea was to require the customer to enter in an email to get to the download page so the question could be how to limit content by email address.
So my question is, what are some other ways to implement limiting access to a webpage and/or download link besides cookies...or is this the best way? If i set something up limiting by email address i assume that a database would be required so cookie may be the less amount of set up work.
Do any of you know of any wordpress plugins or scripts that I can modify so that i can accomplish this.
I am pretty much content tracking visits and such through google anlaytics but if you knew of a better way this is a plus. the company wants to be able to view the claimed number of coupons at any given time. I could do this through google analytics but I know they are going to get all stressed having to think a little bit navigating a section of Google analytics.
A long winded general question indeed but I appreciate any response and your time reading through this.
Hunting now to see if I can provide a solution. I'm pretty well-versed with WP.

They don't take credit cards. So they likely don't have computers set up at their locations? Or they simply enjoy the security of receiving cash in hand. Bitcoin can't replicate that - they need computers at their locations, and they need their customers to stick around for a few minutes to get some confirmations that their spends are accepted by the network. https://play.google.com/store/apps/details?id=de.schildbach.wallet&hl=enFor small purchases, accepting at 0 confirmations is low-risk. Having set up at the old Lakewood Antiques Market up to the last show, I say this is the best way to go--0 confirmations on low-end wares. For any high-end purchases, maybe wait for one confirmation. It's not uncommon for shoppers to have you hold an item at flea markets once paid for while they tend to other shopping thus, if this were the case, more confirmations would arrive. Yes, there's many a unsavory characters that feed off flea markets, but double spending bitcoins will probably not be on their radar given the amount of energy needed to pull it off. Basically, they're in a low-tech-state-o'-mind. ~TMI BTCITW

There are two critical flaws in Bitcoin which doom it.
1. Transaction fees are not zero and mining of new coins does not sustain mining perpetually.
2. Mining is not CPU-only (along with botnet resistant) so that it is widespread and available to everyone.
Actually there is a third flaw with lack of strong anonymity, which dooms it as well to takeover by taxation authorities.
1. This will be a serious concern in the future, when the value of BTC rises. 2. Don't see much problem with this 3. If you use TOR and a BTC mixer, it will be very hard for the tax authorities to trace you. Jehovah's Witnesses don't join the military, work at factories that produce weapons of mass destruction, i.e. guns, nor salute their state flag. Yet, they're bound by their doctrine to pay all their taxes due in a timely fashion.

He said imagine, not "is this possible?"
I believe tom is giving us a thought exercise, isn't this what the forums are for. Thinking up situations that could possibly happen, and what those consequences would be.
I for one think that the argument is a valid one. As the price rises, the more miners jump on board. The more miners, the difficulty increases. Difficulty increases, miners want a price increase to cover it. So on and so forth. It all started about a month after the reward halving, and then when ASICs hit the scene then the price skyrocketed.
It's not an instant effect, but it's there.
I assume when you said tom you meant the OP? We can all dream up situations that could possibly happen and then concoct some kind of thought exercise, sure. But what's the point in dreaming up a totally implausible thought exercise? There is no worth to it. What is far more useful is to imagine a scenario that could realistically happen and then explore around that point. The reason this situation is implausible is because the time it would take to get to a $1million per btc price tag would allow for significant technological developments, making mining more efficient as well as energy infrastructure, energy generation etc. There is simply no point in conjecturing around something which is so far into the future that you cannot even begin to comprehend how different even the most basic functions of life will be. If Bitcoin does have an effect comparable to the Internet, then the world we will be inhabiting in 15 years time (when the price per bitcoin will still not be anywhere near $1million) will be totally different, having gone through a new round of innovation and economic evolution. Then imagine how it will look if we do reach 1btc=$1million. I cannot even begin to comprehend what that world would look like, hence this debate is pointless. Anyway, I realise I'm just being annoying now so I'll bow out and leave you to your conjecturing. Happy Christmas! Tom For me, it was worth reading your well-written post (seriously), and coming to the realization that you may have penned other nuggets that I may have missed. I can't count how many times I've read threads where the OP was skewed in some way, yet subsequent posts offered up golden kennels. Likewise, how many threads have you (the reader) stumbled upon where the OP was spot on (via Google, I just learnt that a hyphen is not needed) and well-articulated, yet subsequent posts spanning several pages offered nothing much of substance? Rare, but probably has happened. ~TMI BTCITW

Some more inquiries: From: Steve S. Dmitry, My nonprofit Upaya Social Ventures is working to create dignified jobs in India's poorest slums. Our organization began accepting bitcoin a few weeks ago and a friend recently told me about Bitcoin 100. I would love the opportunity to talk about possibly including Upaya on your site - please let me know if there is any additional information from me and I will be happy to send it along. Thanks and looking forward to speaking soon. Happy holidays! - Steve Steve Schwartz Director, Strategy & Operations Upaya Social Ventures Aspiring Entrepreneurs, Inspiring Outcomes Microlending site. I'm gonna stay neutral on this one. Ca fait longtemps que je n'ai pas parlé français. Avoir du plaisir en revue celui-ci, Phinneas From: erik To: me, Esther Hi Esther, Please meet my friend Dmitry. We met in DC in a group of people enthusiastic about innovative technologies that improve our society. He now runs a foundation that is looking for worthy nonprofits to donate to. I am also getting him in touch with over a dozen more organizations I have been connected to. I think he will really appreciate Naija Worldwide Charities. Dmitry's foundation is called BitCoin100. They arose out of the generosity of a few early adopters of an amazing currency called BitCoins (if you haven't heard of them, this might help) to promote the value of the currency for nonprofits: when donors make their donations in BitCoins, the recipient nonprofit keeps 100% (hence the name). None of the funds are lost to credit card or processing fees. BitCoin100 donates $1,000 to selected nonprofits who agree to accept the currency on their donation page. It doesn't take much work to get it set up, but I know the money could do a lot of good for your genuine and altruistic efforts. @Dmitry, Esther is a friend of mine with a great passion for improving lives of others. I met her in DC while seeking architectural and planning projects worth giving a helpful hand to and since then I have been collaborating with her on designing a hospital project in Nigeria. She is a passionate educator, and an inspirational leader. She founded Naija World Charities in 2008 and received national and international recognition since then. I know they could do a lot of good with $1,000 and I thank you kindly for your time helping out! Good luck! Hello Erick, Rassa, Thanks Erik for the wonderful introduction, we do the best we can to help those less fortunate than us but it has not been easy. There are so many hurting people around the world whose lives will be improved just with a little help. We would love to be the change agent, the catalyst used in making that difference but at times it feels like our hands are tied due to funding. We work through the grassroots so we meet these people face-to-face, we eat with them sleep on their floors and listen to their stories. Rassa, good to finally make contact with you. Erik has spoken so much about you and the wonderful work you are doing, I feel like I already know. I look forward to building on this new relationship and maybe collaborating with you in some of the programs that we do. Looking forward to hearing from you soon.
Seems pretty good. Doubt there'll be any issues with this one either. And last one, From: santa esecreto hello dmitry. we've run an ad-free, not-for-profit, global-youth-oriented news & education service since 2005 called spectre. begun as a community email list, spectre became popular enough to grew in unexpected ways, including requests for reprints from nonsense nyc, arthurmag & motherboard, plus viral media tools like facebook, twitter, pinboard, pinterest, etc. the mission of the project is simple: to spread good ideas. as news curators we have become many people's favorite news source, in part because we do this mostly without editorializing. the main portal to much of that material can be found here, beloved in certain circles: http://spectrevision.nethttp://spectrevision.net/2013/12/10/price-discovery/anyway we recently became enamored with bitcoin and added donation and mining options to our site. so we are very excited to see your offer. do we in fact qualify? we hope so, and would be happy to explain ourselves further as needed. looking thru your grantees, we too are running a non-commercial education platform like antiwar.com or khan academy. we are a very small group of people, all doing this without much of any financial support since well, ever, so joining this new bitcoin economy is a somewhat exciting prospect please let us know if theres more information you need, and thank you for considering us santa - Please contact Dmitry (Rassah) at Rassah@xnicole.com with any questions or concerns and, moreover, if you oversee, or know of an NPO that could use a $1,000 USD endowment from Bitcoin 100. Bitcoin100 exists specifically to convince new charities to start accepting bitcoin donations. Many Bitcoin enthusiasts of various backgrounds from around the world have supported this project with time, effort and/or bitcoins. In order to use donated funds in a manner consistent with donor expectations, Bitcoin100 donates the Bitcoin equivalent of $1000 to non-political, secular charities that prominently display an option for supporters to contribute via Bitcoin on their website. Not sure about this one. Phinn, what questions would you ask them? http://spectrevision.nethttp://spectrevision.overblog.com/the-bitcoin-network-is-now-more-powerful-than-the-top-500-supercomputers-combinedLooks like they've been aware of Bitcoin since at least May of this year, thus probably won't qualify, sad to say. ~Bruno Kucinskas

Hey again, I'm actually going to meet up with my friend who runs this organization tomorrow, I'll speak to him about the idea of taking bitcoin, see what his thinks about it. If he's down with it, we'll need to think of what the best way to implement it. Hello, I'm the one who is suggesting www.volodalen.asso.fr above. If there are any questions maybe I can answer them. Thanks, Bruce volodalen.asso.fr Inaonekana faini, Rassah. Swahili

Hello Rassah, Just to let you know that I have finally set up the Bitpay account for Naija Worldwide Charities and we are now ready. Thanks for your patience, NWC really does very essential programs for the less-privileged in our communities and could use all the help it can get.
I guess soon as they add the bitcoin button to their donation page, and soon as Phinn gets to review and approve them, I'll send the money http://www.linkedin.com/pub/esther-ejim/27/952/a93It's a go! I like them, too. ~Bruno Kucinskas

Other / CPU/GPU Bitcoin mining hardware / Re: Did either cointerra or hashfast ship yet

on: December 27, 2013, 03:51:57 AM

Nope. KNC is the only 28 NM box out there that I know of.
Of course who knows what is mining away that isn't for sale.
Ignore terrahasher. he's a conspiracy theorist. neither hashfast nor cointerra have yet shipped though both are imminent. hashfast has chips back from the fab but seems to be having other production problems and has yet to show it working and to announce final performance & power consumption figures. Its about two months late, but still (with days to go) within their contractual delivery period. theyre still claiming they will ship the batch 1 customers before year end (and i hope they do as im one of them!) though its really tight to achieve that. There was a trip report by Eligius a few days ago that showed a photo of a system running at 424 GH... which seems to be pretty much on spec. it was claimed to be underclocked, but we're not sure, as 424 GH was the previously announced spec in their own documents. Hopefully there's still margin for overclocking as well as their web site says they got it running at 500 GH and claims its the fastest bitcoin mining chip in the world but there's not yet an official demonstration and scant details of that feat. since cointerra's is specced to run at > 500 GH, that claim may be true this week... cointerra are expecting chips back any day now (late dec - according to their schedule) and are expected to deliver the january production batch pretty much on time (ie: in january - though the original late december batch has pretty much been moved into january with the customers' blessing and some compensation from ct). we're expecting them to show a working box within the next couple of weeks (early jan). theyve shown everything else is done... ie: box, board, cooling system etc so confidence is good at this point that they will deliver in jan. there've been a few trip reports, including one i did a couple of weeks ago (on my way to the Inside Bitcoins conference in vegas) At this point, the only people who have successfully delivered a working 28nm product are KnC... and even they arent shipping right now this minute. They say theyre waiting for hashfast to deliver before they resume shipments. I have several Jupiters and theyve been very good for me... and theyre busy hashing away. im impressed with KnC's attention to detail and customer focussed attitude. Theyve done a lot to earn their excellent reputation and they proved it was possible to go from Tapeout to Customer deliveries in two months. But their products are more expensive (measured in $ per GH) than the newer competition... so there is a dilemma... to order from the proven reliable people or wait for the newer more competitive people. I liked you the moment you sat across from me at CoinTerra's lab. Nice post. Also, glad to see you in LV, albeit I was donning a pink tutu like I told you I was going to do while in Austin. ~TMI BTCITW

I got the dreaded message... Coinbase
On Dec 19, 2013 you purchased 0.10 BTC via bank transfer for $70.28. Unfortunately, we have decided to cancel this order because it appears to be high risk. We do not send out any bitcoins on high risk transactions, and you will receive a refund to your bank account in 3-4 business days. Please understand that we do this to keep the community safe and avoid fraudulent transactions. Apologies if you are one of the good users who gets caught up in this preventative measure - we don't get it right 100% of the time, but we need to be cautious when it comes to preventing fraud. You may have more luck trying again in a few weeks. Best of luck and thank you for trying Coinbase. Kind regards, The Coinbase Team
so thats great if they really do refund me, in the meantime if btc goes up and I want to sell what other vendors can I use? Thanks
Hopefully, you realized your mistake. Next time don't make such a large purchase. Work your way up to such bigger purchases, thus operating under the radar. Consider buying only seven or eight dollars worth at a time, then later, BAM!, a $95 USD purchase. Coinbase won't know what hit them. ~TMI BTCITW
