Snapchat CEO Says The App Was Only Supposed To Be For Rich People

Snapchat CEO Says The App Was Only Supposed To Be For Rich People
Some interesting new information has come to light In an ongoing lawsuit between Snapchat and an employee who believes
he was wrongfully terminated.
The employee is Anthony Pompliano who was recruited from Facebook to assist the company in growing.
One of his initial concerns was that the
app wasn’t doing too well in overseas countries. When presented with the concern, Snapchat CEO
Evan Spiegal allegedly said that the app is only
for rich people and that he didn’t want to expand into “poor” countries like India and
Spain before storming out of a meeting.
If true, the statement sounds really naive of the CEO now that the company has gone public and has become one of the biggest social networks in the mobile world. Had the app truly only been for rich people, it wouldn’t have seen nearly as much growth and Snapchat wouldn’t have
been able to get to the
point where they could do an IPO. There’s also the matter that there’s
very little “poor” about countries like Spain, and while India may indeed be a developing market, it’s progressing faster than every other major country in the world.
Other allegations Pompliano presented were that the company
was routinely lying about usage numbers, such as 40% customer retention and 87% application turnover, figures which Pompliano
allege were greatly exaggerated, and something that could
cause an issue with advertisers down the
line.
There’s also a note about a shady attempt
to learn about Facebook’s organizational structure despite Pompliano having a known confidentiality
agreement in place, as
well as accusations of Snapchat hindering his ability to find new work by blacklisting him, a practice where former employers wrongly provide bad feedback about an individual to companies looking into
hiring them.
For Snapchat’s end, they contend that Pompliano’s claims about his knowledge of
their “current” user metrics are merely made up. Which Snapchat has fought to keep redacted but recently relaxed their stance in light of their recent IPO.

Differences Between GSM Network And CDMA Network

Differences Between GSM Network And CDMA Network
You should know that each successor to the mobile network technology has one numeric number followed by the alphabet ‘G’. This is of the form ‘vG’. So, 2G means 2nd generation, 3G means 3rd generation, 4G means 4th generation and so on. Each generation is more advanced than the previous standard. Which is obvious, isn’t it?
Currently, 4G is the latest standard but many big organizations have already started their work on the upcoming 5G wireless technology.
GSM Network vs. CDMA Network

GSM and CDMA (Code Division Multiple Access) are the two most popular radio standards used in the mobile world. Both technologies offer similar features but CDMA is more popular in the U.S. than the rest of the world. Most of the European and Asian countries use GSM networks. Some people might tell you that CDMA is better than the GSM or vice-versa but it is not true.

U.S. operators moved to the CDMA technology when GSM technology was in a nascent stage but now that GSM technology has caught up with CDMA, the U.S. operators don’t feel the need to shift to GSM technologies. Most of the telecom companies in the rest of the world utilize the GSM technology for rolling out their networks, and they also don’t feel the need to migrate to CDMA technology.
So, when you go out in the market for buying a new phone, you will see that the available GSM phone models are much more in number than the CDMA models. You know the reason behind this.
Now, let’s discuss each generation of network in detail along with its associated network standards:
1. 2G – 2G is the first digital mobile network technology. 1G was analog technology and was very inefficient. 2G brought support for SMS and mobile internet. GSM (Global System for Mobile communication) uses GPRS (General Packet Radio Service) and EDGE (Enhanced Data rates for GSM Evolution) technology for internet access, while the CDMA technology uses RTT (Radio Transmission Technology) for providing 2G internet access.
2. 3G – It is the first mobile network technology to provide access to high-speed broadband like internet. Live video streaming, video chatting was first made possible by the 3G network technologies. GSM networks use WCDMA (Wideband Code Division Multiple Access) or UMTS (Universal Mobile Telecommunications Service), HSPA (High Speed Packet Access), and HSPA+ technologies for rolling out 3G networks. The CDMA networks on the other hand, use EvDO (Evolution-Data Optimized) technology for deploying 3G networks.
3. 4G – It is the latest generation of mobile wireless technology and offers the best data speed. It is made for providing mobile broadband access and can be used for data intensive applications like watching high-definition TV on mobile, cloud computing etc. 4G network is currently deployed using LTE (Long Term Evolution) and WiMAX (Worldwide Interoperability for Microwave Access) technologies. As per the ITU-R (International Telecommunication Union-Radio Communication Sector), any network having a peak download rate of 100 Mbps for high mobility and up to 1 Gbps for stationary wireless access will be termed as a 4G network. LTE, LTE-A (LTE Advanced), WiMAX Rel 1, and WiMAX Rel 2 are some of the popular 4G network standards. 4G networks are based on neither GSM nor CDMA technology, but are instead based on OFDMA, SC-FDMA That’s why the basic 4G networks can’t make voice calls and a new standard called VoLTEis being deployed to make that possible.

The following table lists down the speed ratings of each of these network technologies.
Differences Between 2G 3G 4G HSPA LTE EVDO GPRS EDGE
Generation Standard Radio Maximum Theoretical Download Speed Maximum Theoretical Upload Speed
2G GPRS GSM Up to 80 Kbps (Class 10) Up to 20 Kbps
2G EDGE GSM Up to 236.8 Kbps Up to 59.2 Kbps
2G 1xRTT CDMA Up to 0.3 Mb Up to 0.15 Mbps
3G UMTS (WCDMA) GSM Up to 384 Kbps Up to 384 Kbps
3G HSPA GSM Upto 14.4 Mbps Up to 5.76 Mbps
3G HSPA+ GSM Upto 42 Mbps Up to 11.5 Mbps
3G EvDO Rev. A CDMA Up to 3.1 Mbps Up to 1.8 Mbp
3G EvDO Rev. B CDMA Up to 4.9xN MbpsN: number 1.25 MHz carriers Up to 1.8xN Mbps
4G LTE OFDMA Up to 100 Mbps (Cat3) Up to 50 Mbps (Cat4)
4G LTE-A OFDMA, SC-FDMA Up to 1 Gbps Up to 500 Mbps
4G WiMAX Rel. 1 OFDMA Up to 30-40 Mbps Up to 17 Mbps
4G WiMAX Rel. 2 OFDMA Up to 1 Gbps Up to 376 Mbps

Differences between byte and bits 

All of the above-mentioned speeds are theoretical values derived for different standards for ideal scenarios. Nothing is ideal in real world. Furthermore, connection throttling by the operator, network congestion, and quality of service also affect the actual speed that the user gets.
‘B’ is not the same as ‘b’
This is a common mistake made by many non-technical people while mentioning the speed of their internet connection.
For network configurations, ‘B’ is known as byte and ‘b’ is known as bit.
1 byte (B) = 8 bits (b)
ISPs (Internet Service Providers) and modem manufacturers specify the speed in bps (bits/second), whereas the internet download managers and other file sharing programs denote the speed in Bps (bytes/sec).
For S.I. system:
1 Mega = 1,000,000
But for Windows computer system (binary):
1 mega = 2^20= 1,048,576.
That’s why:
A download speed of 1 Mbps = 1024 Kbps = (1024/cool KBps = 128 KBps
Now, that you know what to expect from each network technology, there is one more thing that should be kept in mind while selecting a phone for international roaming. Different frequency bands are used for deploying these mobile networks across different parts of the world. So, a 4G phone launched for the U.S. market might not be able to latch onto other countries 4G networks.
That’s why it is always wise to take a look at the frequencies supported by the phone and your network operator before making a buying decision.

Warning! Read What Too Much Masturbation Can Do to Your P*nis

Warning! Read What Too Much Masturbation Can Do to Your P*nis

Warning! Read What Too Much Masturbation Can Do to Your P*nis

0

Many men do not know that they are putting themselves at great risk each time they begin to pleasure themselves. Guys, read up what over masturbation can do to your p*nis.

Over stimulation of the p*nis can lead to persistent softness of an erection, while the disappearance of a morning erection can signify a hormonal imbalance. Weak erections can vary, from poor blood circulation to anxiety issues, but for men who over masturbate, the weakness can occur because of a hormonal imbalance.

Hormonal Reserve

Think of s*x as a battery. The more you use it, the faster you lose it. An erection occurs because of a healthy dosage of hormones and neurotransmitters. The urge for s*x starts with testosterone. But men who ejaculate often lose testosterone faster than their bodies can replenish it. With little testosterone, erections become weaker.
Meanwhile, dopamine must be released to stimulate the p*nis, while acetylcholine must be present to keep the “excitement” level high. Nitric oxide, a signaling chemical, must also appear in order to provide the proper signaling between the brain and the p*nis for a healthy erection. Over masturbation depletes all of these neurochemicals.
Lowered dopamine requires more stimulation to stay “hard”, while decreased acetylcholine levels ruin the flow of blood to maintain an erection. Depleted nitric oxide levels lead to a decrease in communication between the brain and p*nis.
Regaining the Proper Hormones
For hormones to return to their normal state, men must refrain from masturbating as often. The individual who has grown addicted to the activity may have trouble quitting. Still, an individual should aim to quit gradually. Next, taking hormonal supplements can help stabilize testosterone and neurotransmitter production for a healthy erection.


If you suffer from weak erections, take Botanical Solutions for Erectile Dysfunction to help stabilize your production of nitric oxide and to increase the elasticity of blood vessels for improved erection quality.
